FILTER MODULE WITH FLOW CONTROL

摘要

A filter module and method for facilitating rapid flow setting and/or cost-effective balancing of airflow through a plurality of filters is provided. In one embodiment, the filter module includes at least one port configured to provide a metric indicative of flow through the housing assembly. In various other embodiments, at least one port is utilized for sensing differential pressure across a flow restrictor, such as a damper assembly and/or a diffuser plate of the housing assembly, an orifice plate disposed in a collar or ductwork coupled to collar, and the like. In another aspect of the invention, a method for replacing an air filter is provided that includes the steps of replacing an air filter disposed in a filter housing assembly, and setting a damper position using a damper position indicator to return air flow through the filter to a predetermined rate.
