R5 RE are explosion pressure resistant rotary vane vacuum pumps. They have been specially designed to extract explosion-endangered gas/air and vapor/air mixtures.

These vacuum pumps are certified in accordance with directive 2014/34/EU for II 1G h IIB3 T4 Ga inside and II 2G h IIB3 T4 Gb outside the vacuum pump.

Their ATEX certification makes them suitable for the extraction of almost all materials in the IIB3 explosion group. They can also be used for the extraction of petrol vapor.

R5 RE series vacuum pumps are driven by a directly flange-mounted explosion-proofed electric motor. They come with flame arresters as standard.
