Capacities

The full lift capacities for safety valve sizing purposes is 0.21 Kvs.

Performance selection (with primary pressure 10 bar)

For any specified primary filtration pressure, there is a maximum recommended air flowrate. Keeping within this, will ensure that the

element performance maintains the stated high efficiency levels.
