PRODUCT CENTER

Greentech International (Zhangqiu) Co., Ltd. is a professional side channel blower supplier. The 2RB 920-7HH27 Side Channel Blower is designed to provide stable airflow, reliable performance, and energy-efficient operation for a wide range of industrial applications.

The impellers in the G_series machines are mounted directly on the motor shaft for non-contact compression entirely without friction. Maximum operational reliability, even at high differential pressures, is ensured by the arrangement of the bearings outside the compression chamber.

The gas is taken in through the inlet. As it enters the side channel, the rotating impeller imparts velocity to the gas in the direction of rotation. Centrifugal force in the impeller blades accelerates the gas outward and the pressure increases. Every rotation adds kinetic energy, resulting in a further increase of the pressure along the side channel. Near the exit, the side channel narrows at the rotor, sweeping the gas off the impeller blades and discharging it through the outlet silencer where it exits the side channel blower.

Advanced Design & Performance of Side Channel Blowers

Efficient Air Compression Technology

Multi-Stage Energy Transfer

As air enters the side channel, the high-speed impeller continuously transfers kinetic energy to the gas. The air circulates repeatedly through the side channel, allowing pressure to increase gradually with each rotation. This efficient compression process provides stable airflow for both pressure and vacuum applications.

Stable Pressure Generation

The blower builds pressure continuously as air moves through the side channel rather than compressing it in a single stage. This ensures smooth airflow, stable pressure, and reliable performance under different operating conditions.

Continuous and Pulse-Free Airflow

The optimized impeller and side channel design reduce airflow pulsation and pressure fluctuations, delivering a steady air supply for applications that require consistent performance.

Reliable Mechanical Structure

Contact-Free Compression Chamber

The impeller is mounted directly on the motor shaft and rotates without contacting the housing. This contact-free design minimizes internal wear and helps ensure long-term reliability.

External Bearing Design

Bearings are positioned outside the compression chamber, protecting them from heat and contaminants. This arrangement improves cooling performance, extends bearing life, and supports stable continuous operation.

Efficient Cooling and Longer Service Life

Lower operating temperatures help extend grease life, reduce maintenance requirements, and increase the overall service life of the blower.

Performance Advantages

Clean, Oil-Free Air Supply

The compression chamber requires no lubrication, producing completely oil-free air. This makes the blower ideal for wastewater treatment, aquaculture, food processing, medical equipment, and other clean-air applications.

Low Noise and Smooth Operation

Precision-balanced rotating components and an integrated silencer reduce vibration and operating noise while maintaining stable airflow.

Compact Structure and Easy Installation

Its compact design saves installation space and allows easy integration into a wide range of industrial systems. The durable housing also provides excellent reliability and corrosion resistance.

Low Maintenance and Continuous Operation

Reduced Maintenance Requirements

With few wearing parts, an oil-free compression chamber, and long-life bearings, the blower requires only simple routine maintenance, reducing downtime and operating costs.

Designed for 24/7 Continuous Duty

The robust structure and efficient cooling system allow reliable 24/7 continuous operation under rated working conditions, providing stable airflow and dependable performance for demanding industrial applications.
