OPPAIR Equipment Portfolio and Technical Specifications
Explore the complete portfolio of OPPAIR permanent magnet inverter compressors, integrated laser cutting workstations, two-stage high pressure units, oil-free systems, and compressed air dryers with detailed engineering specifications.
OPPAIR PM VSD Permanent Magnet Inverter Screw Air Compressors
The energy-efficient OPPAIR PM VSD permanent magnet variable frequency screw air compressors are engineered for uninterrupted industrial compressed air supply. Integrating ultra-premium IE4/IE5 permanent magnet synchronous motors with advanced digital inverters, the system continuously modulates rotational rotor speed and volumetric air output from 25% to 100% in exact alignment with real-time pneumatic demand. This completely eliminates wasteful unloaded idling cycles and delivers electrical power savings of up to 35–40% compared to conventional fixed-speed machines. The direct-coupled drive design eliminates belt slippage and mechanical friction losses while maintaining stable line pressure within a stringent tolerance of ±0.01 MPa. Equipped with high-precision asymmetric rotary screw air ends and heavy-duty filtration, these units deliver exceptional operational reliability across heavy industrial environments.
Power 7.5–250 kW, pressure 7–16 bar, IE4/IE5 motors, 35–40% energy saving.
OPPAIR 4-in-1 and 5-in-1 Integrated Laser Cutting Screw Air Compressor Workstations
The OPPAIR 4-in-1 and 5-in-1 integrated laser cutting compressor workstations are purpose-built to supply high-purity pressurized air for fiber laser cutting machinery ranging from 1 kW to 30 kW. Engineered as a heavy-duty single-chassis package, each station incorporates a 16-bar high-pressure screw compressor (with custom options up to 20–30 bar), an integrated refrigerated air dryer achieving a pressure dew point of +2...+10 °C, a 300–600 L air receiver vessel, and a 4-stage precision filtration cascade. The system filters airborne particulates down to 0.01 μm and limits residual oil aerosol below 0.001 mg/m³, preventing contamination of optical focusing lenses and guaranteeing burr-free, oxidation-resistant cut edges on carbon steel, stainless steel, and aluminum alloys.
Pressure 16 bar, integrated dryer + 300–600 L tank + 4 filters 0.01 μm.
OPPAIR Two-Stage High Pressure Rotary Screw Air Compressors
The OPPAIR Two-Stage High Pressure rotary screw air compressors are engineered for continuous 24/7 heavy-duty operation in metallurgy, mining, chemical processing, and industrial manufacturing plants. Featuring two tandem screw air ends with intermediate oil-spray cooling, the compression ratio across each individual stage is significantly minimized. This intermediate cooling drastically reduces internal air leakage across rotor clearances, mitigates thermal expansion stress, and decreases bearing loads, extending air end service life up to 100,000 operational hours while delivering a 15% improvement in volumetric compression efficiency. The series offers pressure configurations of 3–5 bar, 8–15 bar, and 20–30 bar with motor capacities up to 315 kW.
Pressure 3–5 / 8–15 / 20–30 bar, power to 315 kW, two-stage compression.
OPPAIR ISO Class 0 Oil-Free Water Lubricated and Scroll Air Compressors
OPPAIR oil-free water-lubricated screw compressors and scroll compressor units provide zero-emission, 100% oil-free compressed air certified strictly to ISO 8573-1 Class 0 standards. In the water-lubricated screw architecture, purified deionized water serves as the natural lubricant and cooling medium, circulating through precision stainless steel rotors with ceramic composite coatings. Operating at low isothermal compression temperatures below +50 °C, the system eliminates thermal hydrocarbon cracking and varnish buildup. Scroll compressor modules utilize precision PTFE tip seals for ultra-silent, vibration-free operation. These systems serve as the ideal clean air solution for pharmaceutical compounding, medical facilities, semiconductor fabrication, and food processing lines.
ISO Class 0 certified, water lubricated, stainless rotors, temp <50 °C.
OPPAIR Heavy-Duty Skid-Mounted Packaged Air Compressor Stations
OPPAIR Skid-Mounted packaged compressor stations are heavy-duty, factory-tested modular pneumatic plants assembled upon a rigid structural steel skid. Integrating a high-pressure rotary screw compressor, an air dryer (refrigerated +3 °C or desiccant adsorption -40 °C dew point), a cyclone moisture separator, an ASME-rated vertical air receiver, and multi-stage coalescing filters, the entire unit functions as an autonomous plug-and-play air system. Featuring built-in vibration isolators and forklift transport pockets, these skid assemblies allow industrial facilities to deploy dedicated high-pressure air supplies rapidly without costly facility modifications or complex piping installations.
Single rigid skid, dew point to -40 °C, rapid plug & play deployment.
OPPAIR 30–40 Bar High-Pressure PET Bottle Blowing Compressors and Boosters
The OPPAIR 30–40 bar high-pressure compressors and reciprocating booster stations are engineered specifically for high-volume blow molding of PET containers, bottles, and jars, as well as high-pressure hydro-pneumatic proof testing. The system utilizes an efficient hybrid architecture: an initial rotary screw stage compresses atmospheric air to 8–10 bar, followed by a heavy-duty reciprocating booster that elevates final pressure to 30 or 40 bar. Incorporating Swedish alloy steel reed valves, plateau-honed cast iron cylinder liners, and multi-stage intercoolers with condensate separators, these stations ensure superior thermodynamic stability and continuous 24/7 reliability in automated packaging plants.
Pressure 30–40 bar, hybrid screw + booster setup, Swedish steel valves.
OPPAIR Compressed Air Treatment: Twin Tower Desiccant Dryers and Filters
The OPPAIR compressed air treatment portfolio encompasses twin-tower heatless and heated desiccant dryers, modular adsorption dryers, high-capacity refrigerated dryers, and multi-stage inline particulate filters. The twin-tower desiccant systems utilize premium activated alumina and molecular sieve desiccants to achieve ultra-dry pressure dew points ranging from -40 °C down to -70 °C, preventing freezing and condensation in sub-zero ambient conditions. Coalescing inline filters (C-grade 3 μm, T-grade 1 μm, A-grade 0.01 μm, and F-grade activated carbon) eliminate oil vapors and solid debris, protecting pneumatic actuators, valves, and analytical instrumentation.
Dew point -40...-70 °C, twin-tower desiccant, C/T/A/F filters 0.01 μm.
