The Arrow Pneumatics N3548 High Flow FRL is a heavy-duty, three-stage air preparation assembly that filters, regulates, and lubricates compressed air in a single 1" NPT inline unit. Rated for 175 CFM, it is built for high-demand industrial air systems, large pneumatic tools, and main-line air conditioning where smaller modular FRLs can't keep up. Both the filter and lubricator use rugged 29 oz metal bowls with sight glasses, and an air gauge is included.
