7.5kW High Pressure 4 in 1 Fixed Speed Air Compressor

Elily’s 7.5kW high-pressure 4-in-1 fixed-speed air compressor supports adjustable pressure from 10–15 bar with an integrated installation-free structure. Engineered for long-term high-pressure operation, it delivers an economical solution for low-flow, high-pressure compressed air demands.

Specialized Fixed-Speed High-Pressure Configuration

This unit adopts a tailor-made high-pressure airend together with reinforced pressure-resistant pipelines and valves to sustain stable continuous operation at 1.0–1.5 MPa. Different from conventional low-pressure compressors, the optimized high-pressure compression ratio avoids overheating and backpressure troubles. Without complex inverter components, the machine boasts a low failure rate, perfect for scenarios demanding steady high-pressure air supply.

Integrated 4-in-1 Structure Simplifies Installation

Combining airend, high-pressure air tank, dedicated refrigerated dryer and four-stage filtration into one compact unit, all high-pressure airtight testing is finished in the factory. No separate post-processing equipment or on-site high-pressure piping assembly and leak inspection are required. The small footprint enables direct placement within compact workshops and laboratories.

High-Pressure Post-Treatment Avoids Condensation

Fitted with a 1.4 m³/min high-pressure refrigerated dryer equipped with an optimized heat exchanger, it maintains a stable outlet dew point ≤3°C. Gradient four-stage filtration effectively eliminates oil mist and contaminants, preventing water buildup and blockages in high-pressure pipelines to safeguard downstream precision valves and testing devices.

Strict Factory Testing Guarantees Reliability

Each compressor undergoes stringent factory inspections including a 1.5 MPa pressure holding test, airtightness detection and temperature rise monitoring. The whole machine adopts vibration-damping reinforced construction. Proven in long-term field use for electronic air tightness testing and small-scale blow molding, it runs continuously with minimal faults. The mature fixed-speed design also keeps daily maintenance easy and affordable.

Logistics and Delivery

The 7.5kW high-pressure 4-in-1 fixed-speed air compressor is fixed onto a reinforced wooden pallet and wrapped with stretch film for shock resistance. Before shipment, pressure inside the air tank is fully released, and all high-pressure connection ports are sealed for protection.

We arrange dedicated truck delivery to customers’ sites for domestic orders. For overseas exports, we prepare a complete set of documents required for customs clearance of high-pressure industrial equipment. Comprehensive long-distance transportation safeguards prevent tipping and collision damage. We also offer professional guidance for equipment inspection upon arrival.

FAQ

Q: Can this 7.5kW fixed-speed compressor sustain stable pressure at 15 bar?

A: Yes. The airend and pipelines are custom engineered for 1.5 MPa high-pressure working conditions to guarantee stable long-term operation. Please note that the customized high-pressure version comes with slightly reduced airflow capacity, which is a normal technical feature.

Q: What is your MOQ? Do you support OEM customization?

A: The minimum order quantity is 1 unit. OEM services are available, with a production lead time of 15–25 working days.

Q: Are you a manufacturer or trading company?

A: We are a professional manufacturer located in Dongguan, Guangdong. Our production plant covers 20,000 m², enabling us to offer factory-direct prices and full technical support.

Q: How long is the sea freight transit time to Europe and the Americas?

A: Our standard production lead time is 15–20 working days. For shipping, it takes around 7–12 days to Southeast Asia, and 25–35 days to Europe and the Americas. Door-to-door delivery service can be arranged upon request.

Q: What after-sales support can overseas customers obtain?

A: We provide 24/7 online technical consultation and remote video troubleshooting within two working days. Critical spare parts can be delivered via international express. On-site engineer support is also negotiable when required.
