  • Delivers clean, regulated air with integrated lubrication
  • 5-micron filter removes fine contaminants from the supply
  • 10 cfm maximum flow supports a range of pneumatic tools
  • Adjustable 5 to 125 psi output via reinforced nylon knob
  • Heavy-duty polycarbonate bowls with 1 oz capacity each

SPEEDAIRE 4ZM04 Filter Regulator Lubricator

The SPEEDAIRE 4ZM04 combines filtration, pressure regulation and lubrication in a single unit for compressed-air systems. It is suited for workshops and light industrial lines that need clean, regulated and lubricated air from one compact assembly. The 1/4 in NPT female ports accept standard fittings for quick installation. Operators who want an all-in-one air preparation module will find it matches that requirement.

5 to 125 psi regulated range and 10 cfm flow limit

The regulator adjusts outlet pressure between 5 and 125 psi using a top-mounted reinforced-nylon knob. Maximum flow is rated at 10 cfm, so the unit supports tools and circuits that stay within that volume. The 5 micron polycarbonate filter bowl holds 1 oz of condensate and uses a manual drain. Systems demanding higher flow or finer filtration will exceed the practical limits of this device.

150 psi maximum operating pressure

The housing is rated for 150 psi maximum operating pressure, which sets the absolute ceiling for inlet supply. Any compressor or line pressure above that value risks damage and voids the intended safety margin. Buyers must verify that their source pressure never surpasses 150 psi before installing this filter regulator lubricator.

Questions about this item

Which SPEEDAIRE 4ZM04 version should I choose for my air line?

The 4ZM04 is a single combined filter-regulator-lubricator unit with a 1/4 in NPT inlet, 5 micron filter, 1 oz polycarbonate bowls and manual drain; no alternate capacities or versions are offered for this model.

What does the 125 psi rating mean when the unit is installed?

The regulator adjusts outlet pressure from 5 to 125 psi, while the housing is rated to 150 psi maximum operating pressure, so the 125 psi figure is the usable upper limit for downstream tools.

What does the 1/4 in NPT interface cap in practice?

The 1/4 in NPT female ports limit the maximum flow to 10 cfm, so the unit suits smaller air tools and branch lines rather than high-volume shop mains.
