Approvals
The Prevost PPS Coupling holds ATEX approval, meaning it is certified for safe use in potentially explosive atmospheres. These are environments where flammable gases, vapours, or combustible dusts may be present.
This coupling is approved for use in Zones 1, 2, 21 and 22, areas where an explosive atmosphere is possible but not continuously present. It is not rated for Zone 0 or Zone 20, where explosive atmospheres exist continuously or for long periods.
