PiTTek personnel have spent many years developing a design for a centrifugal fan to handle rolling mill oil mist/coolant exhaust. We employ single thickness blades in a backwardly inclined arrangement.
There are as many as 30 modifications applied to fans selected for this service.Fans are installed ahead of the final collector. This reduces "spitting" of liquid from fan outlets and optimizes the beneficial effects of inertia on mist collection. Click thumbnails to view larger image
