Air Lock Feeder Manufacturer & Supplier – OP Engineering Group

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.

What is an Air Lock Feeder?

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
