NITRA® pneumatic AC series coalescing air filters allow finer removal of moisture, vapor and oil mist from compressed air applications. NITRA coalescing filters are available in a range of port sizes from 1/8" to 1/2" FNPT; replaceable 0.3-micron filter elements are standard, with an optional 0.01-micron filter element available for stricter filtration requirements. NITRA coalescing filters are available with semi-automatic / manual or full automatic drains, and polycarbonate or nylon bowls with metal guards are available on all sizes. All-metal bowls with sight gauge are available on larger sizes. The modular filter design enables easy field assembly for combining with NITRA pneumatic particulate filters and regulators (using optional modular assembly brackets). NITRA coalescing air filters start at $52.00 with a 2-year warranty.
