EP-CM90BF Water-Lubricated Oil-Free Screw Air Compressor
The EP-CM90BF is a 90 kW fixed-frequency water-lubricated oil-free screw compressor delivering up to 16.30 m³/min at 0.8–1.25 MPa — an upper-large industrial model for automotive paint lines, large-scale breweries, high-volume standard bottle blowing, and central plant compressed air systems requiring Class 0 purity at 16+ m³/min.
EP-CM90BF | 90 kW Water-Lubricated Oil-Free Compressor — 16.30 m³/min for Large Industrial Plants
At the 90 kW level, compressed air becomes a central plant utility rather than a workshop service. Automotive assembly plants, large-scale breweries, high-volume container filling facilities, and multi-process industrial complexes at this scale have compressed air demands that must be met continuously, at consistent quality, across production shifts that may run 24 hours a day. The compressor serving this demand is not a peripheral piece of equipment — it is a critical production utility, and its performance characteristics determine the ceiling of what the production facility can reliably produce.
The EP-CM90BF provides the capacity for this role from a water-lubricated single-screw platform that has never introduced oil into its compression circuit. At 90 kW (125 HP) with a peak free air delivery of 16.30 m³/min (576 cfm) at 0.8 MPa, it covers the volume requirements of large automotive paint line installations, major brewery utilities, and high-volume standard compressed air systems — with ISO 8573-1 Class 0 structural oil-free guarantee maintained across the full 0.8–1.25 MPa pressure range and 25-year design service life. For large facility managers evaluating central compressed air infrastructure, the Ever Power engineering team provides complete system design support.

Automotive Paint Lines: 16 m³/min of Defect-Free Spray Air
Automotive OEM body painting is one of the most technically demanding surface finishing processes in manufacturing. A defect-free clearcoat on a vehicle body requires spray air that is not only oil-free but consistently oil-free — across every spray gun cycle, every shift change, every ambient temperature variation, and every filter service interval. In an oil-injected compressed air system, none of these moments is guaranteed; each is a potential contamination event that depends on the current condition of a degradable filter element.
The EP-CM90BF eliminates this uncertainty by design. Water is the only substance in its compression circuit. There is no oil that can degrade, no filter that can be bypassed, and no temperature-dependent desorption mechanism that can release contamination into the spray air between maintenance intervals. For automotive paint line operators who have experienced the production economics of a fish-eye defect batch — strip, clean, re-prime, re-coat, re-inspect — the structural oil-free guarantee represents a risk elimination that justifies the technology on financial terms alone.
Key Features
16.30 m³/min — Central Plant Utility Volume
At 16.30 m³/min (576 cfm) peak FAD, the EP-CM90BF serves as the central compressed air source for large automotive paint facilities with four to five spray booths, major brewery utilities with simultaneous canning and kegging lines, or large industrial plants supplying multiple process areas from a single compressor.
Water-Cooled and Air-Cooled at 90 kW
The water-cooled model (3900 kg, 3750×1850×2180 mm) connects to a cooling tower for large industrial plant installations. The air-cooled variant (2160 kg, 2500×1400×1580 mm) is significantly lighter and more compact — suitable for facilities without cooling water infrastructure. Both variants achieve the same 16.30 m³/min FAD and ISO 8573-1 Class 0 air quality.
73 dB(A) at 90 kW — Industrial-Grade Acoustic Control
The single-screw direct-drive architecture maintains 73 dB(A) at 90 kW — a noise level that competes with much smaller conventional compressors. For automotive and brewery facilities where compressor noise has historically been a working environment complaint, the EP-CM90BF's acoustic performance represents a meaningful improvement alongside its capacity and quality advantages.
Isothermal Compression at 90 kW Scale
The specific power advantage of isothermal compression at 90 kW represents approximately 72,000 kWh of annual electricity saving at 8,000 operating hours — the highest absolute energy saving of any single CMB series model in the small-to-mid range. This saving applies from the first day of operation and is inherent to the thermodynamics of water-lubricated compression, requiring no additional equipment or operational adjustment.
Stainless Steel Throughout — Brewery and Food Grade
All surfaces in contact with compressed air — compression chamber, water separation barrel, internal piping, and discharge connections — are stainless steel. For brewery applications where compressed air may contact beer, cleaning solutions, or product packaging at various process points, the all-stainless-steel construction meets food and beverage contact material requirements.
485 Interface for Energy Management Integration
Real-time operating data output via 485 communication supports integration with factory energy management systems, production monitoring platforms, and automated demand response programmes. For large facilities operating energy management systems under ISO 50001, compressor operating data can be incorporated into energy consumption monitoring and target-setting frameworks.
Customer Case Studies
Germany — Tier-1 Automotive Body Paint Facility
Industry: Automotive Manufacturing | Application: Central oil-free compressed air for five simultaneous spray booths on a body-in-white coating line
"Fish-eye defect rate on our clearcoat line had been running at 0.3% — low by industry standards but representing significant rework cost on our production volume. Root cause analysis identified periodic oil carryover spikes from our filter train as a contributing factor. The EP-CM90BF replaced the oil-injected system with structural Class 0 oil-free air from one machine. Clearcoat fish-eye rate attributable to air quality: zero in 18 months."
★★★★★
Belgium — Large Craft and Premium Lager Brewery
Industry: Beer Production | Application: FSSC 22000-compliant Class 0 oil-free air for keg washing, canning line, and automated packaging
"FSSC 22000 certification audit requires structural oil-free documentation for all process air points. The EP-CM90BF's TUV Class 0 certificate satisfied our auditor's evidence requirements immediately. At 16.30 m³/min, it supplies our complete packaging hall — keg washer, canning line, labeller, and palletiser pneumatics — simultaneously. Our previous installation required two separate compressors for the same coverage."
★★★★★
Australia — Multi-Category Container Filling Facility
Industry: Packaging | Application: Oil-free central compressed air for filling lines across juice, milk, and condiment product categories
"Our facility runs six filling lines across three product categories with different hygiene requirements. The EP-CM90BF's 16.30 m³/min output covers all six lines simultaneously from one water-lubricated machine. FSANZ food safety certification required Class 0 oil-free documentation — one TUV certificate from Ever Power covered all six lines at once. Maintenance workload has dropped dramatically: one machine, one annual service event, versus the four-unit bank we previously operated."
