Dryflow Viper Hand Dryer DFVP02 (brushed satin)

DFVP02

Applications: Cinema/Theatre, College, Gym, Hotel, Medium use (101 to 300 uses per day), Office, Public Attractions, Public Toilet, Pubs, Restaurant, Retail Outlet, Senior school (key stage 3), Sports Stadium, University

The Viper utilises the latest in modern blade technology. Two angled blades of air simultaneously scrape moisture from the hands providing a rapid and consistent dry which is not so easy to achieve from a single outlet.  With 4 settings to choose from, you can really customise this hand dryer based on your own unique requirements.  This fast drying, yet quiet hand dryer can be set to a really energy efficient 600-800W by switching off its heater element, saving you money and reducing energy usage.  These are proving popular with restaurants, shopping centres and offices due to their robust build and quiet in operation noise levels.  The expected motor life means we would recommend this unit is suitable for up to 300 uses a day and it comes with a 3-year guarantee – extended over similar units under different brand names.

The HEPA filter that comes as standard cleans the air pulled into the unit, therefore making sure that the air blown over the hands is dirt and microbe free.  The setting buttons are hidden away under the filter griddle, making sure they cannot be tampered with unnecessarily.  These settings allow you to reduce the already quiet noise level further should this be required.  They also allow for heat activation when a cold environment requires it, but also this can be disabled in warmer washrooms to keep energy costs low.  Modern high speed hand dryers use the speed of the airflow to dry the hands and the heat is there purely for comfort.  Two separate sensors are installed, making sure of instant activation no matter which hand is placed under the unit first.

The Dryflow Viper has been awarded the Quiet Mark. This means it is one of the quietest on the market, in its category.

This quality made, vandal resistant hand dryer provides quick dry times due to its ability to place 2 powerfully focused airflows on each individual hand simultaneously.  For a high-speed hand dryer, this remains relatively quiet and the ability to reduce the energy consumption at the flick of a switch is a real bonus.

Technical Description

Heavy duty 304 stainless steel cover with robust construction. Adjustable universal brushed motor produces a maximum of 201MPH of bladed air through 2 angled outlets. The heater element consumes 1.2kW giving a minimum total output of 600 - 800kW and a maximum of 2kw dependent upon which of the 4 settings is chosen. Setting buttons are hidden to avoid unwanted tampering. The sound level is between 70 – 74.5db at 1m - has been awarded the Quiet Mark.  HEPA filter included for clean purified airflow.

Performance Rating

  • Energy Consumption

    This rating is based on the watts per dry of the hand dryer which is derived from the rated power and the time taken to dry the hands. We have used the figures based on either the manufacturer’s dry time, if yet to be in house tested or based on the in house testing dry time we have conducted. This will also be based on the most energy efficient setting, if the hand dryer is adjustable for speed and/or heat.

    Watts per dry:

    • 0 – 1.99W = star rating 5
    • 2 – 2.99W = star rating 4.5
    • 3 – 3.99W = star rating 4
    • 4 – 4.99W = star rating 3.5
    • 5 – 5.99W = star rating 3
    • 6 – 6.99W = star rating 2.5
    • 7 – 7.99W = star rating 2
    • 8 – 8.99W = star rating 1.5
    • 9 – 9.99W = star rating 1
    • 10W and above = star rating 0.5
    3.0 out of 5
  • Quiet Sound Level

    This rating is based on the manufacturers stated sound level, usually at 1m. Please see the section titled "how quiet is the." for more information and independent test results, which give a more accurate noise decibel level. These ratings will also be based on the low noise setting, if the hand dryer is adjustable for speed. Therefore at full speed the hand dryer may not be quiet, however it may be adjustable to become quiet if this is required.

    Decibels (dB):

    • Up to 68dB = star rating 5
    • 69 – 70dB = star rating 4.5
    • 71 – 72dB = star rating 4
    • 73 – 74dB = star rating 3.5
    • 75 – 76dB = star rating 3
    • 77 – 78dB = star rating 2.5
    • 79 – 80dB = star rating 2
    • 81 – 82dB = star rating 1.5
    • 83 – 84dB = star rating 1
    3.5 out of 5
  • Life Expectancy

    This rating is based on the number of motor life cycles (number of uses) the hand dryer, in theory, will last for. This is based on the motor life expectancy given to us in hours, from the manufacturer.

    The number of cycles (uses) has been calculated as follows:

    (Number of seconds in the hour / seconds per dry) x motor life hours

    For a more individualised longevity calculation based on your own usage numbers please use the life expectancy calculator on each product page.

    Number of motor life cycles:

    • 1,000,000 and over = star rating 5
    • 800,000 – 999,999 = star rating 4.5
    • 600,000 – 799,999 = star rating 4
    • 400,000 – 599,999 = star rating 3.5
    • 200,000 – 399,999 = star rating 3
    • 100,000 – 199,999 = star rating 2.5
    • 80,000 – 99,999 = star rating 2
    • 60,000 – 79,999 = star rating 1.5
    • 40,000 – 59,999 = star rating 1
    • 39,999 and under = star rating 0.5
    3.0 out of 5
  • High Speed

    These ratings are based on the in house testing we have conducted regarding dry times. They show realistic comparisons of what to expect from each hand dryer. Please note that the manufacturer stated dry time is not always accurate when compared to the hand dryer being used in realistic conditions. The ratings are based on the hand dryer being placed at its high speed setting if it can be manually adjusted.

