A rotary vane air compressor consists of a cylindrical housing vessel containing a set of adjustable rotating vanes and exchanging air through an inlet and outlet. The vanes are set on an eccentric drive shaft which faces the outlet. As the drive shaft rotates, the length of the adjustable vane closest to the outlet shortens, compressing the air within the spinning chamber. This air then escapes through the outlet and can power further subsequent processing. Rotary vane air compressors are ideally suited to small and quiet applications such as the automotive and agricultural industries. They are less suitable for applications requiring oil-free or otherwise uncontaminated air, or for use in potentially contaminated environments such as wood shops.
The mainframe consists of a plurality of sliding blades set in a rotor that rotates around an eccentric shaft in a static airtight cylinder. As the rotor turns, centrifugal force causes the blades to slide and extend into the longitudinal grooves of the rotor. In the extended state, these blades function like vanes, adjusting to the shape of the cylinder as the rotor is driven. When the pressure-driven intake valve (regulating piston) opens, incoming air enters the main unit. This happens once the designed operating conditions are reached. The air is drawn into the cylinder by the rotating vanes, which seal the space as they pass through the compression area. Due to the eccentricity of the cylinder walls and rotor, the volume between the blades is reduced and the air is compressed. After maximum compression, the air is discharged through an outlet. In the compressor, the intensive injection of coolant reduces the overall temperature of the compression cycle and ensures adequate lubrication. The injected coolant also acts as an active sealant to keep the blades airtight.
Simple design with few moving parts
Rugged, compact construction, easy to access and maintain, easy to replace parts, extremely reliable and durable.
Direct axial coupling to the motor
Direct couplings are possible because high compression ratios allow low speeds, eliminating the need for transmissions or gears. Fewer parts mean lower energy consumption and simplified maintenance.
Low rotational speeds
Lower rotational speeds reduce vibration, which reduces noise and wear, lowers temperatures and eliminates the need for concrete foundations.
Low maintenance costs
Single-stage rotary vane units have low wear and fewer parts, providing cleaner, more reliable operation, which significantly reduces maintenance requirements.
