Nema 4 w. Fan and Filters

Nema 4 w. Fan and Filters

Nema 4 enclosures are seal tight enclosures which are rated for indoor and outdoor use. If we require the cooling for Nema 4 or 4X enclosures we could only do it by expensive methods like air conditioner or vortex coolers. We can not cut any holes in these enclosures to install general purpose cooling fans or filters even using with rain hoods as it can be done for 3R enclosures to provide air flow in the enclosure for cooling. Now there are special Nema 4 rated fan/filter/rain hood kits available from certain manufactures which can be installed in the Nema 4 enclosures which will maintain the same rating and provide cooling. This is very inexpensive way to maintain the rating and still able to provide cooling by fans and filters
