GS couplings are suitable for the use according to EC standard 94/9/EC.
1. Industry (with the exception of mining)
• device class II of category 2 and 3 (coupling is not approved for device class 1)
• media class G (gases, fogs, steams), zone 1 and 2 (coupling is not approved for zone 0)
• media class D (dusts), zone 21 and 22 (coupling is not approved for zone 20)
• explosion class IIC (explosion class IIA and IIB are included in IIC)

Explanation:
The maximum surface temperatures result from each the maximum permissible ambient or operating temperature T
a
plus the
maximum temperature increase ∆T of 20 K which has to be taken into account.
1) The ambient or operating temperature T
a
is limited to + 90 °C due to the permissible permanent operating temperature of
the elastomers used.
2) The maximum surface temperature of 110 °C applies for the use in locations which are potentially subject to dust explosion,
too.

In case that the operating temperature changes it is absolutely necessary to verify the
coupling selection (see ROTEX
®
GS catalogue).
2. Mining
Device class I of category M2 (coupling is not approved for device category M1).
Permissible ambient temperature - 30 °C to + 90 °C.
