Boxed extractor fan

Our standard box is made of thick MDF panels and is equipped with top of the range S&P/Nicotra and Torin extractors. These ventilators are well known in the proffessional horticulture scene and are one of the most powerful of their kind. Due to the perfect alignment of these motors you are guaranteed very low noise levels, and an optimal result.
A simple equation to find out how much air extraction you will need is: HALF THE TOTAL WATTS OF THE LAMPS  + 20%.
 
So for instance a room with 4 x 600W lamps:
600 x 4 = 2400
1/2  = 1200
+20% = 1440

This room will need an extractor fan and carbon filter with a capacity of atleast 1440m3. Always round up so a 1500m3 extractor + a 1400m3 carbon filter is perfect.
