Fans

Fans help establish the perfect climate in your grow room and supply your plants with fresh air and thus prevent mold and illness.

Air Intake Fans

Air Intake Fans

Air intake fans only have to be pushed into a tube and are ideal regarding their efficiency and power consumption. They produce very little sound while running.

Extractor Fans

Extractor Fans

These extractor fans are very efficient and economic. They also run relatively quiet.

Noise Insulated Fans

Noise Insulated Fans

Noise Insulated fans help in reducing the noise output of a powerful air extraction system. They are especially useful together with other noise reducing accessoires like acoustic ducting.

Centrifugal Fans

Centrifugal Fans

Snail-shell centrifugal fans certainly are not the most inexpensive but they are extremely quiet. An advantage you might appreciate.

Circulation Fans

Circulation Fans

Circulation fans distribute incoming fresh air, ensure steady growth of the plants and help circulate the air in the grow room.

Can-Fan

Can-Fan

Can-Fan is a manufacturer of high quality ventilation accessories for home growers. In addition to the inline fans, which are produced in Germany by the renowned company Ruck for Can-Fan, their range also includes activated charcoal filters and

How to calculate the necessary fan capacity for a room

((room volume in m³) + (30% of the room volume since the filter might reduce the performance ) ) * desired air exchange frequency.

If we assume a room size of 20m³ and we want to exchange the air 12 times per hour we get the following result:
(20 + 20/100 * 30) * 12 = 312m³
Thus, we need a fan that has at least the power to achieve the air flow of 312m³ per hour. Yet, this calculation applies only to duct hoses less than 1m long. If they are longer, you need to take the length into account also. So for let's say 3m long hoses you calculate:
( (20 + 20/100 * 30) + 3) * 12 = 348m³
You'll need a fan with a power of approx. 350m³ per hour.

Fitting Sizes of fans and filters

The connecting sizes for the parts are standardized. Depending on the fan capacity they usually range from 100mm to 315mm. If you already have a fan or filter and the other part does not fit you can get a reducer.

Intake Fans

If the grow room only requires fresh air for a higher oxygen amount, simple intake fans should suffice. Just put one into your duct hose.

Air Flow Control

For your environment control (duration of fan operation and power) you can use either simple timers or special fan controllers that can regulate the temperature or air humidity.
