High-Output Blowers

Powerful and durable, these blowers are able to blow air through larger systems that have more airflow resistance than standard blowers can handle. They install in ductwork similar to duct fans, but are for use where high static pressures are present. Use them for equipment cooling, drying, ventilating, and exhausting. Blowers that weigh 280 lbs. or less can also be used for material conveying.

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.

Floor-Mount Fume Exhausters

Aluminum

Mount these exhausters to the floor to remove fumes, vapors, and fine dust particles from your space. They are commonly used in welding, soldering, and other operations that create fumes.

Totally Enclosed Motor Enclosure—Totally enclosed exhausters have an external fan for cooling. These exhausters offer more protection than open dripproof exhausters. They can be used in dirty, dusty, and damp environments, but are not airtight.

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

High-Flow Low-Pressure Compressed Air Blowers

Also known as regenerative blowers, use these to produce high-flow compressed air with low pressure or vacuum to operate pump drives, lift tables, and conveying systems. Compressed air blowers are also used for drying, exhausting, and aeration.

Air circulates inside the blower housing to compress air, which generates pressure or vacuum.

Single Stage

Single-stage blowers circulate air once and then exhaust.

Inverter Rated—Inverter-rated blowers have a motor that can run at slow speeds without overheating, so they can be used with a motor speed control (variable frequency drive).

Belt-Drive Corrosion-Resistant Duct Fans

A 304 stainless steel housing offers good corrosion resistance. All of these belt-drive fans 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. 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.

Direct-Drive Upblast Roof-Mount Exhaust Fans


Style 1	Style 2

Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance. These exhaust fans draw stagnant and humid air out through your roof and then expel it up and away from the roof surface. All fans have a disconnect switch to turn off the power for servicing.

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

Cannot Be Sold To—Fans that cannot be sold to the listed areas are restricted by energy efficiency requirements.

Hanging Box Fans

Easily hang these fans from your ceiling using the attached bracket and a mounting chain kit (sold separately). They're more powerful than our standard box fans. Made with a heavy duty 12-gauge welded wire mesh guard, these fans will stand up to tough environments. Plastic guard clips help reduce vibration between the housing and the guard, making these fans quieter. They require little maintenance thanks to their totally enclosed, high-efficiency motor and sealed ball bearings.
