Filter assembly cover with integrated sensors

A filter assembly comprising:

• a filter module including a filter module inlet and a filter module outlet in fluid communication with each other through a filter, a first surface of the filter module having the filter module outlet defined therein;
• a fan module including a fan module inlet and a fan module outlet in fluid communication with each other through a rotatable fan, a first surface of the fan module having the fan module inlet defined therein, the first surfaces of the filter and fan modules extending side by side by side, and the fan module inlet and the filter module outlet being laterally spaced apart from one another;
• an electronics module including a control system;
• a cover movable between an engaged position where the cover engages the first surfaces of the filter and fan modules and a removed position away from the first surfaces, the cover defining a plenum, the cover in the engaged position providing a fluid communication between the filter module outlet and the fan module inlet through the plenum, the plenum directing a flow between the filter module outlet and the fan module inlet along a direction different from a direction of the flow through the fan module inlet and from a direction of the flow through the filter module outlet;
• and
• a sensor located in the plenum and configured to provide information on the flow through the plenum, the sensor communicating with a power source and with the control system at least when the cover is in the engaged position.
