摘要:
A filter for an electronics cooling unit of a telecommunications base station, the electronics cooling unit adapted to receive fresh air into a housing of the cooling unit through an opening communicating with the external environment. The filter includes a structural support configured to be mounted to said housing, a gasket sealingly engaging the structural support and adapted to engage the housing; and a filter media supported by the structural support, the filter media being free of a membrane type layer and including a fiber entanglement selected to prevent ingress of water sufficient to pass a salt fog test consistent with GR-487-CORE and in accordance with ASTM B 117.

A non-V bank filter for an animal confinement application such as for filtering out the porcine reproductive and respiratory syndrome virus (PRRSV) is provided. The filter may be a deep pleat of synthetic filter media with at least a MERV 14 rating and efficiency sufficient to filter out the PRRSV in high air flow applications. The media may be embossed and have spacers to provide for structural support and open filter structure for airflow. The filter can occupy less space and in some embodiments or even less space than a corresponding V-Bank filter with comparable performance.

A filter assembly including a rectangular inlet frame having a rectangular inlet opening to receive a primary filter and optional a prefilter. The filter assembly may include a rectangular outlet frame and a housing body that is collapsible to have a flattened shipping state and an erect state. The rectangular inlet frame may also be used as a housing by itself to support and house primary filters and prefilters. A gridwork including one or more grid dividers may be used in the rectangular inlet frame to provide 2 or more openings for receipt of filters.
