Blower Truck & Equipment Rotary Airlock Feeders
Original OEM Manufacturer – Built for Performance, Now Available Direct to End-Users
Precision Machine & Manufacturing (PMM) has been building high-performance rotary airlock feeders for the wood products industry since the late 1970s. Known for unmatched durability, efficiency, and throughput, PMM rotary airlock feeders have long powered the productivity of mills across the Pacific Northwest.
In the early days of the blower truck industry—well before it became a global material placement solution—a local entrepreneur partnered with PMM to adapt its proven airlock design for a specialized application: residential wood fuel delivery. That collaboration led to the development of a purpose-built rotary airlock that quickly became the heart of what we now know as the modern mulch, bark, and soil blower truck and equipment industry.
Fast forward over 40 years, and PMM’s rotary airlock feeder design remains the most widely used and trusted rotary airlock in the blower truck and blower equipment industry. Although much has changed since those early days, one thing has remained, PMM’s base airlock design continues to be the predominant feeder design used throughout the industry today and within every major variety of mulch and bark blowing equipment! Why? Because PMM is the Original Airlock OEM, and no one knows material placement rotary feeders like Precision Machine & Manufacturing!
