55kW Standalone Low Pressure Fixed Speed Air Compressor

The Elily 55kW Standalone Low Pressure Fixed Speed Air Compressor is optimized for low-pressure, high-flow air usage scenarios of 3-6 kg (0.3-0.6MPa). It adopts industrial frequency direct drive, has a classic structure, and is robust and durable. It is a cost-effective main model for low-pressure air supply and energy-saving renovation in small and medium-sized factories.

Dedicated Low-Pressure Design, Energy Saving at the Source

This 55kW Standalone Low Pressure Fixed Speed Air Compressor is specifically tuned for low-pressure conditions. The main unit profile, rotor clearance, intake valve, and piping system are all matched to a pressure range of 0.3-0.6MPa, directly outputting low-pressure compressed air. This avoids the throttling losses of traditional "high-pressure units + pressure reducing valves," resulting in comprehensive energy savings of 20%-30%. Exhaust pressure can be customized from 3-6 kg to precisely meet different process requirements.

55KW Direct-Drive for Stable Reliability

Equipped with a 55KW industrial-grade asynchronous motor (380V/50Hz three-phase power supply), it features flexible direct-drive transmission with 100% efficiency. Fixed-speed operation eliminates the need for complex electronic components such as frequency converters, resulting in a simple circuit. It is dust-resistant, withstands high and low temperatures, and can operate continuously at full load for 24 hours with an extremely low failure rate. The main unit adopts a large rotor and low-speed design, ensuring smooth operation, low vibration, and noise levels below 72dB, eliminating the need for a separate soundproof room.

Abundant Air Volume, Suitable for Continuous Air Use

Within the 0.4-0.5MPa pressure range, the exhaust volume can reach 11-13 m³/min, meeting the high-flow-rate continuous air requirements of textile air-jet looms, material pneumatic conveying, dust removal and purging, ceramic molding, and other applications. The forced air-cooling system is equipped with a large radiator, ensuring that the exhaust temperature under full load is ≤90℃ at an ambient temperature of 35℃, preventing high-temperature shutdown.

Simple Structure, Flexible Networking

Without a built-in air tank, users can freely combine air tanks, refrigerated dryers, filters, and other post-processing equipment for flexible network configuration. The overall structure is compact, occupying little space, and installation and wiring are simple. A standard LED digital display instrument shows pressure, temperature, and running time in real time. Parts are universal for industrial frequency models; routine maintenance only requires changing lubricating oil and filter elements, resulting in low operating costs.
