PROBLEM TO BE SOLVED: To improve the working efficiency by fixing an FRL(Filter Regulator Lubricator) unit to an arbitrary place close to a working site. SOLUTION: In a fitting device 11, two suspension parts 12b, 13b are extended downward with a clearance therebetween from horizontal bracket parts 12a, 13a screwed to an FRL(Filter Regulator Lubricator) unit 1, and a foamed urethane rubber 14 is affixed to an inner surface of the two piece of suspension parts 12b, 13b. The FRL unit is inserted in the middle of an air hose piping line, and for example, by fixing the FRL unit by holding a frame of an air hose drum, a beam at a work site, etc., by the two suspension parts of the fitting device 11, the pneumatic pressure can be adjusted, and water can be drained close to the work site.
