EP-CM132BF Water-Lubricated Oil-Free Screw Air Compressor
The EP-CM132BF is a 132 kW fixed-frequency water-lubricated oil-free screw compressor delivering up to 22.21 m³/min at 0.8–1.25 MPa — a high-capacity unit for EV battery manufacturing facilities, hydrogen fuel cell production lines, large electronics fabrication plants, and heavy continuous industrial processes requiring 22+ m³/min of structural Class 0 oil-free air.
EP-CM132BF | 132 kW Water-Lubricated Oil-Free Compressor — 22.21 m³/min for Next-Generation Manufacturing
The emergence of large-scale EV battery manufacturing, hydrogen fuel cell production, and advanced semiconductor packaging has created a new category of compressed air demand — one where the volume requirements of a major production facility must be met with the strictest possible air purity standard, and where contamination consequences extend beyond product quality into product safety and long-term reliability. EV battery cells with oil-contaminated electrodes lose capacity faster. Hydrogen fuel cells with oil traces in catalyst layers produce less power and degrade more quickly. In these next-generation manufacturing contexts, the structural oil-free guarantee of water-lubricated compression is not a quality preference — it is a production engineering requirement.
The EP-CM132BF addresses this requirement at 132 kW scale. Delivering 22.21 m³/min (784 cfm) of ISO 8573-1 Class 0 oil-free compressed air at pressures up to 1.25 MPa, it provides the high-volume output required for large EV battery manufacturing sections, fuel cell MEA production environments, and advanced electronics fabrication utilities — with the water-lubricated single-screw platform's structural oil-free guarantee, 25-year air end design life, and isothermal energy efficiency that make it the appropriate technology for facilities with 25-year production planning horizons.

EV Battery Manufacturing: Where Structural Oil-Free Air Is a Cell Safety Requirement
Lithium-ion battery cell manufacturing imposes compressed air quality requirements that exceed those of most conventional industrial applications. The electrode coating process — applying cathode and anode slurries to metallic foil substrates at high precision — uses compressed air for coating width control, tension management, and dry room pressurisation. Any oil contamination of the electrode coating environment can embed oil traces in the finished electrode, creating local impedance variations that accelerate capacity fade and, in severe cases, create lithium plating conditions that are a fire and explosion risk.
The electrolyte filling process is equally sensitive. Lithium-ion electrolytes are reactive with organic contaminants including lubricating oil. Oil contamination of the filling environment or the compressed air used in the filling equipment can alter electrolyte composition, affect SEI (solid electrolyte interphase) formation on the anode, and reduce the cell's safe operating envelope. The EP-CM132BF's water-lubricated structural Class 0 oil-free air supply eliminates these risks at the source — there is no oil in the compression circuit that can migrate into the manufacturing environment under any operating condition.
Key Features
22.21 m³/min — Gigafactory Utility Scale
At 22.21 m³/min (784 cfm) peak FAD at 0.8 MPa, the EP-CM132BF serves as the compressed air utility source for large EV battery electrode coating sections, complete fuel cell MEA production floors, or major advanced electronics fabrication areas — delivering next-generation manufacturing utility capacity from a single water-lubricated machine.
Structural Class 0 for Safety-Critical Manufacturing
Water lubrication produces no oil that can enter the compressed air stream under any operating condition. This structural guarantee — not dependent on filter condition, maintenance compliance, or operating temperature — provides the immutable air quality baseline required for safety-critical manufacturing processes where oil contamination has consequences beyond product quality rejection.
78 dB(A) at 132 kW
The single-screw direct-drive water-lubricated platform maintains 78 dB(A) at 132 kW — significantly lower than dry oil-free twin-screw alternatives at equivalent output. For EV battery and fuel cell manufacturing facilities with cleanroom-adjacent utility areas, 78 dB(A) is compatible with standard technical services acoustic standards.
Isothermal Efficiency at 132 kW Scale
At 132 kW and 8,000 annual operating hours, the isothermal compression advantage represents approximately 106,000 kWh of annual electricity saving versus dry adiabatic alternatives — the largest absolute saving of any fixed-frequency CMB series model in the 100 kW range. For gigafactory utilities with multiple compressors, this advantage multiplies across every unit in the station.
All-Stainless-Steel Air Path — Zero Particle Risk
Every surface in the compressed air path — compression chamber, water separation barrel, internal piping, and discharge connections — is stainless steel. In EV battery and fuel cell manufacturing cleanrooms where particulate contamination of electrode surfaces is as damaging as oil contamination, the all-stainless-steel construction eliminates rust and scale particles from the compressed air supply alongside oil.
Multi-Unit Station Capability
Multiple EP-CM132BF units can be coordinated in an AI-optimised central compressed air station for gigafactory-scale utility demands. Automatic compressor staging, rotation scheduling, and demand response across multiple units provides full-capacity redundancy and demand-tracking efficiency for facilities where compressed air supply continuity is a production safety requirement.
Customer Case Studies
China (export market reference) — EV Battery Gigafactory
Industry: EV Battery Manufacturing | Application: Dry room pressurisation and electrode coating compressed air for large-format lithium-ion cell production
"Our gigafactory dry room requires compressed air with dew points below -60°C and Class 0 oil-free status at all times — oil contamination of the dry room environment would require full decontamination and recertification. The EP-CM132BF's structural Class 0 guarantee provides the oil-free basis our desiccant dryer system needs to achieve the target dew point without oil loading the desiccant bed prematurely. In 18 months of continuous operation, no oil-related dry room contamination events have occurred."

"PEM fuel cell catalyst layers are platinum-based — any oil contamination causes irreversible catalyst poisoning and permanent power loss in the finished stack. The EP-CM132BF's structural Class 0 water-lubricated air supply was specified precisely because it provides the only technology basis that is structurally free of oil contamination risk. Our fuel cell stack performance validation data shows consistent rated output across all units produced since installation."
