45KW 9.7m³/min Two-Stage Energy-Saving Air Compressor

Huitengda, China Manufacturer & Supplier of 45KW 9.7m³/min Two-Stage Energy-Saving Air Compressor. 9.7m³/min heavy-duty airflow, 18% energy saving, built for 24/7 industrial operation with a low-exhaust-temperature cooling system.

Product Specifications

Product Features

The 45KW 9.7m³/min Two-Stage Energy-Saving Air Compressor is designed for demanding industrial environments, combining high-capacity air delivery, two-stage compression and intelligent control.

1. Two-Stage Compression Design

Dual high-efficiency air ends and an inter-stage cooler divide the compression process into two stages, helping reduce the compression ratio per stage, control heat generation and improve operating efficiency.

2. 45 kW Motor and 9.7 m³/min Air Delivery

Provides a rated airflow of 9.7m³/min at 0.8 MPa, supporting large factories and production facilities operating multiple pneumatic tools and equipment simultaneously.

3. Permanent Magnet VSD

The permanent magnet variable speed drive adjusts motor speed according to actual air consumption, helping reduce unnecessary energy consumption during low-demand periods.

4. Enlarged Cooling System

The enlarged oil cooler and intercooler improve heat dissipation and help maintain stable operating temperatures in demanding industrial environments.

5. Heavy-Duty Air End

An optimized rotor profile and precision bearings support efficient compression and reliable operation under continuous industrial workloads.

6. Intelligent PLC Control Panel

The intelligent control system features an LED display, automatic fault alarms, a remote monitoring interface and maintenance reminders for convenient equipment management.

Product Advantages

Compared with conventional single-stage 45 kW air compressors, this two-stage model offers several advantages for industrial compressed air systems:

• Improved Energy Efficiency: Two-stage compression combined with permanent magnet VSD helps reduce energy consumption under suitable operating conditions.
• Lower Operating Temperature: The enlarged intercooler and oil cooler help reduce heat accumulation and maintain stable compressor operation.
• Reduced Maintenance Requirements: Effective temperature control helps reduce thermal stress on lubricant and internal components.
• Stable Pressure Output: Variable speed control helps match air delivery with changing production demand.
• Low-Noise Operation: The sound-absorbing canopy helps reduce operating noise in industrial workshops.
• Convenient Installation: The skid-mounted structure simplifies equipment positioning and on-site installation.

Frequently Asked Questions

Q1. How do I know if 45KW / 9.7m³/min is enough for my factory?

Calculate the total air consumption of all pneumatic equipment operating simultaneously and allow an appropriate capacity margin. Consider the required working pressure, operating hours, peak demand and potential production expansion. If your actual demand approaches the available output, additional capacity may be necessary. Huitengda can help assess your requirements and recommend a suitable model.

Q2. When should I choose a 45KW air compressor instead of a 37KW model?

A 45KW model may be more suitable when your factory operates more pneumatic equipment simultaneously, runs multiple shifts or expects production capacity to increase. Compare the actual air consumption and required working pressure of both models before making a selection.

Q3. What should I check if the compressor alarms due to high exhaust temperature?

Check the cooler fins for dust accumulation, the cooling fan, lubricant level and workshop ventilation. Insufficient cooling airflow, blocked cooler surfaces or high ambient temperatures may cause excessive exhaust temperatures. Follow the equipment manual and investigate the alarm before restarting the compressor.

Q4. Why is oil consumption higher than normal?

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

Q5. Why does working pressure drop when production demand increases?

Pressure drops may be caused by undersized main pipelines, insufficient air receiver capacity, leakage in long pipelines or air consumption exceeding the compressor's available output. Inspect the piping network, air storage capacity and actual demand to identify the bottleneck.
