Nagoya, the capital of Aichi Prefecture, stands as the center of Japan’s manufacturing and heavy industry sectors. From automotive assembly lines to petrochemical refining and bulk transport along the busy Port of Nagoya, the area's energy consumption is heavily audited under national decarbonization targets. Low-pressure air systems—particularly conventional Roots blowers—have long been identified as prime areas for energy optimization.
By switching from traditional positive displacement Roots blowers to dry-running oil-free screw blowers, facilities in the Chukyo Metropolitan Area can reduce energy use by up to 35%. Our specialized screw blowers use internal compression structures rather than external compression, providing continuous, pulse-free airflow with much lower Specific Energy Consumption (SEC). This technology directly supports local initiatives for net-zero manufacturing.
Precision-engineered asymmetric helical profiles spin without contacting each other. This eliminates the need for oil lubrication inside the compression chamber, ensuring 100% oil-free air delivery (ISO 8573-1 Class 0).
Unlike Roots blowers that release air against system backpressure, screw rotors compress the air progressively within the housing. This significantly reduces discharge pulsation, reduces system vibration, and extends pipeline life.
Our Permanent Magnet (PM) synchronous motors adjust operating speed dynamically to match actual air demand. This eliminates typical idling losses and matches fluctuating aeration rates in industrial processes.
Industrial buyers in Japan and globally are moving away from single-source supply lines to build more resilient networks. Shanghai Honest Compressor Co., Ltd. (founded in 2004, Jiading District, Shanghai) combines British twin-screw engineering standards with the efficiency and scale of Chinese manufacturing (Industry 4.0). By using high-precision CNC rotor milling, advanced balancing equipment, and multi-stage testing bays, we deliver high-reliability screw blower systems that meet European CE and ISO certification standards at competitive pricing.

Recent industry reports estimate the global dry vacuum pump and low-pressure blower market at US$ 5.97 billion in 2024. The market is projected to grow from US$ 6.17 billion in 2025 to US$ 8.28 billion by 2034, registering steady growth.
This growth is driven by increasing demand for contamination-free processes. Industries such as semiconductor manufacturing, high-purity chemicals, lithium-ion battery production, and municipal water treatment are moving away from oil-lubricated components. Our dry screw blowers and vacuum pumps help eliminate the risk of oil contamination while maintaining reliable operation.
Roots blowers are external-compression machines, pushing air against the system pressure, which creates high backpressure losses. In contrast, screw blowers feature internal compression. The air volume is progressively reduced as it travels along the helical screw profile, which matches the target outlet pressure more closely. This reduces energy consumption by up to 35%, depending on the operating pressure.
Class 0 certification guarantees that there is zero oil in the air stream. In processes like pneumatic conveying of raw food materials or pharmaceutical handling, oil mist from lubricated compressors can contaminate the end product. Dry screw blowers use non-contacting rotors without lubricants in the compression chamber, ensuring oil-free air delivery.
Municipal wastewater plants experience variable biological oxygen demand (BOD) throughout the day, requiring fluctuating aeration rates. A VSD PM motor dynamically adjusts the screw blower speed to match actual oxygen demand. Permanent magnet synchronous motors maintain high efficiency even when operating at partial loads, reducing energy waste compared to standard fixed-speed AC motors.
We provide full engineering support, including layout drawing design, energy-saving calculations, and customized configuration (PLC programming, specific voltage requirements for Japan such as 200V/400V 50Hz/60Hz, and custom noise enclosures). We also offer virtual pre-shipment inspections and test data logs.
