KRSP PREMIUM
AIR COMPRESSORS
ou need a reliable source of compressed air that you can count on for years to come. Failure is not an option when it comes to finding an air compressor for your operations. The KRSP series of direct-drive compressors from Kaishan offers industry-leading performance in an economical package.
In a direct-drive compressor, the motor couples directly to the compressor driveshaft to power the compressor airend. Units range in size from 40 to 500 horsepower, delivering capacities up to 2,453 CFM. All compressors feature a single-stage, rotary screw design and include our patented, low speed SKY airend.
KRSP Air Compressor Benefits
All direct drive models feature low-speed operation with a 1:1 drive ratio that eliminates transmission energy loss, as well as a patented SKY airend 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.
KRSP compressors feature premium components, such as 316 stainless steel tubing and quadruple discharge bearings, with a longer service life than competitors’ duplex bearing designs. As a result, our products deliver reliable performance, shift after shift, with higher reliability and lower maintenance costs.
By combining power and reliability, our compressors help your operation stay up and running. Heavy-duty components and low speed rotating elements minimize wear and tear over time; a variety of cooling features, such as oversized air-cooled or water-cooled coolers, also maintain an ideal operating temperature to reduce the risk of overheating. Best of all, when routine maintenance is required, accessible components help keep downtime to a minimum.
Our direct drive energy-efficient compressor with patented SKY airend draws less power to meet your capacity requirements. Over the life of the compressor, even a small amount of increased energy efficiency adds up to significant cost savings. An energy-efficient air compressor is thus able to pay back a higher upfront cost of investment over the life of the equipment.
Compressor Performance You Can Count On
Other notable features available on our KRSP compressors include:
- A sound-deadening enclosure that keeps noise to a minimum and reduces the risk of occupational injury
- A range of standard safety features, such as guards for all rotating components, UL and NEC designed electrical components, and an internal spill-containment system
- Three-stage tangential oil separation system (with less than a 3 ppm rating) to keep the lubrication inside the compressor and not passing it downstream to your plant
- A Modbus compatible control system that allows for sequencing and remote monitoring of system performance, while providing alerts and protecting the unit in the event of a fault
- Centrifugal fans that deliver even airflow and more efficient cooling
- Our exclusive ‘Ultra Web’ air filter removes particles as small as five microns, keeping your compressor from ingesting dirt and wear particles that would otherwise shorten the life of your compressor
