Deman Air Compressor: Tops the Energy Efficiency List of the MIIT

In the industrial manufacturing sector, air compressors, as the source of power, are energy-consuming giants. Their energy-saving performance directly affects the operating costs of enterprises. Among numerous brands, Deman air compressors, with their leading technologies and outstanding energy efficiency, have repeatedly won awards and have become the representative of “the most energy-efficient air compressor brand in China”.

• Industry Pioneer: Technological Innovation Leading an Energy Efficiency Revolution

As the inventor of China’s first permanent magnet variable frequency air compressor, Deman’s groundbreaking achievement has caused a significant stir in the industry.

The advent of permanent magnet variable frequency technology has brought unprecedented energy savings and operational stability to air compressors. Traditional air compressors suffer from high energy consumption and unstable efficiency during operation, whereas Deman’s energy-saving permanent magnet air compressor through precise variable frequency control, automatically adjusts the motor speed based on actual air demand, thereby greatly reducing energy consumption. Deman’s independently developed “Permanent Magnet Variable Frequency Two-Stage Compression Technology” has been tested and certified by the national energy efficiency laboratory, achieving a comprehensive energy saving rate of 30% to 50%.

• Standard Setter: Leading the Standardized Development of the Industry

Deman actively participates in the formulation of industry standards and has become a drafter of three major air compressor-related standards.

Deman led the drafting of three key standards: *JB/T10972-2010 Conversion Frequency Oil-flooded Screw Air Compressor For General Use, *JB/T 11420-2013 Low-voltage frequency converters for air compressors and *JB/T13345-2017 Integrated Permanent Magnet Variable Frequency Screw Air Compressor*. These standards serve as crucial benchmarks for evaluating the performance of permanent magnet variable frequency air compressors.

During the drafting process, Deman leveraged its years of industry experience and technical expertise, integrating advanced design concepts, stringent quality requirements, and scientific testing methods into these standards.

• Authoritative Certification: Endorsed by National Honors

Deman’s energy-saving technology has not only been validated by the market but has also repeatedly received national-level recognition. In 2024, Deman Compressor was included in the the National Catalog of Recommended Energy-Saving and Carbon-Reducing Technologies and Equipment in the Industrial and Information Technology Sector (2024 Edition), highlighting its benchmark status in the field of energy saving and carbon reduction.

In the National Catalog of Recommended Industrial Energy-Saving Technologies and Equipment released by the Ministry of Industry and Information Technology, Deman’s permanent magnet variable frequency air compressor has repeatedly ranked first, establishing itself as a nationally recognized benchmark for energy-saving technology. Furthermore, Deman is the only company in the air compressor industry to have obtained the Seven-Star Service Certification.

Deman has also been honored with the “Outstanding Contribution Unit for Compressed Air System Energy Saving” award from the China General Machinery Industry Association and has been recognized as a “National Level 'Little Giant' Specialized and Sophisticated Enterprise.” These accolades fully demonstrate Deman’s comprehensive strength in air compressor energy-saving technology and durability.

• Quality Commitment:10-Year Whole-Machine Warranty(in China)

Deman’s founder, Cen Huanjun, broke industry norms in 2017 by launching the “10-Year Whole-Machine Warranty” (contingent on standardized maintenance), which now covers over 10,000 customers. Deman is the world’s first air compressor manufacturer to offer a “10-Year Whole-Machine Warranty,” a commitment that reflects its ultimate confidence in product quality.

This commitment is underpinned by three pillars: core components from Germany’s GHH-RAND, military-grade assembly processes, and a full lifecycle big data monitoring platform.

Behind this commitment lies Deman’s high level of confidence in its product quality. Deman air compressors utilize high-quality raw materials and advanced manufacturing processes, undergoing strict quality inspections and long-term operational tests to ensure exceptional reliability and stability for each unit.

Currently, a ten-year warranty service is implemented in China. This policy is also being gradually extended to overseas partners with long-term cooperation.

• Service Innovation: A Seven-Star Certified Service System

Deman not only leads the industry in product performance but also continuously innovates in service system development. In 2024, Deman received the industry’s first “Seven-Star Service Certification” from the China Machinery Maintenance Association.

This certification covers 24/7 emergency response, remote intelligent diagnostics, a network of over 500 certified engineers, and 98% spare parts coverage. Deman’s innovative “Compressed Air Hosting Service,” billed based on air consumption, helps companies reduce failure rates by 76%.

Deman provides butler-style service from solution design to after-sales maintenance, with 40 dealer locations and a 26-person professional installation team, supporting 7-day rapid delivery and 24-hour response. Its 10-Year comprehensive maintenance (in China) encompasses full-process services such as regular maintenance, remote diagnostics, and parts replacement, ensuring zero performance degradation over ten years.

• Energy-Saving Case Studies

A packaging materials company in Ningbo replaced its original equipment with the Deman GGV40e permanent magnet variable frequency two-stage compression air compressor, achieving annual electricity savings of 160,000 kWh in its air compressor system.

Deman’s permanent magnet variable frequency air compressors deliver significant annual savings: assuming a standard air compressor consumes 100,000 kWh annually, a Deman energy-saving compressor can save approximately 30,000 to 50,000 yuan in electricity costs.

Deman has served over 10,000 enterprises, including well-known companies like Groupe Bull and Tianma Group, accumulating annual electricity savings of over 200 million kWh and reducing carbon emissions by 180,000 tons. In another case, Zhejiang Xinzhonghe Woolen Company, after adopting Deman air compressors, saved 190,000 kWh of electricity annually and received Jiaxing City’s first Level 1 energy efficiency certification.

As the industrial sector accelerates its green transformation, Deman will continue to delve deeper into energy-saving technology, promoting the evolution of air compressors from “high-energy-consumption equipment” to “intelligent energy-saving systems”, thereby helping Chinese manufacturing achieve a low-carbon future.
