Prices & Options
The Helios SWT is a mechanical airflow switch designed to monitor air velocity in ventilation ducts and piping systems, especially in combination with electric heaters. Featuring a durable stainless steel paddle, the unit detects airflow levels and triggers switching actions based on preset velocity thresholds.
The SWT can be configured as either a normally open or normally closed switch and is designed to activate when air speeds reach minimum or maximum thresholds — typically at approximately 1.5 m/s and 3.0 m/s respectively. Its robust construction includes mounting hardware for secure installation on the exterior of duct systems, ensuring reliable performance in HVAC applications where consistent airflow monitoring is essential for safety and system control.
