CM18PVF permanentmagnetisk variabel frekvens skruvluftkompressor
Industrial-grade compressed air engineered for UK manufacturing — 18.5 kW output, three pressure configurations, and up to 35% verifiable energy saving over conventional fixed-speed alternatives.
Precision-Engineered Compressed Air for British Industry
Industrial compressed air accounts for roughly 10% of all electricity consumed in UK manufacturing facilities — a cost that plant managers are under increasing pressure to cut as energy tariffs remain elevated. The CM18PVF permanent magnet variable frequency screw air compressor meets that challenge directly, delivering precisely calibrated output that tracks actual site demand in real time rather than cycling between full load and wasteful idle. Rated at 18.5 kW (25 HP), this unit is available in three pressure configurations — 0.8 MPa (116 psi), 1.0 MPa (145 psi), and 1.25 MPa (181 psi) — giving procurement engineers across British manufacturing, food processing, pharmaceutical packaging, and precision fabrication the flexibility to specify exact process requirements without over-building. With a noise output of just 65 dB(A), the CM18PVF can be installed close to production lines without compromising the working environment or triggering obligations under the UK Control of Noise at Work Regulations 2005. From Coventry automotive suppliers to Yorkshire confectionery producers, and from North London pharmaceutical facilities to Scottish offshore support industries, the CM18PVF is redefining what mid-range industrial compressed air should deliver in terms of both performance and cost of ownership.

Why UK Engineers Specify the CM18PVF
Eight measurable advantages built into every unit leaving the factory
Up to 35% Energy Saving
The variable frequency drive continuously matches motor speed to real-time compressed air demand, eliminating the unloaded running that wastes 15–25% of input power in conventional on/off compressors. At current UK industrial electricity tariffs — typically 26–30p/kWh for SME manufacturers — the CM18PVF’s energy performance translates to verifiable annual savings that commonly offset the capital cost differential over a fixed-speed unit within 18 to 24 months of operation.
IE4 Permanent Magnet Motor
NdFeB rare-earth magnets embedded in the rotor eliminate copper rotor losses entirely, achieving IE4 super-premium efficiency levels at both full and reduced load — something standard IE2 or IE3 induction motors simply cannot match. For UK facilities subject to the Energy Savings Opportunity Scheme (ESOS) or pursuing ISO 50001 certification, specifying an IE4-class PM motor compressor provides measurable evidence of continuous improvement in energy management practice.
65 dB(A) — Workplace Compliant
Running at just 65 dB(A), the CM18PVF sits well below the 80 dB(A) first action level defined in the Control of Noise at Work Regulations 2005. This removes the mandatory hearing protection requirement and opens installation options that noisier compressors simply cannot offer — including placement adjacent to open-plan assembly areas, research environments, and customer-facing production spaces where acoustic comfort directly impacts staff wellbeing and visitor impressions.
Wide Delivery Range: 30–109 cfm
The variable delivery envelope — from 30 cfm at 181 psi through to 109 cfm at 116 psi — accommodates the highly variable demand profiles typical of UK batch production, shift-based manufacturing, and seasonal processing industries. A single CM18PVF can effectively consolidate the duties previously covered by two or three smaller fixed-speed compressors, reducing machine count, maintenance complexity, and compressed air room footprint simultaneously.
Direct Drive — Zero Belt Losses
Direct coupling between the PM motor shaft and the screw element eliminates belt-drive transmission losses — typically 2–5% of input power on conventional designs — and removes the single highest-turnover consumable component in a traditional compressor’s planned maintenance schedule. For UK facilities operating on continuous shift patterns, direct drive meaningfully shortens planned maintenance windows, reduces consumable spend, and cuts the risk of unplanned downtime arising from belt wear or mis-tensioning.
Smart Controller & BMS Integration
The integrated intelligent controller logs operating hours, pressure history, temperature trends, fault codes, and service intervals in real time via a clear touchscreen display. Optional remote connectivity allows the CM18PVF to feed live data into building management systems (BMS) or Industry 4.0 monitoring platforms, enabling UK maintenance teams to schedule predictive interventions rather than reacting to breakdowns — a fundamental shift that reduces lifetime maintenance costs and improves production uptime reliability figures.

