2287 Sadiq ’22 Exhaust Fan End Wall Removed
Removing the structure alone does present a little bit of a challenge and a little stress but this was part of the design features. While the end wall detaches the ridge pipe is attached in a fix location so it cannot fall on the plant. By removing the side pipes the end wall can be cleared from the plant. During the design and development stages of the cold frame this modification was made to help reduce the chance of plant damage.
Selecting the correct size vent and fan is important for the larger and also this smaller structure. It can come down to CFM (Cubic Feet per Minute) with a few considerations to take into account. For this purpose, a 24” shutter vent and a 16” fan were selected. The fan had three speeds, but needed to only be run on the slowest speed as everything seemed to be calculated to work out well.
