After Operation - Vetter LD 50/30 Operating Instructions Manual

A leak in a container or tank is a weak point. Therefore avoid any
additional damage by filling the leak sealer so that no more liquid
or gas escapes. This can be the case at a point lower than the ma-
ximum permissible operating pressure.
9 The attached vacuum leak draining bag is to be continually
monitored.
9 Always make certain that there is sufficient air.
9 After termination of operation, the air supply only needs to be
closed (close the output valve on the pressure regulator).
9 After releasing the vacuum, the bag is detached from the wall
of the tank.
9 Do not let the bag fall otherwise this could damage it.
Example of the air requirement
Compressed air bottle 6 l/300 bar
Input pressure Vacuum
2 bar 0.15 bar
3 bar 0.25 bar
4 bar 0.38 bar
Minimum power of the compressor: 200 l / min. at 4 bar
9 Use a Y-distributor with additional air-supply hose or dual
connector when using a number of compressed air bottles.
9 The vacuum power of the bag can also be increased before
operation by wetting the sealing lip with soap or water.
