Why do not use PM VSD screw compressors? Because…… you will never use piston compressors again.

Difference between piston and screw compressors. In today’s industrial landscape, the application of small air compressors has become increasingly prevalent. However, choosing between traditional piston compressors and modern screw compressors has been a dilemma for many. In this comparison, we will explore the differences and advantages of small screw compressors, especially the permanent magnet variable frequency screw compressors, over their piston counterparts.

Small air compressors are integral to various industries, powering pneumatic tools and equipment. The choice between piston and screw compressors often confounds consumers due to several factors. Let’s delve into the specific advantages of permanent magnet variable frequency screw compressors in the following section.

Permanent magnet variable frequency screw compressors offer a multitude of technical advantages when compared to piston compressors.

  • Firstly, they operate at significantly lower noise levels, usually 65±3db, but piston compressors usually would be 80±3db in the same power, which making screw compressors ideal for noise-sensitive environments.
  • Their electric motors are more efficient, resulting in reduced energy consumption, usually screw compressors would be 30% energy efficiency than piston compressors in the same power, and the screw compressor has startup current is lower, preventing electrical surges.
  • In terms of maintenance, screw compressors typically require less attention, and their compact, modern design is aesthetically appealing and space-efficient (at least 15%). However, piston compressors face the most serious problem – everyone even the seller don’t want to maintain or repair a piston compressor because of low technical training levels and a lack of awareness of after-sales service.

It’s crucial to emphasize the shift towards considering lifecycle costs rather than just the initial equipment cost. This approach leads us to Caspar’s small permanent magnet variable frequency screw compressors. These units feature an IE4 energy-efficient permanent magnet motor, renowned brand inverters, high-efficiency self-developed airends, patented oil-air separation technology, and advanced cooling fans. These innovations collectively contribute to superior performance, energy efficiency, and reliability while reducing overall operating costs.

In conclusion, small screw compressors, particularly the permanent magnet variable frequency ones, have revolutionized the compressor industry. They outperform traditional piston compressors in terms of noise, motor efficiency, startup currents, maintenance, and aesthetics. As the industry trend shifts towards a focus on lifecycle costs, Caspar’s range of small permanent magnet variable frequency screw compressors stands at the forefront, offering cutting-edge technology and exceptional value to consumers.
