Keep air preparation equipment from starting up during maintenance.

A filter and regulator stacked together, these filter/regulators clean your compressed air and maintain the pressure. Connect them to other ARO units in the same series with joiner clamps to customize your air preparation system.

Replace the filter element in your ARO modular compressed air filter to trap solid particles and water droplets.

Swap out a damaged bowl on your ARO modular compressed air filter, or switch to a different bowl material or drain type.

Also known as coalescing filters, these filters remove compressor oil to extend the service life of air-powered tools and equipment.

Replace a damaged bowl on your ARO modular compressed air lubricator.

Prevent unauthorized or accidental pressure changes to these regulators—they let you lock down the set pressure.
