Kalpataru’s rotary airlock is an ideal choice for handling many dry, free-flowing powders where a pressure differential exists, such as when feeding pneumatic conveying lines. Constructed from either stainless steel or cast iron, our RAL withstands extremely high temperature applications. The Rotary Airlocks are available in all standard as well as customized convenient sizes with optional coatings or construction materials available for handling abrasive or corrosive materials and equipped with chain drive gear-motors and your choice of speed. Inlets and outlets are available in many common sizes and we also offer designs built to your unique application.
