Oil-free Water Screw Air Compressor

Multi-stage compression to achieve the best compression ratio and to maximize energy saving;

The piston booster uses double acting cylinders to minimize gas leakage;

The system adopts efficient energy saving motor;

Optimize the design of air pipeline system to minimize the system pressure loss;

Options of variable frequency inverter or permanent magnet synchronous motor to save energy.

The rotors adopt reasonable compression ratio, to reduce the wear and tear between rotors;

The air pipes and water pipes re made of food-grade stainless steel, which guarantees the quality of the compressed air and extends the service life of the compressor;

The intake valves and exhaust valves at all levels of the booster are optimized and designed by our company with proprietary technology, with low noise and long service life;

Skid-mounted with compact design to allow easy installation;

Easy to use, easy to replace, maintenance without lifting equipment;

A control panel controls all parts, and the graphical interface is more concise and easy to use;

The control system has a fault diagnosis function to allow you to quickly troubleshoot fault and ensure production;

A full range of safety and striking operations and warning alerts make the unit safer.

Model structure: using the overall skid-mounted, heavy welding base18 # channel steel. two groups and two cylinders; two groups share a crankshaft, to keep inertial force and inertia moment balance, and operate smoothly.

A cylinder a group Technology, Good Service ability.load evenly with good maintainability. All the Compressor first-class cylinders are double-acting cylinders, high efficiency.

Little leakage,high-efficiency,balanced compressed, Low energy consumption,longer parts ,more stable.

The screw air end is a double - axial displacement compressor

All the Connecting rods, cross-head body, and connecting rod materials are cast steel ZG310-570 with high strength.

Material is LY12, It's a cemented carbide aluminum piston.

Cross head is for whole, Slip surface covered with Babbitt. Cross pin is the floating cylindrical pin with Surface high frequency quenching hardening treatment.

Stainless steel material, Strong corrosion resistance, and abrasion resistance. Made by DMG company's proprietary technology, low noise, long operating life, large flow area, little resistance, and high efficiency.

Sealing effect: Keep the air-tightness between the piston and cylinder wall. Control the air leakage to the minimum. Supporting role: Prevent direct contact with the cylinder and support it. service life >6000hours.

Compound packing, sealing reliable, extending service life, reducing piston rod abrasion.

All 304 stainless steel are food- grade ,corrosion resistance.High temperature resistance, high reliability.

Modular, efficient stainless steel heat transfer tube structure, can be achieved not higher than the ambient temperature of 15 ℃ (or ≤ 50 ℃);

Stable start, reduce grid impact, motor start prolong mechanical life. Realize constant pressure gas supply and provide users with a stable gas source. Inverter regulation saves 20% energy consumption.

The automatic monitoring system unit operation, the graphical operation interface is more concise and easy to use, and the remote operating system can monitor the operating status and parameter changes in real time to provide customers with better services.

Centralized drain, easy management on air compressor machine room
