EP-CM75BF Water-Lubricated Oil-Free Screw Air Compressor
The EP-CM75BF is a 75 kW fixed-frequency water-lubricated oil-free screw compressor delivering up to 12.90 m³/min at 0.8–1.25 MPa — a large-scale industrial model for semiconductor fabrication utilities, large pharmaceutical plants, continuous chemical reactor complexes, and high-volume process facilities where Class 0 purity at 12+ m³/min is the baseline requirement.
EP-CM75BF | 75 kW Water-Lubricated Oil-Free Compressor — 12.90 m³/min for Large Process Facilities
At the 75 kW power class, compressed air technology selection decisions carry facility-level consequences. A semiconductor fab, a large pharmaceutical manufacturing floor, or a continuous chemical reactor complex is not a collection of workstations — it is a production system where compressed air is a utility with plant-wide dependencies. When the compressor performs reliably, everything downstream operates as planned. When it fails, or when its air quality is compromised, the production consequences extend across entire manufacturing floors, entire product batches, and in safety-critical environments, potentially beyond the production facility itself.
The EP-CM75BF is built for this operating context. At 75 kW (100 HP) with a peak free air delivery of 12.90 m³/min (455 cfm) at 0.8 MPa, it delivers large-plant-scale output with the water-lubricated single-screw platform's structural reliability and structural ISO 8573-1 Class 0 oil-free guarantee. A noise level of 73 dB(A) reflects the scale of the machine while remaining within industrial plant acoustic norms. For semiconductor utilities, pharmaceutical manufacturing utilities, and chemical process plants requiring 10+ m³/min of guaranteed Class 0 oil-free air, the EP-CM75BF provides the capacity from a single unit with one maintenance programme.

Semiconductor Fab Utility: 12.90 m³/min of Zero-Contamination Process Air
Semiconductor fabrication compressed air utilities must sustain Class 0 oil-free air quality continuously across 24/7 production cycles where any contamination event is measured in wafer yield loss and tool qualification downtime. The EP-CM75BF's structural oil-free guarantee — water lubrication has never contained oil — provides the immutable quality baseline that semiconductor utility qualification requires. There is no filter degradation mechanism, no filter bypass risk, and no temperature-dependent desorption event that can introduce oil contamination between maintenance intervals. Quality is consistent on day 1 and day 9,000 of operation.
The all-stainless-steel internal air path — from the 1 μm intake filter through the compression chamber, separation barrel, and discharge connections — eliminates metallic particle generation from rust or scale, meeting the ISO Class 1 particulate requirements of semiconductor process tool inlet specifications alongside the Class 0 oil content requirements.
Key Features
12.90 m³/min — Large Plant Utility Scale
At 12.90 m³/min (455 cfm) peak FAD at 0.8 MPa, the EP-CM75BF serves as the central compressed air source for large semiconductor equipment sections, complete pharmaceutical manufacturing floors, or major chemical process units — delivering the volume required for plant-level utility service from a single water-lubricated machine.
Structural Class 0 for Continuous 24/7 Processes
The water lubrication mechanism maintains structural Class 0 oil-free status throughout 24/7 continuous operation with no degradation mechanism. For continuous process facilities where scheduled maintenance windows are infrequent, this structural rather than filter-dependent oil-free guarantee provides the consistent quality baseline that process qualification and safety documentation require.
73 dB(A) at 75 kW Large Industrial Output
The acoustic engineering of the single-screw water-lubricated platform — direct motor drive, no gears, smooth orbital compression — maintains 73 dB(A) at 75 kW output. For semiconductor and pharmaceutical facility utility areas with acoustic requirements driven by cleanroom or GMP zone proximity, this noise level is compatible with standard plant room construction.
Isothermal Efficiency at 75 kW Scale
At 75 kW and 8,000 annual operating hours, the isothermal compression advantage represents approximately 60,000 kWh of annual electricity saving versus dry adiabatic alternatives. This scale of annual energy cost reduction makes the water-lubricated technology investment case compelling even at the single-unit level, before multi-unit station efficiency gains are considered.
Energy Efficiency Station Integration
Multiple EP-CM75BF units can be coordinated in an AI-optimised central compressed air station that automatically manages compressor staging, rotation, and demand response across all units. This station approach provides full-capacity redundancy and demand-tracking efficiency for large continuous process facilities that cannot accept single-unit supply risk.
25-Year Air End Design Life — Capital Asset Longevity
At 75 kW and large-plant-utility scale, the economic value of the 25-year air end design life is most clearly expressed. A single air end replacement in a 75 kW compressor represents a significant capital expenditure. The water-lubricated single-screw design — balanced radial loads, low rotational speed, aviation-grade star wheel materials — is engineered to make this replacement unnecessary within the normal planning horizon of large industrial facilities.
Customer Case Studies
Japan — Semiconductor Equipment Manufacturer
Industry: Semiconductor Manufacturing Equipment | Application: Process utility air for manufacturing and testing semiconductor fabrication equipment before delivery to fabs
"We manufacture and test semiconductor fab equipment before delivery. Our testing environment requires Class 0 oil-free compressed air at the same quality as the customer fab environment. The EP-CM75BF's structural Class 0 guarantee and all-stainless-steel air path satisfied our customer's incoming qualification requirements without additional testing. The 12.90 m³/min output is sufficient for our full equipment test floor operating simultaneously."
★★★★★
Switzerland — Large Pharmaceutical Manufacturing Plant
Industry: Pharmaceutical Manufacturing | Application: GMP process air for sterile manufacturing suites, tablet compression areas, and lyophilisation
"Our Swissmedic GMP authorisation requires documented Class 0 structural oil-free compressed air for all process air contact points. The EP-CM75BF's TUV structural certification provided the primary validation evidence document. The 12.90 m³/min output serves our entire sterile manufacturing floor with margin. The water-lubricated design also produces no oil-contaminated condensate — simplifying our environmental compliance obligations significantly."
★★★★★
Saudi Arabia — Petrochemical Complex Utilities
Industry: Petrochemical Processing | Application: Instrument air and utility air for continuous process control in a large petrochemical facility
"Operating at 45°C ambient, our utility air system required a compressor design that would perform consistently in extreme heat without efficiency derating. The EP-CM75BF's water lubrication maintains isothermal compression at ambient +15°C regardless of external temperature — 60°C chamber temperature versus 220°C in dry alternatives. No efficiency derating, no accelerated rotor wear from thermal expansion. Two years in, performance is unchanged from commissioning."
