4" Inch Axial Inline Duct Fan 70 CFM 110V

Our axial inline fan is perfect for small mushroom tents like our "martha" style four tier mushroom greenhouse. This fan can be used to circulate fresh air and control humidity in your mushroom grow area.

The durable built-in copper motor features thermal protection and is housed by a galvanized aluminum alloy casing to resist atmospheric corrosion from humidity. The motor contains a permanently lubricated ball bearing that operates quietly and does not require any maintenance. The built in mounting brackets make it extremely easy to install on to the top shelf of your martha-style grow tent. The fan can run continuously without maintenance. Fan comes complete with a three-foot power cord and a US-style 110v plug.
