Extraction Rate

The Vent-Axia Silent Fan VASF100T exhibits two different extraction rates depending on the speed setting selected. It can extract 73 cubic meters per hour (15 litres per second) when on high speed and 54 cubic meters per hour (21 litres per second) when on low speed. This feature comes in handy when you want to remove humidity build-up in your bathroom.

The great thing about having two extraction rates means you can adjust it for your application. You can opt for the lower extraction rate setting if you are installing in your toilet or opt for the higher extraction rate setting if you are installing in your bathroom.

Power Consumption

Like the extraction rate, the Vent-Axia Silent Fan also consumes power differently, depending on the speed at which it is running. For instance, when you want humidity driven out of your bathroom at high speed, you run the fan at high speed, which means it will use more power and, in this case, it will use 4.8 watts.

The same case applies when running it at low speed. It uses significantly less power, amounting to 2.7 watts. 

Noise Level

Integrated ultra-low sound technology ensures a maximum reduction in noise level. The VASF100T is one of the quietest extractors currently in the market, producing 26 dB (A) when on high speed and very low 14 dB (A) when on low speed.

As a result, it provides maximum ventilation with almost no noise in your bathroom, without a change in quality, providing other people with a relaxed environment with no-noise disturbance.
