Intended use:
It is recommended to install air grilles with filter material to protect equipment, located inside electrical cabinets, from dust, dirt and some liquids. Air grilles are simple and easy to maintain. They can be used separately on their own as well as together with an axial flow fan to provide additional cooling.
Design features:
Essima air grilles are convenient in mounting as you can install them on the cabinet wall by means of snap-on mechanism. The grilles are made of light grey (RAL7035) or black (RAL9011) ABS plastic. Thanks to the usage of a rubber seal, the grilles provide high-level protection from liquids. Some models have curved lamels in the shape of an arch, which creates additional protection from rainwater that might get inside the cabinet. Filter material installed in the grilles stops particles with a size more than 10 micron from getting on the equipment. In case of filter clogging it can be easily replaced.
Main features:
- Two color options – RAL7035 (light grey) and RAL9011 (black).
- There are models with straight as well as curved lamels.
- Built-in rubber seal.
- Protection stage – IP54.
- Easy replacement of filter material.
- Fixing by snap-on mechanism (except for the STFL series).
