Abstract
An in-line filter device including a partition member, and a lower housing and an upper housing which are held in a fluid communication with each other through at least one intermediate passage formed through the partition member. The lower housing has a radially inner and a radially outer filter having respective packings, for separating vapor and/or liquid particles in compressed air, and accommodates a draining device for discharging the trapped vapor and/or liquid particles. The upper housing has a mist filter of an annular porous structure for further separation of the remaining vapor and/or liquid particles in the compressed air, and an air collector disposed inside the mist filter, for delivering the filtered air.
