KAITAIN JN75-8 Stationary Electric Rotary Screw Air Compressor(Air Cooled)

1.Drive Motor

IP54 rated,standard efficiency,IEC motors are used on every KAITAIN 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.

 2.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.

3.Airend · Direct Driven --- No Gearing, No Belt!

Rotors are the key elements in producing compressed air efficiently.KAITAINairends utilize a male 5 lobe rotordriving rotorand a 6 lobe female rotordriven rotor).These state of the art Y profile rotors were introduced in the KAITAIN series compressor. 

They have the following characteristics:

Larger rotors are designed to ensure the airends have slower rotorspeeds to deliver compressed air more efficiently than smaller airends

This translates into energy cost savings and a longer unit life.

The airends are guaranteed for 5 years.The rotor profile minimizes leakage andthe tighter clearances achieved through state of the art manufacturing processes results in higher

efficiency and improved lubrication.

4.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. 

5.Oil Separation System

The threestage 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. The efficiency of the first two stages assures the long life of 

this coalescent filter. This system limits oil vapors carryover to below 3 ppm.

6.Kerry Air Filter

KAITAIN 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

The cooling efficency of a compressor is of vital importance to ensuring reliability and efficiency. The Kaitain Series compressors use an advanced design axial fan. The fan blade-end tip angle is designed to maximize the air volumetric flow rate cooling the high temperature lubricant oil and compressed air. A large surface area cooler with optimal fin design has been included to provide maximum cooling and longer operating life.

8.Oil Separation System Continue

The air purity meets ISO standard 8573-1:1991, Class 3 Oil Residues. Kaitain's oil separation system is monitored by an alarm system on the electronic control panel.
