Rotary Airlock Valves

KEY FEATURES AND BENEFITS

• CFR (Cubic Feet per Revolution):  Industry leading CFR allowing up to 50% more volume per revolution.  This enables the rotor to run at lower speeds than other manufacturers, increasing efficiency and equipment life.  Alternatively, it may allow for a smaller Prater airlock to be specified than the competitors.
• Castings: Precision machined, heavy-duty cast iron or stainless steel construction providing long life and durability with minimal air loss at operating temperature ranges. Designed for up to 15 psi differential pressure. Perfect for pneumatic applications.
• 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. Standard transitions required to replace competitor airlocks provided at no cost.
• Motors: Inverter-duty designed with integrated gearboxes and heavy-duty chain drives (direct drive available).
• Bearings: Easily replaceable, outboard-mounted, maintenance–free lubricated bearings.
• 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.
