This ES Series Fan is a commercial-quality exhaust fan for the hobby grower. It has a heavy-duty design made of metal - no plastic parts! The fully enclosed motor is thermally protected and designed for continuous duty. Each commercial fan includes an exterior aluminum shutter that opens fully for maximum CFM output. Outdoor air is drawn in through a motorized shutter and hot air is exhausted through this motorized shutter fan. An optional 10-foot grounded cord is available for each model. These industrial fans keep fresh air flowing through a greenhouse, which controls temperatures, lowers the humidity and reduce the risk of fungal distance. You can also use it as a garage exhaust fan. We offer commercial shutter fans in size from 10 to 30 inches with motors ranging from 1/10 to 1/2 HP - see the tables below for their CFM ratings, power requirements, speed options and more. They’re covered by a full two-year motor warranty and our 100% customer satisfaction guarantee.

Additional Information Manual Commercial Shutter Fan - ES SHUTTER FANNote: The wiring diagram for the shutter fan is located directly on the motor housing. Thermostat How-to-Wire for Heating or Cooling How Do I Size My Fans and Shutters System? 1. The first thing that you need to determine is the amount of air required. This is stated in CFM (Cubic Feet of Air per Minute). 2. Use the following formula to determine the CFM required for your greenhouse:CFM = Length x Width x HeightExample: A greenhouse 12' wide x 24' long x 12' high requires 3,456 CFM (12 x 24 x 12 = 3,456)) 3. Reference the above table. Select the appropriate combination of fan(s) to achieve the necessary CFM rating. Be sure to match the total CFM output for your exhaust fan(s) to the CFM ratings for your Inlet Shutters.
