If you aren't sure what size fan or shutters you need, use our Fan & Shutter CFM Calculator.
| Our exhaust fans are ideal for cooling and providing fresh air inside a greenhouse. Simply add intake shutters and any of our greenhouse controls, and you will have all you need to equip your greenhouse with a durable fully automated ventilation system.

Variable Speed Louvered Exhaust Fan
Features:- Rustproof aluminum shutter frame with built-in interlocking louvers to reduce heat loss in the greenhouse during cold months. - Fans come equipped with completely enclosed variable speed direct drive motors which can be adjusted from 100% to ~30% of CFM if one of our optional fan speed controls is added. This allows you to reduce fan speed during cold months minimizing cold air shock to plants. Fans only run at maximum speed without a speed control. - Fan motors come prewired with a grounded 9' power cord. - Fans can be automated with any of our 110/120 volt greenhouse thermostats. - Fans come with plug but can be hard wired as well. |

System Wiring Kit Instructions |

These
complete wiring kits are designed for wiring our variable speed
fan systems in greenhouses or other wet areas. Kits use all
rustproof materials which meet or exceed building code
requirements for wet locations when properly installed, and the
flexible conduit makes installation quick and easy. Wiring kit
can be wired directly into an existing electrical line or wired
to a power supply cord (included with our fan system packages)
and plugged into an outlet. Fan wiring kits include: flexible
conduit, flex & T connectors, aluminum conduit clamps, 14 gauge
wire & wiring nuts, and installation instructions. Additional
accessories for these wiring kits are available in our
Greenhouse Electrical section. The 25' wiring kit is designed for small greenhouses using a single intake shutter fan system. The 50' and 100' kits will work with single or two shutter fan systems and larger greenhouses.

Screened Venting & Cooling in 1 Package Evaporative air coolers, also called pad or swamp coolers, have proven to be the most effective cooling system for a greenhouse short of an air conditioner. It pumps water over the special cooling pads which lowers the temperature of air passing through them. A powerful blower pulls air through these pads and pushes the cooled air into the greenhouse. Hot air can be exhausted through roof vents or exhaust shutters and automated with one of our prewired or plug-in thermostats. The cooling pads also act as a filter and help keep out unwanted insects, dust, and pollen. Coolers have a 2 speed fan which can be used for ventilation with or without wetting the pads. Coolers come with water hose connection kit for constant water supply. Requires a standard 110/120 volt outlet. |
