Using the Intelligent Search
Rapid, in-depth results using minimum effort,
bringing you the perfect hand dryer, every time!

Page5
In just 30 seconds, you can make sure any search is specific to the client, location and end user
based on the footfall in the building, the type of building and the overall requirements of the project.
Basically, you can use this search to give thorough and specific results, as well as provide calculations
that would take you a while to research if you had to do it manually.
Intelligent Search
Use the intelligent search to enter the following information:
(https://www.intelligenthanddryers.com/intelligent-search)
Why is the above needed?
This will:
• Calculate the amount of uses the specified number of hand dryers will receive – key
information will be presented to you based on the specific usage in the certain type of
location such as total life span expectancy and return on investment.
• Calculate annual cost savings compared to other methods of hand drying.
See the appendix at the end of the document to show you how to accurately calculate how many
hand dryers you will require based on the amount of people using the building at any one time.

Page6
The next input section looks at the requirements of the location in more depth. It allows you to
select the characteristics of the hand dryer that are most relevant to the client’s and location’s
needs. You click on the options in the order of importance and it will give you results based on this.
If only one aspect is relevant, then you can choose just that one. You can also choose as many that
are appropriate. The search will calculate the best match as a percentage, based on the aspects
chosen and the order in which they have been placed as important.
You then click on “show me the most suitable dryers”. You will be shown dryers based on the
information provided. It gives a weighted percentage of best match. It will also give you key
information such as:
Do they need to have hand
dryers that are energy
efficient, keeping costs
down?
Do they need a hand dryer
with the quickest dry time
available?
Do they need a hand dryer that
is relatively quiet because it is to
be placed next to a meeting
room or used by small children?
Do they have specific
hygiene levels they have to
maintain?
Will the washroom be prone
to vandalism such as in a
pub or nightclub?
Is the hand dryer going to
receive heavy daily use so
needs to be able to
withstand this?

Page7
At a glance, you will then be able to scan the price point you are looking for, compare savings and
see the life expectancy in regards to the weighted percentage of best match to your chosen aspects.
For example, you may have found a 100% match to your criteria but the price point may not be
suitable or the life expectancy too low based on the usage.
Further to this you can use the filters to narrow down more and really hone in on what you need:
By filtering further, you now have all the hand dryers that:
• Best meet the required characteristics in their order of importance
• Have the right dimensions to fit in the location
• Will have the right IP rating that will comply with standards if they are to be located close to
running water
• Will comfortably cope with the usage they are expected to handle.
Please see the appendix to see; 1. How you can calculate the expected traffic usage of each hand
dryer; 2. What IP ratings are and what you should look for in a specific location; 3.What each of the
above filters is for and why you should use them.

Time is at a premium for you, so you will want to be able to get more details about the hand dryers
you have chosen fast, as well as compare models and share key information with colleagues or
embed into plans. Here is what is available to you on each product page.
Finding out more about your
perfect hand dryer(s)
Videos
We have quick reference videos available so that you can easily find the information you are looking
for, giving a more detailed description about the hand dryer and its key features. The videos also
show the hand dryer in action from different angles, so you can really get a good feel for how it will
look in your specified washrooms.
• See how the hand dryer will look on the wall
• No need to read through endless text
• Use the videos as evidence with key information and dry time testing being highlighted

Providing the evidence for your
choices
Cost calculator
This takes your information and gives cost comparisons against what is currently in the building to
dry the hands or allows you to compare if you were to put paper towels, roller towels or a
conventional energy hungry hand dryer into a new build.
You enter the following information:

Page12
This then gives you the following results:
You can then share this page as a link in an email or specification approval as evidence for the
choice.
You can find the cost calculator on each product page or use the calculator as a standalone tool,
entering different hand dryers from the same page.
https://www.intelligenthanddryers.com/cost-calculator/

Page13
Life span calculator
You can confirm that the hand dryer you have chosen, or the ones you have shortlisted, will
comfortably withstand the amount of use they will receive across the amount of hand dryers that
are to be installed.
Based on the manufacturers stated motor life it will give you the calculated number of years, in
theory, the hand dryer motor will last.
You can then share this page as a link in an email or specification approval as evidence for the
choice.

Page14
Collecting, sharing and using
information
You will now have found the perfect hand dryer(s) for your project, however you will no doubt need
to share information with others. Whether this be to embed in a specification, share with colleagues
or pass on information to your client. Here is what is available.
Building Information Modelling (BIM)
We have hand dryers that have links direct to the National BIM Library. The hand dryers that are in
the National BIM Library also have their own section for easy viewing. These can be seen here
https://www.intelligenthanddryers.com/category/bim-building-information-modelling-hand-dryers
This in turn links to RIBA Product Selector for you to easily download specs and images into plans. It
also utilises IFC and Revit.
You can also quickly view products that have National BIM Library
specifications using the category results filters in the normal way.
Creating projects
You will now have the options you want to put forward and we know it would be beneficial for you
to be able to keep them all in one place. You can collate them all together in an online project for
easy reference as well as share the information in an easy to view format. You can also add other
washroom products such as soap dispensers to the project.
How you do this is very easy as can be seen on the next page.

