287175 - Miller Gen 2 PAPR Blower Filter Housing Cover

Genuine Miller Replacement for PAPR Systems

The Miller 287175 Filter Cover is a critical component designed exclusively for the Miller PAPR (Powered Air Purifying Respirator) Gen 2 systems. As a genuine Miller Electric replacement part, this cover ensures the structural integrity and proper functionality of your respiratory protection equipment. In industrial environments where air quality is a primary concern, maintaining the seal and security of your filtration system is paramount. This specific cover is engineered to fit the blower unit of the Gen 2 PAPR, providing a secure housing for the essential filtration media.

Functionally, the 287175 cover serves a dual purpose. First, it acts as the mechanical retainer for both the pre-filter and the main HEPA filter. Without this cover properly installed, the filters cannot maintain the necessary seal against the blower unit, potentially allowing contaminated air to bypass the filtration stage. Second, it provides a rugged physical barrier that protects the delicate filter media from external impact, sparks, spatter, and debris common in welding and fabrication shops. The cover is constructed from durable materials capable of withstanding the rigors of daily industrial use.

It is important to note that this part number (287175) refers strictly to the plastic cover assembly. It does not include the spark guard, pre-filter, or HEPA filter, which must be purchased separately or retained from your existing setup if they are still in serviceable condition. This component is specifically compatible with the Miller Face Shield PAPR (Gen. 2) and is not interchangeable with previous generations or other brands of PAPR systems. Ensuring you have the correct generation of parts is vital for compliance with safety standards and for the effective operation of the blower unit.

For procurement managers and safety officers, stocking replacement covers like the Miller 287175 is a proactive measure to minimize downtime. A cracked or broken filter cover can render a PAPR unit unusable until replaced, halting production for the affected welder. By using genuine Miller parts, you guarantee a perfect fit and adherence to the manufacturer's original specifications for airflow and protection factors. This part is easily installed without tools, allowing for rapid maintenance turnarounds in busy shop environments.
