About Us

8s production standards， ISO9001:2015

Product is the Statement of Who We are

Safe

Since 2017, we have proudly offered a ten-year warranty policy on our compressors in China. We deeply understand that even a single production halt due to compressor failure could lead to significant losses. That’s why our engineering and production process are guided by the “ten-year failure-free” standard, assuring each air compressor is designed and built to the highest standards of durability and reliability.

Energy-saving

We are the forerunner of energy-saving technologies in the industry. We launched our first VSD oil-injected air compressor in 2004 and drafted China’s industry standard for VSD Oil-injected and PM VSD Screw Air Compressors. In 2015, we launched two-stage PM VSD air compressors. Our products have won the "Energy Efficiency Star" awarded by the Ministry of Industry and Information Technology (MIIT) for five consecutive years. In 2024, we were honored as "Compressed Air System Energy Saving Outstanding Contributor" by the China General Machinery Industry Association (CGMA), the only Chinese air compressor manufacturer awarded along with multinational corporates.

Smart

Each Deman air compressor is equipped with “Deman Cloud” intelligent remote monitoring and control system to continuously monitor and ensure the safe running of each installed machine. Additionally, Deman self-developed “Air Commander” multi-compressor central control system is able to optimize the energy efficiency of the entire installation by automatically calculating and adjusting the optimal load for each air compressor.

Customized Air Pressure

Deman’s self-developed intelligent variable frequency constant pressure control system can accurately control the output air pressure according to the customer’s production requirement. The system is able to maintain the output air pressure within the range of ±0.002MPa, which effectively reduces the energy consumption of the whole compressor. Deman holds the Invention patent of "Intelligent Variable Frequency Screw Air Compressor Control System".

Customized Air Flow

Deman intelligent variable frequency control system can intelligently output the optimal air flow according to customer’s minimal pressure requirement. In addition, we also offer customized air compressor tailored to specific air flow and air pressure requirement, to ensure optimal operating efficiency under the specified working requirement.

Customized Air Quality

For selected popular compressor models, Deman provides integrated air compressors with after-treatment configurations to meet the air quality requirement of different industries. In addition, our professional sales engineers can provide the tailored after-treatment solution for the compressed air station, to not only meet the air quality requirement, but also low pressure drop and high energy efficiency.

Maximize Return in Compressor Station by Applying Six-end Solutions

We follow six-end solutions to create infinite value for client’s efficient use of compressed air

Compressor Station Planning

"No planning, no machine selling". We make sure to understand the air pressure, air flow, and air quality requirement of each air use terminal at client’s factory, before selling anything. When most customers want to spend less for a better machine, we think it is necessary to invest time in planning, to avoid mismatched system that can reduce production efficiency.

Compressed Air Production

Applying “Three-dimensional Customization”, meaning customize the compressor station in terms of air pressure, air flow, and air quality requirements. By selecting the best combination of Deman air compressors + air dryers + heat recovery unit + “Air Commander” central control system, we make sure customers not only has improved production quality, but also reduced energy consumption.

Compressed Air Transmission

In order to make customers’ life easier, we established a professional team for designing and installing air pipe networks using Deman energy-saving aluminum alloy or stainless-steel green air pipe. Our scientific design, green materials, and professional installation ensures efficient air transmission with minimal pressure drop.

Compressed Air Application

Pneumatic components, as the key parts of automation equipment, play a crucial role in the production quality and efficiency. For this reason, we advise customers to select high-quality pneumatic components, pressure control valves, flow control valves, and pneumatic tools, to help our customers optimize the application of compressed air, improve air use efficiency of and reduce energy consumption.

Remote Management

We ensure production safety by using cloud-based early warning systems. If operational metrics of our air compressors deviate from set values, the system promptly send alerts to mobile terminals. We then offer proactive maintenance to prevent potential failures and production interruptions for our customers.

After-sales Service

Our service motto is to "put customers' interests first and take pride in delighting customers"! In order to maximize customer return in the ten-year life cycle of air compressor, we suggest to have “comprehensive maintenance” every 3,000h. Regular maintenance of our air compressors and post-treatment system can ensure the long-lasting efficiency and reliability of installed units.

Industrial Application

Our products are broadly applicable to textile, hardware, plastics, automotive, home appliance, thermal power, and many more industries
