Castair C-FM14 Mini Particulate Filter -- 1/4-inch NPT, 38 CFM, 150 PSI, 5 Micron
The Castair C-FM14 is a 1/4-inch NPT mini particulate filter rated for 38 CFM at 150 PSI maximum with a 5-micron element and a 1.5 oz bowl. It is the smallest filter in the Castair air treatment lineup, designed for low-flow instrument air drops, pneumatic control lines, and 1/4-inch NPT connections where bulk particulate removal is needed before air reaches sensitive equipment.
The C-FM14 removes rust, pipe scale, dust, and other particulate 5 microns and larger. It is a particulate filter, not a coalescing filter -- it does not remove oil aerosols or submicron water mist. For applications requiring oil-free air, the C-FM14 must be followed by a coalescing filter. For basic particulate protection at a 1/4-inch connection, the C-FM14 on its own is adequate.
