To fellows in hot air business (say air sensing, pneumatics) , one better and cheaper than Air-Logic, insertable (& serviceable) straight inside of air lines, i found with Capstan P: http://www.capstanpermaflow.com/ssdiscpr1.html http://www.capstanpermaflow.com the advantage is it keeps virtually intact existing air volume/bent/length specs; thus doin' a hell of a work in minimal space, allows with gradual grading of filtrating grades sequence even for clogging .
