Fans & Blowers

Fresh air is essential for healthy plant growth, especially in an indoor environment. Intake and exhaust fans are necessary to exchange air in the garden area, as well as to provide relief from excess heat and/or humidity. Circulation fans are also necessary to strengthen plant stems and to prevent stagnant air from building up around leaves. Fan capacity is expressed in CFM (cubic feet per minute) of air movement. To exchange air effectively, it should be done in 5 minutes or less. To choose the right fan(s) for your space, multiply the garden area's length x width x height. Divide this cubic volume by 5 to determine the MINIMUM CFM of air movement. In other words, your fan should be able to remove or exchange the entire volume of air in your garden area in 5 minutes or less.

Fans are available in three main styles: Axial Fans, Squirrel Cage Blowers, and Inline Centrifugal Fans.

Axial Fans

Axial fans (like the vent fans used in bathrooms) are good for moving air through a wall or ceiling, but are not efficient for moving air through tubing or ductwork. Fan cords are also available.

  • 100 CFM Axial Fan  $32.99
  • 240 CFM Axial Fan  $74.99
  • 560 CFM Axial Fan  $99.99
  • Fan Cord for Axial Fan $2.99
  • Fan Guard for Axial Fan $0.99
Blowers

Also called "squirrel cage" or "shaded pole" blowers, these fans create enough torque to move air effectively through duct tubing. Blowers can be used as intake or exhaust fans, and are often used with air-cooled lighting systems. The 465 CFM blower is not recommended for use with duct installations but to its motor cooling openings, but it works great as an intake or exhaust fan moving air directly into or out of a space. Blower flanges, adapters and duct tubing are featured separately below.

AHL carries ActiveAir blowers from Hydrofarm (except 495 CFM), which feature heavy-duty construction, grounded power cord, and built-in tubing flange on the inflow side. One year limited warranty.

  • 95 CFM Blower  $69.99
  • 180 CFM Blower  $79.99
  • 265 CFM Blower  $99.99
  • 465 CFM Blower  $119.99
  • 495 CFM Dayton Blower (Does not include intake or exhaust flanges. Order '4" Tubing Adapter for 265 CFM blower', below, in addition as needed).  $169.99
Inline Centrifugal Fans

Inline Centrifugal Fans, also called "tube fans" and "duct fans," are excellent for moving air through long lengths of duct tubing. Ideal for multiple air cooled light systems, and a must for use with Can-Filter and Phat Filter activated carbon air filtration systems. The CFM rating is for free air movement with no resistance; actual CFM capacity will vary due to duct lengths and other factors.

The 4", 6", and 8" fans are the Vortex brand, the 10"and 12" fans are the Eco-Plus brand.

All Inline Centrifugal Fans are very durable and have a five year warranty.

  • 4" Vortex Inline Fan, 175 CFM  $149.99
  • 6" Vortex High-Output Inline Fan, 452 CFM   $209.99
  • 8" Vortex High-Output Inline Fan, 747 CFM   $254.99
  • 10" Eco-Plus High-Output Inline, 781 CFM   $289.99
  • 12" Eco-Plus High-Output Inline, 984 CFM   $349.99
  • Speed Controller for Inline Fan, $34.99
Circulation Fans

These 3-speed oscillating and circulation fans from AirKing are very powerful and will circulate air in a garden area. One year warranty. 

  • Oscillating Fan 16" Wallmount, $69.99
  • Oscillating Fan 16" With Stand, $64.99
  • Non-Oscilating Clip-On Fan 6", $24.99
