Rotary Air Lock
The primary function of a Rotary Airlock Valve is to control the flow of solid materials, such as powders or granules, while maintaining an airlock condition. The device typically features a rotating element (rotor) with multiple vanes or blades within a cylindrical chamber. As the rotor turns, it picks up material from the inlet, moves it through the chamber, and discharges it at the outlet.
This process controls material flow and prevents air from passing between the inlet and outlet, crucial for maintaining pressure differentials in certain systems.
Rotary Airlock Valves are widely used in industries like agriculture, chemical manufacturing, and food processing, where efficient and controlled handling of bulk materials is essential. Atmax Filtration also supplies stainless steel and ATEX certified Rotary Air Lock Valves.
