GRACO 133546 – Air Filter / Regulator with Auto Drain, 3/4″ NPT, 140 PSI

GRACO 133546 – 3/4″ Filter, Air Regulator w/ Auto Drain, 140 PSI, 3/4″ NPT

The Air Filter-Regulator combination provides precision control over air pressure regardless of air demand rate and fluctuations in supply pressure. An air filter is used to separate dust, dirt, moisture and other contaminants from compressed air, resulting in optimal performance of pneumatic pumps.

Precise Pressure Control

Press-to-lock pressure control knob provides steady outlet flow at your desired set pressure

Moisture Removal

Prevent corrosive moisture from shortening the life of your pneumatic pump or air tools.

Flexible Mounting Options

Two gauge ports and optional wall mounting brackets allow for mounting in different orientations that best suit your application.

Air Filtration

Prevent harmful dirt, dust and other contaminants from entering your pneumatic pump or air tools with a built-in sintered bronze filter element.
