Between the filters, terminals and dampers lies everything else a working installation needs: fresh air, Z-blade and gravity louvers that breathe for the building, door transfer grilles, return air risers between floors, GI plenum boxes and the flexible duct that makes the final connection. Fabricated in the same Surat plant, to the same drawings-first standard.
