Dryflow Viper

The Viper has been available on the UK market for 4 years now and is often positioned as an affordable alternative to the Dyson V, utilising a similar, angled dual-blade airflow technology. It is available in a brushed steel or white version. 

So how well does it stack up against leading brands?

£229 + VAT


The Dryflow Viper - Value

At £229 + vat this is firmly a mid-priced dryer and it does represent decent value. It is less than half the price of the Dyson V and you are still getting fast, energy efficient, HEPA filtered air to dry your hands.


The Dryflow Viper - Dry speed

The viper doesn’t make it to the top table for dry speed but never the less, achieving 15 seconds in our stringent tests is a very good result. This makes it only 3 seconds slower than the Dyson V and faster than the majority of high-speed units on the market today.

The Dryflow Viper - Energy efficiency

The energy-efficiency of a dryer depends on 2 things, rated power to produce a given dry speed. 

The Viper has a rated power range between 0.6kw on unheated eco speed mode, and 2kw on full speed, heated airflow mode. It has a per dry consumption range between 2.5 - 8.3 watt/hours. 

The Viper is at its most efficient when using unheated airflow and max speed. So, essentially this dryer is capable of being one of the most efficient products on the market but also being at the high end of consumption for a modern dryer, hence the score of 3. Set it up right and efficiency could move to a 4.5/5 score. 

At its most efficient 1000 dries could cost as little as 30p and a 98% saving against paper towels.

The Dryflow Viper - Quiet operation

The manufacturer states this dryer is 70 dB(A) on eco mode and 74 dB(A) on maximum speed and we found this range to be accurate.

The Dryflow Viper - Vandal resistance

A heavy-duty bit of kit, definitely suitable for harsher locations.

The Dryflow Viper - Life expectancy

The motor life is 1500 hours and this would be expected to deliver 360,000 hours. That makes the dryers suitable for locations in the Mid (100-300 uses) a day range. I would recommend this more for areas at the lower end of that scale to achieve a really satisfactory lifespan. It's backed by a 3 year warranty.

The Dryflow viper and the environment

We have been working with the manufacturer to eliminate polystyrene in packaging and our latest deliveries are now coming in with zero plastic packaging. The carbon footprint of the product is approximately 33.6 kg/co2

The Dryflow Viper - Conclusion

The Viper is a decent alternative to the Dyson V. It’s a solid bit of kit. As long as you don’t fit them in a mega busy location, it will give many years of service. 

Overall, it’s pretty fast (15 secs), energy efficient on eco-settings, and has the flexibility to reduce noise down from an already tolerable level. The only negative is that when the heat switch is turned on, it is a little energy hungry by modern standards. It could benefit from a more efficient heater element. 

A great mid-priced dryer for schools, pubs, places where a bit of mis-use and abuse may occur.
