We designed our single stage compressors to offer several long-term benefits, including:

  • Improved energy efficiency: All direct drive models feature low-speed operation with a 1:1 gear ratio that eliminates transmission energy loss, as well as a SKY air end and laminar inlet valve to deliver maximum power with minimal waste. Together, these features make our compressors some of the most efficient on the market.
  • Exceptional reliability: KRSP compressors feature premium components such as 316 stainless steel tubing and triple discharge bearings that have a longer service life than cheaper alternatives. As a result, our products will deliver reliable performance, shift after shift, with lower maintenance costs.
  • Better uptime: By combining power and reliability, our compressors help your operation stay productive for longer. Heavy-duty isolators minimize wear and tear over time, and a variety of cooling features maintain an ideal operating temperature to reduce the risk of overheating. Best of all, when routine maintenance is required, accessible components keep downtime to a minimum.

Together, these features make our KRSP compressors one of the most cost-effective options on the market today. In addition to being accessibly priced, they are also economical to run on an ongoing basis. Contact a Kaishan Compressor representative for a full cost-benefit analysis.

With superior energy efficiency, fewer moving parts and exceptionally reliable performance, the KRSP air compressor offers numerous advantages:

  • Reduced energy costs: A direct drive energy-efficient compressor draws less power to meet your capacity requirements. Over the life of this efficient air compressor, this adds up to material and significant energy cost savings. An energy-efficient air compressor is thus able to pay back the higher upfront cost of investment over the life of the equipment.
  • Reduced inventory and maintenance costs: With fewer moving parts, the KRSP requires fewer spare parts kept on hand, reducing your inventory footprint and costs. Fewer moving parts also means less wear and tear and a reduction in air compressor maintenance needs — planned and unplanned — reducing your expenditure in those areas.
  • An overall bottom line benefit: These cost savings can make a major difference in your operating costs and your bottom line over the life span of your compressor. Combined with our support and warranty services, the KRSP is well-equipped to provide benefits to your facility for years to come.


We stand behind all our compressors with a lifetime air end warranty and ongoing support from our team of experts. We maintain an extensive inventory on hand at all times. Also, 85% of our manufacturing processes are vertically integrated, allowing us to implement industry-leading quality control standards throughout our supply chain.
