7.5kW High Pressure Tank Mounted Fixed Speed Air Compressor

The Elily 7.5kW High-Pressure Tank-Mounted Fixed-Speed Air Compressor supports customizable working pressure from 10 bar to 15 bar. The main airend, pipelines and valve components are all reinforced with professional high-pressure structure, making it a highly reliable replacement for traditional piston compressors. It is widely applicable for bottle blowing, glass cutting, industrial high-pressure testing and other high-pressure production scenarios.

Adopting a pure fixed-speed operation design, the unit removes vulnerable VFD components, effectively cutting 20%–30% of initial procurement costs. With universal standard accessories and extremely low maintenance requirements, it only needs routine oil filter replacement every 2,000 working hours, perfectly adapting to 24-hour uninterrupted high-pressure continuous operation.

Featuring an integrated base structure combining the compressor host and high-pressure air receiver tank, the unit completes strict factory pressure holding and air tightness tests before delivery. It supports plug-and-play operation after simple power and pipeline connection. The compact layout saves more than 0.5 m² of workshop space, reduces external pipeline connections, and greatly lowers the risk of air leakage during high-pressure operation.

Equipped with a 25% enlarged radiator and high-power cooling fan, the machine maintains a discharge temperature below 85°C under full-load operation at an ambient temperature of 35°C, completely avoiding high-temperature shutdowns and pressure drop issues. The running noise is controlled steadily at 63–68 dB, requiring no additional soundproof room and allowing direct indoor workshop placement.

In addition, the unit is fitted with an LED digital intelligent controller, enabling one-touch adjustment and setting of start-stop pressure parameters. It delivers simple, efficient and user-friendly operation for various industrial production environments.

Genuine Customer Feedback

FAQ

Q: Can this 7.5kW High-Pressure Tank-Mounted Fixed-Speed Air Compressor achieve 1.6 MPa working pressure?

A: Yes. Units ranging from 7.5kW to 22kW can be customized for 1.6 MPa high-pressure service via upgraded high-pressure airend and pressure-resistant pipelines. Please note that free air delivery (FAD) will drop by 15–20% after modification. Our sales team can work out the exact airflow data to match your air consumption requirements.

Q: Is the integrated high-pressure air receiver safe to operate?

A: Absolutely safe and fully compliant with standards. The air receiver is an officially certified pressure vessel with a design pressure 1.5 times the rated working pressure. Every tank passes factory pressure holding and air tightness testing and is equipped with dual safety valves for automatic overpressure relief. Official inspection certificates are supplied together with the unit for worry-free operation.

Q: What is the actual operating noise of this high-pressure fixed-speed unit?

A: At a 1-meter distance under full-load running conditions, the noise level measures 63–68 dB(A), similar to daily conversation. It is over 30 dB quieter than high-pressure piston compressors. No dedicated soundproof room is needed, and the machine can be installed directly alongside production lines.

Q: How to select between high-pressure fixed-speed and variable-frequency (VFD) models?

A: Select the fixed-speed model if you maintain steady 24-hour air demand with budget constraints. It features lower purchase and maintenance costs and a robust mechanical structure. Opt for the VFD model if your air demand fluctuates widely. It adjusts rotational speed according to real-time consumption to achieve long-term energy savings.

Q: Do high-pressure units require 380V power supply?

A: Yes. High-pressure compressors of 7.5kW and above work under heavy load and require 380V three-phase industrial power supply. Running this high-pressure unit without three-phase power is not recommended. A conventional low-pressure compressor will be a more suitable alternative.

Q: What is the lead time for standard and customized high-pressure versions?

A: In-stock standard 1.3 MPa units can be dispatched within 3 working days. Customized 1.6 MPa high-pressure versions require a production lead time of 7–10 working days once your order is confirmed.

Q: Can I receive support for installation and commissioning?

A: Yes. We provide one-on-one remote video guidance for installation and commissioning after shipment. Each unit is delivered with a detailed illustrated operation manual and tutorial videos. For most working conditions, on-site professional service is unnecessary, and the compressor can be commissioned and put into service through simple steps.
