7.5kW High Pressure 4 in 1 Fixed Speed Air Compressor

The Elily 7.5kW High Pressure 4 in 1 Fixed Speed Air Compressor offers customizable pressure settings (10–15 bar) and an integrated, installation-free design. Built for durability in high-pressure applications, it provides a cost-effective solution for low-flow, high-pressure air requirements.

Specialized Fixed-Speed High-Pressure Configuration

his 7.5kW High Pressure 4 in 1 Fixed Speed Air Compressor utilizes a custom-built high-pressure airend and features reinforced, pressure-resistant piping and valves, ensuring stable continuous operation at pressures of 1.0–1.5 MPa. Unlike standard low-pressure models, it features an optimized high-pressure compression ratio that prevents overheating and back-pressure issues. Its simple, non-inverter design results in a lower failure rate, making it ideal for scenarios requiring constant high-pressure air.

Integrated "4-in-1" Design Eliminates Complex Setup

The unit integrates the airend, high-pressure air receiver, specialized refrigerated dryer, and four-stage filtration system into a single package, with high-pressure airtightness testing completed at the factory. Users avoid the need to purchase separate post-treatment equipment or perform on-site high-pressure piping and leak checks. Its compact footprint allows for direct placement in tight spaces, such as small workshops or laboratories.

High-Pressure Specialized Post-Treatment Prevents Condensation

Equipped with a refrigerated dryer rated for 1.4 m³/min at high pressure, the unit features a heat exchanger optimized for the condensation characteristics of high-pressure air, maintaining a stable outlet pressure dew point of ≤3°C. Four-stage progressive filtration precisely removes oil mist and impurities, preventing water accumulation and blockages in the high-pressure lines, thereby protecting downstream precision valves and testing equipment.

Factory High-Pressure Testing Ensures Durability

Every 7.5kW High Pressure 4 in 1 Fixed Speed Air Compressor undergoes rigorous factory testing, including 1.5 MPa overpressure holding tests, airtightness checks, and temperature rise monitoring, alongside a reinforced, vibration-dampened structural design. Long-term field testing in applications such as electronic airtightness testing and small-scale blow molding demonstrates fault-free continuous operation, while the classic fixed-speed design ensures simple, cost-effective maintenance.

FAQ

Can a 7.5kW fixed-speed compressor stably maintain a pressure of 15 bar?
Yes. The main unit and piping are custom-built for 1.5 MPa high-pressure operation, allowing for stable, long-term performance. The customized model has a slightly lower air displacement, which is a normal operational characteristic.

What is the minimum order quantity (MOQ)? Do you offer OEM services?
The MOQ is one unit. We support OEM customization, with a lead time of 15–25 days.

Are you a factory or a trading company?
We are a manufacturer based in Dongguan, Guangdong, with a 20,000 m² production facility; we provide direct factory pricing and technical support.

How long does sea shipping to Europe or the Americas take?
The production cycle is 15–20 days. Sea shipping takes approximately 7–12 days to Southeast Asia and 25–35 days to Europe and the Americas. Door-to-door service is available.

How do overseas customers receive after-sales support?
We provide 24/7 online technical consultation and remote video diagnostics within two working days. Key spare parts are shipped directly via international courier, and on-site engineering support is available if necessary.
