Detection phase
The concentration at the filter exhaust must
be lower than 1% of the TLV, and the automatic
saturation detector must warn the user
The concentration at the filter exhaust
must be lower than 50% of the TLV
Safety operation phase
The concentration at the filter exhaust must be
lower than 50% of the TLV ; its duration must
not be lower than 1/12 of the normal operation
phase duration.
It is defined by the filter capacity to retain noxious molecules manipulated within
the enclosure and qualifies the quality of the recirculated air at the filter exhaust.

* : The particulate filter must be at least of H14 type according to the NF EN 1822-1 standard
** : The filters for vapours must be submitted to two successive performance tests with Cyclohexane and Isopropanol for the filters designed to retain
Volatile Organic Compounds (VOC). Another test for the acid vapours is carried out with Hydrochloric acid.
