AIR CLARIFICATION FILTER FOR SEALED WALL-NICHE TOMBS OR MORTUARY VAULTS

摘要

The invention relates to an air clarification filter for sealed wall-niche tombs or burial vaults. Said filter comprises an air intake duct (3) with an ultrasensitive nonreturn valve (4) and a translucent tube (1) which is joined to an evacuation duct (2) and which contains a deodorizing and disinfectant liquid (7), through which gas flows from the mortuary cell under the effect of a natural overpressure as a result of the action of a plunger (8) with a mineral filter (9) leading into said liquid and being connected to an end-piece (10) leading into the mortuary cell. The inventive device clarifies the air escaping from mortuary cells such as single or double or battery-type vaults and enables the penetration of outer air.
