SPEEDAIRE 4ZM01 Filter/Regulator Lubricator 5-150 psi

SKU CH-FEFY-V21QM

Combines 5-micron filtration, pressure regulation and lubrication for compressed-air lines up to 150 psi with a 275 cfm flow capacity

  • 5 micron filter removes fine particles for cleaner air supply
  • 275 cfm maximum flow supports high-demand pneumatic tools
  • 150 psi regulation range provides precise pressure control for varied applications
  • 32 oz metal bowls with sight glass allow easy fluid level monitoring
  • Manual drain enables quick moisture removal without power loss

Heavy-Duty Air Preparation Unit

The SPEEDAIRE 4ZM01 combines a filter, regulator and lubricator in one assembly for compressed-air systems that need clean, regulated and lubricated supply. It suits industrial maintenance shops and automotive workshops running tools or equipment from a central compressor line.

275 cfm Flow with 5-Micron Filtration

The unit delivers a maximum flow of 275 cfm through a 1-inch NPT female inlet, feeding both bowls with 32 oz capacity each. The 5-micron element removes particulates before regulation, while the manual drain clears collected moisture. Pressure adjusts from 5 to 150 psi via a top-mounted reinforced-nylon knob; the housing is rated to 250 psi maximum operating pressure.

Metal Bowls with Sight Glass for Visual Checks

Both filter and lubricator bowls are metal with integrated sight glasses, allowing operators to confirm fluid levels and contamination at a glance. Air travels left to right across the 14 3/4-inch wide body, keeping piping layout straightforward. The manual drain requires periodic attention but avoids the complexity and failure points of automatic drains in dirty environments.

Questions about this item

Will the 1 in NPT inlet connect to the 1 in NPT outlet on my existing compressor tank?

Yes, the unit has a 1 in female NPT inlet that matches a standard 1 in male NPT tank outlet; use thread sealant on the male threads when joining them.

How do I verify the 5 micron filter and lubricator are working after installation?

Check the metal sight glasses on both 32 oz bowls — clear fluid in the filter bowl means no water carry-over, and a steady drip in the lubricator sight dome confirms oil delivery.

Does the package include the 1 in NPT fittings and airline oil, or must I buy them separately?

The unit ships assembled with the filter, regulator, and lubricator bowls installed; 1 in NPT pipe fittings and pneumatic tool oil are not included and must be purchased separately.
