Galvanized steel filter rack sized for Enertech VS and VT geothermal heat pumps in the 015 through 036 range. The rack accepts either a 1" or a 2" thick filter, so the same accessory covers standard 1" media and thicker 2" filters.

VS and VT are Enertech Global compact vertical packaged water-to-air heat pumps, and Enertech lists an optional 1" or 2" filter rack as an accessory for this cabinet. Mounting the filter in an external rack keeps filter changes out of the unit cabinet.
