Product Specification

VSD 100% Dry Oil-Free Air - Oil-Free Air Compressors

ISO 8573-1 Class 0 oil-free (dry)screw compressor, in ISO, TUV,CE certificates with GHH oil-free air end made in Germany, patented unique design, more energy-saving, 100% Pure oil free Air compressor system for projects need oil-free discharging air.

Why our Oil-free screw compressor?

Oil-free (dry) screw compressors prevent oil contamination of the process gas. They can rotate at high speeds and are suitable for applications with large airflows and high compression ratios.

Airera offers 100% clean oil-free air compressors, that can be manufactured air-cooled and water-cooled, we can customize to special requirements and provide customized services.

 The Features of Shanghai Rotorcomp (dry) oil-free screw compressor:

1.  UItra— Energy saving GHH Oil-free screw air end

The air compression chamber is completely separated from the oil chamber. The air side adopts a non-abrasive sealing system with a stainless steel spring-loaded metal ring, and the lubricating oil side adopts a non-abrasive sealing system with a copper labyrinth seal. The two do not contact;

.2, Advanced and reliable electronic control system

Large-size color LCD touch screen, with a good human-machine communication interface, the touch screen has anti-mistouch and sleep functions;

 3, Independent double-stage air intake system

Independent air intake ensures that the intake air temperature is equal to the ambient temperature. The large-capacity air filter is used to achieve better-filtering effects, lower intake pressure loss, energy saving, and high efficiency. Maintenance and replacement are more convenient.

4) Noise reduction sheet metal design

Multiple noise reduction designs, calculated according to noise science, with special flame-retardant and sound-absorbing cotton inside to reduce unit noise.

5) Silent centrifugal fan

Adopts the advanced centrifugal fan, which has large cooling air volume, low noise, stable and uniform air pressure, which makes full use of the heat dissipation area of the cooler, and greatly reduces the noise of the air compressor by 6-8dB. Cooling air flow increases by 15%.

6) 6) Efficient water cooler

The water cooler adopts a new type of threaded finned tube shell-and-tube heat exchanger, and the compressed air goes inside the tube. The advantages are as follows: 1. The compressed air goes through the tube, which improves the pressure-bearing capacity compared with the outer finned tube.

7) Noise reduction venturi tube

The primary host and secondary host of the air compressor all adopt the newly developed Venturi tube muffler, and there is also an impedance-integrated muffler, which can greatly eliminate the noise emitted by the compressor pipeline.

8) Reliable hydraulic intake valve

The high-efficiency intake valve adopts hydraulic control, which makes the work more stable and reliable, avoids the regular replacement of pneumatic components, and reduces unnecessary downtime and maintenance costs,

9) High-reliable PM-VSD inverter from SIEMENS/ABB/HOLIP(optional)

Only select a well-known brand highly reliable inverter to keep more energy-saving performance of 12-15% than traditional design.

In an oil-free screw compressor, the air is compressed entirely by the action of the screw without the aid of an oil seal. They generally have a lower maximum discharge pressure capability, so oil-free compressors are used in applications where oil is not allowed.
