37kW Standalone Low Pressure Fixed Speed Air Compressor

Core Selling Points:

Elily’s 37kW Standalone Low-Pressure Fixed-Speed Rotary Screw Air Compressor is a premium direct-drive screw unit engineered exclusively for low-pressure working conditions. It eliminates massive energy waste from the conventional solution of high-pressure compressors fitted with pressure reducing valves. Delivering steady, reliable compressed air during long-term full-load operation, it brings tangible benefits with minimal maintenance expenditure.

Specialized Low-Pressure Design

1. Core Parameters: Powered by a 37kW fixed-speed motor, it delivers roughly 6.0 m³/min free air delivery at 0.8 MPa.

2. Energy-Saving Low-Pressure Architecture: Optimized for 0.3–0.5 MPa working scenarios, it cuts 20%–50% energy loss compared to high-pressure compressors used with pressure reduction valves.

3. High-Efficiency Airend: Features large low-speed rotors with optimized profiles to reduce internal leakage, guaranteeing generous airflow and stable air pressure.

Reliability & Long Service Life

1. Proven Simple Structure: Free from sophisticated components such as inverters, it supports direct fixed-speed startup with far fewer potential fault points.

2. Robust Construction: Shaft-driven air intake lowers noise and extends service life. Widely interchangeable spare parts keep maintenance expenses in check.

3. Adaptable to Harsh Conditions: Optional upgraded cooling and sealing packages are available for high-temperature or dusty workshops, supporting stable 24/7 continuous operation.

Outstanding Cost Performance

1. Lower Upfront Expense: Simplified construction reduces procurement costs by 20%–30% versus equivalent variable-frequency models, ideal for budget-conscious buyers.

2. Minimal Maintenance Outlay: Built on mature technology with a long service life cycle; only regular routine servicing is needed to keep repair costs low.

FAQ：

Q: Can the working pressure of the 37kW Standalone Low-Pressure Fixed-Speed Air Compressor be customized?

A: Yes. Custom pressure ranging from 3–6 bar is available. We preset the target operating pressure at the factory according to your on-site requirements to avoid post-installation adjustments, perfectly matching low-pressure purging and pneumatic conveying equipment.

Q: Does this standalone compressor come with an integrated air receiver tank?

A: No built-in air tank. You can directly connect it to your existing air tank, filters and refrigerated dryers to establish a complete low-pressure air system. It is highly flexible for workshop renovation and equipment replacement projects.

Q: Is this unit applicable for dust removal, air purging and material conveying?

A: Absolutely. Optimized for industrial 3–6 bar low-pressure working conditions, it delivers steady constant air pressure, ideal for workshop cleaning, environmental dust removal, powder pneumatic conveying and textile production air supply.

Q: Does the unit produce loud noise? Can it be installed inside workshops?

A: The machine adopts optimized vibration and noise reduction design. Without high-frequency noise generated by inverters, its operating noise is 2–3 dB lower than variable-frequency models. It can be placed directly inside production workshops and assembly lines without disrupting daily production.

Q: How to select among 37kW, 55kW and 75kW low-pressure models?

A: Select based on required airflow:

- 37kW: Light-duty low-pressure purging

- 55kW: Centralized air supply or material conveying for medium workshops

- 75kW: Large production lines and high-flow dust removal systems

Q: Does fixed-speed compressor deliver more stable air pressure than variable-frequency type?

A: When equipped with an adequate air receiver tank, pressure fluctuation of the fixed-speed unit can be controlled within ±0.03 MPa, satisfying the demands of most low-pressure industrial applications. Variable-frequency compressors are only recommended for scenarios with ultra-strict pressure stability requirements.
