SPEEDAIRE

SPEEDAIRE 4ZK87 Filter-Regulator 1/4 NPT 80 cfm 40 micron

SKU CH-6XZC-T6VZX

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

  • Delivers up to 80 cfm airflow for demanding pneumatic tools
  • 40 micron particulate filter removes contaminants to protect downstream equipment
  • 1/4 inch NPT female inlet fits standard shop air lines
  • Aluminum body with polycarbonate guarded bowl resists impact and corrosion
  • Manual drain and top-mounted reinforced nylon knob simplify routine maintenance

1/4 NPT Filter-Regulator for Compressed Air Systems

This SPEEDAIRE filter-regulator connects to a 1/4 inch NPT female inlet and delivers up to 80 cfm of filtered air. The 40 micron particulate element removes solid contaminants before they reach downstream tools. It suits workshops that need basic pressure regulation on a single supply line.

Installation Notes and Common Issues

The unit mounts in-line with left-to-right airflow and uses a top-mounted reinforced nylon knob for pressure adjustment. A manual drain requires periodic attention to prevent water carry-over. The polycarbonate bowl includes a guard but must be protected from solvents and high heat. No pressure gauge is included so one must be added separately.

Flow Capacity and Practical Limits

At 80 cfm maximum flow the regulator handles typical spray guns, sanders and small blast cabinets. The 150 psi pressure ceiling covers most shop compressors. Demand beyond the rated flow will cause pressure drop and reduced tool performance. Buyers needing higher flow or finer filtration should select a larger series.

Questions about this item

How do I confirm the SPEEDAIRE 4ZK87 is regulating pressure correctly after installation?

Check the downstream pressure with a separate gauge while adjusting the top-mounted knob; the unit handles up to 80 cfm at 150 psi maximum inlet pressure.

What comes with the SPEEDAIRE 4ZK87 and what must I supply?

The filter-regulator body, polycarbonate bowl with guard, 40 micron particulate element, and manual drain are included; you must add a pressure gauge and 1/4 NPT fittings.

When should I choose the 40 micron version of this filter-regulator?

Select the 40 micron model when you need general-purpose particulate removal for air tools and the 80 cfm flow rating matches your compressor output.
