SPEEDAIRE 4ZK96 filter regulator 140 cfm 250 psi 11.93 in H 3.15 in W
Filters air to 40 micron and regulates pressure up to 250 psi with a 140 cfm flow rate
- 140 cfm maximum flow rate for high-demand air tools
- 250 psi maximum operating pressure handles heavy-duty applications
- 40 micron particulate filter removes contaminants from air lines
- Metal bowl with sight gauge allows visual monitoring of drainage
- Aluminum body construction provides durability in workshop environments
Filter regulator for compressed-air systems
The SPEEDAIRE 4ZK96 filter regulator combines particulate filtration and pressure control in a single aluminium body. It accepts a 1/2 in NPT female inlet and delivers up to 140 cfm at a maximum operating pressure of 250 psi. The unit is suited for workshops and industrial lines that need clean, regulated air without a separate filter and regulator.
Metal bowl with sight gauge and manual drain
A 40 micron particulate element traps contaminants while the metal bowl lets operators see the fluid level at a glance. Condensate is removed through a manual drain, avoiding automatic mechanisms that can jam. The reinforced nylon adjustment knob on top sets downstream pressure smoothly across the full 250 psi range.
Left-to-right flow with no gauge supplied
Air moves from left to right through the 3.15 in wide body, simplifying pipe layout in tight spaces. No pressure gauge is included, so users must add one matching their readout preference. The standard-duty series fits existing 1/2 in NPT plumbing without adapters.

Questions about this item
How do I install the 1/2 in NPT inlet and which step is often missed?
Connect the 1/2 in NPT female inlet with thread sealant, orient the body so air flows left to right, then tighten securely; the step most often missed is verifying the flow-direction arrow before final tightening.
What maintenance will the 40 micron particulate filter and metal bowl with sight gauge need later?
Periodically open the manual drain to remove collected moisture and debris; inspect the sight gauge for contamination and replace the 40 micron filter element when pressure drop becomes noticeable or the element appears dirty.
At what point does the 250 psi maximum operating pressure limit performance during sustained use?
The regulator is rated for 250 psi maximum operating pressure; sustained inlet pressure above this limit will cause the internal relief to vent or the diaphragm to lose control, so keep supply pressure at or below 250 psi.
