The pumps in the Hiscroll Atex range from Pfeiffer Vacuum meet the requirements of the European directive 2014/34/EU. The Hiscroll Atex conforms to equipment category 3G based on contact with the pumped substance and meets temperature class T4. This allows all gases up to and including explosion group IIC to be pumped. It is even possible to pump hydrogen.
With these properties, the Hiscroll Atex covers many applications in the field of analytics, industry or research & development. Explosion-protected devices are used in many sectors, including industrial processes such as generating and pumping hydrogen. The Hiscroll Atex is also used in laboratories for pumping solvent-based liquids and gases which can produce combustible vapours. The Atex certification is awarded since the Hiscroll Atex has no sources of ignition for potentially hazardous gas mixtures.
