EP-CM30BF Water-Lubricated Oil-Free Screw Air Compressor
The EP-CM30BF is a 30 kW fixed-frequency water-lubricated oil-free screw compressor delivering up to 5.00 m³/min at 0.8–1.25 MPa — a high-volume single-unit solution for large food and beverage facilities, multi-line packaging plants, and industrial environments where production scale demands 5 m³/min of structural Class 0 oil-free compressed air from a single machine.
EP-CM30BF | 30 kW High-Volume Water-Lubricated Oil-Free Compressor — 5.00 m³/min
Large food production facilities, multi-line packaging plants, and high-volume industrial operations have a common compressed air infrastructure challenge: they need enough clean air to supply multiple simultaneous processes at sustained high consumption rates, and they need it from a system that is reliable enough to support continuous production, simple enough not to demand dedicated maintenance personnel, and clean enough to satisfy food safety, pharmaceutical, or industrial quality audits without extensive documentation overhead.
The EP-CM30BF is the highest-output fixed-frequency single-motor model in the CMB series below the 37 kW tier. At 30 kW (40 HP) with a peak free air delivery of 5.00 m³/min (177 cfm) at 0.8 MPa, it provides a single-unit answer to high-volume oil-free compressed air requirements that previously required two or more smaller machines in parallel. ISO 8573-1 Class 0 oil-free air quality is guaranteed structurally across all three pressure levels (0.8, 1.0, 1.25 MPa) and throughout the machine's 25+ year design service life. At 66 dB(A), it remains within production area noise norms without specialist acoustic treatment.

From Multi-Unit Complexity to Single-Machine Simplicity
A common infrastructure pattern in food and packaging facilities is the accretion of multiple smaller compressors over time — one unit added when production started, a second when the first line expanded, a third when a new product line was commissioned. This organic growth produces a compressor room with multiple units of different ages, different service schedules, and often different technologies, creating a coordination burden for maintenance teams and a reliability risk from the oldest units in the bank.
The EP-CM30BF's 5.00 m³/min output — equivalent to the combined output of three to four smaller units in the 7.5–15 kW range — enables facilities to consolidate this accumulated compressor infrastructure into a single machine with one control system, one maintenance schedule, and one set of service consumables. The resulting reduction in maintenance labour, spare parts inventory, and management overhead typically recovers the consolidation investment within two to three years.
Key Features
5.00 m³/min — Consolidation Capacity
At 5.00 m³/min (177 cfm), the EP-CM30BF replaces three to four smaller compressors in a single machine. Large food production facilities, multi-line packaging plants, and industrial laundries that have been running multiple units can consolidate to one machine, one control system, and one maintenance schedule — reducing complexity and long-term operational cost simultaneously.
Single-Stage 1.25 MPa Operation
Full working pressure range of 0.8 to 1.25 MPa achieved in a single compression stage — no intercoolers, no stage-boundary losses, no multi-stage valve assemblies. Facilities requiring different pressures for different processes can serve them from one machine by adjusting the PLC pressure setpoint, eliminating the need for separate compressors per pressure level.
30 kW Energy Efficiency via Isothermal Compression
At 30 kW, the 10%+ specific power advantage of isothermal compression versus adiabatic dry alternatives represents approximately 24,000 kWh of annual electricity saving at 8,000 operating hours. Over the 25-year design service life, this cumulative saving is substantial — and it is realised automatically in every operating hour without additional investment or operational adjustment.
66 dB(A) — Large Machine, Controlled Noise
Maintaining 66 dB(A) at 30 kW output requires the complete noise engineering package of the single-screw water-lubricated platform: direct-drive motor (no belt noise), no gear train (no gear mesh frequency), the smooth orbital compression cycle, and the CMN-patented acoustic intake structure with high-density soundproofing material. At 66 dB(A), hearing protection is not typically required for personnel working near the machine.
Dual Cooling — Water-Cooled and Air-Cooled
Both water-cooled (W) and air-cooled (F) variants are available. The water-cooled model connects to a facility cooling circuit or cooling tower for installations where cooling water is readily available. The air-cooled model is self-contained, requiring only electrical connection — suitable for facilities without cooling infrastructure or in regions where cooling water cost or availability is a constraint.
25-Year Air End Design Life
The stainless steel single-screw air end operates at approximately 3,000 rpm with balanced radial loads from the symmetrical star wheel arrangement. This low-speed, balanced-load operating condition is the structural basis for the 25-year design service life — a commitment that is reflected in the two-year air end warranty and supported by the isothermal operating temperature that prevents thermal fatigue throughout the service life.
Customer Case Studies
New Zealand — Large Dairy Processing Facility
Industry: Dairy Processing | Application: Food-grade process air for automated filling, capping, and packaging on four simultaneous dairy product lines
"MPI food safety requirements for our dairy facility mandate Class 0 oil-free compressed air at all product-contact process air points. Our previous system ran four separate 11 kW compressors — different ages, staggered service schedules, and one persistent oil carryover concern on the oldest unit. Consolidating to a single EP-CM30BF simplified everything: one service event per year, one TUV certificate for all four lines, and zero oil-related batch investigation in 22 months of operation."
★★★★★
Poland — Industrial Laundry Network
Industry: Industrial Laundry | Application: Oil-free compressed air for press ironers, automated folding systems, and garment tunnel finishers serving healthcare and hospitality clients
"Healthcare linen is zero-tolerance for oil contamination — a single oil-stained garment returned to a hospital client triggers a quality non-conformance. The EP-CM30BF supplies our entire laundry facility with Class 0 oil-free air from one machine. We have eliminated oil contamination as a quality risk entirely. The 5.00 m³/min output covers all three press ironers and the tunnel finisher simultaneously with margin."
★★★★★
South Africa — Multi-Category Packaging Co-Packer
Industry: Packaging | Application: Oil-free air for pneumatic conveying, sealing, and labelling across five product categories requiring different compressed air points
"We replaced three compressors of different ages and technologies with a single EP-CM30BF. The consolidation reduced our annual compressed air maintenance cost by more than 60%. The 5.00 m³/min output handles all five of our packaging lines simultaneously during peak production hours. The TUV Class 0 certification satisfies every one of our brand-owner clients' quality audit requirements — some of which were previously requiring us to submit separate filter maintenance records per audit."
