ATEX certificationThe compressed air stirrers from Buddeberg GmbH are explosion-protected according to the current ATEX regulation 2014/34/EU and are assigned to equipment group II, zone 1 and 2 for gas atmosphere G and/or can be offered for dust atmosphere D too.
Compressed air stirrers of equipment group II include the explosion subgroups IIA, IIB and IIC, and can thus be used for mixing work in these areas.
According to the type, compressed air stirrers are classified in temperature class T4 (max. 135°C) or T5 (max. 100°C). The temperature classes designate the maximum permitted surface temperature of the used appliances in order to avoid ignition by high surface temperatures. The specified temperature class does also include applications for lower T classes (e.g. T5 stirrers are suitable to be used for T1 to T4 too).
Permitted ambient temperature in a potentially explosive atmosphere is -20°C to +40°C.
