Air Lock Feeder Services

OP Engineering Group is a leading manufacturer and supplier of high-performance Air Lock Feeders (Rotary Airlock Valves) used in cement plants, sponge iron (DRI), power plants, chemical industries, and bulk material handling systems.

With a strong focus on precision engineering and durability, OP Engineering Group provides robust and efficient airlock feeders that ensure controlled material discharge while maintaining pressure sealing in pneumatic conveying and dust handling systems.

Our airlock feeders are designed for continuous operation, high efficiency, and long service life even in harsh industrial environments.

An Air Lock Feeder, also known as a Rotary Airlock Valve, is a mechanical device used to regulate the flow of bulk materials from one chamber to another while maintaining an airlock seal.

It works on the principle of a rotating rotor with multiple vanes that allow material to pass through while preventing air leakage between different pressure zones.

This ensures:

• Controlled material flow
• Air leakage prevention
• Efficient dust handling
• Smooth operation in pneumatic systems

OP Engineering Group manufactures airlock feeders in a wide range of sizes and configurations:

• Size Range: Customized as per requirement
• Material: Cast Iron, Cast Steel, Stainless Steel
• Rotor Type: Open / Closed Rotor
• Drive Type: Direct Drive / Chain Drive / Gearbox
• Temperature Range: Suitable for high-temperature applications
• Capacity: As per application
• Mounting: Flange type / Square / Round

Our feeders are designed to handle abrasive, powdery, and granular materials efficiently.

Air lock feeders are widely used in various industries:

• Cement Plants
• Sponge Iron (DRI) Plants
• Power Plants
