Cannabis greenhouse farm closed by local government, and we took back the lightly used like new greenhouse exhaust fans. No original cardboard packaging. We are selling them at discounted price. We offer volume discount. \u003c\/p\u003e\n\u003cp\u003eThe exhaust fans has two types of shutter opening mechanisms when the fan start running-push type and heavy hammer type. The push type fans use mechanical push arm to open the front shutter, this type has more stronger shutter opening force and good for areas with strong wind. The heavy hammer type fans use a slightly weaker weight and centrifugal force to open the shutter. Push type is overall built more heavy and solid. \u003c\/p\u003e\n\u003cp\u003eSpecifications of the fans we carry.\u003c\/p\u003e\n\u003ctable width=\"100%\" style=\"width: 100%; height: 171px;\"\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 19px;\"\u003e\n\u003ctd style=\"width: 6.968641%;

I was ripped off by both Fedex and UPS multiple times for using them to ship 40 inch exhaust fans. Fans need to be picked up locally, or be LTL freight shipped on pallet, freight shipping 1 to 10 fans shipping price are not very much different, roughly ranging from $500 to $1000, so the more fans you buy, per fan shipping cost is lesser. Please minimum buy 2 fans, when you buy one fan, the freight shipping charge is not enough to cover freight shipping cost.\u003c\/p\u003e\n\u003cp\u003eIf you are local and can pick up, that will be great.

Recommended exhaust fan size is minimum 33,000 cfm., 2 40 inch exhaust fan's combined CFM is 36000 cfm, so 2 40 inch exhaust fans are sufficient for a 30'x100'x11' greenhouse. It is beneficial to the plant with slightly higher CFM, some growers use 3 fans, two at lower bottom, one in center top. \u003c\/p\u003e\n\u003cp\u003eWe also carry replacement exhaust fan motors and belts with discounted price.
