Controlled Material Feeding for Pneumatic Conveying Systems
Cyclonaire Rotary Airlock/Feeders are designed to provide controlled material feeding into dilute-phase pneumatic conveying systems while helping maintain system pressure and consistent material flow. Sized for each application, these airlocks can be configured with custom rotor types to match material characteristics, process requirements, and conveying performance goals.
The shaft drive is built for heavy-duty operation and minimal deflection, while the inlet throat is optimized to support efficient product feeding. Motor and gear reducer options are selected for the application, helping ensure the airlock feeder performs reliably within the broader material handling system.
Available in a range of materials, rotor styles, inlet/discharge configurations, and control options, Cyclonaire Rotary Airlock/Feeders provide a flexible solution for applications requiring consistent feed rates, air leakage control, and dependable pneumatic conveying performance.
