How To Size Fan & Shutters System?

  1. First thing is to determine is the amount of air required. This is stated in CFM (Cubic Feet of Air per Minute). In addition, the required Air Changes Per Hour (ACH).  A Greenhouse requires 60-120 ACH's depending on location and weather conditions. 
  2. The following formula to determine the CFM's and ACH's required for your greenhouse:
    CFM = Width x Length x Height 
    Example: Greenhouse 12' wide X 40' long X 12' High requires 9,600 CFM at 60 ACH, 14,400 CFM at 90 ACH and 19,200 CFM at 120 ACH. 
  3. Review the above table. Select the appropriate combination of fan(s) to achieve the necessary CFM rating and ACH. Be sure to match the total CFM output for your exhaust fan(s) to the CFM ratings for your Inlet Shutters. Below are examples of end wall to end wall and side wall to side wall ventilation.

    Best Grow | Push fans moves air over the plants | Cannabis Cultivation

    Posted by Greenhouse Manager on 7th Feb 2021

    We were referred to Factory Fans Direct by another grower. During our first call we were impressed by Mike knowledge, recommended design and equipment for our facilities. With his guidance we selected the JD Light Traps Exhaust Fans, Power Intakes with Light Traps, Cooling wall and Green Breeze HAF Fans and controllers. The design worked perfectly and we had the best grow of my career. Highly recommend Factory Fans Direct!!
