Compact 500-liter vertical air receiver mounted on a heavy rigid vibration base

Permanent magnet variable speed screw compressors OPPAIR PM VSD

Rotary screw compressors OPA / OPPAIR PM VSD with permanent magnet synchronous motors modulate air delivery to match actual plant demand. Direct coaxial drive eliminates transmission losses and mechanical belts while minimizing electric current spikes during start-up cycles.

Energy consumption reduction exceeding twenty percent against fixed machines
High-efficiency permanent magnet synchronous motor with elevated power density

Direct-coupled drive assembly removing belt maintenance and side-load forces

Industrial fixed speed rotary screw air compressors OPP series

Industrial rotary screw air compressors OPA / OPPAIR OPP series operate at fixed rotational speeds for base-load industrial pneumatic networks. Asymmetric rotor profiles and heavy-duty oil reservoirs maintain thermal equilibrium during continuous multi-shift production runs.

Electric drive power ratings ranging from 7.5 kW up to 132 kW for industrial utility
Discharge pressure settings available at 7, 8, 10, and 12 bar configurations
Heavy-duty precision roller bearings engineered for extended operating hours
Sound-dampening enclosure with removable access doors for quick lubrication

Two-stage high-pressure rotary screw air compressors OPPAIR

Two-stage rotary screw compressors OPA / OPPAIR divide compression between two rotor stages with interstage oil injection cooling. This configuration lowers the pressure ratio across each stage, curtails volumetric slippage, and extends overall bearing fatigue endurance.

Interstage fluid injection cooling controlling air temperature between pairs
Reduced mechanical forces acting on rotor roller bearings and high-pressure seals
Higher volumetric output compared with standard single-stage compression equipment
Discharge pressure capability reaching 16 to 20 bar for industrial processes

Mobile diesel-driven portable rotary screw air compressors OPA

Mobile diesel-driven screw compressors OPA / OPPAIR provide self-contained compressed air power for remote construction and drilling operations. A rugged wheeled chassis with adjustable towbar and dependable diesel engine ensure reliable operation beyond utility grids.

Self-contained heavy-duty industrial diesel engine with liquid cooling loop
Towable chassis fitted with pneumatic road tires and integrated mechanical brake
Weather-resistant acoustic canopy protecting internal units from rain and dust
Multi-valve discharge manifold allowing simultaneous multi-tool air connections

Compressed air preparation equipment: refrigerated dryers and tanks OPPAIR

Compressed air treatment solutions OPA / OPPAIR encompass refrigerated and desiccant air dryers, vertical receivers from 300 to 3000 liters, and inline coalescing filters. These components extract condensate, oil mist, and particulates to protect downstream pneumatic tools.

Refrigerated dryers maintaining a steady pressure dew point of plus three degrees
Desiccant twin-tower air dryers achieving deep dew point down to minus 40 degrees
Vertical air receiver tanks protected by internal protective epoxy lining coat

Engineering layout and design of integrated 4-in-1 laser cutting compressor stations

Integrated 4-in-1 compressed air stations OPA / OPPAIR are specifically engineered to provide continuous assist gas for sheet metal fiber laser cutting machinery.

Unlike decentralized piping networks, this skid-mounted system integrates a rotary screw air-end, a 500-liter vertical air receiver, a refrigerated air dryer delivering a plus three degree dew point, and four progressive coalescing filter stages within a single rigid vibration-isolated frame.

This integrated layout eliminates oil aerosols and moisture in the assist gas stream, protecting sensitive laser cutting optics from contamination while preventing heat oxidation and dross formation along cutting edges.

Energy efficiency principles and vector frequency inverter regulation in PM VSD series

Rotary screw air compressors OPA / OPPAIR equipped with permanent magnet synchronous motors and PM VSD frequency inverters modulate output flow to match dynamic industrial consumption.

The frequency inverter smoothly adjusts rotor rotational speed between 25% and 100% of full load, eliminating idle unloading cycles and severe electric start-up current surges.

The permanent magnet synchronous motor achieves high power factor ratings and IE4 efficiency standards, delivering full torque output even at low operating speeds. This delivers energy reductions between 20% and 35% compared with conventional fixed speed compression systems.

Fluid dynamics and thermal cooling management in fixed speed OPP rotary compressors

Industrial rotary screw compressors OPA / OPPAIR belonging to the standard fixed speed OPP series deliver uninterrupted round-the-clock air volume for manufacturing plants. Asymmetric rotor profiles optimize internal chamber volume while minimizing specific power consumption during air compression.

Circulating compressor fluid serves multiple functions: sealing micro-clearances between male and female rotors, providing lubrication to heavy-duty radial and thrust roller bearings, and dissipating heat through an air-cooled radiator core.

An internal thermostatic valve maintains fluid operating temperature between 75 and 85 degrees to prevent internal condensation.

Thermodynamic advantages and stage pressure balancing in two-stage screw compression

Two-stage high-pressure screw compressors OPA / OPPAIR divide overall air compression into two successive stages with interstage fluid cooling.

Reduced compression ratios across each individual stage curtail internal air slip through rotor tolerances and reduce mechanical thrust forces on supporting bearing assemblies.

Injecting cooled fluid between the primary and secondary compression chambers brings the cycle closer to ideal isothermal compression, elevating overall isentropic efficiency across the entire unit.

This design allows the compressor to reach working discharge pressures of 16 to 20 bar while maintaining reduced specific power demand.

Operational durability and mechanical design of mobile diesel-driven screw compressors

Mobile diesel-driven rotary screw compressors OPA / OPPAIR deliver reliable autonomous pneumatic power for remote mining quarries, road construction sites, and portable drilling rigs.

The heavy-duty wheeled chassis with torsion bar suspension features an integrated parking brake and towbar coupling for safe towing by commercial utility vehicles.

A water-cooled industrial diesel engine incorporates preheating elements for dependable cold-weather starting along with automated safety shutdowns for oil pressure and high coolant temperature.

A heavy steel acoustic hood with protective powder coating shields internal machinery against heavy rain, dust, and snow.

Multi-stage filtration mechanics and periodic maintenance intervals for compressor parts

To sustain air purity and prolong equipment operating life, OPA / OPPAIR compressed air systems require scheduled replacement of consumable filters and fluids.

Air intake filter elements and spin-on oil filter cartridges are replaced every 2000 operating hours or upon reaching maximum differential pressure limits on the indicator gauge.

The internal or spin-on air-oil separator element is scheduled for renewal every 3000 to 4000 operating hours in conjunction with synthetic compressor fluid replacement.

Periodic condensate drain inspection and radiator cleaning maintain dryer dew point stability and prevent moisture ingress into downstream pneumatic actuators.
