Abstract
A filter for compressed air systems is provided. The filter includes a filter housing with a filter therein between an air inlet and an air outlet. Compressed air flowing between the air inlet and the air outlet passes through the filter housing and the filter element. A base is removably fastened to the filter housing which may be separated from the filter housing to allow the filter element to be removed and replaced.
Claims21
-20. (canceled)
A filter for a compressed air system, comprising:
- a filter housing;
- a base enclosing one end of the filter housing, the filter housing and the base defining an enclosed space configured to house at least one filter element;
- an air inlet and an air outlet defined by the filter housing or the base, wherein the air inlet is configured to be in fluid communication with a first side of the at least one filter element and the air outlet is configured to be in fluid communication with a second side of the at least one filter element such that airflow from the air inlet to the air outlet passes through the at least one filter element;
- a first valve fluidly coupled to the air inlet and the air outlet, the first valve configured to selectively control whether airflow from the air inlet is directed to the enclosed space for filtering by the at least one filter element or directed to the air outlet and thereby bypass the enclosed space;
- a second valve fluidly coupled to the air inlet and the enclosed space;
- a third valve fluidly coupled to the enclosed space and the air outlet,
- wherein closure of the second valve and the third valve while the first valve is open allows for removal of the at least one filter element from the enclosure without interrupting the airflow from the air inlet to the air outlet.

- wherein closure of the second valve and the third valve while the first valve is open allows for removal of the at least one filter element from the enclosure without interrupting the airflow from the air inlet to the air outlet;
- and
- an air dryer for removing moisture from the compressed air,
- wherein the at least one filter element is disposed on an inlet side of the air dryer to thereby filter the compressed air before the compressed air flows through the air dryer.
