Material and Design
Each kit includes a retaining plate and gasket. The rain cover is constructed from epoxy-coated cold-rolled steel plate, a material commonly used in industrial construction due to its exceptional strength and durability. The low edge of the cover features perforations to improve ventilation and provide protection against insect infestation.
The rain covers are compatible with both MDL and M-Series membrane dehumidifiers. To prevent interference between membrane mounting screws and rain cover mounting screws, it is crucial to select the appropriate models as specified in the corresponding table.
