SPEEDAIRE 4ZK84 Filter-Regulator

The SPEEDAIRE 4ZK84 is a compact filter-regulator designed for compressed-air systems that require combined particulate filtration and pressure control in a single unit. It suits workshops and light industrial lines where space is limited and clean, regulated air is essential for pneumatic tools and equipment. The zinc body and metal bowl with sight gauge provide durability in daily use.

80 cfm flow with 40 micron filtration

Rated for a maximum flow of 80 cfm, the unit comfortably handles moderate-demand applications such as spray guns, impact wrenches and air-driven machinery. The 40 micron particulate element removes solid contaminants before they reach downstream components. At 250 psi maximum operating pressure the regulator maintains consistent outlet pressure, though flow will drop off if system demand exceeds the rated capacity.

3/8 NPT inlet with left-to-right flow

The 3/8 inch NPT female inlet connects directly to standard compressor piping without adapters. Air travels left to right through the body, and the top-mounted reinforced nylon knob allows easy pressure adjustment. A manual drain on the metal bowl lets operators remove collected moisture and debris. No pressure gauge is included, so a separate gauge or panel-mounted unit must be supplied by the installer.

Questions about this item

Will the 3/8 NPT female inlet thread match my existing 3/8 NPT male compressor hose?

Yes, the filter-regulator has a 3/8 inch NPT female air inlet that connects directly to a 3/8 NPT male hose fitting.

How can I confirm the 40 micron particulate filter is trapping debris after installation?

The metal bowl includes a sight gauge so you can visually inspect collected particles and condensate without removing the bowl.

Does the box contain a pressure gauge or must I buy one separately?

No pressure gauge is included; the body has a gauge port for a separate gauge you supply.
