China 30 HP 127 Cfm 8 Bar Direct Driven Screw Air Compressor

Product description
DC series Screw Air Compressor Instruction:
The DC series compressor represent a giant leap in design and performance with each component designed for reliability and ease of maintenance. The compressor is manufactured in compliance with applicable international standards CE,IAF and others and designed as per the international quality standards. These new generation compressor significantly reduce operating costs and provide cost savings with fast return on investment.
The DC series industrial screw air compressor comes configured as direct driven(7.5kW - 400kW) with discharge pressures from 0.7MPa to 1.3MPa ( 7~13Bar ). And can variable frequency.
Product Application
Rotors are the key elements in producing compressed air efficiently. KAISHAN airends utilize a male 5 lobe rotor driving rotor and a 6 lobe female rotor(driven rotor).These state of the art Y profile rotors were introduced in the LG series compressor.

They have the following characteristics:
1.Larger rotors are designed to ensure the airends have slower rotor speeds to deliver compressed air more efficiently than smaller airends
2.This translates into energy cost savings and a longer unit life.
3.The airends are guaranteed for 2 years. The rotor profile minimizes leakage and the tighter clearances achieved through state of the art manufacturing processes results in higher.
4.efficiency and improved lubrication.

Main Features
Fully seal & double screw,dual shock proof,smooth operation,can be installed anywhere.
♦ With a exquisite shape and compact structure and cover a small area.
♦ Large displacement,stable pressure and high efficiency.
♦ Low exhaust temperature (only 7 °C~10°C higher than the ambient temperature)
♦ Safe,liable,smooth operation,little noise and long maintenance cycle and using life.
♦ The intelligent control system completely satisfy the continuous cooperation without man work.
♦ Many screw air compressors operate together and start or shut down automatically according to the air amount,and no man-work is needed.
♦ It is more energy saving for a single compressor can adjust air demand automatically according to the users' air amount(frequency conversion type).
♦ The degree of tightness of the belt can be auto-matched with the flexible belt. Through adjusting the tensility, the loss of the pressure and efficiency can be reduced to the lowest point and increase the time efficiency of pressing.

♦ Narrow belt has higher transmission power with efficiency of about 98%.the structure can reduce internal heat and prevent aging. It enjoy Longer service life and much lower stretch ability.

Economic operation
The system adopts stepless capacity regulation of 0-100%. When the gas consumption is reduced, exhaust volume decreases, the motor current decreases at the same time; when no gas, air compressor run empty, empty for too long the automatic shutdown. When the gas consumption increases, the resumption of heavy truck. Energy-saving effect is optimal.
