424CFM Industrial Reliable Air Compressor , Large Electrical Rotary Screw Gas Compressor

Specification

Features

The operation of the economic costs

The system using 0-100% capacity no level adjust. When the air comsumption decrease, the capacity is follow decrease, Motor current is also reduced; When not using air, air compressor run idle, long time run idle will automatic stop. When the air comsumption increase, recover working. Optimal effect energy saving.

Good environmental adaptability

Powerful cooling system design, especially suitable for high temperature and high humidity environment in Asia. Good technique of vibration isolation and noise reduction measures, making KAISHAN brand screw air compressor installation without special foundation, just leave a smallest ventilation and maintenance space, can placement your compressor.

The design of the screw rotor type line features:

1. Fully realized "Convex-Convex" conjunction, thus helping to form hydrodynamic lubrication film, Reduced through contact with transverse leakage, Improve the efficiency of the compressor; And improve the performance of machining and inspection on the rotor.

2. Use "big rotor, bearing, low speed" design train of thought, rotate speed 30 to 50% lower than the other brands, can reduce noise and vibration, reduce the temperature of exhaust air, improve the rotor rigidity, prolong service life, reduce the sensitivity to oil and impurities carbide.

3. Power range:4-355KW, which 18.5-250KW are direct connects not with gear box,200KW and 250KW more direct connects the 4 pole motor, low speed to 1480 r/min.

4. Fully meet or surpass GB19153-2003 <<Volumetric air compressor energy efficiency limit value>> of national standard.

All advanced parts keep high quality air compressor

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.Kerry Air Filter

Kaishan 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

Kaishan 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.
