Claims22
A filter assembly, comprising:
- a casing extending between a top portion and a bottom portion, the casing defining an interior chamber;
- a filter medium disposed within the interior chamber of the casing;
- a vent system positioned at the top portion of the casing, the vent system comprising
- an inner standpipe defining a channel that is contiguous with the interior chamber of the casing;
- an outer check valve comprising a sidewall and an end wall, the sidewall of the outer check valve extending around the inner standpipe such that the inner standpipe is at least partially received within the sidewall of the outer check valve, the end wall of the outer check valve mounted to the sidewall of the outer check valve such that the end wall of the outer check valve is positioned over the inner standpipe;
- an outer standpipe extending around the sidewall of the outer check valve;
- a cover comprising a sidewall and an end wall, the sidewall of the cover extending around the outer standpipe, the end wall of the cover mounted to the sidewall of the cover such that the end wall of the cover is positioned over the outer standpipe;
- and
- an inner check valve, the inner check valve comprising:
- a float positioned at the interior chamber of the casing;
- a valve body mounted to the float and positioned within the channel of the inner standpipe;
- and
- a retainer mounted to the inner standpipe, the valve body vertically movable on the retainer such that the inner check valve is adjustable between an open position and a closed position, the valve body blocking fluid flow from the interior chamber of the casing via the channel of the inner standpipe when the inner check valve is in the closed position.
