Against the backdrop of dual-carbon goals and the comprehensive upgrading of smart manufacturing, China’s industrial air supply system is undergoing a new round of iterative transformation. Industries including food, pharmaceutical, textile, chemical, and light manufacturing increasingly require 0.4–0.55 MPa low-pressure, clean compressed air, making low-pressure air supply a large-scale and normalized production scenario. However, outdated low-pressure air compressors generally suffer from high energy consumption, high failure rates, short service life, and poor adaptability to complex working conditions, failing to meet the demands of modern factories for continuous, high-precision, and low-energy-consumption production. In the wave of industrial upgrading, energy conservation and long-term operational stability have become two core criteria for low-pressure air supply equipment selection, raising a key question for manufacturing enterprises: what type of air compressor can perfectly balance these two advantages and adapt to the new-era low-pressure industrial production scenarios?
With the transformation and upgrading of domestic industrial manufacturing, the air compressor industry is accelerating toward high efficiency, energy conservation, intelligence, and oil-free operation. Customized air supply equipment tailored for precise working conditions is gradually replacing traditional general models, and oil-free low-pressure air compressors have become a mainstream choice for industrial equipment renewal. Supported by national policies such as the Industrial Energy Efficiency Improvement Action Plan and theMotor Energy Efficiency Improvement Plan, backward low-efficiency air compression equipment is being phased out, driving the industrial air supply system to upgrade toward higher efficiency, oil-free performance, intelligent operation, and long service life. Traditional low-pressure air compressors commonly have inherent defects including energy loss through coupling transmission, poor heat dissipation, shutdown failures in high-temperature environments, frequent maintenance, and impurity and condensate contamination in compressed air. These problems lead to higher power costs, intermittent production shutdowns, and increased operation and maintenance losses, making them incapable of long-term stable operation under harsh working conditions.
To meet the upgrading demands of the industry, professional low-pressure oil-free screw air compressors with high energy efficiency, superior stability, and extended service life have emerged as the optimal market choice. Targeting the core pain points of industrial low-pressure air supply, the DECHUAN Atlas GL 37-75 Series Low-Pressure Oil-Free Screw Air Compressors deliver a well-balanced combination of energy conservation and long-term stability through advanced hardware configurations and intelligent control systems. Providing a one-stop high-efficiency solution for industrial low-pressure air supply scenarios, the series has become a benchmark model for low-pressure air compressor upgrades.
Energy-saving design runs through the entire unit to help enterprises reduce operational costs significantly. The series is equipped withIE4 ultra-high-efficiency motors that meet top-tier industry energy efficiency standards. Adopting a high-efficiency gear drive system without coupling power loss, the compressor eliminates invalid energy waste from the power source. Featuring a dedicated low-pressure compression structure tailored for 4–5.5 bar working conditions, it avoids extra energy consumption caused by high-pressure pressure reduction. The unit maintains high-efficiency output under stable air consumption conditions, effectively reducing long-term power consumption and fully complying with national industrial energy efficiency upgrade requirements. In addition, the whole series operates with a low noise level of 68–69 dB(A), creating a low-noise and environmentally friendly production environment.
Built with durable core structures, the unit guarantees long-term stable operation in diverse harsh environments. It adopts a maintenance-free fully enclosed drive system that effectively blocks dust and debris from entering the internal structure and prevents environmental abrasion. The series offers standard and high-temperature versions to accommodate complex temperature conditions: the standard model supports a maximum ambient temperature of 46°C, while the high-temperature model withstands up to 55°C. It enables 24-hour uninterrupted operation in dusty, high-temperature, and continuous-production scenarios. Equipped with IP55 protection class, F-class insulation, B-class temperature rise, and grease-lubricated maintenance-free bearings at the non-drive end, the motor effectively reduces failure rates and extends the overall service life of the compressor.
To protect core components and guarantee air quality, the compressor is fitted with a heavy-duty high-efficiency air intake filter that removes 99.9% of coarse particulate dust. The sturdy spin-on oil filter with a bypass valve efficiently filters oil impurities and protects key compression parts. The independently oversized oil cooler and aftercooler lower the rotor outlet temperature steadily and maintain optimal lubricant performance. The built-in mechanical steam-water separator removes nearly 100% of condensed water, delivering pure oil-free compressed air free of moisture and impurities for stringent production scenarios. Furthermore, the heat exchanger adopts a stress-relief design to eliminate thermal shock damage, greatly improving operational stability and equipment durability.
Intelligent technology simplifies daily maintenance and ensures long-term high-efficiency operation. The unit is equipped with the advanced Elektronikon® touchscreen controller, supporting remote control, alarm output, customized maintenance plans, and network diagnosis. The built-in Smartlink remote diagnosis system monitors real-time operating status, optimizes parameters, and maximizes the overall efficiency and energy-saving performance of the air compressor system. It allows joint control of 2, 4, or 6 compressor units to meet large-scale factory collaborative air supply demands. With OPCUA integration capability, the compressor can be seamlessly connected to enterprise production management systems, realizing digital and intelligent operation and maintenance while lowering manual management costs and ensuring long-term stable and efficient operation.
The Atlas GL 37-75 Series covers mainstream power ratings from 37 kW to 75 kW, with a free air delivery ranging from 8.33 m³/min to 17.4 m³/min and a stable working pressure of 4–5.5 bar, fully catering to low-pressure air supply needs of small, medium, and large industrial facilities. Featuring a compact and rational layout, the standard-size body fits most factory installation environments. All performance parameters are tested and certified in strict accordance with ISO 1217 and ISO 2151 international standards, ensuring authentic and reliable data for industrial low-pressure air supply upgrading.
As the industry evolves, traditional low-efficiency, short-lifespan, and high-maintenance air compressors will be gradually phased out. Energy conservation, operational stability, intelligent control, and long service life have become the core development directions of low-pressure air supply equipment. With top-tier energy-saving configurations, excellent harsh condition adaptability, comprehensive intelligent operation systems, and extended service life, the Atlas GL 37-75 Series Low-Pressure Oil-Free Screw Air Compressors effectively solve key pain points of industrial low-pressure air supply. It empowers manufacturing enterprises with upgraded air supply systems, lower energy costs, and more stable production, setting a new quality benchmark for the low-pressure air compressor industry.
