Bayonet filter housing

Bayonet filters allow a quick and easy change of the filter element, even at high temperatures. They are chemically very resistant due to the materials used. These filter housings can usually be installed in a very space-saving manner, they seal well with a bayonet access. The design allows the filter to be positioned in hot spots, e.g. at gas extraction. They can also be used to heat the filter housing itself using a heater or a heating sleeve.

Heated Bayonet filters

Filter housings equipped with heaters, heating sleeves or insulating sleeves can better maintain a target temperature.

Heating filter housings with heaters or heating jackets are an effective way to prevent liquids from condensing or filters from blocking when temperatures are too low. The heaters or heating sleeves are placed around the filter housing and generate heat that keeps the inside of the housing at a sufficient temperature to ensure proper filtration.

The picture shows an Ex heating sleeve for a bayonet filter.

Both heaters and heating jackets can be manufactured for hazardous areas and adapted to other circumstances, for example weather resistance.

Here you will find details about heaters and heating sleeves.
