ATEX certification information
Temperatures
• The maximum surrounding temperature for which the certification is valid
is 40°C.
• 40°C is also the maximum allowed temperature of the compressed air when
it enters the product.
• If the product is installed in an equipment, the entire equipment has to corre-
spond to the guidelines 2014/34/EU.
• Make sure that the compressed air fulfil our quality demands (quality
classes 2.4.3. and 3.4.4 respectively 3.5.4 acc. to ISO/DIS 8573-1).
• Do not exceed maximum pressure of 6.3 bar, or as stated on the product
nameplate. Exceeding the operating pressure can increase the surface tem-
perature due to higher rotating speed and the product can become an igni-
tion source.
