1. A filtration system comprising:
a filter element mount configured to retain a filter element;
a compressed gas supply;
a valve in fluid communication with the compressed gas supply, wherein opening the valve results in a pulse of gas directed at the filter element;
a control circuit configured to control the valve;
a communications circuit;
wherein the communications circuit receives data related to an anticipated change impacting the filtration system, the anticipated change data comprising at least one of data regarding an anticipated change in filtration performance; and
data regarding an anticipated change in filtration system demand;
wherein the control circuit is configured to initiate opening the valve in response to a data input indicating that a pressure drop threshold has been crossed;
wherein the control circuit is further configured to adjust the pressure drop threshold based on the anticipated change data.
