Danfoss FIA 32 straightway strainer housing, 32 mm (1 1/4 in) butt weld ASME B 36.10M Schedule 80, 52 bar, steel (code 148B5552)

Danfoss FIA 32 strainer (filter) housing for the SVL Flexline industrial-refrigeration range, store code 148B5552, straightway body. The FIA holds a replaceable strainer insert that protects downstream components from dirt and weld slag during commissioning and operation; the insert is exchanged through a bolted cover. This code is nominal size 32 mm (1 1/4 in) with butt weld connections to ASME B 36.10M Schedule 80. 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 µ100 plain insert the flow coefficient Kv is about 17.6 m3/h. The FIA INS strainer insert (38/72/100/150/250/500 micron, plain or pleated) is ordered separately. Specifications per Danfoss store code 148B5552.

Compatibility

Danfoss SVL Flexline FIA 32 strainer housing. Pair with a FIA INS strainer insert in the required micron rating (38/72/100/150/250/500, plain or pleated). EN 10220 and ASME weld-end preparations are not interchangeable — confirm the mating pipe schedule before ordering. Shares the SVL Flexline platform with SVA-S/SVA-L shut-off valves and REG regulating valves of the same nominal size.
