Product Specifications

Product Features

The 37KW 7.1m³/min Two-Stage Energy-Saving Air Compressor combines a two-stage compression system with variable speed control and integrated components for industrial compressed air applications.

1. Two-Stage Compression

Two air ends and an inter-stage cooler compress air in two steps, helping reduce compression heat and improve operating efficiency.

2. 37 kW Motor and Air Delivery

Provides 7.1m³/min rated airflow at 0.8 MPa for medium-to-large industrial compressed air requirements.

3. Permanent Magnet VSD

Adjusts motor speed according to actual air demand, helping reduce unnecessary energy consumption during variable-load operation.

4. Integrated Cooling and Filtration

The inter-cooler and oil separation system support temperature control and compressed air treatment within the unit.

5. Intelligent PLC Control

The control panel provides an LED display, fault alarms, a remote monitoring interface and scheduled maintenance reminders.

6. Enclosed Noise-Reduction Canopy

The enclosed structure incorporates sound-absorbing material to reduce operating noise in industrial working environments.

Product Advantages

Compared with conventional single-stage compression units, this two-stage air compressor offers several advantages in industrial operation:

• Energy-efficient compression: The two-stage design and permanent magnet VSD help optimize energy consumption under suitable operating conditions.
• Lower Compression Temperature: Inter-stage cooling helps reduce the temperature of compressed air between compression stages.
• Stable Air Supply: Variable speed control helps match compressor output with changing air demand.
• Compact Installation: The integrated skid-mounted structure helps simplify equipment arrangement and on-site installation.
• Air-End Performance: An optimized rotor profile and precision manufacturing support efficient compression and reliable operation.
• Convenient Maintenance: The integrated design and intelligent control system facilitate routine inspection and equipment management.

Frequently Asked Questions

Q1. How do I choose the right motor power and air displacement for my factory?

Calculate the total air consumption of all pneumatic equipment operating simultaneously, then allow an appropriate capacity margin. Consider working pressure, operating hours, load variations and future expansion. Huitengda can help evaluate your compressed air requirements and select a suitable model.

Q2. Should I choose a fixed-speed or VSD air compressor?

A VSD air compressor is generally suitable for applications with fluctuating air demand because its motor speed can adjust to the required output. A fixed-speed model may be suitable for applications with relatively stable and continuous air consumption. The choice should be based on the actual load profile and operating conditions.

Q3. Does the air compressor need an air dryer and filters?

Air treatment equipment is selected according to the required compressed air quality. A refrigerated air dryer and suitable filters are commonly used to remove moisture, oil aerosols and solid particles. Applications requiring higher air purity may need additional treatment equipment.

Q4. What should I check if the compressor alarms due to high exhaust temperature?

Check the cooling fan, cooler surfaces, lubricant level and ventilation around the compressor. Dust accumulation, insufficient cooling airflow or high ambient temperature may contribute to elevated exhaust temperatures. Follow the equipment manual and check the alarm information before restarting the unit.

Q5. Why is the compressor consuming more lubricant than normal?

Possible causes include an incorrect lubricant level, unsuitable lubricant, a damaged oil separator element or leakage within the system. Inspect the lubricant level and separator condition, and use the lubricant grade specified for the compressor model.

Q6. Why does the air pressure drop during production?

Pressure drops may result from undersized pipelines, insufficient air receiver capacity, pipeline leakage or air consumption exceeding the compressor's available output. Check the entire compressed air system, including piping, storage capacity and actual demand.
