Model 3300
End-of-Line Vacuum Relief Vent
OBJECTIVE
The Model 3300 vacuum relief vent
is intended for use on storage tanks, vapor recovery systems and process
systems where vacuum relief is required.
TECHNIQUE
Weight loaded pallet on the
vacuum side of the vent allows the intake of air necessary to maintain the tank
pressure within the permissible vacuum limit to avoid damage to the tank. The
model 3300 virtually eliminates the intake of air except during normal tank
inbreathing.
