Our range of RG 100 to RG 800 compact fans ensures a healthier environment by extracting and propelling the altered air present in your workspaces.
RG series: operation and use of exhaust fans

RG Series fans (100, 200, 300, 400, 500, 600, 700, 800) are the ideal solution for extracting dust, industrial fumes and other pollutants generated by your production units. They allow purified air to circulate and depressurize. Versatile and compact, the system draws in air by creating a vacuum at the fan inlet (rotation of the impeller) thanks to an electric motor inside the casing. The box channels and propels the air sucked in towards the outlet (outside) to evacuate it from the workspace. The RG series can vacuum one or more workstations/machines at a time.
For what purpose? This equipment is ideal for all types of industry, and is capable of extracting dusts, gases, odors and fumes. They can be fitted with filters to capture fine particles.
What are the technical specifications of OberA suction fans?
The RG range offers a choice of motor performances from 0.55 kW to 7.5 kW. This allows you to find the extraction fan model best suited to your surface area.
To further resist the risk of corrosion and dust-related damage, the fans are made from robust materials, and are available in a stainless steel version for the food industry (optional). Another option is a spark-proof version for activities that generate flammable dust.
Good to know: our extraction solutions can be combined with our capture evacuation systems. Depending on your needs (type of pollutant, surface area, sector of activity), we’ll advise you on the best possible combination to guarantee the best possible extraction and air renewal.
In terms of dimensions, the RG 100 to RG 800 fans require a small footprint: from L535 x W450 x H480 for the most compact version to L820 x W1,000 x H1,198 for the largest model, they remain space-saving pieces of equipment. For worker comfort, they also offer a low noise level of 83 dB(A) to 84 dB(A).
