GRAVITY LOUVER (GL)
DESCRIPTION:
Aluminum Gravity Louvers (GL) grilles are intended for exhaust ventilation systems and used as a non-return air valve for automated closing of openings and switching off the ventilator.
Grilles are fitted with easily rotating aluminum louvers, mounted in a frame. Louvers are installed in such a way that when the ventilator is switched off they are closed by gravity. Grilles are mounted in air ducts by means of spring-loaded clamps fitted on side walls of grilles.
