Reduce heat stress and improve air quality with Schaefer's uniquely designed circulation fans. Unrivaled in the market, these greenhouse fans are engineered to produce greater air movement and superior cooling no matter the application. You don't hear them. You don't see them. You only feel them!

Also known as Horizontal Air Flow (HAF) fans, these ceiling-mount fans move air in a coherent horizontal pattern, creating the gentle "racetrack" airflow pattern needed in greenhouses to maximize heat distribution and humidity control by mixing the air from ceiling to floor. You also can use them in garages, mechanic shops, warehouses, factories and anywhere else you need a heavy-duty circulation fan. They operate off standard 115-volt power using an integrated five-foot cord.

Each Schafer HAF fan is made in the U.S. with a two-year warranty. Greenhouse Megastore has them in several sizes that can move anywhere from 450 CFM (Cubic Feet per Minute) to 10,000 CFM of air - see below for the specifications of each. Our bulk discount pricing lets commercial and industrial growers get the fan circulation they need while staying within their budget.

Schaefer HAF Greenhouse Fan Features:

  • Deep guard design for unmatched performance, low noise levels and safety without sacrificing airflow.
  • Matched high-quality motors and blades for maximum efficiency.
  • Powder-coated steel guards for increased durability and corrosion resistance.
  • Powder-coated steel mounting bracket and power cord included.
  • Wide variety of mounting options available for flexible and easy installation.
  • Two-year manufacturer's warranty
  • Made in the U.S.
  • NOTE: Models without OSHA guards should be mounted seven feet or higher.

Great fans at a good price and delivered in a reasonable time frame.

This Fan Is Well Made And Last Just Like A Bunny.

I created a greenhouse out of PVC pipe. (23' x 12') The fan was used continuously for about three years until a Tree came down on my greenhouse and destroyed it. That was about 8 to 10 years ago. The fan spend some time in the elements' for longer than I would like to mention or at least until I unhooked it and took it into my house in which it stayed upstairs in the heat for a few short years. Now, I am building a new greenhouse and today 5-28-2023 I installed the same fan. Plugged it in and it still works after all that abuse. This is really a very nice fan for the size it kicks out some air.

The price is worth every single penny. It is so nice to see that people still build great products, its metal not cheap plastic.
