How to Choose the Right Low-pressure Air Compressor

Confirm the required working pressure and air flow.
Calculate peak air consumption and reserve proper margin to offset pipeline pressure drop.
Avoid purchasing high-pressure models and manually reducing pressure, which will waste large amounts of electricity.
Analyze the production running cycle.
Choose permanent magnet VSD low-pressure compressors for fluctuating air demand.
Choose fixed-speed low-pressure machines for steady and constant air consumption.
Select integrated or split units based on workshop layout and installation space.

FAQ

What industries need low-pressure air compressors?

Low-pressure compressors are widely used in pneumatic conveying, textile, food drying and other working conditions that do not require high compressed air pressure.

What is the advantage of dedicated low-pressure compressors over high-pressure machines with pressure reduction?

Directly using low-pressure compressors avoids massive energy loss. Reducing pressure from high-pressure units will cause serious power waste.

What pressure levels do your low-pressure screw compressors support?

We provide multiple standard low pressure grades, and we can customize parameters according to customers’ actual process requirements.

Is permanent magnet VSD necessary for low-pressure air compressors?

VSD models are recommended when air consumption fluctuates. Fixed-speed low-pressure compressors are more economical for stable continuous air demand.
