Our advantage


1.Air end
Larger rotors are designed to ensure the air ends have slower rotor speeds to deliver compressed air more efficiently than smaller air ends.
This translates into energy cost savings and a longer unit life.
The rotor profile minimizes leakage and the tighter clearances achieved through state of the art manufacturing processes results in higher efficiency and improved lubrication.

2.Drive Motor
IP54 rated, standard efficiency, IEC motors are used on every kaishan compressor. Over sized cast iron conduit boxes make connections easy. The industry best motor grease is used to protect motor bearings, provide longer lubricant life, greater shear stability and the best resistance to rust and corrosion.

3.Inlet Valve
The Inlet Valve is the major air flow control component in the compressor unit.It controls air flow to the compressor,either by opening, throttling, or closing completely in response to pressure transducer controls.

4.Drive Coupling
The latest European designed spider couplings are used to guarantee the reliability and transmission efficiency and provide vibration free power transmission for quiet and maintenance free operation.

5.Oil Separation System
The three stage separation system, the result of extensive research and development, supplies high quality compressed air. The separation tank has two different separation stages: Centrifugal and gravity. The third stage separation is provided by a high performance, long life coalescent separator filter. This system limits oil vapors carryover to below 3ppm.

6. Air Filter
KAPA series compressors use the Kerry air filter which provides filtration to less than 3 microns Ultra Web nanofiber technology.
This technology ensures clean, unrestriced airflow for optimal compressor operation. It has 99.99% filtration efficiency and fully complies with ISO 5011 standards. Strategic air inlet port positioning receives the coolest air as it enters the cabinet to ensure superior volumetric efficiency.

7.Cooling System
KAPA series compressors utilize a slient,efficient and easily accessible cooling system.A wide radial fan produces greater static pressure across the coolers at low rotational speed,assuring considerable energy saving and low operating sound.
