Configurations
The CM250PV is a premium variable speed drive (VSD) rotary screw air compressor built for UK industrial operations that demand continuous, high-volume compressed air without compromise. Running at 250 kW (340 HP), this machine delivers a free air delivery range of 606 to 1,514 cfm across three configurable working pressures — 116 psi, 145 psi, and 181 psi — making it one of the most versatile large-frame rotary screw compressors available to British manufacturers today. Whether you’re running a heavy automotive press shop in the West Midlands, a large-scale food packaging facility in Yorkshire, or a centralised compressed air ring-main for a multi-site engineering group, the CM250PV has the throughput and the intelligence to match your load profile exactly. Its integrated variable speed control adjusts motor speed in real time, eliminating the energy waste of traditional fixed-speed machines and delivering measurable savings on electricity bills — a particularly important factor given current UK industrial energy tariffs.
How the CM250PV Works
At its core, the CM250PV uses a precision-engineered twin-rotor screw element — a male and female helical rotor that intermesh with extremely tight tolerances — to progressively compress incoming ambient air. As the rotors turn, air is drawn in at the inlet, trapped in reducing cavities between the rotor lobes and the stator housing, and forced out at the discharge port at the selected working pressure. Unlike piston compressors, the screw element produces a virtually pulse-free air delivery, which is critical for downstream processes such as CNC machining centres, spray painting booths, and pneumatic conveying systems where pressure fluctuation causes product defects or process instability.
What makes the CM250PV genuinely different is the variable speed drive system. A permanent magnet motor coupled to an inverter-controlled drive continuously adjusts the rotational speed of the screw element to match actual compressed air demand. During periods of partial load — shift start-ups, weekend running, or seasonal lulls — the motor slows down proportionally, consuming dramatically less power than a fixed-speed machine that would otherwise load/unload repeatedly. This translates directly into lower energy costs, reduced heat output in the compressor room, and significantly longer service life for bearings and seals, since the mechanical stress on the machine is greatly reduced at part-load conditions.
Materials & Build Quality
Screw Element
Forged alloy steel rotors with SKF/FAG heavy-duty bearings. Profiles ground to ISO 1 tolerances for minimal internal leakage and maximum volumetric efficiency across the entire pressure range.
Motor & Drive
IE4-class permanent magnet synchronous motor rated for continuous S1 duty. Matched Siemens/ABB variable frequency drive with STO (Safe Torque Off) function, CE-marked and fully compliant with UK PSSR 2000 regulations.
Cooling System
Full-flow thermostatic oil-cooling circuit with oversized aluminium aftercooler. Maintains oil temperature within 3°C of setpoint in ambient conditions up to 46°C — important for UK summer peaks in un-air-conditioned plant rooms.

Why the CM250PV Outperforms Fixed-Speed Alternatives
Up to 35% Energy Saving
VSD technology matches motor output precisely to demand. UK operators regularly report annual electricity savings exceeding £40,000 per unit compared to equivalent fixed-speed machines on similar duty cycles.
Low 78 dB(A) Noise
Acoustic enclosure and vibration-isolated base frame keep operational noise at 78 dB(A), meeting UK Noise at Work Regulations 2005 without requiring additional acoustic enclosures in most plant layouts.
Extended Service Intervals
Variable speed operation means fewer mechanical stress cycles. Combined with full-synthetic lubricant compatibility, this extends oil service intervals to 6,000 hours and main element overhaul intervals well beyond 40,000 hours in UK-standard operating environments.
Smart Monitoring & Control
The integrated 7-inch colour touchscreen controller logs pressure, temperature, current draw, running hours, and fault history. Remote monitoring via Modbus or optional Ethernet/IP integration connects seamlessly with most UK SCADA and BMS systems.
Heat Recovery Ready
Up to 80% of electrical input energy can be recovered as usable heat for space heating or process hot water via the optional heat recovery module. For UK factories targeting ISO 50001 certification, this is a straightforward route to significant Scope 2 emission reductions.
UK Regulatory Compliance
Ships with full UKCA/CE documentation, pressure vessel certification to PED 2014/68/EU, and PSSR 2000 compliance certificate. Our technical team provides the Written Scheme of Examination (WSE) documentation required by UK law for pressure systems above threshold limits.
Where the CM250PV Excels Across UK Industry
Across England, Scotland, and Wales, the CM250PV has established itself as the go-to large-frame rotary screw compressor for operations that cannot afford downtime and where energy efficiency directly impacts profitability. In UK automotive press shops and body-in-white facilities, the machine’s stable 8 to 13 bar pressure delivery keeps spot welders, pneumatic transfer presses, and jig clamps operating without pressure drop events. In food and drink manufacturing — a sector where compressed air quality is regulated under UK Food Safety legislation — the CM250PV’s compatible oil formulation and optional integrated air-end filtration make ISO 8573-1 Class 1 air quality achievable without costly remote filtration skids. Pharmaceutical and medical device manufacturers in the East Midlands and Thames Valley have adopted the CM250PV specifically for cleanroom support air, appreciating the consistent pressure profile that variable speed delivery provides to sensitive filtration trains. Textile and paper mills in Yorkshire and Lancashire benefit from the machine’s ability to maintain constant pressure on pneumatic loom-control and paper-tension systems even as overall demand fluctuates through the production shift. General engineering fabricators using plasma cutting, robotic MIG welding, and air-powered grinding find the CM250PV’s 3,900 kg footprint compact enough for retrofit into existing compressor rooms, while its output easily supplies ring mains serving 40 or more simultaneous air tools.

Case Study · Midlands Automotive Tier 1 Supplier
Replacing a 20-Year-Old Fixed-Speed Fleet in Coventry
Midlands-based Tier 1 automotive stamping supplier Precision Metal Components Ltd. (Coventry) was running four aging 250 kW fixed-speed compressors with a combined annual electricity bill exceeding £310,000. Frequent load/unload cycling had caused three motor rewinds in two years, and their energy manager was under pressure to reduce Scope 2 emissions ahead of a customer audit. Two CM250PV units operating in lead-lag configuration replaced all four legacy machines in a single weekend shutdown installation during a planned maintenance window.
Within the first 12 months of operation, Precision Metal’s energy data showed a 34% reduction in compressed air electricity consumption — equating to approximately £105,000 in annual savings. The plant’s carbon reporting team recorded a 287-tonne reduction in CO2-equivalent emissions for the year, which was presented to their OEM customer during a sustainability review and contributed directly to contract renewal.

“We supply compressed air to 47 CNC machines across two halls. The CM250PV holds pressure within 0.1 bar of setpoint even during peak morning start-up. Previous units would drop by 0.8 bar during shift changeover and we’d get tool chatter on the precision bores. That problem is gone.”
James H., Engineering Director
Precision CNC Subcontractor · Sheffield, South Yorkshire
“Our food safety auditor specifically commented on the cleanliness of our compressed air documentation. Ever Power provided the full WSE pack, UKCA cert, and a test report within 48 hours of our request. The site manager can pull live pressure and temperature data on his phone via the Modbus gateway. Absolutely the right kit for a modern food factory.”
Sandra T., Operations Manager
Ready Meal Production Facility · Leeds, West Yorkshire
“We were sourcing from a German brand previously and the lead time for a replacement element was 14 weeks. Ever Power committed to a 72-hour emergency replacement element dispatch from their UK distribution partner, and they actually delivered in 60 hours. For a 24/7 operation, that supply chain reliability matters as much as the compressor specification itself.”
Robert M., Maintenance Manager
