A filter indicator system (10) for indicating when air flow through a filter (12) is restricted includes an indicator (26) mounted in a filter assembly (11) downstream of the filter (12). The indicator (26) includes a pop-up member (66), which includes a signal portion (72), which via a moving device (74) moves between a non-signalling position where the pop-up member (66) does not extend noticeably and a signalling position where a signal portion (72) extends noticeably. A pressure responsive releasing mechanism (82) is associated with the pop-up member (66) for initially holding the pop-up member (66) in the non-signalling position and preventing movement by the moving device (74), and for subsequently releasing the pop-up member (66) when the pressure drop across the filter (12) reaches a predetermined value.

Système indicateur (10) destiné à indiquer si l'écoulement d'air dans un filtre (12) est limité et comprenant un indicateur (26) monté dans un ensemble filtre (11) en aval du filtre (12). L'indicateur (26) comprend un élément d'éjection (66) comportant une partie de signalisation (72) et qui, par l'intermédiaire d'un dispositif de déplacement (74), se déplace entre une position de non signalisation dans laquelle l'élément d'éjection (66) ne s'étend pas de façon perceptible et une position de signalisation dans laquelle une partie de signalisation (72) s'étend de façon perceptible. Un mécanisme de libération (82) sensible à la pression est associé à l'élément d'éjection (66) et permet de retenir d'abord l'élément d'éjection (66) dans la position de non signalisation et d'empêcher le déclenchement du dispositif de déplacement (74), puis de libérer l'élément d'éjection (66) lorsque la chute de pression dans le filtre (12) atteint une valeur prédéterminée.
