20bar pressure Screw Air Compressor for laser cutting machine
1. Product Overview
2. Core Performance Advantages
(1) Stable & High Air Output
- 1.3MPa standard pressure: Stable large displacement, meets daily general factory air consumption
- 1.6MPa high pressure: Higher compression ratio, suitable for high-pressure pneumatic tools, precision processing
E-37GA special version reaches max 2.0MPa pressure, catering to special high-pressure process demands.
Complete displacement gradient from 0.7m³/min to 3.9m³/min, perfectly matching small, medium production lines.
(2) Energy-saving Motor & Reliable Power
- Low energy loss, high conversion efficiency, long continuous operation life
- Stable torque, no overload stall under full-load operation
- Low heating value, effectively reducing unit failure rate during long-time running
(3) Ultra-low Noise Design
- EU-8GA/11GA/15GA models: Noise controlled at 68±2dB(A), close to office noise level
- E-18GA/22GA/30GA/37GA models: Noise 70±2dB(A)
Integrated full sound insulation enclosure, internal noise absorption cotton + shock absorption base, can be placed directly inside production workshop without independent noise reduction room, greatly saving factory layout cost.
(4) Compact Solid Structure & Easy Installation
- Small size footprint: EU small models only 900×850×940mm, easy to move and place in narrow workshops
- Robust frame structure: Unit weight ranges 230kg–850kg, thickened metal frame resists vibration deformation
- Standard outlet interface: 3/4", 1", 1-1/4" caliber, quick connection to air pipes, no complicated transformation
(5) Low Maintenance & Long Service Life
- Precision screw rotor with wear-resistant coating, compression efficiency stays stable for 8–10 years
- Standard independent cooling system, strong heat dissipation, prevents high-temperature shutdown
- Simple internal layout, quick access for oil filter, air filter, oil separator replacement; ordinary workshop workers can complete daily maintenance independently
- Complete protective program: over-temperature, over-current, overload, phase loss automatic alarm & shutdown, effectively protect host and motor
