Included herein are filtration systems that can proactively pulse clean filter elements in response to anticipated changes, such as anticipated changes in filtration performance or anticipated changes in filtration system demand. In an embodiment, a filtration system is included having a filter element mount for a filter element, a compressed gas supply, and a valve, wherein opening the valve results in a pulse of gas directed at the filter element. A control circuit can control the valve. A communications circuit can receive data related to an anticipated change, such as data regarding an anticipated change in filtration performance and/or data regarding an anticipated change in filtration system demand. The control circuit can execute operations based on the anticipated change data such as adjusting a pressure drop threshold and initiating proactively opening the valve in the absence of a pressure drop threshold being crossed. Other embodiments are also included herein.

The filtration system of any of claims 1-4 and 6-27, the data regarding an expected change in environmental conditions comprising ambient humidity data.
The filtration system of any of claims 1-5 and 7-27, the data regarding an expected change in environmental conditions comprising wind speed data.
The filtration system of any of claims 1-6 and 8-27, the data regarding an expected change in environmental conditions comprising an expected sand storm.
The filtration system of any of claims 1-7 and 9-27, the data regarding an expected change in environmental conditions comprising a local sunrise or sunset time.
The filtration system of any of claims 1-8 and 10-27, the data regarding an expected change in environmental conditions comprising atmospheric precipitation.
The filtration system of any of claims 1-9 and 11-27, the data regarding an expected change in environmental conditions comprising expected fog.
The filtration system of any of claims 1-10 and 12-27, the data regarding historical filtration performance of the filtration system comprising instances of a measured pressure drop crossing a threshold value.
The filtration system of any of claims 1-11 and 13-27, the data regarding historical filtration performance of the filtration system comprising daily, weekly or monthly filtration performance patterns.
The filtration system of any of claims 1-12 and 14-27, the data regarding an anticipated change in filtration system demand comprising weather forecast data.
The filtration system of any of claims 1-13 and 15-27, the data regarding an anticipated change in filtration system demand comprising solar radiation forecast data.
