Low-Pressure Blowers | McMaster-Carr

Measured in decibels (dB), volume ratings indicate how much noise equipment makes. Some common volume levels include a whisper @ 20 dB, a refrigerator @ 40 dB, a conversation @ 60 dB, and a light machine shop @ 90 dB. OSHA recommends hearing protection for exposure to 80 dB and greater.

About Air Compressors

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 blowers circulate air once and then exhaust. Two-stage blowers circulate air twice and then exhaust, creating higher pressure or vacuum than single-stage blowers with the same horsepower.

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).

High-Flow Low-Pressure Hazardous Location Compressed Air Blowers

Safely produce high-flow compressed air with low pressure or vacuum in environments with flammable gases and combustible dust, such as propane and carbon-based dust. These blowers have an explosion-proof motor and are UL listed for use in hazardous locations. Also known as regenerative blowers, they are commonly used to operate pump drives, lift tables, and conveying systems. They can also be used for drying, exhausting, and aerating.

DC Blowers

Operate these blowers with a DC power source, such as your vehicle battery. Use them for equipment cooling, material conveying, drying, ventilating, and exhausting.

Blowers with a totally enclosed motor enclosure can be used in dirty, dusty, and damp environments.

Blowers with a multidirection mounting bracket can be rotated to discharge air in any direction.

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

Blowers

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 an open dripproof motor enclosure for relatively clean, dry, indoor locations.

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

Chemical-Resistant Blowers

For resistance to chemicals as well as corrosion, these blowers have a plastic housing. They 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 damp environments.

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

Fiberglass housing withstands organic chemicals, such as ammonia, antifreeze, and mineral oils.

PVC plastic housing offers greater chemical resistance than the fiberglass housing. It resists strong oxidizing acids such as sulfuric acid but will not withstand contact with perchloric acid.

Blowers that cannot be sold to the listed areas are restricted due to energy efficiency requirements.

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.
