55kW Standalone Low Pressure Fixed Speed Air Compressor

Elily 55kW Standalone Low-Pressure Fixed-Speed Rotary Screw Air Compressor is professionally optimized for 0.3–0.6 MPa (3–6 bar) low-pressure and high-flow working scenarios. With a mature industrial-frequency direct-drive structure, it delivers sturdy durability and outstanding cost performance, serving as the ideal main unit for low-pressure air supply and energy-saving upgrades in small and medium-sized factories.

Dedicated Low-Pressure Design, Source Energy Saving

The airend rotor profile, clearance, intake valve and piping system are fully customized for low-pressure operation. Direct 3–6 bar air output completely eliminates throttling waste caused by traditional high-pressure compressors with pressure reducing valves, achieving 20%–30% overall energy savings. The working pressure can be customized within 0.3–0.6 MPa to precisely match different production processes.

Stable 55kW Direct-Drive Operation

Powered by a 380V/50Hz industrial asynchronous motor with 100% efficient direct-drive transmission, this fixed-speed model removes fragile inverter components. Its simplified circuit structure features excellent dust, high-temperature and low-temperature resistance, supporting reliable 24-hour full-load continuous operation with ultra-low failure rates. Adopting a large low-speed rotor design, the unit runs smoothly with low vibration, and noise is controlled below 72dB, requiring no additional soundproof room.

High Continuous Airflow for Industrial Use

It provides a stable airflow of 11–13 m³/min at 0.4–0.5 MPa, perfectly meeting continuous high-flow demands for textile air-jet looms, pneumatic material conveying, industrial dust removal, purging and ceramic molding. Equipped with an enlarged radiator and forced air cooling system, it keeps exhaust temperature ≤90℃ under 35℃ ambient full-load conditions, effectively preventing high-temperature shutdowns.

Compact Structure & Flexible Configuration

As a standalone tank-free model, it allows free combination with external air tanks, refrigerated dryers and filters for flexible system matching. The compact structure saves workshop space with simple installation and wiring. Built-in LED digital display shows real-time pressure, temperature and running data. With highly universal spare parts, daily maintenance only requires regular oil and filter replacement, greatly reducing long-term operating costs.
