Description
Nortec Humidity Air Proving Switch — Duct Mounted (SKU 2598427)
The Nortec Humidity 2598427 is a single-pole, duct-mounted air proving switch designed to verify the presence of adequate airflow before allowing a humidifier system to operate. By confirming that air is actively moving through the duct, this switch provides a critical safety interlock that helps prevent moisture damage, bacterial growth, and equipment failure caused by humidifier operation in a static or low-airflow condition.
Key Features
- Single-pole switching action for reliable airflow verification
- Duct-mounted design for straightforward installation in supply or return air ducts
- Acts as a safety interlock to prevent humidifier activation without confirmed airflow
- Compatible with Nortec Humidity humidification systems requiring air proving protection
- Durable construction suited for commercial and light-industrial HVAC applications
- Helps protect ductwork, coils, and building interiors from unintended moisture exposure
Application
This air proving switch is an essential component in humidifier control circuits. When installed in the duct, it senses differential air pressure created by the blower or air handler. Once sufficient airflow is detected, the switch closes its circuit, signaling the humidifier control board that it is safe to produce steam or moisture. If airflow drops below the threshold — such as during a blower failure or filter blockage — the switch opens, shutting down the humidifier and preventing potential water damage or microbial hazards.
