Saman Oil-free Vortex Air Compressor, MW-3.7 High-efficiency Oil-free Vortex Air CompressorNegotiableMOQ: 1 Piece
I. Working Principle
The oil-free vortex core consists of two precision vortex disk plates, the moving disk and the stationary disk. The motor drives the moving disk to perform circular motion, and the two disks mesh with each other to form a continuous and sealed volume cavity. Air is drawn in from the periphery, and the cavity continuously contracts and compresses. Throughout the process, no lubricating oil participates in the compression cavity; only a small amount of special lubricating grease is used to isolate the air path. The compressed air does not come into contact with oil and produces a pure oil-free source.
II. Core Structure Composition
Main unit vortex machine head
High-precision aluminum alloy vortex disk, coated for anti-corrosion and wear resistance. The compression cavity is completely oil-free designed. There is no oil seal or oil mixture process.
Drive system
Two types: fixed frequency / permanent magnet variable frequency. The variable frequency model can automatically adjust the speed according to the gas usage, with extremely low no-load loss; the motor is fully enclosed dust-proof and moisture-proof.
Cooling system
Large air volume axial fan + large area heat dissipation fins, continuously removing the compression heat, with low temperature rise, ensuring long-term continuous operation.
Air path purification component
Standard: intake filter, precision oil-water separator (only for separating condensate water), storage tank. Optional: cold dryer, precision filter, for further water and dust removal.
Electrical control system
Intelligent digital display panel, real-time display of pressure, temperature, operating time, fault code, automatic start-stop, overload, high temperature, phase loss multiple protection.
Frame and sound insulation shell
Fully enclosed sound box, built-in sound-absorbing cotton, shock-absorbing foot pads to reduce vibration, the entire machine is small in size, can be placed against the wall indoors.
III. Core Product Advantages (Features)
Class 0 zero-level oil-free source
Complies with ISO 8573-1 zero-level oil-free standard, the compressed air contains no oil molecules, will not pollute terminal products and instruments, suitable for industries with high cleanliness requirements.
Ultra-quiet and low vibration
The compression process is continuous and stable, without piston impact noise, the overall noise is 50–65 dB, no need for a separate machine room, can be placed in workshops, laboratories, operating rooms.
Energy-saving and consumption reduction
Vortex compression is continuous without interruption, low loss; the permanent magnet variable frequency model adjusts pressure as needed, the no-load energy consumption is more than 30% lower than the piston machine.
Compact in size, simple installation
Integrated whole machine (air compressor + storage tank + drying and filtering in one package), no need for foundation fixation, just connect power and water supply to start production.
Low maintenance cost
The compression cavity has no oil, no need to replace the compressed oil regularly; only replace the intake filter regularly, the lubrication of the machine head is replaced every 2-3 years, the consumables are few, and the downtime for maintenance is short.
Stable and continuous gas supply
Multiple vortex cavities compress simultaneously, the air flow pulsation is very small, the output pressure is stable, there will be no significant pressure fluctuations, protecting precision equipment.
Environmentally friendly and safe
No oil discharge, no risk of waste oil treatment pollution; no oil combustion explosion hazard, suitable for high safety scenarios such as food, medical, etc.
IV. Applicable Industry Scenarios
Medical: dental clinics, operating rooms, medical oxygen supply, ventilators
Food and beverage: filling, packaging, dairy products, baking processing
Electronic and semiconductor: chips, PCB, laboratory precision instruments
Cosmetics and beauty: skincare filling, makeup production
Laboratory: research equipment, gas chromatography instrument supply
Printing, laser equipment, small precision automation equipment
V. Comparison of Advantages with Traditional Models
Compared with oil-containing vortex: oil-free air source, eliminating multi-stage oil removal filters, avoiding oil contamination of equipment;
Compared with oil-free piston machines: lower noise, less vibration, lower failure rate, more stable supply, longer service life;
Compared with screw oil-free machines: smaller volume, lower price, suitable for medium-sized gas volume (0.1–3m³/min) requirements.
VI. Normal Parameter Range
Exhaust pressure: 0.7–0.8 MPa;
Power: 1.5kW–37kW;
Air volume: 0.12~3.6 m³/min;
Noise: 52–65 dB (A);
Air source grade: ISO 8573-1 Class 0.
VII. Daily Maintenance Tips Monthly inspection / replacement of intake air filter element;
Cleaning of cooling radiator dust every six months;
Check the lubricating grease of the machine head every 20,000 hours and replenish as needed;
Manual discharge of condensate water from the air storage tank every day;
Regular inspection of pressure sensors and electronic control circuits.
VIII. Product Weaknesses (Objective Explanation)
It is inferior to oil-free screw machines in high-flow conditions; the cost-effectiveness decreases for models above 3m³/min;
The rotor is highly precise and must not be subjected to dust particles; a pre-filter must be installed;
Long-term operation at extremely high pressure will shorten the lifespan of the machine head; it needs to be matched with the rated pressure condition.
