Rittal’s newly redesigned rain hoods allow for the of low cost fan cooling in any environment including harsh chemical and wash-down locations.  Rittal’s fan & filter rain hoods are available in powder coated carbon steel offering NEMA 3R and NEMA 4 protection.  The powder coated versions are RAL 7035 (light grey) blending in with colour and texture of Rittal’s line of industrial enclosures. 

The stainless steel version offers NEMA 4X protection. The surface of the rain hood is a #4 brushed surface matching the surface of Rittal’s stainless steel enclosures.

Rittal’s new Top Therm fans and filters provide CSA certified NEMA 12 protection right out of the box.  With the addition of a standard fan & filter rain hood this high level of standard protection can be increased to NEMA 3R, 4 or 4X.  The fan & filter rain hoods install over top of the standard Top Therm fan and filter units and can be easily done as a field retrofit. Installation is a simple matter of drilling 4 holes and fastening the hood’s mounting bracket to the side of the enclosure.  The hood slides over and clips in to the mounting bracket.  The blue silicon gasket makes a tight seal with the surface of the enclosure to maintain the required NEMA protection level.  Be it NEMA 3R, 4 or 4X.

There is a blue silicone gasket gasket that provides the NEMA rated seal to the enclosure.  This blue silicon material is easy to clean and makes it easy to see any contaminants left behind after the wash down process.
