LLA2500-L-ATEX
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 correspond 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 respec-
tively 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 temperature due to higher rotating speed and the prod-
uct can become an ignition source.
Ex Classification
If the product is part of an assembly where the components have different Ex classification, the compo-
nent with the lowest level of safety defines the Ex classification of the complete assembly.
