Panasonic Home & Environment Co. launched a new line of WhisperSupply-Wall fans. The company says the filtered fans specifically meet ASHRAE 62.2 requirements for makeup/supply air. The wall-mounted models are equipped with an interior deflector that pushes airflow up and around the walls to avoid drafts. Designed for 6-inch ducts, the WhisperSupply-Wall FV-04WS1 model may be set to either 20 or 40 cubic feet per minute and is ideal for weatherization efforts and addressing combustion appliance zone depressurization, officials say. The units can be wired to work simultaneously with the furnace blower to supply air when it is needed. WhisperSupply was also developed for meeting green building codes by supplying fresh air into smaller areas such as hallways or bedrooms.
