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 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.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

Exterior-Wall-Mount Exhaust Fans
120V AC, Single Phase (Hardwire)—Open Dripproof (ODP) Motor Enclosure
 |
Fans with an open dripproof (ODP) motor enclosure should be used in clean, dry, and indoor locations. You can use these fans with or without duct. To use them with duct, you'll need an angle ring (not included).
Direct Drive—Direct-drive fans have fewer moving parts than belt-drive fans, so they’re easier to maintain.
Grilles—Grilles (sold separately) have fixed blades.
Louvers—Louvers are gravity operated. The blades open when air flows and close when it stops, preventing backdrafts.

230/460V AC, Three Phase (Hardwire)—Totally Enclosed Motor Enclosure
|
Fans with a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments. They mount through the wall, so you'll need to cut a hole on the inside of the wall as well.
Direct Drive—Direct-drive fans have fewer moving parts than belt-drive fans, so they’re easier to maintain.
Belt Drive—Belt-drive fans are quieter than direct-drive fans. They also last longer because their components can be replaced if damaged.

Direct-Drive Hazardous Location Duct Fans
|
These fans have an explosion-proof motor that is UL listed for Class I, Divisions 1 and 2, Group D; and Class II, Divisions 1 and 2, Groups F and G hazardous environments. All are direct-drive fans that 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 TEFC (totally enclosed fan cooled) motor enclosure, which can be used in dirty, dusty, and damp environments.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.

Belt-Drive Hazardous Location Duct Fans
|
These fans have an explosion-proof motor that is rated for hazardous environments. All are belt-drive fans that are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. They install inline in ductwork for use as an exhaust, supply, or booster fan. UL and CSA standards apply to the motor.
Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water.
IP44 Enclosure Rating—Fans rated IP44 have a motor enclosure that's rated for protection in damp environments.
IP56 Enclosure Rating— Fans rated IP56 have a motor enclosure that’s rated for protection in damp, dusty, and washdown environments.
