DeWalt® 18V / 20V MAX / FLEXVOLT → Miller® PAPR2 / Vortex HDV Battery Adapter (Premium Series)

Power your compatible Miller PAPR2 or Vortex HDV from DeWalt 18V XR, 20V MAX or FLEXVOLT batteries. Regulated. Battery Protected. Serviceable. Worksite Ready.

A purpose-built DeWalt battery adapter for the Miller PAPR2 / PAPR II and Vortex HDV.

The PlasticBurners Premium DeWalt to Miller PAPR2 / Vortex HDV Battery Adapter allows compatible Miller powered air purifying respirator blower units to operate from compatible DeWalt 18V XR, 20V MAX and FLEXVOLT slide batteries.

It is designed as an aftermarket alternative power source for systems using Miller PAPR II battery part number 287178, including compatible Miller Vortex HDV PAPR systems using the 287172 blower assembly.

Instead of relying solely on the dedicated Miller 287178 battery, users already invested in the DeWalt battery platform can power their compatible PAPR from batteries they may already use across their tools.

Inside is a high-efficiency regulated power system with built-in DeWalt battery protection, engineered to provide stable operating power to the PAPR while automatically protecting the connected battery from excessive discharge.

The Premium Series also features conformal-coated electronics, a tough ABS housing and long-term factory serviceability so suitable adapters can be repaired, refreshed or repowered rather than simply discarded.

✔ Run Your Miller PAPR2 / Vortex HDV From DeWalt Batteries

Compatible with DeWalt 18V XR, 20V MAX and FLEXVOLT battery platforms — use batteries and chargers you may already own instead of managing another dedicated battery ecosystem.

This PlasticBurners adapter is designed for compatible Miller PAPR systems that normally use:

• Miller PAPR II / PAPR2 battery: 287178
• Miller Vortex HDV battery: 287178
• Compatible blower assembly: 287172

Instead of installing Miller battery 287178, the PlasticBurners adapter allows a compatible DeWalt 18V XR, 20V MAX or FLEXVOLT battery to provide power to the PAPR blower through an internally regulated power system with built-in battery protection.

Searching for a Miller 287178 battery alternative? This product is specifically designed as an aftermarket DeWalt battery adapter for compatible Miller PAPR2 / PAPR II and Vortex HDV systems using battery part number 287178.

✔ Purpose-Built for Miller PAPR2 / Vortex HDV

This isn't simply a battery holder with wires attached. The adapter is purpose-built to interface compatible DeWalt battery platforms with compatible Miller PAPR2 and Vortex HDV blower systems. Proper power conversion, proper battery protection and a purpose-designed PAPR connection.

✔ DeWalt 18V / 20V MAX / FLEXVOLT Compatible

Designed to accept compatible DeWalt slide batteries across the 18V XR, 20V MAX and FLEXVOLT platforms, giving users greater flexibility in battery capacity and availability.

✔ Factory Repairable, Refreshable & Repowerable

The Premium adapter is designed as serviceable equipment rather than sealed throwaway electronics. Internal components are designed to be replaceable, allowing suitable units to be factory repaired, refreshed or fully repowered where practical.

✔ High-Efficiency Regulated Power

DeWalt battery voltage changes as the battery discharges. The PlasticBurners Premium adapter regulates that changing battery voltage to provide stable operating power for the compatible Miller PAPR system. Stable regulated output throughout the usable battery range.

✔ Built-In DeWalt Battery Protection

The Premium adapter includes automatic low-voltage protection designed to shut the PAPR down when the DeWalt battery reaches the adapter's low-voltage threshold. Automatic low-voltage cutoff helps protect the battery from excessive discharge — no manual battery voltage monitoring required.

✔ Conformal-Coated Mainboard

The main electronics are conformal coated to provide additional protection against dust, moisture and harsh workshop conditions. Built for fabrication shops, workshops and real worksites.

✔ Tough ABS Housing

Designed and manufactured in-house by PlasticBurners using a tough ABS housing. Strong, compact, serviceable and designed for everyday worksite use.

The adapter replaces the battery power source only. It does not modify the PAPR blower's airflow control, filter system, alarm system, helmet or respiratory components.

Operating time will vary depending on battery capacity and condition, battery age, temperature, blower operating mode, filter restriction and operating conditions.

DeWalt battery, DeWalt charger, PAPR blower, helmet, filters and other accessories are not included.

What battery does the Miller PAPR2 use?

The Miller PAPR II / PAPR2 Gen 2 blower uses Miller battery part number 287178. The PlasticBurners Premium DeWalt adapter is designed as an aftermarket alternative power source for compatible systems using the 287178 battery.

What battery does the Miller Vortex HDV PAPR use?

Compatible Miller Vortex HDV systems use Miller PAPR battery 287178 with the 287172 blower assembly. This PlasticBurners adapter allows compatible Vortex HDV systems to be powered from supported DeWalt batteries instead.

Is there a DeWalt adapter for the Miller PAPR2?

Yes. The PlasticBurners Premium DeWalt → Miller PAPR2 / Vortex HDV Battery Adapter is specifically designed to power compatible Miller PAPR2 systems from compatible DeWalt 18V XR, 20V MAX and FLEXVOLT batteries.

Can I replace Miller battery 287178 with a DeWalt battery?

A DeWalt battery cannot connect directly to the Miller blower. The PlasticBurners adapter provides the physical interface, regulated power conversion and low-voltage battery protection required to use a compatible DeWalt battery as an aftermarket power source for supported PAPR2 / Vortex HDV systems.

Does it work with DeWalt FLEXVOLT batteries?

Yes. Compatible DeWalt FLEXVOLT batteries can be used with the adapter alongside supported DeWalt 18V XR and 20V MAX slide batteries.

Are DeWalt 18V and 20V MAX batteries compatible?

DeWalt markets this battery platform as 18V XR in Australia and many international markets, while equivalent platform batteries are commonly marketed as 20V MAX in North America. This adapter is designed to support compatible slide-battery versions of these platforms.

Does the adapter regulate the DeWalt battery voltage?

Yes. DeWalt battery voltage varies during discharge, so the PlasticBurners Premium adapter uses an internal high-efficiency regulated power system to provide stable operating power to the compatible Miller PAPR blower.

Does the adapter protect the DeWalt battery from over-discharge?

Yes. The Premium adapter includes built-in DeWalt battery protection with automatic low-voltage cutoff. When the battery reaches the adapter's low-voltage threshold, power to the PAPR is automatically shut down to help prevent excessive battery discharge.

Can I charge the DeWalt battery normally?

Yes. Remove the DeWalt battery from the adapter and charge it using the appropriate DeWalt charger as you normally would.

Is the PlasticBurners Miller PAPR adapter repairable?

Yes. PlasticBurners Premium adapters are designed with long-term serviceability in mind. Suitable units can be inspected and, where practical, factory repaired, refreshed or repowered using replacement electronics and internal components.

Who makes the DeWalt to Miller PAPR2 adapter?

The adapter is designed and manufactured by PlasticBurners. PlasticBurners develops aftermarket battery adapter and power conversion products for professional equipment, including powered air respirator systems.
