The length of separation is sufficient to achieve maximum air circulation within the room. Multiple supply grills may be used to achieve more extensive air circulation requirements. The main filter compartment consists of a sheet metal cabinet housing containing motor, blower, filters, and hinged filter access door that also serves as a return grill for air to enter unit for filtration. The flexible insulated hose is connected to the main filter compartment by the use of a hose collar and secured by the use of hose clamps to achieve an air tight connection.
