Blower Truck & Equipment Rotary Airlock Feeder

Precision Machine & Manufacturing is the original OEM of rotary airlock feeders for the blower truck and mulch blowing equipment industry. Trusted for decades by leading material blower truck and equipment manufacturers, PMM is widely recognized as the industry expert in rotary airlock technology. PMM’s rotary feeders are purpose-built for the material placing and blowing industries and are used in pneumatic material blowing systems that place a variety of materials ranging from mulch, bark, soil, and straw to grass seed and various types of rock and aggregate. PMM rotary airlocks are known for their exceptional sealing performance, long-lasting durability, and proven reliability.

If your feeder has a serial number stamped on the lower left corner of the drive or non-drive endbell, it is likely a genuine PMM original.

A failing rotary airlock reduces blowing efficiency, increases maintenance costs, unplanned downtime, which ultimately results in lost revenue. PMM maintains a full inventory of complete rotary airlock feeders and replacement parts—stocked and ready to ship.
