Miller 264573 PAPR Welding Respirator

The Miller 264573 PAPR T94-R is a powered air-purifying respirator system built for professional welders. It combines a T94i-R helmet assembly with a belt-mounted blower unit to deliver filtered air during welding and grinding tasks. The package includes a tool bag for transport and storage.

HEPA filtration with dual batteries

The system uses a HEPA filter protected by six prefilters and a spark guard to capture particulates. Two included lithium-ion batteries power the blower assembly, while a flow meter lets the operator confirm adequate airflow. A padded belt and shoulder straps distribute the weight for extended wear.

Sustained airflow for long shifts

Under continuous operation the blower maintains a steady supply of filtered air through the breathing tube and cover. The dual-battery setup allows one pack to charge while the other runs, supporting full-shift coverage without interruption. Prefilters extend the life of the primary HEPA element in heavy-particulate environments.

Questions about this item

How do I attach the breathing tube to the blower assembly and helmet, and what step is often missed?

Connect the breathing tube to the blower outlet and the helmet inlet, then secure the tube cover; the step often missed is checking airflow with the flow meter before welding.

Which components will need replacement over time and how often?

Prefilters and the HEPA filter require periodic replacement; prefilters are changed when airflow drops, while the HEPA filter is swapped after extended use or when the flow meter indicates low flow.

What limits continuous operation during a long shift?

Battery runtime limits sustained use; the two included lithium-ion batteries power the blower assembly, and swapping to a charged battery is needed when the current pack depletes.
