AP-AFI-01 - Walter Airplus PAPR Flow Test Tube

Essential Maintenance for Respiratory Safety

The Walter Airplus Air Flow Indicator (AP-AFI-01) is a critical component in the maintenance and daily operation of the Walter Airplus Powered Air Purifying Respirator (PAPR) system. Designed to provide a clear and immediate visual confirmation of airflow performance, this device ensures that the blower unit is delivering the required volume of clean air to the welder's headtop. In industrial environments where hazardous fumes and particulates are present, verifying the functionality of respiratory equipment is not just a recommendation—it is a safety necessity.

Constructed from durable, impact-resistant materials, the Air Flow Indicator is built to withstand the rigors of the shop floor. It functions by measuring the velocity of the air being pushed through the breathing tube. Before every shift, or whenever the PAPR system is reassembled, the user simply attaches the indicator to the air outlet. If the internal float rises above the designated mark, the system is generating sufficient pressure to protect the user. If it fails to reach the mark, it signals that the battery may need charging or the filters require replacement.

For facility managers and safety officers, ensuring that every Airplus unit is equipped with a functioning Air Flow Indicator is a key part of compliance with occupational health and safety regulations. Regular testing with the AP-AFI-01 prevents the inadvertent use of compromised equipment, thereby safeguarding the long-term health of the workforce. This simple yet effective tool is an indispensable part of the Walter Surface Technologies safety ecosystem.
