Hazardous Location Spark-Resistant Blowers

These blowers have an explosion-proof motor that is UL listed for hazardous locations. They also have an aluminum housing for spark resistance. These blowers install in ductwork similar to duct fans, but are for use where high static pressures are present. Use them for equipment cooling, material conveying, drying, ventilating, and exhausting.

Note: Airflow depends on the resistance created by ductwork. This resistance, known as static pressure (SP), is measured in inches of water. It is the responsibility of users in California to follow local energy efficiency regulations. Operating these blowers at a high airflow may violate these regulations.

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.
