DECHUAN factory manufactures the high-quality ECO RM Screw Air Compressor. Built around an updated main air end, it yields up to 11% higher air output while cutting power bills by 12% to 30% across 7 kW to 22 kW models, with lube oil carryover kept below 3–5 ppm. Get a fast quote!
Industrial facilities looking for a reliable China supplier can implement the DECHUAN ECO RM Screw Air Compressor to stabilize production line air pressure and cut electrical utility bills. Featuring V-Shield leak-free technology, it eliminates fluid leakage at internal piping joints while maintaining header pressure stability within ±0.1 bar under variable manufacturing loads.
Air end efficiency relies on minimizing air slippage between rotor lobes during compression. The asymmetrical 5:6 lobe geometry inside this air compressor reduces internal re-circulation, raising volumetric air output by up to 11% per kilowatt consumed.
| ECO Performance Benchmarks | Performance Value |
|---|---|
| Air End Displacement Gain | Up to +11% Increase |
| Volumetric Yield Boost | Up to +11% Efficiency |
| Total Power Cost Reduction | 12% to 30% Savings |
| Residual Lube Oil Ceiling | Below 3–5 ppm |
When connected to an external heat recovery skid, the ECO RM Screw Air Compressor oil cooling system transfers waste heat into process water loops, producing utility water up to 70°C for plant washing systems.

Precision processes like fiber laser cutting and heavy workpiece clamping require stable air output above standard 7.5 barg line pressure. Pressure drops during cutting can cause oxidation burrs on sheet metal edges, leading to secondary grinding costs.

Multi-stage oil separation keeps oil carryover below 3 ppm, keeping optics clear and downstream air valves clean.
DECHUAN supplies pre-packaged maintenance options for long-term service of the ECO RM Screw Air Compressor.
Factory-matched 2,000-hour and 4,000-hour filter and seal kits shipped with initial equipment orders.
Original replacement filters carry laser-etched serial numbers for online verification.
Supported by PartsCARE component delivery and PackageCARE full maintenance coverage.
The IE5 permanent magnet VSD motor modulates shaft speed between 40% and 100% capacity. When air consumption drops, the ECO RM Screw Air Compressor controller lowers motor RPM, eliminating unload power loss while maintaining line pressure within ±0.1 bar.
Elevated oil carryover usually indicates a clogged air-oil separator element or fluid breakdown caused by excessive running temperatures. Replacing the separator element restores fluid separation below 3–5 ppm.
The top-mounted cooler utilizes a non-welded horizontal design that absorbs expansion stress caused by continuous heating and cooling cycles, preventing weld fatigue cracks and oil leaks over time.
