Danfoss FIA 25 straightway strainer housing, 25 mm (1 in) ANSI/ASME B1.20.1 NPT, steel, 52 bar, cover (code 148B5449)

Danfoss FIA 25 strainer (filter) housing for the SVL Flexline industrial-refrigeration range, store code 148B5449, straightway body. The FIA holds a replaceable strainer insert that protects downstream components from dirt and weld slag during commissioning and operation. The strainer insert is exchanged through a bolted cover. This code is nominal size 25 mm (1 in) with NPT connections to ANSI/ASME B1.20.1. Steel housing for R717 (ammonia), R744 (CO2) and fluorinated refrigerants and their oils. Maximum working pressure 52 bar (754 psig); media temperature range -60 to 150 C (-76 to 302 F). With the u100 plain insert the flow coefficient Kv is about 10.5 m3/h (Cv ~60.76 gal/min). The FIA INS strainer insert (38/72/100/150/250/500 micron, plain or pleated) is ordered separately. Specifications per Danfoss store code 148B5449. Used in commercial refrigeration, provision-room cooling and reefer plant rooms across HFC, HFO and CO2 (R744) refrigerants.

Compatibility

Danfoss SVL Flexline FIA 25 strainer housing. Pair with a FIA INS strainer insert in the required micron rating (38/72/100/150/250/500, plain or pleated). Danfoss SVL Flexline FIA 25. Shares the SVL Flexline platform with SVA-S/SVA-L shut-off, REG regulating, SCA-X/CHV-X check and FIA strainer components of the same nominal size. EN 10220 and ASME weld-end preparations are not interchangeable — confirm the mating pipe schedule before ordering.
