Abstract

A filter device for compressed air in which the filter packings can be easily and quickly replaced. A first packing is accommodated in a first sleeve, a second packing is accommodated in a second sleeve, and an inlet passage portion defines an inlet passage for introducing compressed air from the exterior to the first sleeve. A guide passage portion defines a guide passage for guiding compressed air from the first sleeve to the second sleeve, and an outlet passage portion defines an outlet passage for discharging the compressed air out of the second sleeve to the exterior. The first and second sleeves, the inlet passage portion, the guide passage portion and the outlet passage portion are integrally formed of a synthetic resin, thus forming a unitary body for the filter device. The body contains access openings through which the first and second packings are independently removable, and a closure member is removably attached to each access opening to close the access opening and provide fluid-tightness.
