Rotary Screw Air Compressors


World-Leading Rotary Screw Air Compressors

Kaishan USA is a premier supplier of rotary screw air compressors. Rotary screw air compressors are popular in factories, plants, and manufacturing facilities in general due to their ability to run non-stop around the clock. As long as a screw-type air compressor is sized correctly, its efficiency is superior to most other air compressors on the market.

Rotary Screw Air Compressor Types

There are two models of rotary screw air compressors on the market today: oil-injected and oil-free. Oil-injected rotary air compressors use oil injected into the screw compression chamber to lubricate the bearings, remove the heat of compression and seal the area between the two rotating screws to efficiently produce clean, cool compressed air. This process is sometimes known as an “oil bath” or “oil-flooded” lubricated compression. Oil-free rotary air compressors, on the other hand, do not flood their compression chambers with oil; rather, they operate at high speeds and very high temperatures with a dynamic seal and multi-staging to achieve respectable efficiencies.

Oil-injected compressors will require more routine maintenance, but will have a lower total cost of ownership as compared to an oil-free screw compressor. Kaishan offers both oil-lubricated and oil-free rotary screw designs to fit any end-use application. We want our customers to have the best, which is why we only sell the best.

Kaishan offers multiple models of lubricated rotary screw compressors:

KRSB compressors deliver reliable, economical compressed air for several industrial applications. Available tank-mounted with capacities ranging from 5 HP to 50 HP.

KRSD single-stage direct drive compressors are one of our most popular solutions. With a standard 10-year airend warranty, the KRSD is designed to deliver a constant stream of compressed air where and when you need it most.

KRSP compressors are one of the most cost-effective options on the market. Delivering reliable performance, shift after shift, with lower maintenance costs and faster ROI, the KRSP series features a lifetime airend warranty.

KRSP2 two-stage rotary screw air compressors are the most energy efficient of its kind anywhere in the market. We are so confident in its world-class design and reliability, in fact, we offer a lifetime airend warranty to back our claims.

KRSL low-pressure rotary screw air compressors can effectively handle applications ranging from 25 psig to 45 psig, all within a single package.

The KROF two-stage oil-free rotary screw air compressor represents Kaishan’s commitment to catering to the growing demand for oil-free air across various industries.
