EP-CM45BF | 45 kW Water-Lubricated Oil-Free Compressor — 7.80 m³/min for Heavy Industrial Production

Glass container manufacturing, large food production plants, and industrial printing facilities sit at the boundary between mid-range and large-scale compressed air requirements. They need more volume than a 30 kW compressor can reliably supply across a full production shift, but they may not yet be at the scale where 75 kW class machines are warranted. The right compressor for this band is one that delivers genuine large-industrial output without demanding large-industrial installation infrastructure — and does so with the oil-free air quality that food safety, pharmaceutical packaging, and quality printing applications require as a baseline, not a premium.

The EP-CM45BF serves this demand precisely. At 45 kW (60 HP) with a peak free air delivery of 7.80 m³/min (275 cfm) at 0.8 MPa, it delivers the volume that large production environments need while maintaining the water-lubricated single-screw platform's structural ISO 8573-1 Class 0 oil-free guarantee and single-stage 1.25 MPa capability. At 68 dB(A), it remains within industrial area acoustic norms. For glass container producers, food manufacturers, and printing facilities stepping beyond the 30–37 kW range, the EP-CM45BF provides the capacity increment without a step change in installation complexity.

Glass Container Manufacturing: Why Forming Air Quality Defines Product Quality

In an IS (individual section) glass forming machine, compressed air performs direct mechanical work on the molten glass surface. Blank mould air cools and shapes the parison; finish air forms the neck and thread profile; section air controls the transfer mechanisms. The air contacts molten glass at 700–1,000°C — any oil in this air stream carbonises on contact with the hot glass surface, creating inclusions and surface defects that are visible in the finished container and potentially catastrophic for pharmaceutical glass that must pass optical inspection.

The EP-CM45BF delivers oil-free forming air that is guaranteed at the source — not filtered downstream from an oil-containing supply. This structural guarantee is particularly important in glass container manufacturing because the high temperatures involved would degrade activated carbon post-treatment systems, making filter-based oil removal less effective precisely at the process step where it is most critical.

Key Features

7.80 m³/min Heavy Industrial Volume

At 7.80 m³/min (275 cfm), the EP-CM45BF serves IS glass machine installations of 6–8 sections, large food production facilities with simultaneous process air requirements across multiple lines, or printing press installations requiring sustained high-volume air at stable pressure throughout production shifts.

68 dB(A) at 45 kW Industrial Output

Achieving 68 dB(A) at 45 kW output requires the full noise engineering package of the single-screw water-lubricated platform: no belt transmission, no gear train, the smooth orbital compression cycle, and the CMN-patented acoustic enclosure with high-density sound-absorbing material. Conventional piston or twin-screw compressors at 45 kW typically produce 80–90 dB(A).

Water-Cooled and Air-Cooled Variants

The water-cooled model (1930 kg, 3040×1280×1800 mm) connects to a cooling tower or chilled water circuit — standard for large glass container and food factory installations. The air-cooled model (1430 kg, 2200×1350×1530 mm) is self-contained for facilities without cooling water, with fan cooling maintaining discharge temperature below 55°C in ambient conditions up to 40°C.

Isothermal Efficiency at 45 kW Scale

At 45 kW and 8,000 annual operating hours, the 10%+ specific power advantage of isothermal versus adiabatic compression represents approximately 36,000 kWh of annual electricity saving. Over the 25-year service life, this cumulative saving is substantial — and is realised automatically in every operating hour without additional operational adjustment or investment.

Stainless Steel Air Path — Food and Pharma Compatible

All internal surfaces contacting compressed air — air end housing, separation barrel, piping, and discharge connections — are stainless steel. This all-stainless-steel configuration is the required construction standard for pharmaceutical glass container forming air and food-grade process air, eliminating rust, scale, and metallic particle contamination from the air supply.

Schneider Electric Logic Control

The industrial-grade Schneider Electric PLC provides advanced fault monitoring, early warning function outputs, and a human-machine interface displaying all real-time operating parameters. For glass container and food production facilities operating under formal quality management systems, the PLC's fault log and maintenance reminder outputs provide the documentation trail required for quality audits.

