Duct Mounted Filter Boxes are commonly used for low efficiency filtration applications in spiral wound duct work. Low grade panel or bag filters can offer protection to inline system components such as fans, coils and heaters from dust particles. Various airflows can be supported in all of the standard wound spiral dimensions.
Duct Mounted Filter Boxes are manufactured in galvanised sheet steel and include either a Grade G2 Glass Panel Filter or a Grade G4 General Purpose Bag Filter.
They have a removable lid with closed cell gasket. The unit can be rotated at time of installation to provide side or top access.
