AP-BLW-02 - Walter ArcOne AirPlus Replacement Blower Unit with HE Filter

Technical Overview of the Walter AirPlus Blower Assembly

The Walter AP-BLW-02 AirPlus Blower with HE Filter is the core component of the AirPlus Powered Air Purifying Respirator (PAPR) system. Engineered for industrial environments where particulate contaminants pose a significant health risk, this blower unit is designed to deliver a consistent supply of clean, filtered air to the welder's breathing zone. The unit operates on a positive pressure principle, ensuring that any leakage in the headtop seal forces air outward, thereby preventing the ingress of contaminated ambient air.

At the heart of the AP-BLW-02 is a high-performance motor coupled with a High Efficiency (HE) particulate filter. This filtration system is rated to capture 99.97% of airborne particles down to 0.3 micrometers in size, effectively mitigating exposure to hazardous welding fumes, including hexavalent chromium, manganese, and other metal oxides. The blower automatically compensates for filter loading to maintain the required airflow, ensuring compliance with respiratory safety standards throughout the filter's lifespan.

Safety and reliability are paramount in the design of the AirPlus blower. It features a comprehensive alarm system that utilizes audible, visual, and vibrating indicators to alert the user to low battery levels or restricted airflow (e.g., a clogged filter or blocked hose). This redundancy is critical in high-noise industrial settings where an audible alarm alone might be missed. The unit is constructed from impact-resistant materials capable of withstanding the rigors of daily shop use, including exposure to sparks and spatter. It is designed to integrate seamlessly with the Walter / ArcOne AirPlus battery and belt systems, providing a modular solution for respiratory protection.

The AP-BLW-02 is an essential replacement or upgrade component for existing AirPlus systems, ensuring that facility safety managers can maintain their fleet of PAPR units with OEM-quality parts. Its efficient design optimizes battery usage, allowing for extended operation times suitable for full work shifts.
