DECHUAN, as a professional compressed air system supplier based in China, offers high-performance Industrial centrifugal compressor featuring advanced centrifugal technology for large flow rates above 7,000 m³/h and low pressures up to 2 bar(g). The unit has passed rigorous Class 0 oil-free certification. With energy cost accounting for up to 80% of a compressor's total life-cycle cost, this product helps industrial users significantly reduce operating expenses. It is ideal for bulk procurement and long-term strategic cooperation.
DECHUAN leverages strong supply chain integration and deep technical service experience to deliver the Industrial centrifugal compressor. As the "power heart" of modern industry, compressed air system efficiency and stability directly determine production quality and operating costs. It features high-efficiency centrifugal technology and oil-free clean compression, strictly following international standards to meet diverse needs from single-unit purchases to large-scale project supply.
The product leads in energy efficiency, air quality, reliability, and flexibility.
Energy costs typically account for 80% of a compressor's total life-cycle cost, making energy efficiency DECHUAN's top design goal. Every product uses a self-developed backward-curved impeller design, achieving high efficiency across power and pressure levels. Together with adjustable inlet guide vanes, it saves up to 9% additional energy compared to conventional inlet valve solutions. The efficient after-cooler features compact design, extremely low approach temperature and minimal pressure drop, further improving overall system energy efficiency.
For precision manufacturing, medical, food & beverage, and other industries demanding high air quality, any oil contamination can cause irreversible production losses. DECHUAN's Industrial centrifugal compressor has obtained Class 0 oil‑free certification, adopting a unique double‑seal structure (oil seal and gas seal) ensuring that lubricating oil never enters the compression chamber, eliminating oil contamination at the source and providing 100% oil‑free compressed air.
By optimizing the gearbox and main drive shaft system together with high‑quality bearings and seals, the product adapts to continuous, high‑intensity industrial operation. Its compact structure and few wear parts drastically reduce failure probability and maintenance frequency, ensuring stable production line uptime.
The Industrial centrifugal compressor is equipped with a servo‑motor driven adjustable inlet guide vane actuator, which reliably controls flow across the full regulation range economically, easily responding to dynamic process air demands. Multiple motor options (air‑cooled/water‑cooled), different power levels, and various voltage grades are available for precise matching to different operating conditions.
DECHUAN has established broad cooperation in steel, chemical, automotive, medical, telecom, electronics, hardware, machinery manufacturing, new energy, food & beverage, furniture, packaging, and dozens of other industries. This product is ideal for:

The Industrial centrifugal compressor is DECHUAN's energy‑efficient solution for large‑flow, oil‑free clean compression in modern industry. From ultimate energy efficiency, Class 0 air purity, high reliability, to flexible adaptability, every technical feature aims to reduce total cost of ownership and boost production efficiency. Backed by DECHUAN's full‑chain service capability for compressed air systems, this product has become the preferred power equipment for customers in steel, chemical, automotive, new energy, and many other industries, and is an ideal choice for bulk procurement and long‑term strategic cooperation.
A: This product is optimized for large flow rates of 7,000 m³/h and above and low pressure up to 2 bar(g). Multi‑stage configurations can achieve higher pressures. Final selection depends on actual operating conditions. It is recommended to provide accurate flow, pressure, running hours, and other parameters so that technical staff can recommend the optimal configuration.
A: In large‑flow, continuous operation scenarios, the product offers higher overall efficiency than screw compressors. Key advantages include: ① oil‑free compression (Class 0 certified) eliminating contamination at source; ② compact footprint, fewer wear parts, lower maintenance cost; ③ superior energy efficiency in flow ranges above 7,000 m³/h. For small or fluctuating loads, screw compressors may be more economical, so a comprehensive evaluation is recommended.
A: Class 0 is the highest international oil‑free certification, meaning no detectable oil contaminants in the compressed air. For electronics, pharmaceutical, food & beverage, precision manufacturing, and other high‑requirement industries, oil contamination can cause product rejection, equipment damage, or even safety incidents. DECHUAN's Industrial centrifugal compressor uses a double‑seal design to ensure lubricating oil never enters the compression chamber, guaranteeing air purity and helping customers avoid quality and compliance risks.
A: According to actual test data, using adjustable inlet guide vanes instead of traditional inlet valve solutions saves up to 9% energy under partial load conditions. The servo‑motor driven actuator precisely controls intake airflow, maintaining high partial‑load efficiency across the entire flow regulation range, especially valuable for production scenarios with fluctuating air demands.
A: DECHUAN provides full‑dimension customization from equipment parameters to supporting services: ① flow, pressure, and power can be tailored to operating conditions; ② motor type (air‑cooled/water‑cooled), starting method, voltage grade are flexible; ③ multiple sales channels and competitive pricing available according to brand requirements; ④ total technical solutions including design, installation, commissioning, energy‑saving retrofits, and operation & maintenance. For special requirements, please contact the DECHUAN technical team directly.
A: DECHUAN optimizes supply chain management processes to shorten delivery lead times and ensure on‑time shipment. For after‑sales support, the company offers a 24/7 fast‑response maintenance service system, covering equipment repair, spare parts, technical consulting, energy‑saving retrofits, and full life‑cycle services. With a broad service network and professional technical team, DECHUAN ensures that customers' compressed air systems remain highly efficient and stable.
