EP-CMW4.4-1.0 Oil-Free Scroll Air Compressor
The EP-CMW4.4-1.0 pairs two 2.2 kW scroll heads to deliver 430 L/min of oil-free air at 1.0 MPa — combining dual-head operational redundancy with demand-adaptive load sharing for pharmaceutical, clinical, and high-pressure precision applications where supply interruption is not acceptable.
EP-CMW4.4-1.0: Dual Air-End (2 x 2.2 kW) 1.0 MPa Oil-Free Scroll Compressor -- 430 L/min
The EP-CMW4.4-1.0 is a dual air-end (2 x 2.2 kw) configuration in Ever Power's 1.0 MPa range, delivering 430 L/min of certified oil-free air at up to 1.0 MPa from 4.4 kW total drive power. Noise level: 52 +/- 3 dB(A). Weight: 150 kg. Dimensions: 800 x 650 x 1020 mm. Outlet: 1/2 inch stainless steel. All air-ends carry a 2-year warranty. The touch-screen PLC manages demand-based head sequencing, automatic lead rotation, and per-head maintenance reminders. View all options in the full EP-CMW range.
The dual-head architecture enables demand-adaptive load sharing at 1.0 MPa: at lower production demand, one head supplies the full load; when demand rises, the second head is brought online automatically by the PLC without operator input. Automatic lead rotation distributes 1.0 MPa running hours equally across both mechanisms over time.
Engineering Foundation Behind the 1.0 MPa Multi-Head Range
Ever Power's multi-head scroll compressors scale proven individual scroll head engineering -- the same high-stiffness square air-end design, direct-drive permanent magnet motor, and 1 micron inlet filtration -- across multiple mechanisms in a single managed cabinet. The company manufactured the world-first 1.2 MPa oil-free scroll compressor and contributed to national standards JB/T 11882-2014 and JB/T 12565-2015. All air-ends in this model carry unconditional 2-year warranties.
Key Features
430 L/min Dual-Head Output at 1.0 MPa
Two 2.2 kW heads coordinate to deliver 430 L/min at full 1.0 MPa. If one head is under scheduled maintenance, the second continues supplying 215 L/min at 1.0 MPa -- eliminating planned production stops from compressed air maintenance.
Demand-Adaptive Load Sharing at 1.0 MPa
PLC runs only the heads needed to maintain system pressure within the 1.0 MPa band -- one head for low demand, both for peak demand -- matching energy consumption directly to production activity.
Dual Redundancy for Clinical and Pharmaceutical Applications
Many clinical and pharmaceutical environments mandate no single point of failure in compressed air supply. The dual-head EP-CMW4.4-1.0 meets this requirement at 1.0 MPa from a single 800 x 650 x 1020 mm cabinet.
2 x 2.2 kW IP65 Permanent Magnet Motors
Both motors use direct-drive permanent magnet technology with IP65 protection and F-class insulation, providing 1.0 MPa compression torque at over 94% individual motor efficiency.
Individual PLC Maintenance Tracking per Head
Running hours are tracked per head independently, with separate maintenance reminder notifications ensuring neither head exceeds its service interval while the other accumulates disproportionate hours.
1/2 Inch Stainless Outlet and Dual 1 Micron Filters
Dual independent 1 micron inlet filters protect each scroll mechanism at 1.0 MPa compression, and the stainless steel outlet maintains food-grade air quality throughout.
Scroll Compression at 1.0 MPa
Each scroll head in the EP-CMW4.4-1.0 compresses air through the standard CMW orbital scroll cycle optimised for 1.0 MPa: air enters at the scroll periphery, is sealed into crescent-shaped pockets, and travels through the extended compression path needed for 1.0 MPa output before discharging at the central port. All heads discharge into a common stainless manifold at the 1/2 inch outlet. The PLC continuously monitors system pressure and sequences head operation to maintain pressure within the operating band, rotating lead roles to equalise running hours across all heads.

Customer Case Studies -- EP-CMW4.4-1.0
Australia -- Pharmaceutical Blister Pack Facility
Continuous 1.0 MPa Supply Through Head Maintenance
An Australian pharmaceutical manufacturer eliminated six-hour production stops every 2,000 hours by installing the EP-CMW4.4-1.0. One head is serviced while the second maintains 215 L/min at 1.0 MPa for inter-shift and overnight demand. Zero production stops from compressed air maintenance in 18 months.
★★★★★
"Compressed air maintenance stops eliminated for 18 months. One head runs while we service the other." -- Production Manager
United Kingdom -- Precision Metrology Laboratory
Redundant 1.0 MPa Oil-Free Air for Air-Bearing CMMs
A UK metrology laboratory running air-bearing CMM tables required continuous 1.0 MPa supply with zero contamination. The EP-CMW4.4-1.0 provided dual redundancy and pulse-free output, eliminating air-bearing vibration from their previous piston compressor. CMM measurement repeatability improved measurably after installation.
★★★★★
"Dual redundancy, pulse-free output, and CMM repeatability figures improved noticeably." -- Metrology Manager
Canada -- Multi-Chair Oral Surgery Centre
Clinical Governance Compliance for Six Chairs at 1.0 MPa
A Canadian maxillofacial surgery centre met its clinical governance requirement for no single-point air supply failure with the EP-CMW4.4-1.0. The 430 L/min output at 1.0 MPa served all six chairs concurrently, and infection control confirmed the oil-free output was compliant without additional inline filtration.
★★★★
"No single-point failure -- clinical governance requirement met and oil-free compliance confirmed." -- Infection Control Coordinator
Frequently Asked Questions -- EP-CMW4.4-1.0
What output is available with one head running?
With one head active, the EP-CMW4.4-1.0 delivers 215 L/min at 1.0 MPa -- sufficient for low-demand periods and single-head maintenance windows.
Does the PLC start both heads simultaneously?
No. Sequential starting prevents simultaneous motor inrush current. The second head activates only in response to falling system pressure, not simultaneously with the first.
Can both heads sustain continuous 1.0 MPa operation?
Yes. Both heads are rated for continuous operation at full 1.0 MPa. The combined 430 L/min output is available continuously at working pressure when both heads run.
How are individual head maintenance reminders displayed?
The PLC displays separate maintenance reminder notifications for each head based on independently tracked running hours -- clearly indicating which head requires servicing.
Can this unit serve mixed 0.8 MPa and 1.0 MPa equipment?
Yes. Set system pressure at 1.0 MPa and use downstream regulators for 0.8 MPa-rated equipment. The 0.2-1.0 MPa working range accommodates mixed-pressure installations.
