Compact module •The main dimensions (width and depth) ofF.R.L. devices have been integrated into a com-pact module. Accurate assembly dimensionsare obtained with simple calculation. Long-life element •This element incorporates CKD's originalchemical fiber structure (patent pending), whichhas a rough surface and gradually becomesfiner toward the inside. Clogging is greatly re-duced, and the element life is greatly extended.There is no worry of rust forming. Embedded pressure gauge for saving space •The conventional protruding pressure gaugewasted space on the front, and endangeredpersonnel. A neat design and safety have beenrealized by embedding the pressure gauge intothe body.
