GB / Vortex blower for blowing and suction
GB is a ring-blower family offered in single-stage and double-stage configurations. The catalogue separates blowing and suction applications and provides airflow, pressure and vacuum data by model. Its direct-mounted impeller arrangement makes it a different air-moving technology from the RL three-lobe Roots blower.
Use the selected stage and model curve to check airflow at the required pressure or vacuum. The catalogue maxima are not a combined operating point.
Series catalogue ↗Series overview
The GB catalogue describes a vortex air pump whose impellers are mounted directly on the motor shaft. It lists single-stage and double-stage ranges, each with its own pressure, vacuum and airflow envelope. Applications include combustion air, drying, aquaculture and wastewater aeration, pneumatic conveying and several industrial suction duties.
The compression principle and performance tables should be used to decide whether a blowing or vacuum duty is appropriate. A model chosen for aeration must also be checked against the diffuser and pipework pressure loss. GB uses a ring-blower design, while RL uses a three-lobe Roots design.
Check the series catalogue for the selected configuration.
50 Hz operation. The catalogue lists single-phase 220–240 V models up to 2.2 kW and three-phase 380–415 V models from 0.55 kW. Select the blowing or suction duty from the correct single-stage or double-stage curve. Confirm the gas and installation conditions for the selected configuration; the brochure does not specify a gas-temperature limit.
Yes. The catalogue lists blowing and suction applications. Select from the performance data for the required pressure or vacuum duty.
Choose the stage arrangement from the required airflow and pressure or vacuum. The catalogue provides separate single-stage and double-stage ranges.

Choose the blower by the gas, required airflow and pressure or vacuum, drive and installation conditions.
RL is a three-lobe Roots blower family with separate pressure and vacuum configurations in its catalogue. The document distinguishes blower body, complete pressure set and complete vacuum set codes. Its rotor arrangement and accessory options suit aeration and industrial air duties where the selected airflow and pressure are verified.
