Rheem-Ruud RXHF-21 External Filter Rack 21"

The Rheem-Ruud RXHF-21 External Filter Rack is an add on component meant to enhance the air filtering capacity of HVAC systems. It is particularly designed to work with Rheem-Ruud units. In particular, as an external filter rack, its primary function is to provide a solid and safe support for air filters placed outside the main body. The RXHF-21 is constructed of galvanized steel to withstand the harsh conditions of an HVAC setting. The external filter rack works simply: it enables air filters to be easily installed and also easily fixed, hence creating a high quality air flow within the HVAC system.
