Frequently Asked Questions

What is the SPEEDAIRE 4ZK81 filter-regulator used for?

The SPEEDAIRE 4ZK81 miniature filter-regulator is used in compressed air systems to remove particulates down to 0.01 micron and regulate pressure from 5 psi to 150 psi. It is ideal for pneumatic tools, control panels, and light industrial applications requiring clean, regulated air at low flow rates up to 4 cfm.

What are the specifications of the SPEEDAIRE 4ZK81?

The SPEEDAIRE 4ZK81 has a 1/4 in NPT port size, 4 cfm flow capacity, 0.01 micron filtration, and a pressure range of 5 psi to 150 psi. It features a zinc body with rubber seals, is gauge-ready (gauge not included), and is part of the Speedaire Miniature Series. The manufacturer part number is 4ZK81.