    Dry Speed (seconds):

    • 10 – 11 seconds = star rating 5
    • 12 – 13 seconds = star rating 4.5
    • 14 – 15 seconds = star rating 4
    • 16 – 17 seconds = star rating 3.5
    • 18 – 19 seconds = star rating 3
    • 20 – 21 seconds = star rating 2.5
    • 22 – 23 seconds = star rating 2
    • 24 – 25 seconds = star rating 1.5
    • 26 – 27 seconds = star rating 1
    • Over 28 seconds = star rating 0.5
    4.0 out of 5
  • Vandal Resistance

    Some hand dryers would not be suitable for some locations where abuse may be likely such as a train station or night club. However the same hand dryer would be suitable for an office or school location. These ratings are based on an added together scoring system where the higher the rating, the more suitable we would recommend for areas where abuse may be likely.

    Vandal Resistance score

    • Compact size = score 0.5              
    • Decreased blockage potential = score 0.5
    • Additional Backplate/ fixings strength = score 1
    • Anti-vandal extras = score 1
    • Metal / ABS = score 1    
    • Cover thickness 1.5mm or more = score 0.5        
    • No leverage points (design) = score 0.5

What extra hygiene aspects does the Dryflow Viper have?

Washing hands correctly is the best way to ensure high levels of hand hygiene.  Making sure hands are completely dry is the next important aspect of hand hygiene.

Most modern hand dryers have standard hygienic properties such as fast dry times and touch free sensors to activate. However for added peace of mind some models have enhanced hygienic properties.

The extra hygiene aspects this hand dryer has are:

  • HEPA Filter.
  • Dry times below 15 seconds
  • Touch free activation sensor

What is the life expectancy of the Dryflow Viper?

So how long will this dryer last?

Hand dryers can have 2 types of motor which are:

  • A digital brushless motor
  • A universal brush motor

In theory, universal brush motors do not last as long as digital brushless motors and require the brushes to be changed periodically.  They also vary in their lifespan.  Digital motors however do cost more to repair should they fail at any point.  There are variations in the lifespans of both universal brushed motors and digital motors.

The best way to choose what is right for you is to look at your facility and the amount of use each hand dryer is expected to get.  This way it can be determined if a brushed motor hand dryer would be most suitable for you or whether investing in a digital brushless motor would be more cost effective.

How vandal resistant is the Dryflow Viper?

Depending upon the location, hand dryers can be damaged through vandalism. This includes being leveraged off the wall, damaging the outer casing and putting foreign objects into the openings. Locations this is likely to occur include pubs, nightclubs, transport facilities such as train stations, schools, stadiums, arenas and unattended public toilets to name a few.

The Dryflow Viper hand dryer has the following features to help reduce vandalism:

  • Small compact size
  • Limited outlets for foreign objects to be placed in to cause blockages
  • A thick (1.5mm) steel cover
  • Smooth shape, not allowing for leverage to pull off the wall

The Dryflow Viper's design make this a very robust and resilient hand dryer, suitable for all locations where vandalism may be possible.

How suitable is the Dryflow Viper for disabled users?

There are a few points to consider when choosing a hand dryer with disabled users in mind.  These include:

  • Wheelchair access with regard to users being able to position their hands correctly
  • The amount of moisture that will be left on the floor after drying if units are to be used by people physically impaired
  • The noise level of some high speed hand dryers may be too loud for some users, such as users with autism, multiple sclerosis etc.

Disabled areas often double up as baby changing facilities, so considerations include leaving extra space for double buggies, noise levels for children etc.

The Dryflow Viper hand dryer has the following features that may negate these concerns:

  • Quiet in operation
  • The blades of air direct water away from the user
  • “Hands under” type unit creating more accessibility and wider range of hand positions

How quiet is the Dryflow Viper?

Manufacturer s typically measure sound levels in terms of decibels dB(A) @ a 1 metre distance in a sound proof chamber. This measurement does not take into account the increase in noise when hands are positioned under/in the dryer or when the sound bounces off walls. Where possible we supply manufacturer's stated dB (A), and 2 independent tests which are more reflective of 'real conditions’.

The Dryflow Viper has been awarded the Quiet Mark. For more information view www.quietmark.com .  This means it is one of the quietest on the market, in its category.

Manufacturer stated

70 - 74dB(A)

Hands under in an anechoic chamber (sound proof)

N/A dB(A)

Hands under in a normal room*

N/A dB(A)

*represents maximum “real life” volume

Equivalent Examples:
Normal Conversation                      50 - 70dB(A)
Vacuum Cleaner                             70dB(A)
Busy Traffic / Alarm clock               80dB(A)
Lawn Mower / Chainsaw                 90dB(A)
*various internet sources

Please click here to read our guide to help understand what the perceived decibel level above would be equivalent to.

It is worth noting that if your noise concern relates to the noise carrying into different areas of the building then pitch will be just as relevant as sound output (loudness). Higher frequency pitches will not travel through walls as easily as low frequency pitches for example.

We are passionate about helping others reduce carbon emissions, which in turn will help slow down the negative effects of global warming.  For more information about carbon emissions and the environment click here

The following table shows the approximate amount of carbon emissions produced to complete 1000 dries:

Dryflow Viper

1.80 Kg/CO2 per 1000 dries

Paper Towels*

22.5 Kg/CO2 per 1000 dries

Standard warm air hand dryer+

13.5 Kg/CO2 per 1000 dries

*Based on using 3 towels per dry
+Standard warm air hand dryer use approx 25 watts per dry
