Airlock Feeder, which is equipped with a hardened tool
steel knife, is the preferred rotary airlock whenever
moving irregular sized materials requires a reduction
in size prior to entering the conveying system.
Self-Cleaning Rotary Valve Airlock is the most durable
self-cleaning rotary airlock in the industrial
manufacturing industry. A proven history of
eliminating components, which are prone to clogging.
Duty Self-Cleaning Rotary Valve Airlock is the most durable self-cleaning rotary airlock in the industrial manufacturing industry. A proven history of eliminating material handling components that are prone to clogging.
Duty Rotary Airlock Feeder is the most durable high volume
rotary airlock in the industrial manufacturing industry.
When moving massive amounts of material is needed, this
airlock will exceed expectations!
Rotary Valve Airlock is the perfect Rotary Airlock for moving
fragile materials that are prone to breakage. Manufactured
with abrasion-resistant materials and is totally rebuildable!
Will last at least 3x’s longer than cast-iron airlocks!

Heavy-Duty Rotary Airlock Feeders, Rotary Valve Airlocks, and Screw Conveyors that simply move massive amounts of material, with far greater efficiency, while experiencing significantly less downtime & maintenance costs.
Quality Heavy-Duty Airlocks from the Experts
“The PMV-8 reduced maintenance costs by $60,000 per year!”
“Due to the high wear rates of our old (cast-iron) rotary airlocks, we began to see material leakage and diminished airlock functionality almost instantaneously after being installed. We replaced these airlocks with PMM’s ultra-duty rotary valve airlock, and they ran for two whole years with zero maintenance issues, no loss in throughput, and no unscheduled downtime.”
“An added bonus is that PMM’s rotary valve airlock has reduced capital costs of future valve installations by 85%!”
“Precision’s rotary valve airlocks have MADE my plant what it is today!”
“The installation and cost of ownership for the old (cast-iron) rotary valve was 12-times more than the PMV-8 while also requiring a large footprint and an even larger amount of utilities.”
“The old (cast-iron) airlocks were not rebuildable, so our only option was to replace them, which got expensive. Because PMM’s rotary valve airlocks are rebuildable, we could order direct replacements from PMM, schedule the maintenance, and have a quick shut down to quickly replace the worn components. Minimal downtime!”
“PMM’s Rotary Valve Airlock significantly reduced the amount of product lost.”
“PMM’s representatives are continuously offering up suggestions and ways to improve our operations.”
“The operators are happy with the airlock because it is easy to operate and performance does not degrade as fast as the old (cast-iron) rotary valve.”
“The coal mill valve was constantly getting clogged and required daily cleanings, which was a maintenance headache. We replaced the coal mill with PMM’s self-cleaning valve and it ran for 2-years with ZERO maintenance.”
“PMM’s PMV-8 wears much slower, which provides a predicable leakage and stabilizes the process.”
“Precision’s rotary valve outlasted the old (cast-iron) valve, by four of the old to one of PMM’s!”
“Maintenance technicians enjoy the PMV-8 because it is so easy to maintain.”
“The old (cast-iron) rotary airlocks did not allow for rebuilds so our only option was to replace them. PMM’s Rotary Valve Airlock is 100% rebuildable providing a superior cost of ownership!”
“Our old (cast-iron) rotary valve had to be taken out of service (a lengthy process) and the nylon pads changed. When PMM’s rotary valve airlock does require maintenance, it just requires the removal of a few bolts, the barrel side rotated, and back into service. Super-fast and minimal downtime!”
“The old (cast-iron) valve would begin wearing almost instantaneously after installation, which is a stark contrast to PMM’s rotary valve that ran for two years with no loss in airlock functionality.”
“In comparison, the old (cast-iron) valve required maintenance every two months. PMM’s rotary valve airlock has been running for five months and there are no signs of wear.”
“PMM’s representatives are a trusted partner.”
“Precision Machine & Manufacturing has offered superior customer support and has a knowledgeable and courteous staff who is a pleasure to deal with.”
“I look forward sustaining this sense of partnership as we work together to improve an already superior product for the price.”
