The Dust Collector Series rotary airlock is a budget-friendly, economical choice for general use under dust collectors, cyclones and hoppers. The standard features on our Dust Collector Series rotary airlocks are typically found only on heavy-duty airlocks. Eight-blade rotors, precision machining and rugged cast-iron housings all ensure an efficient operation from start to finish. The eight-blade rotor provides two additional tips to seal against air leakage while heavy cast iron housing and end plates ensure maximum rigidity. Dust Collector rotary valves can easily be configured for most application requirements. Since our rotary airlocks are designed with larger pockets, for up to 50% more volume, they can run at lower speeds. This ensures longer life, less maintenance and a higher return on investment for your company. Prater-Sterling understands that temperature plays a significant role in the operation of rotary airlocks, they ensure that each of our products is carefully machined for actual operating temperature at no extra charge.
Heavy Duty PAV Series Airlock
- Up to 500° F with standard components
- Up to +/- 12 PSI pressure differential
- Cast Iron or stainless steel construction
- Chain drive gear-motors (choice of speed)
- Available in nine convenient sizes
Prater Sterling’s Heavy-Duty PAV Series rotary airlock is an ideal choice for handling many dry, free-flowing powders where a pressure differential exists, such as when feeding pneumatic conveying lines. Constructed from either stainless steel or cast iron, the Heavy-Duty PAV Series allows up to +/- 12 PSI pressure differential and 500°F with standard components. Available in nine convenient sizes, optional coatings or construction materials are also available for handling abrasive or corrosive materials. We offer high-temperature kits for up to 1,000°F. Equipped with chain drive gear-motors and your choice of speed, these hard-working units are available in six popular square size openings as well as larger capacity machines with rectangular openings.
Large rectangular flanges allow for greater capacity and a reduced height. All three sizes, including the 14″x20″, 18″x24″ and 28″x30″, use one-piece cast bodies with reinforcing ribs for minimal deflection under the severe stress that large processing systems can impose. Heavy-Duty PAV Series rotary airlock transfers dry, bulk materials from large bins to pneumatic systems against pressure. Used for many applications and with many materials, the Heavy-Duty PAV Series is ideal for companies of all sizes and types. The smallest Heavy-Duty rotary valve is 6″, and we also offer 8″, 10″, 12″, 14″, 16″, 18″x24″, 28″x30″ or 14″x20″ models to easily fit into your company’s workspace.
