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 be powered for subsequent further 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 main body 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.
Durable solutions that require minimal maintenance - This is because they have fewer moving parts than other types of compressors, such as reciprocating systems. For example, our rotary vane technology has no gears or belts, which means that there are fewer parts that are prone to wear or friction. This in turn reduces the need for continuous replacement of moving parts and the resulting unnecessary downtime.
Low noise levels - This is again achieved through its innovative design and few moving parts, which reduces vibration and noise and creates a quieter working environment.
Long life expectancy - Rotary vane compressors are often praised for their long life expectancy, especially when compared to other alternatives. With fewer moving parts as mentioned above and a robust design, rotary vane solutions are the perfect long-term investment for your compressed air needs.
