Heater and Air Conditioner Duct Booster Fans
 |
Insert these fans directly into your ductwork. They give small heaters and air conditioners a boost to circulate air through ductwork. The crimped end construction makes inserting the fans easy.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

Direct-Drive Duct Fans
 |
Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Also known as axial duct fans, these install inline in ductwork for use as an exhaust, supply, or booster fan. All fans have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.

Direct-Drive Corrosion-Resistant Duct Fans
 |
A galvanized steel housing offers good corrosion resistance. All of these direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. Also known as axial duct fans, they install inline in ductwork for use as an exhaust, supply, or booster fan. The fans have a totally enclosed motor enclosure, which can be used in dirty, dusty, and damp environments.
