Speedaire 4ZK75 Air Pressure Regulator Assembly

Speedaire 4ZK75 Air Pressure Regulator Assembly is a compact 1/4 in NPT filter-regulator in the Miniature Series that combines a 5 micron particulate filter with a regulator in a single inline unit. The top-mounted adjustment knob makes setting downstream pressure straightforward, with an adjustable output from 5 to 125 psi and a maximum operating pressure of 150 psi. The unit provides up to 14 CFM airflow and uses a polycarbonate filter bowl for easy visual inspection, with a manual drain for maintenance. The zinc-bodied housing measures about 1 5/8 in wide, and both inlet and outlet ports are 1/4 in NPT. This Speedaire assembly is well suited for bench-top pneumatic tools and compact automation systems where clean, regulated air is required, delivering filtered air and precise pressure in one space-saving package.
