EP-CM110BF | 110 kW Fixed-Frequency Water-Lubricated Oil-Free Compressor — 19.40 m³/min

The 110 kW power class marks the upper boundary of the fixed-frequency single-motor CMB series — the point at which water-lubricated single-screw technology delivers its highest single-unit output in a fixed-speed configuration. For semiconductor fab central utilities, pharmaceutical API bulk production facilities, and large continuous process plants where compressed air demand is stable and sustained at 15–20 m³/min throughout production operations, the EP-CM110BF provides the capacity that eliminates multi-unit coordination complexity while maintaining the structural Class 0 oil-free guarantee across the full 25-year design service life.

At 110 kW (150 HP) with a peak free air delivery of 19.40 m³/min (685 cfm) at 0.8 MPa, the EP-CM110BF is the single-motor fixed-frequency flagship of the CMB water-lubricated series. Its ISO 8573-1 Class 0 structural oil-free guarantee, single-stage 1.25 MPa capability, 76 dB(A) noise level, and 25-year air end design life make it the definitive fixed-frequency water-lubricated compressor for large-scale industrial applications requiring maximum output simplicity.

Maximum Fixed-Frequency Output: 19.40 m³/min from One Water-Lubricated Machine

The case for fixed-frequency rather than variable-speed technology at 110 kW rests on the operational profile of large continuous process facilities. Semiconductor fab central utilities, pharmaceutical API reactors, and continuous chemical process plants typically operate at stable, near-constant compressed air demand throughout their production cycles — the demand variation that justifies VSD investment in multi-format production environments is not present in the same measure at continuous process plants running on fixed production programmes.

For these applications, the mechanical simplicity of a fixed-frequency single-motor design is a direct advantage: no inverter drive components to maintain, no VSD control logic to calibrate, and no variable speed operation to monitor. The EP-CM110BF delivers its rated 19.40 m³/min whenever it is running — consistent, predictable, and simple to integrate into a fixed compressed air system design. The structural Class 0 oil-free guarantee and 25-year air end life are identical to the VSD models; the difference is in operational simplicity, not air quality or longevity.

Key Features

19.40 m³/min — Fixed-Frequency Series Maximum

The EP-CM110BF delivers the highest fixed-frequency single-motor output in the CMB water-lubricated series. At 19.40 m³/min (685 cfm), it serves as the central compressed air source for large semiconductor fab sections, complete pharmaceutical API floors, or major continuous chemical process units from a single machine with fixed-speed operational simplicity.

110 kW Permanent Magnet Motor — IE4 Efficiency

The 110 kW direct-drive permanent magnet motor operates at IE4 efficiency class — 3–5% higher than standard asynchronous motors — delivering maximum shaft power to the air end with minimum electrical loss. Combined with isothermal compression, this motor efficiency advantage compounds to deliver the lowest specific power consumption (kW per m³/min) available at this output level in fixed-frequency water-lubricated technology.

Water-Cooled or Air-Cooled Configuration

The water-cooled variant (4000 kg, 3750×1850×2180 mm) is standard for large industrial installations with cooling tower infrastructure. The air-cooled variant (2270 kg, 2500×1400×1580 mm) serves facilities without cooling water — its significantly lower weight and smaller footprint make it the preferred choice for facilities with limited equipment room space or floor loading capacity.

76 dB(A) at 110 kW Large-Scale Output

At 110 kW, the single-screw water-lubricated platform maintains 76 dB(A) — a noise level that, at this power class, is notably lower than dry oil-free twin-screw alternatives and dramatically lower than piston compressors of equivalent output. For pharmaceutical facilities with GMP acoustic requirements in cleanroom-adjacent utility areas, 76 dB(A) is achievable within standard plant room construction.

Consolidation of Five to Seven Smaller Units

The EP-CM110BF's 19.40 m³/min output is equivalent to the combined output of five to seven 30 kW class compressors. Consolidation to a single EP-CM110BF reduces compressor room complexity, maintenance labour, spare parts inventory, and the coordination overhead of managing multiple unit service schedules — delivering total cost of ownership savings that typically exceed the investment in the 110 kW unit within three to five years.

