ROTARY AIRLOCK VALVES

Minimize air pressure loss and increase efficiency in bulk material processing and production operations

Prater’s Rotary Airlock Valves can be configured and customized for most application requirements, especially for materials that may be highly abrasive. We understand the need for feeding more material at lower speeds, which is why our rotary airlock feeders are manufactured with larger pockets. In turn, this design minimizes air leakage, provides the benefit of longer life, and ensures a higher return on investment.

Key Features and Benefits

• CFR (Cubic Feet per Revolution):  Industry leading CFR allowing up to 50% more volume per revolution. 
• Castings: Precision machined, heavy-duty cast iron or stainless steel construction providing long life and durability with minimal air loss.
• Universal Flanges: Oversized design able to accommodate multiple bolt patterns for a wide range of installations.
• Rotors: Precision machined eight-blade, heavy-duty fabricated design ensures minimal deflection and improved seal as compared to 6 blade designs.
• Design: Compact size and head height allows for easy installation or replacement of most competitors airlocks.
• Motors: Inverter-duty designed with integrated gearboxes and heavy-duty chain drives (direct drive available).
• Bearings: Easily replaceable, outboard-mounted, maintenance–free
• Packing Glands: Self-adjusting design ensures consistent load on packing to reduce leakage and help extend shaft seal life. Designed for simple maintenance.
• Operating Temperature: Standard models operable up to 500 ℉. Custom models up to 1000℉.
• Standards: Compliant with NFPA-69 standards. Third-party tested.
