Oil-free screw air compressor is the core of a superior two compression hosts. Our rotor through twenty processes finishing the rotor linear achieve unparalleled accuracy and durability
Super coating of protection and performance
1 of the rotor and base surfaces have been super-coating process, in the figure can be seen, after surface treatment, coating firmly stuck to the rotor or the base surface.
2. Super coating is to use robot technology automatic spraying's, Pu and uniform, finally, rotor and machine seat after heat treatment, the coating in respect with the rotor or by machine Block, Lian too more firmly up.
Super coating advantages
And other coatings comparison, super coating can be described as one-upmanship, because of the super-coatings, our compressor displacement of up to 100%, and lower operating costs, the host last longer.



Power consumption water lubrication oil free compressor is currently the world's most energy-efficient models


Model for OGFD rotorcomp oil-free mechanical and electrical machine power 55 kw,

1.0 Mpa pressure, maximum displacement is after 8.60 m/min, the traditional old (dry) oil-free mechanical and electrical machine 55 kw, 1.0 Mpa pressure, exhaust is after 7.30 m/min, that is to say our oil-free machine than traditional old without oil machine with large gas production by more than 17.8%, according to the section work 6000 hours a year to calculate Q = 55 kw * 17.8% * 6000 hours * 1 yuan/KWH, electricity differ = 58740 yuan a year.


Air end long service life, safety, stability

Because water is involved in sealing, lubrication and cooling, rotorcomp oil-free screw machine operating temperature not to exceed 45 ℃; All parts are working in the condition of not more than 45 ℃, and the motor speed low (2980 r/min), so the service life of the host is very long, the host theoretical design life of 25 years, for isothermal operation also work to eliminate the error due to staff in running under the high temperature burns, fire, explosion and other unsafe factors.

Our oil-free machine can 24 hours a day, 365 days a year non-stop running workOld dry oil-free machine due to host operating temperature above 200 ℃, the screw must be high temperature resistant coatings to prevent deformation of rotor killed, but the presence of water in the compressed air, is easy to ause the disbonding, low voltage main rotor disbonding will appear the gas shortage, increase power consumption.In both cases the service life of the host and the stability is very unreliable, and the high cost of maintenance, maintenance cycle is long, and so on shortcomings.

Simple operation, convenient maintenance, low cost of after-sales service

Using rotorcomp independent research and development of software system, with functions of automatic control system maintenance alarm, automatic fault location function, automatic information storage function, the automatic alarm after the machine downtime protection function, simple operation without professional supervision, the host can 24 hours a day, 365 days a year non-stop continuous operation.

Maintenance supplies only empty water filter and filter core (ordinary dry oil-free machine maintenance cost 1/3), each maintenance within 20 minutes to complete, greatly maintaining the continuous uninterrupted gas supply requirements of users.rotorcomp rot no grease lubrication from 1 to 40 cubic all have the ability to produce and is also the most complete industry models do not grease lubricated air compressor manufacturing enterprise.


Rotorcomp air ens supply warranty 2 years, 2 years warranty is refers to the parts

should be replaced within five years, one thousand need to replace parts, all expenses shall be borne by our company.
