The Miller 287178 is a high-performance replacement battery engineered specifically for the Miller Generation 2 Powered Air Purifying Respirator (PAPR) blower unit. This component is critical for maintaining the operational integrity and safety compliance of the PAPR system in industrial environments. The unit utilizes advanced Lithium-Ion (Li-Ion) chemistry, which provides a superior energy-to-weight ratio compared to traditional Nickel-Cadmium or Nickel-Metal Hydride alternatives. With a nominal voltage of 14.8V and a capacity rating of 3.0A, this battery is designed to deliver consistent power output to the blower motor, ensuring constant airflow rates are maintained throughout the discharge cycle.
One of the primary technical benefits of this specific Li-Ion configuration is the absence of 'memory effect.' This allows maintenance personnel and operators to recharge the battery at any state of discharge without degrading the battery's maximum capacity over time. The charging profile is efficient, requiring approximately 3 hours to reach full capacity using the compatible Miller charger (sold separately). A fully charged unit provides up to 8 hours of runtime, depending on filter loading and airflow settings, effectively covering a standard industrial shift.
The physical form factor is integrated seamlessly into the Gen 2 blower housing, maintaining the IP rating and ergonomic balance of the respirator assembly. It is essential to note that this SKU (287178) is not backward compatible with Generation 1 systems. Proper inventory management requires verifying the blower generation before procurement. The battery casing is constructed to withstand the rigors of welding environments, offering resistance to impact and thermal fluctuations common in heavy fabrication settings.
