*Note 1) The drain guide is NPT1/8 (applicable to the AFM20-A, AFD20-A); and NPT1/4 (applicable to the AFM30-A, AFM40-A / AFD30-A, AFD40-A). The auto drain port comes with a ø3/8 (diameter 3/8 mm) one-touch fitting (applicable to the AFM30-A, AFM40-A / AFD30-A, AFD40-A).
*Note 2) The drain guide is G1/8 (applicable to the AFM20-A, AFD20-A); and G1/4 (applicable to the AFM30-A, AFM40-A / AFD30-A, AFD40-A).
*Note 3) Brackets are not assembled and are supplied loose at the time of shipment. Mounting screws (2 pcs.) included.
*Note 4) When pressure is not applied, condensate which does not start the auto drain mechanism will remain in the drain bowl. Therefore manual release before ending operations is recommended.
*Note 5) If the compressor used is small (0.75 kW, discharge flow rate is less than 100 L/min [ANR]), air leakage from the drain cock may occur when operations start. As such an N.C. type is recommended.
*Note 6) For chemical resistance of the bowl, refer to the table below "Effects of atmosphere of organic solvents and chemicals and where these elements are likely to adhere to the equipment. Chemical data for substances causing degradation (Reference)."
*Note 7) A bowl guard is provided as standard (polycarbonate).
*Note 8) A bowl guard is provided as standard (nylon).
*Note 9) Does not include a valve function.
*Note 10) Thread type: NPT is applicable. Under new Japanese measurement laws, this product is only available for sale outside of Japan (SI units are used in Japan).
*Note 11) ○ is for thread type NPT only.
*Note 12) Float type auto drain: Cannot be selected in combination with C, D.
*Note 13) Metal bowl: Cannot be selected in combination with 2, 8.
