SPEEDAIRE 4ZM02 Filter Regulator Lubricator 150 psi 160 cfm 32 oz bowls

SKU CH-8ZGK-GMCW3

Combines filtration, regulation and lubrication in a single unit rated for 150 psi and 160 cfm with 32 oz metal bowls

  • Delivers up to 160 cfm airflow for high-demand pneumatic tools
  • Maintains precise pressure control from 5 to 150 psi
  • 5-micron filtration with metal bowls and sight glass protects equipment
  • 32 oz bowl capacity on both filter and lubricator reduces maintenance stops
  • Heavy-duty series construction with reinforced nylon knob for durability

SPEEDAIRE 4ZM02 Filter Regulator Lubricator

The SPEEDAIRE 4ZM02 combines a filter, regulator and lubricator in a single heavy-duty unit. It accepts a 3/4 inch NPT female air inlet and delivers a maximum flow of 160 cfm. The filter element is rated at 5 micron and uses a metal bowl with a sight glass. Both the filter and lubricator bowls hold 32 oz of fluid.

Suited for workshops needing clean.

This unit fits systems that require left-to-right airflow with a top-mounted knob adjustment. The reinforced nylon adjustment mechanism and manual drain suit routine maintenance schedules. Operations needing automatic draining or a different flow direction should consider other configurations.

Maximum operating pressure of 250 psi

The regulator adjusts output pressure from 5 to 150 psi while the housing withstands up to 250 psi. This pressure envelope determines whether the assembly matches the downstream tool requirements. Verify the system pressure before installation.

Questions about this item

What size NPT air inlet does the 4ZM02 need on my compressor line?

The unit has a 3/4 in female NPT air inlet, so your supply line must match that thread size and gender for a direct connection.

Will the 160 cfm maximum flow rate restrict my older 1/2 in distribution piping?

The 4ZM02 is rated for 160 cfm at 150 psi; 1/2 in pipe will add pressure drop at that volume, so expect lower downstream pressure unless you upsize the piping.

How do I verify the filter and lubricator are working after installation?

Check the metal sight glasses on both 32 oz bowls — condensate should collect in the filter bowl and oil should drip steadily in the lubricator bowl when air flows.
