Easy install.

Ordered the P1216 Fan System for my 10x12 greenhouse, and it has been the perfect match. The 3-speed fan offers options for the correct amount of air movement depending on the weather conditions, and the electric opener for the intake vent ensures the vent stays closed until it is needed for ventilation. Also ordered the 12" and 16" hoods for the fan and intake vent to keep the winter storms out.

   

Works well at bringing the temp down in my 13x13 grow more greenhouse. It's not a drastic drop, but does bring it down by at least 10° and keeps air circulating.

Products arrived timely to Alaska. Install was straight forward and directions where easy to understand. So far, it has functioned as it should and I'm really pleased with it. It was installed in a 12x24, double-wall polycarbonate greenhouse.

Recently I installed an ACF Premium Plug-In Exhaust Fan System P1620 in a greenhouse. Product came promptly. The plug-in system assembled as designed. The weather here is not hot yet & the size of system is fine. I could venture to say I may be adding a 2nd system for hotter weather to move more air.

One challenge I'm having is with the fan shutter as it is not intentionally controlled. It's held open when the fan runs, otherwise it flaps and flaps from the wind.

I'm told in the the colder season these shutters are going to have to stay shut. Initially, I may try & create some type of return spring that will pull the shutter shut but the fan can still blow open.

A more positive control option here would be to add a damper motor for shutter control as is installed on the intake shutters. It could be plugged into the power strip also.
