DORIN S.p.A. has been producing open compressor since 1932. These compressors are constructed with the highest quality materials and are therefore suitable for working in particularly hard conditions. Compressors are designed to offer top performance and special care has been given to have smooth and silent operation. Compressors ranging between 2Q-2 and 51VS are lubricated via a sling disk. Those models can rotate only in a specific rotational sense, clearly marked on the compressor. Compressors ranging between 62VS and 110VS are lubricated via a gear oil pump. Those models can rotate in both senses. All open type compressors manufactured by DORIN can be provided in accordance to Directive 2014/34/EU – ATEX.


ATEX approval is excluding all mechanical components including but not limited to drive belts, inherent cases, and some electric components supplied with the compressor. Each compressor shows following ATEX marking:

II    = Group II machinery

3    = Category 3 (zone 2)

G   = Explosive atmosphere with gas, vapor or fog presence

c    = Protection type for nonelectric equipment (constructive safety)

IIB = gas group

X   = Special conditions for safe use:

• Low mechanical risk

• Tamb: -20°C ÷ +60°C

• Temperature class T3 or T4 according to the working condition. Temperature class can anyway be identified considering the given application, caring about what mentioned in the following application envelopes.
