EP-CM200B Water-Lubricated Oil-Free Screw Air Compressor
The EP-CM200B is a 200 kW water-lubricated oil-free screw compressor delivering up to 36.63 m³/min at 0.8–1.25 MPa — a very large industrial unit for steel and metal production utilities, airport compressed air systems, large port facilities, and major industrial central stations where Class 0 oil-free air is required at 36+ m³/min scale.
EP-CM200B | 200 kW Water-Lubricated Oil-Free Compressor — 36.63 m³/min for Very Large Industrial Utilities
At 200 kW, the compressed air output from a single compressor unit reaches volumes that, in earlier industrial eras, required compressor houses with multiple machines. The EP-CM200B delivers 36.63 m³/min — more than a thousand cubic feet per minute of structural Class 0 oil-free compressed air — from a single water-lubricated single-screw unit that requires no oil changes, no oil separators, no inter-stage cooling, and produces no oil-contaminated condensate. For very large industrial utilities, the EP-CM200B represents a step change in operational simplicity at a scale where simplicity has the most impact.
Steel and metals production facilities, airport ground operations, large port compressed air systems, and major continuous process plants all sit in the operational territory that the EP-CM200B addresses. At 200 kW (270 HP) with peak output of 36.63 m³/min (1,293 cfm) at 0.8 MPa and ISO 8573-1 Class 0 structural oil-free guarantee, it provides very large industrial utility capacity with the water-lubricated platform's inherent advantages: isothermal energy efficiency, 25-year air end design life, and zero oil in the compressed air supply chain by construction.

Airport and Port Applications: Central Compressed Air at Infrastructure Scale
Modern airports and container ports operate compressed air systems that supply pneumatic equipment across large geographic areas — boarding bridge actuators, gate control systems, crane hydraulic backup, container inspection tools, and maintenance workshop equipment may all draw from a single central compressed air station. At this infrastructure scale, a compressor failure affects multiple simultaneous operations, and air quality failures have consequences across the entire facility. The central compressor must therefore be both highly reliable and consistently high-quality.
The EP-CM200B's structural Class 0 oil-free guarantee eliminates air quality failure as a variable. Its single-screw water-lubricated architecture has fewer moving parts than multi-stage alternatives — seven bearings versus fifteen or more in dry twin-screw designs — with correspondingly fewer mechanical failure modes. The 25-year design service life aligns with infrastructure asset planning horizons. And the 36.63 m³/min output from a single unit simplifies the compressed air station design, reducing the number of machines, the number of control systems, and the maintenance overhead to their minimum.
Key Features
36.63 m³/min — Very Large Industrial Utility Output
At 36.63 m³/min (1,293 cfm), the EP-CM200B covers the compressed air demand of very large industrial facilities — major automotive plants, airport central systems, port facilities — from a single unit. This volume reduces the number of compressors required in central stations, simplifying infrastructure, reducing maintenance complexity, and lowering the total capital investment in compressed air equipment.
200 kW Isothermal Efficiency — Maximum Annual Saving
At 200 kW and 8,000 annual operating hours, the isothermal compression advantage represents approximately 160,000 kWh of annual electricity saving versus dry adiabatic alternatives — the highest absolute annual energy saving of any fixed-frequency CMB series model. For large industrial facilities where compressed air electricity accounts for 30–40% of total site energy cost, this saving is a major contributor to overall site energy performance.
Structural Class 0 at Infrastructure Scale
When one compressor supplies an entire large facility, the consequences of a quality failure are facility-wide. The structural Class 0 guarantee of water lubrication — no oil in the compression circuit at any point — eliminates oil contamination as a risk across all downstream users simultaneously. This infrastructure-scale quality guarantee is qualitatively different from filter-dependent systems where one filter failure affects every user downstream.
Single-Stage 1.25 MPa Capability
Single-stage compression to 1.25 MPa eliminates the multi-stage intercooler infrastructure required by dry oil-free alternatives to reach this pressure. For large industrial facilities that need higher-pressure compressed air for specific applications, the EP-CM200B provides it from the same machine that supplies standard-pressure users — one machine, one pressure range, full output flexibility.
Aviation-Grade Star Wheel Longevity
The star wheel blades — the compression contact elements that mesh with the main screw — are manufactured from aviation-grade composite materials developed specifically to solve the wear challenge at the screw-star wheel interface. At 200 kW operating conditions, the longevity of these components determines the air end's sustained performance across the 25-year design life. Aviation-grade materials and strict pre-installation screening ensure service life consistent with the design specification.
Zero Contaminated Condensate — Infrastructure Environmental Compliance
At airport, port, and large industrial facility scale, environmental compliance obligations around compressed air condensate disposal are amplified. The EP-CM200B produces no oil-contaminated condensate — zero hazardous waste is generated by the compressor itself. For facilities operating under ISO 14001 environmental management or subject to environmental discharge monitoring, this elimination of an entire waste stream is a material compliance simplification.
Customer Case Studies
Japan — Large Automotive Stamping and Welding Plant
Industry: Automotive Manufacturing | Application: Central compressed air for press shop, body welding, and surface treatment across a large automotive body manufacturing facility
"Our body plant requires 32 m³/min of Class 0 oil-free compressed air across press shop, body welding, and electrocoat surface treatment simultaneously. The EP-CM200B at 36.63 m³/min covers all three areas with capacity for future expansion. Replacing our previous six-compressor installation with a single unit has reduced our annual maintenance labour by 78% and eliminated the coordination overhead of managing six service schedules."
★★★★★
UAE — Major International Airport
Industry: Airport Operations | Application: Central compressed air for boarding bridges, gate control systems, and apron maintenance workshops across a major hub airport
"Airport infrastructure must be reliable 24/7, 365 days. The EP-CM200B was selected because it has fewer mechanical components than any other 200 kW class compressor we evaluated — fewer failure modes, longer service intervals, and no mid-life capital events from rotor coating replacement. In 22 months of operation, uptime has been 99.97%. The structural Class 0 certification also satisfies our airport quality management system requirements for compressed air used in boarding bridge hydraulic backup systems."
★★★★★
Brazil — Large Container Port Facility
Industry: Port Operations | Application: Central compressed air for container crane hydraulic systems, quay equipment, and maintenance workshops
"Port compressed air systems must handle highly variable demand — crane cycles create large instantaneous demand spikes. The EP-CM200B with an appropriately sized receiver handles our crane cycle demand profiles with stable pressure throughout. The air-cooled installation in our open equipment building has been straightforward — no cooling water infrastructure required. We also value the zero oil condensate output: our port environmental licence prohibits discharge of oil-contaminated water to any drain system."
