Abstract
In a filter, a rotatable connection flange with two kidney-shaped openings and a diametral web between the openings is located between the top part and bottom part of the filter. Rotating the connection flange allows the direction in which a gas flows through the filter element located in the filter housing to be reversed. In this way, the filter can be operated as a coalescence filter or as a dust filter by simply rotating the connection flange.
Claims36
A filter comprising:
- a housing having a top part and a bottom part, said bottom part having a connection ring;
- a filter element received in the bottom part;
- a rotatable connection flange arranged between the bottom part and the top part of the housing,
- a sealing ring disposed between the connection flange and the connection ring.
A filter, comprising:
- a housing having a top part and a bottom part;
- a filter element received in the bottom part;
- and
- a rotatable connection flange arranged between the bottom art and the top part of the housing, said connection flange provided with two congruent openings arranged as mirror images with respect to one another, wherein one of the openings is connected to an interior of the filter element by a first passageway, and the other one of the openings is connected to an annular space between the filter element and the bottom part of the housing by a second passageway.
A filter, comprising:
- a housing having a top part and a bottom part;
- a filter element received in the bottom part;
- and
- a rotatable connection flange arranged between the bottom part and the top part of the housing, said connection flange provided with two congruent openings arranged as mirror images with respect to one another, wherein the top part of the housing is provided with complementary openings and with an inflow passage and an outflow passage.
A filter, comprising:
- a housing having a top part and a bottom part;
- a filter element received in the bottom part;
- and
- a rotatable connection flange arranged between the bottom part and the top part of the housing, said connection flange provided with two congruent openings arranged as mirror images with respect to one another, wherein the openings in the connection flange are each surrounded by a sealing ring.
A filter, comprising:
- a housing having a top part and a bottom part;
- a filter element received in the bottom part;
- a rotatable connection flange arranged between the bottom part and the top part of the housing;
- and
- an axial condensate line extending from the top part of the housing through the connection flange and having a condensate tube projecting through the filter element.
A filter, comprising:
- a housing having a top part and a bottom part;
- a filter element received in the bottom part;
- a rotatable connection flange arranged between the bottom part and the top part of the housing;
- and
- a level sensor arranged below a free end of the filter element.
A filter, comprising:
- a housing having a top part and a bottom part;
- a filter element received in the bottom part;
- and
- a rotatable connection flange arranged between the bottom part and the top part of the housing,
- wherein the top part of the housing is provided with a positioning pin to engage a positioning opening of the connection flange.
A filter, comprising:
- a housing having a top part and a bottom part;
- a filter element received in the bottom part;
- and
- a rotatable connection flange arranged between the bottom part and the top part of the housing,
- wherein the top part and the bottom part of the housing are connected to a functional block having a differential pressure indicator and a condensate discharge.
A filter element, comprising a connection flange having first and second passages and attached to a top part of a filter housing for rotation between a first position in which the first passage connects an interior of the filter element with an inflow passage of the top part and the second passage connects an annular space of the filter housing with an outflow passage of the top part, and a second position in which the first passage connects the annular space of the filter housing with the outflow passage of the top part and the second passage connects the interior of the filter element with the inflow passage of the top part.
