Smitsair B.V. drip trays are designed for collecting and draining droplets of water from airflows. Fitting drip trays protects an air-treatment system from moisture and rain ingress.
If you require it, we can also combine drip trays behind our grilles if the permitted airspeed is too high. In this case, the drip tray drains the collected water to the exterior via the lowest blade of the grille. This means there is no need to fit additional facilities for drainage through rainwater pipes.