How the CM18PVF Works: Technology & Materials
The CM18PVF combines two complementary technologies that, working in concert, eliminate the root causes of inefficiency in traditional fixed-speed compressed air systems. At the core sits a permanent magnet synchronous motor (PMSM) constructed around an NdFeB (neodymium-iron-boron) rare-earth rotor. Unlike conventional induction motors, which rely on induced rotor currents to generate torque — losing energy as heat in the process — the PMSM’s rotor magnets create a constant magnetic field with zero copper loss, sustaining IE4 super-premium efficiency ratings across the entire operating speed range, including the reduced-speed conditions that VFD operation regularly produces.
The variable frequency drive (VFD) monitors header pressure continuously and adjusts motor speed in sub-second response cycles. When a shift begins and demand climbs rapidly, the VFD ramps motor speed upward accordingly; during lunch breaks or planned downtime, it reduces speed to the minimum required to maintain set pressure. Because the PM motor maintains high efficiency even at 30–40% of rated speed — where a standard induction motor would suffer a significant efficiency fall-off — the energy savings accumulate across the full production day rather than only during peak demand periods.
The screw compression element uses precision-ground helical rotors machined from high-alloy tool steel, running within a cast iron housing that provides both structural rigidity and natural vibration attenuation. The intermeshing male and female rotors compress air in a continuous, pulsation-free process — a fundamental advantage over reciprocating compressors in applications sensitive to pressure fluctuation, such as medical-grade spraying, precision filling, and instrumentation supply. The direct-drive arrangement couples motor shaft directly to screw element via a flexible disc coupling, dispensing with belt drive components entirely and reducing the maintenance schedule to primarily oil, filter, and separator element changes.

Client Success Stories
Three documented outcomes from current UK installations
A tier-2 supplier manufacturing pressed steel body components replaced three ageing fixed-speed 15 kW compressors with two CM18PVF units in Q3 2023. The consolidated installation reduced compressed air system energy consumption by 31%, generating annual savings of approximately £14,800 at prevailing industrial tariffs. The 65 dB(A) noise level enabled relocation from a dedicated plant room to the production floor perimeter, freeing 18 square metres of floor space and reducing compressed air distribution pipework by 34 metres.
✅ £14,800/yr saving
✅ 3 machines → 2
A confectionery producer in Leeds installed the CM18PVF in the 1.0 MPa (145 psi) configuration to support packaging and heat-sealing lines with highly variable demand profiles. The VFD’s real-time pressure matching eliminated the micro-pressure-drop fluctuations that had been causing inconsistent seal integrity on their previous fixed-speed unit. Production rejects attributable to compressed air quality issues fell by 78% in the first full quarter of operation, delivering direct material savings alongside the energy efficiency gains.
✅ Stable sealing pressure
✅ 27% energy saving
A GMP-certified contract packager in Enfield specified the CM18PVF for blister sealing and vial blowdown duties, selecting the 1.25 MPa (181 psi) configuration paired with dedicated desiccant dryers and sterile-grade filters to meet ISO 8573-1 Class 1 requirements. The low acoustic signature was critical given the facility’s adjacency to quality control laboratories. After 18 months of continuous operation, the unit had logged over 12,400 running hours with zero unplanned downtime events and a first-year energy performance 29% better than the legacy compressor.
✅ 29% energy saving
What Our UK Clients Say
We evaluated five compressor options before choosing the CM18PVF. The PM motor efficiency combined with VFD responsiveness was decisive. Energy savings matched the projections exactly and the machine has been completely trouble-free over 14 months of two-shift production.
Installation was smooth and the commissioning support from the technical team was excellent. We’ve been running the unit 24/5 at our Leeds facility for over a year with no unplanned interventions. The seal reject rate improvement alone justified the purchase.
For a pharmaceutical GMP site, noise and reliability are non-negotiable. The CM18PVF delivers both without compromise. The smart controller integrates cleanly with our Siemens BMS and the data logging satisfies our validation documentation requirements.
