SPEEDAIRE 4ZK89 Filter-Regulator 3/8 NPT 120 cfm 40 micron
Combines a 40 micron particulate filter with a regulator for 120 cfm flow at 150 psi through a 3/8 NPT inlet
- Delivers up to 120 cfm airflow for demanding pneumatic tools
- 40 micron filter traps fine particles to protect downstream equipment
- Aluminium body withstands 150 psi maximum operating pressure
- Polycarbonate bowl with guard resists impact and chemical exposure
- Top-mounted reinforced nylon knob allows quick pressure adjustment
SPEEDAIRE 4ZK89 Filter-Regulator
The SPEEDAIRE 4ZK89 is a combination filter and regulator designed for compressed air systems. It features a 3/8 inch NPT air inlet and a maximum flow rate of 120 cfm. The unit uses a particulate filter rated at 40 micron and has a maximum operating pressure of 150 psi. Its body is constructed from aluminum with a polycarbonate filter bowl and guard.
Suited for intermediate duty air preparation
This filter-regulator suits workshops needing combined filtration and pressure control in a single intermediate duty unit. The left-to-right flow direction and top-mounted adjustment knob allow straightforward installation and setting. Buyers requiring an integrated pressure gauge should look elsewhere as none is included. Those needing automatic drain functionality or a different port size will also need an alternative solution.
120 cfm capacity with 40 micron filtration
The 120 cfm maximum flow rate comfortably handles air supply for multiple pneumatic tools or equipment runs. The 40 micron particulate filter captures coarse contaminants to protect downstream components. Headroom exists within the 150 psi maximum operating pressure for typical shop systems. The manual drain requires periodic operator attention to remove accumulated moisture and debris from the bowl.

Questions about this item
What size NPT fitting do I need on my compressed-air line to connect the 3/8 in NPT inlet on this filter-regulator?
The unit has a 3/8 in NPT air inlet, so your supply hose or pipe must terminate in a matching 3/8 in NPT male thread to seal properly.
Will the 120 cfm maximum flow and 150 psi pressure rating handle the same tools I run on my older 1/4 in NPT regulator?
This filter-regulator delivers up to 120 cfm at 150 psi, which is higher than most 1/4 in NPT units; you can keep your existing tools, but ensure downstream fittings and hoses are rated for the increased flow and pressure.
How can I verify the 40 micron particulate filter is working after I install the unit?
Open the manual drain periodically; if water and visible debris exit the polycarbonate bowl with guard, the 40 micron element is trapping contaminants as designed.