Page15
1. First you locate the “Save to a project, compare at a glance” located
on the right-hand side of the page
2. You will then need to create an account if you haven’t already done
so, or log into your account.
3. You will then be able to add the hand dryer to an existing
project or create a new one.
Click on the account tab at the top of the web page to access your
details and all projects created at any time.
You will then see the hand dryer (or washroom product) appear in
a project table with key information:
This project will be saved in your account for you to refer to or to add other hand dryers to the
project if you need too.
You can either print out the specs to put in a report or use the link attached to the project to share
via email.
Downloads
There are many forms of information you can download direct from the product page including but
not limited to; CAD Drawings, Manuals and Spec sheets

Other ways to search
The simple way to find a hand dryer that answers the questions highlighted in the introduction is to
use the hand dryer categories. Then filter down your options to pinpoint your perfect hand dryer.
Examples of starting categories include low (less than 100 uses a day), medium (up to 300 uses a
day) or high traffic (300+ uses a day) categories. You can also use any of the more specific categories
such as High Speed or Low Energy.
All filters can then be used individually or in combination to isolate the most suitable hand dryer(s).
Filter by size
The tool allows you to search for hand dryers in your chosen
category that have equal, smaller or larger dimensions than
your washroom installation space demands.
You can enter all 3 dimensions or, if you are only limited in one
dimension, just 1.
Essential time saving in your research, rather than having to
search through endless spec sheets.
Filter by IP
The IP rating of a hand dryer is an important consideration in
certain washrooms due to the location of water close to the
hand dryer. This becomes apparent in smaller washrooms
when locating the hand dryers close to sinks. Also in wet
rooms that contain baths or showers.
See the section below titled “What does the IP rating of a hand dryer mean?” for more in depth
information about when a specific IP rating of a hand dryer needs to be sourced.
Filter by traffic rating
You can make sure the hand dryer’s you have filtered are going
to be able to withstand the amount of use they will get. Making
sure they will give years of service when installed.
See the section below titled “How to calculate how much use
each hand dryer will receive” for more information.

Page19
Filter by category
You may have selected one key category, but is there another key aspect
you would like the particular hand dryer to have? For example, you have
chosen high speed hand dryers but you would also like them to be low
energy? Filter here to show the hand dryers that fit into both categories.
Filter by finish
You may just want to highlight
hand dryers that come in a
certain finish, as you know the
décor of the washroom needs a
particular look. This is where
you can filter these further.
Filter by max price
As with most projects, budgets are set. This filter will allow you to only
view products that do not come above your price bracket.
You now have a number of hand dryers that meet your basic requirements, leaving you safe in the
knowledge that they comply with safety regulations, have suitable dimensions and meet all the
general criteria that is needed.

Page20
How to calculate how much use
each hand dryer will receive
The most important information to collect is the amount of use each hand dryer will receive over its
lifetime. Cheaper Chinese imports may not have the motor life to last a long time in a motorway
service station, yet be more than able to withstand the use of a small office without an issue. Some
suppliers will not provide you with this information so you need to be careful. You want to be
specifying something that will give years of service.
Key information you need is:
• Number of people using the facility at any one time
• Number of daily visits likely by these people to the washroom
• Number of hand dryers that will service this usage
Then use the formula:
Examples
• Large office of 500 people
• 10 hand dryers will be required
Therefore, we would recommend medium traffic hand dryers suitable for up to 300 uses per day.
• Small office of 20 people
• 2 hand dryers will be required
Therefore, we would recommend only low traffic hand dryers would be required for up to 100 uses
per day.

Page21
How many hand dryers will I
need?
The amount of hand dryers necessary to install in a washroom depends on the expected traffic in the
washroom. It will also depend upon the type of hand dryer you would like to put into the washroom.
A conventional warm air hand dryer will have a relatively slow dry time of above 25 seconds. This is
because it relies on evaporation from the heat to dry the hands. Whereas a high-speed hand dryer
has a dry time of below 20 seconds, using air speed from a faster motor to quicken the dry time.
Using the calculations from the above section “How to calculate how much use each hand dryer will
receive” we would recommend the following:
Low traffic washrooms (under 100 uses per day)
• 1 conventional warm air hand dryer per 4 washbasins
• Or 1 high speed hand dryer for every 5 to 7 washbasins.
Medium traffic washrooms (100 to 300 uses per day)
• 1 conventional warm air hand dryers for per 2 hand washbasins
• Or 1 high speed hand dryer for every 3 or 4 washbasins.
Heavy traffic washroom (300 plus uses per day)
• 1 to 1 ratio for conventional warm air hand dryers per washbasin
• At least one high speed hand dryer per 2 washbasins

