Claim 15:
16. An air filtration system comprising:
a housing configured to receive a filter element therein through which a fluid flow passes, the filter element comprising an upstream side and a downstream side; and
a monitoring device comprising:
a first fluid conduit in fluid communication the upstream side of the filter element;
a first pressure sensor, wherein the first pressure sensor is in fluid communication with the first fluid conduit;
a second fluid conduit in fluid communication with the downstream side of the filter element;
a second pressure sensor, wherein the second pressure sensor is in fluid communication with the second fluid conduit;
a third fluid conduit and a third pressure sensor in fluid communication with the third fluid conduit, wherein the third fluid conduit is in fluid communication with a compressed gas supply;
a monitoring device control circuit in electronic communication with the first pressure sensor and the second pressure sensor; and
a housing, wherein the first pressure sensor, the second pressure sensor and the control circuit are all disposed within the housing.
