SPEEDAIRE 4ZK92 Filter-Regulator 1/4 NPT 80 cfm 40 micron

SKU CH-SDKH-ASRJ3

Combines 40-micron particulate filtration with pressure regulation at up to 80 cfm through a 1/4 NPT inlet

  • Delivers 80 cfm airflow for high-demand pneumatic tools
  • 40 micron particulate filtration protects downstream equipment
  • 1/4 in NPT inlet fits standard compressed-air piping
  • 150 psi maximum pressure handles heavy-duty shop systems
  • Manual drain and included gauge simplify daily maintenance

Filter-Regulator 1/4 NPT 80 cfm

The SPEEDAIRE 4ZK92 combines a particulate filter and pressure regulator in a single intermediate-duty unit. It suits workshops and light industrial lines that need clean, regulated air at flows up to 80 cfm.

Installation and common issues

The body has a 1/4 in NPT inlet and flows air left to right, so pipework must match that orientation. A polycarbonate bowl with guard requires hand-tightening only; over-torquing cracks the bowl and leaks appear at the manual drain.

Pre-order checks

Verify your supply pressure does not exceed 150 psi and that downstream tools operate within the regulated range. Confirm 1/4 in NPT thread compatibility and that a 40 micron filtration level meets your equipment requirements.
