Miller RTI Filter Kit for Spectrum 875

This new filter and bracket kit fits Miller Spectrum 875 and 875 Auto-Line plasma cutters. It mounts directly to the machine using a 1/4-inch NPT threaded connection. The kit is designed for plasma cutting workflows that require clean, dry compressed air.

RTI filter and bracket remove contaminants

The RTI filter element traps dirt, oil and water down to a 1-micron rating. By delivering cleaner air to the torch, it helps maintain consistent cut quality and extends consumable life. The included bracket secures the housing to the cutter chassis.

Suited for light to medium plasma cutting

The kit handles typical shop air supplies on compatible Spectrum models including 907390011, 907390012, 907396 and 907584 series units. It is not intended for high-volume industrial systems that demand larger filtration capacity or automated drain features.

Questions about this item

How often does the 1 micron RTI filter element need to be replaced on the Spectrum 875?

Replace the 1 micron RTI filter element when pressure drop across the filter indicates it is loaded with dirt, oil or water from the compressed air supply.

What is the first limitation during extended plasma cutting with this filter kit?

The 1 micron filter element becomes saturated with contaminants, reducing airflow to the plasma cutter and requiring element replacement.

Does the RTI filter and bracket assembly add noticeable heat or noise during all-day cutting?

The passive filter and bracket kit adds no heat or noise; it simply removes dirt, oil and water from the compressed air line.
