LISHAN 4-in-1 Integrated Permanent Magnet VFD Screw Air Compressor

All-in-one integrated design, plug-and-play
 

Integrated with screw airend, refrigerated dryer, precision filters and air storage tank. All pipelines pre-installed in factory. Customers only need to connect power and air outlet to start production, no extra pipe assembly work required.

Mobile wheel design for flexible movement
 

Equipped with heavy-duty universal casters, easy to shift between laser cutting stations, ideal for small metalworking & sign factories without fixed machine room.

IE5 permanent magnet VSD system, 30~40% power saving
 

High-efficiency PM synchronous motor with variable frequency drive automatically adjusts air output based on real consumption, no idle energy waste. Constant air pressure fluctuation within ±0.1 bar, perfectly fit fiber laser cutting.

Space-saving compact structure
 

40% smaller footprint than separate split units, saves workshop space and factory rental cost for small workshops.

Clean & stable compressed air output
 

Built-in dryer and multi-stage filters fully remove water, oil and dust, prevent fogging laser lens and rough cutting edges.

Unified intelligent touch control panel
 

One PLC screen monitors all running data of compressor, dryer and tank at the same time, easy operation for new operators without separate debugging.

One-stop purchasing solution, lower procurement cost
 

Clients get complete air supply system by ordering one machine only, no need to source compressors, tanks and dryers from different suppliers.

Low overall operation noise

Integrated sound insulation cabinet and shock-absorbing pads reduce superimposed noise caused by multiple split equipment.

Simplified after-sales service

All supporting components under one unit, maintenance and fault troubleshooting only rely on one supplier, no multiple after-sale contacts.

This integrated compressor runs with low noise, the sound level is only 62–68 dB(A) during operation, much quieter than conventional fixed-speed split air compressors (75~85dB).

Noise reduction design:

Full closed sound insulation cabinet with high-density sound-absorbing cotton inside to block operating noise of the airend.

Thick shock-absorbing pads under the motor and screw rotor, cutting down vibration noise.

All pipelines are fixed with shock-absorbing clamps to avoid resonance noise.

The PM VFD motor mostly runs at low speed without frequent heavy-duty startup impact noise.

Unlike split equipment (compressor, dryer, tank working separately with superimposed loud noise), this all-in-one unit concentrates noise control. Workers can talk normally beside the machine without interference, meeting industrial environmental noise standards.

Note:

Loud abnormal noise only occurs if the machine is unleveled or internal fixing screws get loose. Regular simple maintenance can keep low noise performance long-term.
