Exhaust - Fan Kit 355 m³/h - 125mm

Exhaust and odor control play a vital role in indoor growing. For the first steps, this kit is the right tool. Comes with:

• Activated carbon filter 125mm - 400m³/h, filters all kinds of odor from the exhaust.
• This filter is equipped with top-quality and long-lasting CTC 70 Activated Charbon which works effectively in growing spaces with an air humidity of up to 85%. The cheap alternatives with CTC 55 carbon often are unsuited for îndoor growing and can't guarantee effective deodorization.
• LTI Fan 125mm - 355m³/h, reliable and very quiet.
• Flexible plastic duct hose diam. 127mm, 2 meters on a roll, no insulation for noise reduction.
• 2x duct hose clamps to connect the hoses with fan and filter.
• Mains connection 2m

What size do I need?

1. Dimensions
Height x Width x Depth of the room (e.g. 2.5m x 3 m x 2.5m=18.75m²)
2. Allowance for the activated carbon filter
Add approx. 35% to the room volume since the carbon filter reduces the power (18.75m³ x 0.35=6,56)
3. Allowance for the duct hose
Per meter duct hose add approx. 1m² -> in our kit 2 meters - 2 x 1= 2 m²
4. Determine the exhaust volume
In a room we need an air exchange of minimum 12 x room volume per hour. In grow cabinets approx. 30 x. 12x(18.75 + 2 + 6,56) = 327 m³
