China 20bar pressure Screw Air Compressor for laser cutting machine Supplier, Suppliers
Product Description
1. Product Overview
Our EU & E series screw air compressors are high-efficiency, stable industrial air supply equipment, covering power range from 7.5kW to 37kW. With mature screw compression technology, they stably provide compressed air under 1.3MPa and 1.6MPa working pressure; the E-37GA model supports extra high pressure options (1.6MPa/2.0MPa). Widely applied in machinery manufacturing, packaging, plastic, food, textile, construction and other industries as core air source equipment.
2. Core Performance Advantages
(1) Stable & High Air Output
Two sets of standard working pressure configurations for flexible matching:
- 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
Equipped with high-efficiency three-phase asynchronous motor, power marked as KW/HP (7.5HP–50HP range):
- 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
Integrated all-in-one design (host + motor + cooling system + control cabinet):
- 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.
