7.5 kW 1.1 m³/min Permanent Magnet VSD Air Compressor

As a professional air compressor supplier from China, Huitengda offers the FU-7PM 7.5 kW 1.1 m³/min Permanent Magnet VSD Air Compressor for applications with varying compressed-air requirements. The unit combines a permanent magnet synchronous motor with a variable speed drive (VSD), allowing motor speed to adjust in response to changes in air demand.

Compared with fixed-speed operation, this control method can help reduce unnecessary energy consumption during partial-load operation. Actual energy savings depend on the operating profile, system pressure and air consumption. With a rated pressure of 0.8 MPa and a listed air delivery of 1.1 m³/min, the FU-7PM can be evaluated for pneumatic tools, air cylinders and other light industrial applications requiring a suitable compressed-air supply.

Technical Specifications

Product Structure

The Huitengda 7.5 kW 1.1 m³/min Permanent Magnet VSD Air Compressor integrates key components for air compression, filtration, speed control and cooling.

1. Oil-Gas Separator Tank: Separates oil from compressed air during operation.

2. Screw Air End: Compresses air to provide a continuous compressed-air supply.

3. Permanent Magnet Motor: Drives the screw air end.

4. Frequency Converter: Adjusts motor speed according to air demand.

5. Air Filter: Filters incoming air before compression.

6. Oil Filter: Removes contaminants from the compressor oil.

7. Air-Cooled Cooler: Helps remove heat from the compressor system.

8. Cooling Fins: Increase the heat-dissipation surface area to support cooling.

9. Soundproof Cotton: Helps reduce operating noise inside the enclosure.

Product Features

1. Variable-Speed Control

The VSD adjusts motor speed as compressed-air demand changes. This operating method can be useful in applications with fluctuating air consumption, although actual energy performance depends on operating conditions.

2. Permanent Magnet Motor Drive

The permanent magnet synchronous motor drives the screw air end. The motor and VSD work together to regulate compressor operation according to the required air supply.

3. Integrated Filtration and Cooling

The air filter, oil filter, oil-gas separation system and cooling components support the compressor's operating process. Regular inspection and maintenance help keep these components in suitable working condition.

4. Compact Installation Footprint

With listed dimensions of 900 × 650 × 850 mm and a weight of 200 kg, the FU-7PM can be assessed for installations with limited floor space. Additional clearance is required for ventilation, inspection and maintenance.

5. CE Documentation

The FU-7PM is accompanied by corresponding CE documentation. Refer to the displayed certificate image for details.

Applications

The FU-7PM can be evaluated for compressed-air applications such as:

● Pneumatic tools: Air supply for suitable workshop tools and light assembly operations.

● Air cylinders: Pneumatic actuation in equipment and production lines.

●Blow-off cleaning: Removal of dust and loose particles from suitable work areas or components.

● Spray guns: Compressed-air supply when paired with appropriate air filtration and moisture control.

● Light pneumatic conveying and small blow-molding equipment: Subject to the required pressure, air volume and duty cycle.

How to Select the Right Compressor?

Three factors are particularly important when assessing the FU-7PM:

1. Air consumption: Compare the compressor's available output with the combined demand of connected equipment, including periods of simultaneous operation.

2. Working pressure: Confirm that the rated pressure of 0.8 MPa meets the equipment requirement after pressure losses in the distribution system.

3. Air quality: Determine whether the application requires an air dryer, filters or oil and water separation.

Installation Notes

1. Ventilation: Install the compressor in a well-ventilated area with sufficient clearance for cooling and maintenance.

2. Power Supply: Ensure the electrical supply matches the compressor's rated voltage and frequency.

3. Air Piping: Use correctly sized pipes and secure connections to minimize pressure loss and air leakage.

4. Foundation: Place the unit on a stable, level surface capable of supporting its operating weight.

5. Maintenance Access: Leave adequate space for routine inspection, filter replacement and servicing.

FAQ

1. What is the air delivery of the FU-7PM?

The listed air delivery is 1.1 m³/min. Check the manufacturer's test conditions and rated pressure when comparing this model with other compressors.

2. How does a VSD air compressor respond to changing air demand?

The variable speed drive adjusts motor speed as demand changes, allowing the compressor to regulate its operation rather than relying solely on fixed-speed running.

3. Can this model reduce energy consumption?

Variable-speed operation can help reduce energy consumption under suitable variable-load conditions. No fixed saving percentage should be assumed without data from the actual operating conditions and a suitable comparison.

4. Does the FU-7PM require an air dryer?

That depends on the application. Where moisture levels affect the process or equipment, an appropriately sized air dryer and suitable filtration may be required.

5. What information is needed to assess model suitability?

Provide the required air flow, working pressure, operating schedule and air-quality requirements. These details help determine whether the FU-7PM matches the application.
