Exhaust-Fan Kit 500 m³/h - 160mm Le Filtre

Exhaust air is an important matter of indoor growing. This set provides you with well adjusted devices.
The active carbonate filter by LeFiltre only weights about 1 kg, much less than other conventional filters.
This filter also stands out due to its stableness.

This set includes following articles:

• 1 - Le Filtre active carbonate filter 500m³/h filters reliably each kind of odours
• 1 - LIT ventilator 160mm - 420m³/h gentle and of good repute
• 2m - flexible duct hose 160mm, 2 meters on a roll, no insulation for noise reduction
• 3x - ductl-hose clamps to connect pipe with fan and carbonate filter
• power cord 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=18.75m³)
2. Allowance for the activated carbon filter
Add approx. 35% to the room volume since the carbon filter reduces the power (18.75m² 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= 2m²
4. Determine the exhaust volume
In a room we need an air exchange of minimum 12 x the room volume per hour. In grow cabinets approx. 30 x. 12x(18.75 + 2 + 6,56) = 327 m³
