4.8A Fans | McMaster-Carr

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.

Fans with Totally Enclosed Motor Enclosure

Direct Drive—Direct-drive fans have fewer moving parts than belt-drive fans for less maintenance.

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.

IP56 Enclosure Rating— Fans rated IP56 have a motor enclosure that’s rated for protection in damp, dusty, and washdown environments.

Corrosion-Resistant Blowers

A 304 stainless steel housing offers good corrosion 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. All blowers have a totally enclosed motor enclosure, which can be used in dirty, dusty, and wet environments.

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

Dust-Resistant Belt-Drive Wall-Mount Exhaust Fans

Better suited for dirty, dusty, and damp environments than standard direct-drive fans, these have a totally enclosed motor enclosure. Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. Use these fans to draw stagnant and humid air out of a room or area.

Belt-Drive Duct Fans

Belt-drive fans are quieter and have a longer life span than direct-drive fans because components can be replaced if worn or damaged. 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.

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

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.

Exterior-Wall-Mount Exhaust Fans

Good when you don't have room to mount an exhaust fan inside your facility, these fans attach to openings in outside walls. Use them to draw stagnant and humid air out of a room or area.

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

120V AC, Single Phase (Hardwire)—Open Dripproof (ODP) Motor Enclosure

Image of Product. Front orientation. Open Dripproof (ODP) Motor Enclosure. Exterior-Wall-Mount Exhaust Fans.

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.

Oil- and Coolant-Removing Air Purifiers


	Replacement Filters

Often used in machine shops, these purifiers remove oil and coolant mist from the air. Air passes through a spinning drum.

Cannot Be Sold to California—Purifiers that cannot be sold to California are restricted due to energy efficiency requirements.