Full CMB Series Upgrade Path

The EP-CM110BF sits at the top of the CMB fixed-frequency series and is fully technology-compatible with the VSD models that follow. Facilities that install an EP-CM110BF and subsequently require variable-speed capability for energy optimisation can add VSD units to a central compressed air station configuration without changing their downstream treatment infrastructure or compressed air distribution network.

Customer Case Studies

South Korea — Semiconductor Component Manufacturer

Industry: Semiconductor Manufacturing  |  Application: Central utility compressed air for a 200mm wafer fab producing MEMS devices

"Our fab central utility specification required Class 0 oil-free air at 18+ m³/min continuously. The EP-CM110BF was the only single-unit water-lubricated option that met this volume requirement in fixed-frequency configuration. After 24 months of continuous operation, the structural Class 0 air quality has never been challenged in a quarterly air quality test. The fixed-frequency design also simplified our utility automation — predictable constant output is easier to integrate than VSD modulation for our fixed-demand production programme."

★★★★★

Ireland — Large API Pharmaceutical Plant

Industry: Pharmaceutical API Manufacturing  |  Application: GMP process air for multi-reactor API synthesis, spray drying, and granulation

"Our GMP authorisation requires structural oil-free compressed air at all API process contact points. The EP-CM110BF's 19.40 m³/min output covers our complete API manufacturing floor simultaneously — five reactors, two spray dryers, and granulation equipment. TUV Class 0 certification was accepted by our HPRA inspector as primary validation evidence without additional sampling requirements. Zero GMP deviations related to compressed air quality in 20 months."

★★★★★

United States — Specialty Chemical Continuous Process Plant

Industry: Specialty Chemicals  |  Application: Instrument air and process purge air for a 24/7 continuous chemical production facility

"Our continuous process runs 24/7 with scheduled turnarounds only every 18 months. The EP-CM110BF's 25-year air end design life and structural Class 0 guarantee were the two criteria that determined the specification. Fixed-frequency operation matches our constant demand profile exactly — no VSD cycling, consistent pressure, predictable load on our electrical supply. In 28 months of operation, we have not had a single compressed air quality excursion."

Frequently Asked Questions

What is the highest single-motor fixed-frequency output in the CMB series?
The EP-CM110BF delivers 19.40 m³/min at 0.8 MPa — the highest single-motor fixed-frequency output in the CMB series before the series steps into the variable-frequency configurations. At 110 kW, it provides the maximum fixed-speed simplicity available in the water-lubricated single-screw product family, making it the preferred choice for large continuous process facilities where demand is stable and VSD complexity is not warranted.
How does the EP-CM110BF serve semiconductor fab central utilities?
A semiconductor fab central utility station supplying an entire production floor typically requires 15–25 m³/min of Class 0 oil-free compressed air at 0.7–0.8 MPa. The EP-CM110BF at 19.40 m³/min covers this range from a single unit for medium-size fab facilities, or operates as one unit in a multi-compressor station for larger fabs. The all-stainless-steel internal air path meets the particulate and oil-content requirements of semiconductor tool specifications at the source.
What is the significance of 19.40 m³/min in pharmaceutical API production?
Large pharmaceutical API (active pharmaceutical ingredient) production facilities use compressed air for pneumatic reactors, spray dryers, fluid bed granulators, and sterile fill-finish equipment — collectively consuming 15–20 m³/min at 0.6–0.8 MPa in large facilities. The EP-CM110BF covers this demand range from a single machine, providing the structural Class 0 oil-free air required for GMP compliance at every process air contact point.
Can the EP-CM110BF replace an entire bank of 22 kW or 30 kW compressors?
Yes. The EP-CM110BF's 19.40 m³/min output is equivalent to the combined output of five to seven EP-CM30BF units. Consolidating a bank of smaller compressors into a single EP-CM110BF delivers: one control system instead of five to seven, one maintenance schedule instead of five to seven, one parts inventory instead of five to seven, and a significant reduction in compressor room floor space. Total cost of ownership over five years typically favours consolidation.
What are the installation requirements for the EP-CM110BF?
The water-cooled EP-CM110BF weighs 4000 kg and has a footprint of 3750×1850 mm. A reinforced floor with anti-vibration mounts is recommended. The air-cooled variant weighs 2270 kg with a 2500×1400 mm footprint — significantly more manageable for facilities without heavy equipment handling infrastructure. Both variants require adequate ventilation for heat dissipation from the motor and compression system.
