Made in America!

Perfect for Sticky & Low Moisture Materials

Self-Cleaning Rotary Valve Airlock

#
The Self-Cleaning Rotary Valve Airlock is the perfect metering airlock for the efficient handling of high-moisture materials that are subject to sticking, packing, and/or clogging the material handling system.
Wood, Organic and Alternative Fuel Materials

Rotary Feeder Airlock w/Knife

#
A metering device and an airlock in one! Equipped with a hardened tool steel knife so oversized materials are reduced prior to entering the delivery system. This Rotary Airlock Feeder is the preferred choice within the food processing industry.
Perfect for Eliminating Material Breakage

Side-Entry Rotary Valve Airlock

#
An offset inlet enables this rotary airlock to effectively handle fragile materials such as feedstock and pet food of relatively uniform size while minimizing breakage and material loss.
NFPA Compliant-Ideal for Abrasive Granular Materials

Extreme Duty Rotary Valve Airlock

#
NFPA Compliant and a best in class rotary valve airlock due to its industry leading, ultra tight rotor to housing clearances and abrasion-resistant materials. This airlock is perfect for handling powdery or small granule materials.
High Volume Granular & Powdery Materials

Double Slope Rotary Feeder Airlock

#
A durable high-volume rotary airlock feeder manufactured from abrasion resistant materials and designed to move massive amounts of low moisture granular and/or powdery materials types such as fly, pond, or bottom ash.
Called Upon for the Most Difficult Applications

Heavy-Duty Screw Conveyors

#
Designed to meet the unique needs of the application and manufactured by hand to ensure the highest possible quality, PMMs screw conveyors are superior in every way to “off-the-shelf” augers.

  • A common rotary feeder doing uncommon things! Not all rotary feeders are created equal! Precision Machine & Manufacturing's Rotary Airlock Feeders are uniquely sized and designed to meet the needs of the application. Equipped with a hardened tool steel knife, which helps to reduce/eliminate clogging issues by shearing irregularly sized materials down to a common size before the material exits into the pneumatic conveying system. The Rotary Airlock Feeder is the perfect addition to any organic material processing system.
  • Eliminate constant maintenance headaches. Many "off the shelf" airlocks do not take into consideration the unique aspects of the application and the material being conveyed. PMM takes the time to understand the application while ensuring we provide a solution and not just a product.
  • PMM Rotary Airlock Feeders are rebuildable! Most airlocks within the material handling industry are cast-iron, which means they are a one-time use airlock. Very similar to a disposable razor! PMM's Rotary Airlock Feeders are rebuildable, which is very similar to a reusable razor that brings more value the longer its used. When the rebuildable feature is utilized correctly, a nice exchange program is opened up, which significantly reduces CAPEX expendetures and downtime.
  • No "One Size Fits All" here at PMM! We closely evaluate every aspect of the application and specify the appropriate airlock and add-on features to meet the unique needs of the material handling application.
  • Feeding high moisture content materials into a dryer or blender? In these applications, we have had great success deploying our Self-Cleaning Rotary Valve Airlock, which makes the material handling more reliable with less sticking and clogging of hard-to-handle materials, while also offering a superior airlock performance.
  • Made in America! All PMM Rotary Airlock Feeders, Rotary Valve Airlocks, and Heavy-Duty Screw Conveyors are proudly manufactured in America by hard-working Americans whose goal every day is to provide our customers with a superior airlock!
