APM plenum fans provide high efficiency while maintaining a compact size. This is an excellent selection for retrofit and replacement applications and in variable air volume systems. It uses a bolt together framework that is either galvanized or coated. The APM has the same high efficiency / low sound 12-blade wheel as the APH plenum, but at a cost effective price for light and medium duty applications. APM units are available in belt and direct drive with basic accessory options.
