Ring Blower GREENCO 2RB-910 Series Each G-2RB type can be applied both as vacuum pump and compressor in continuous operation over the total stated performance curve range. The motors are available as standard for the input voltage range of 50 and 60 Hz and for protection category IP 55 as well as approbated for UL and CSA.
The GREENCO 2RB-910 Series Ring Blower is a single-stage ring blower (side channel blower) engineered for industrial applications that require higher pressure or stronger suction. Powered by a 3-phase 380V motor, it is easy to install, simple to maintain, and well suited for continuous duty in plant systems.
The 2RB-910 series supports both pressure (blowing) and vacuum (suction) operation, depending on the sub-model. With multiple motor sizes and both 50/60Hz options, it’s easier to match performance to real site requirements.
The blower housing is made from die-cast aluminum—durable yet lightweight—with a compact form factor and low operating noise. It also features an oil-free design, reducing contamination risk and making it ideal for processes that require clean air and long-term system stability.

A ring blower (side channel blower) is designed to generate medium-to-high pressure or vacuum (in mbar) with relatively stable airflow. It is commonly used for aeration, pneumatic conveying, and industrial vacuum handling.
In principle, side channel blowers can be used for both vacuum (suction) and pressure (blowing). However, airflow and pressure/vacuum levels depend on the specific sub-model and the installation conditions, so selection should be based on the required specifications.
Oil-free operation reduces the risk of oil contamination in the air stream. This is especially important for clean processes such as food, packaging, and applications where air quality affects product quality or system reliability.
Select the specification that matches your site’s power frequency. Using the correct frequency ensures the blower speed and performance align with the designed operating conditions.
Yes. It is commonly used for aeration applications that require steady airflow and continuous operation. Selection should consider both the required pressure (based on diffuser depth and losses) and the required airflow (based on basin size and process demand).
Prepare the required airflow (m³/h), required pressure/vacuum (mbar), application type (aeration / conveying / vacuum handling), power frequency (50/60Hz), and installation conditions. This will help identify the most suitable model.
