    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
    Image of Product. Front orientation. Blowers. High-Flow Low-Pressure Compressed Air Blowers, 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).

    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.
