KRSD
SINGLE-STAGE DIRECT
DRIVE COMPRESSOR
Air compressors, often known as the fourth utility, are a key driver of business success. As such, companies cannot risk air compressor failure during operation. Operators need a product that delivers reliable, innovative, efficient, and cost-effective compressed air, which is why many companies turn to the experts at Kaishan.


KRSD compressors utilize rotary air compressor technology to deliver a constant stream of compressed air where and when you need it most. This air compressor type uses helical screws in a continuous motion to reduce the volume and maximize the pressure of incoming air. Precision machining and proprietary bearing design within the industrial rotary screw air compressor airend hold the male and female screws, or rotors, in precise alignment.
KRSD Air Compressor Benefits
Over the years, we’ve achieved meticulous quality control by doing most of the work ourselves. Kaishan is now 85% vertically integrated by manufacturing most of our compressor components internally. This self-reliant efficiency keeps costs low for you and your single-stage direct drive compressor needs.
Our products are reliable in terms of energy efficiency. With Kaishan compressors, customers save up to 35% in energy costs. The KRSD air compressor’s male rotor maximizes compressor performance. Combined with a high-efficiency air intake, this setup optimizes efficiency for maximum energy savings.
Our air compressors are second-to-none in terms of durability. With proper maintenance, each of our compressor models can last decades, keeping customers satisfied year after year. Our products were designed and built for steady performance in rough applications. KRSD control tubing lines are built with 316 stainless steel, due to its corrosion-free properties that increase reliability.
