Exhaust - Fan Packet 1,020 m³/h - 250mm

Exhaust and odor control play a vital role in indoor growing. This set the basics for a good start.

The packet comes with:

• 1 - Activated Carbon Filter 250mm - 1,200m³/h, filters reliably all kinds of odors from the exhaust air.
• 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.
• 1 - LTI Fan 250mm - 1,020m³/h, reliably and quiet.
• Flexible plastic duct hose diam. 125mm, 2 meters on a roll, no insulation for noise reduction.
• 2x duct hose clamps to connect the hoses with fan and filter.
• cord 2m

How to find the right Fan

1. Determine the room size
Height x width x depth of the room (e.g. 2.5m x 3 m x 2.5m=6,56)
2. Compensation for the carbon filter
Add approx. 35% to the room volume to compensate for the carbon filter which reduces the effect (18.75m² x 0.35=6,56)
3. Compensation for the duct hose
One meter hose corresponds to approx. 1m² -> e.g. the duct hose from our packet - 2 x 1= 2m²
4. Calculation of the intake volume
All the air in a room should be completely changed 12 times per hour (room volume multiplied with 12). For boxes multiply with 30 due to the higher temperatures. 12x(18.75 + 2 + 6,56) = 327 m³