Customer Case Studies

Portugal — Pharmaceutical Glass Container Producer

Industry: Pharmaceutical Packaging  |  Application: Oil-free forming air for IS machine producing Type I borosilicate glass vials

"Pharmaceutical glass vial production requires the strictest possible forming air purity — the air contacts the molten glass that will become the primary packaging for injectable drugs. The EP-CM45BF's structural Class 0 forming air eliminated our vial surface inclusion defect rate from 0.8% to effectively zero. Our regulatory validation team completed the compressed air qualification in one day, using the TUV Class 0 certificate as the primary evidence document."

★★★★★

Indonesia — Large-Scale Noodle and Snack Food Factory

Industry: Food Manufacturing  |  Application: HACCP-compliant oil-free air for multi-line noodle forming, drying conveyor control, and packaging pneumatics

"Our factory runs four noodle lines simultaneously with shared compressed air. Previous oil-injected supply caused periodic product contamination flags during hygiene audits. The EP-CM45BF replaced the compressor and all downstream oil-removal equipment with a single water-lubricated unit — one machine, one TUV certificate, zero oil contamination flags in 20 months. The 7.80 m³/min output is sufficient for all four lines at full production speed."

★★★★★

Czech Republic — Large Commercial Printing House

Industry: Industrial Printing  |  Application: Compressed air for 6 offset printing presses and UV coating lines

"Our six offset presses and UV coating lines run simultaneously during production hours. We previously managed three separate compressors — two oil-injected, one oil-free — to handle the combined demand. The EP-CM45BF replaced all three with a single machine. Print quality has been more consistent since the switch — our pressroom manager attributes part of the improvement to the stable, contamination-free air supply from the water-lubricated system."

Frequently Asked Questions

Why is oil-free air essential for glass container manufacturing?
Glass container forming — IS machine blank mould cooling, neck ring air, and finish cooling — uses compressed air that contacts the hot glass surface directly during forming. Oil contamination in forming air creates surface inclusions, delamination, and colour defects in the finished glass. For pharmaceutical glass containers, any oil contamination of the forming air is an immediate regulatory compliance failure. The EP-CM45BF's structural Class 0 oil-free air eliminates contamination from the forming air circuit at the source.
How does 7.80 m³/min output translate to glass container production capacity?
At 7.80 m³/min and 0.8 MPa, the EP-CM45BF can supply a medium IS machine installation — typically 6 to 8 sections — with blank mould cooling, finish cooling, and neck ring air simultaneously. Exact requirements vary by bottle weight, section speed, and gob weight; Ever Power's engineering team can calculate precise requirements based on your specific IS machine configuration.
Can the EP-CM45BF handle the high-volume pulsed demand of a printing press?
Large offset and flexographic printing presses use compressed air for sheet feeding, gripper timing, impression cylinder control, and ink delivery systems — all pulsed demand loads at varying frequencies. The EP-CM45BF's 7.80 m³/min output provides sufficient volume for large multi-colour press installations, and a suitably sized air receiver smooths the pulsed demand to maintain stable pressure at all press air inlets.
What is the weight and footprint of the EP-CM45BF — does it require special foundation work?
The water-cooled model weighs 1930 kg and has a footprint of 3040×1280 mm. The air-cooled model weighs 1430 kg with a footprint of 2200×1350 mm. For most industrial floor constructions, standard reinforced concrete slab loading is adequate for these weights. Anti-vibration mounts are recommended rather than rigid bolting for most installations to prevent structure-borne noise transmission.
Is the EP-CM45BF suitable for 24-hour continuous production environments?
Yes. The EP-CM45BF is designed for 7×24 continuous operation with a 25-year air end design life. The water lubrication system maintains the compression chamber at ambient +15°C throughout continuous operation, preventing the thermal fatigue that limits some compressor designs under extended duty. Scheduled maintenance consists of periodic filter replacement and annual bearing greasing — intervals that can be planned during production downtime windows.