Page22
What does the IP rating of a hand
dryer mean?
In simple terms, hand dryers need to be fitted at a safe distance from water supplies and this
distance depends on the IP rating of the hand dryer.
IP is the abbreviation for Ingress Protection, and is outlined under the standard EN60529. This is an
international classification system for the sealing effectiveness of enclosures of electrical equipment
such as hand dryers, against entry of foreign bodies such
as dust, tools, fingers and moisture. The classification
will be shown using IP followed by two, or occasionally
three further numbers; these numbers represent the
level of protection the appliance provides. The higher
the number, the greater the protection.
First Number
• The level that persons are protected against contact with moving parts that could prove
hazardous
• The level of protection against solid objects entering the mechanics of the unit.
Second Number
• The level of protection against liquids entering the electrical unit
For hand dryers in a washroom, the second number is most relevant, as it indicates the degree of
protection against potentially dangerous moisture.
IP Rating What this digit relates to
First Digit
0 No special protection
1 Protection from a large part of the body such as the hand, from solid objects greater
than 50mm in diameter
2 Protection against fingers or other object not greater that 80mm in length and 12mm in
diameter
3 Protection from entry by tools, wires, etc with a diameter or thickness greater than 1mm
4 Protection from entry by solid objects with a diameter or thickness greater than 1mm

Page23
5 Protection from the amount of dust that would interfere with the operation of
equipment
6 Dust tight
Second
Digit
0 No special protection
1 Protection from dripping water
2 Protection from vertically dripping water
3 Protection from sprayed water
4 Protection from splashed water
5 Protection from water projected from a nozzle
6 Protection against heavy seas, or powerful jets of water
7 Protection against immersion
8 Protection against complete, continuous submersion
So for example, the Dyson Airblade AB14 hand dryer has an IP rating of IP35. The first number, 3,
means that the AB14 is protected from entry by tools, wires, etc. The second number, 5, indicates
that the Dyson Airblade is protected against water projected from a nozzle.
If after the IP, the first number is X, for example IPX5 it means the dryer has not been tested against
the first number classification; hand dryers are not required to.

Page24
Washroom and Bathroom Zones
Most washrooms, where hand dryers are going to
be installed, will only have sinks as a source of
water. Hand dryers are also becoming a popular
addition to the home.
Installation of a hand dryer around a sink needs to
be located at a 0.6m radius away from any tap,
which is classed as Zone 2. Hand dryers located in
Zone 2 should be a minimum of IPX4 extending to a
minimum of IPX5 if the equipment is exposed to
cleaning jets.
“Outside of Zone 2 the general rules of the Standard
apply, but in reality virtually any equipment can
now be installed outside Zone 2." (Locke, D (2008);
Guide to the Wiring Regulations: 17th Edition IEE
Wiring Regulations (BS 7671: 2008; p226; Wiley)
Therefore, any hand dryer can be located outside of Zone 2 for a sink, as long as it complies with the
following standards regarding bathrooms with baths or showers.
Washrooms with Baths and Showers
There will be instances where showers and baths can be present such as changing rooms in leisure
centres. The 17th Edition of the IEE Wiring Regulations now considers a room containing a bath or
shower to be a special location due to the increased risk of electric shock.
"The zones provide a means of controlling the location type and environmental rating of electrical
equipment installed in a bathroom. They are only a guide and, regardless of this, the installation
must be properly designed to take into account all foreseen risks in the design of a bathroom within a
particular building." (Locke, D (2008); Guide to the Wiring Regulations: 17th
Edition IEE Wiring
Regulations (BS 7671: 2008; p222; Wiley)
The bathroom has been split into Zones 0, 1 and 2.

Page25
• Zone 0 is inside the bath or shower itself. Equipment in Zone 0 should be a minimum of IPX7, which
means it has protection against immersion. In Zone 0, no switchgear or accessories are allowed
and only a 12V current-using equipment complying with a relevant Standard is allowed.
• Zone 1 can be considered to be the area above the bath or the area where shower water is likely to
be directly sprayed. This area is above the bath, 2.25m from the floor. Equipment in Zone 1 should
be a minimum of IPX4, extending to a minimum of IPX5 if the equipment is exposed to cleaning
jets. In Zone 1 only 12V Separated extra low voltage (SELV) switchgear or accessories allowed.
• Zone 2 is the area beyond Zone 1, extending by a further 0.6m, to a height of 2.25m from the floor.
Equipment in Zone 2 should be a minimum of IPX4 extending to a minimum of IPX5 if the equipment
is exposed to cleaning jets.
"There are only regulations for Zones 1 and 2. Outside of Zone 2 the general rules of the Standard
apply, but in reality virtually any equipment can now be installed outside Zone 2." (Locke, D (2008);
Guide to the Wiring Regulations: 17th Edition IEE Wiring Regulations (BS 7671: 2008; p226; Wiley)
