Tired of Insensitive Vinyl Tube Air Switches? Upgrade to the Electronic Probe
Updated: 1 day ago
If you own a whole house scent machine connected to your central AC, you might have faced a messy, expensive headache: your HVAC system stopped but the diffuser kept pumping. When the airflow ceases, the waterless cold air diffuser continues to spray, causing premium essential oils to condense inside the dark ductwork. This results in costly oil leaks in your vents and sticky oil paste residue on your walls.

To solve this, many turn to traditional vinyl tube air pressure switches. However, these mechanical switches are notoriously insensitive, requiring high duct pressure to trigger and frequently failing in modern, low-airflow systems.
It is time to upgrade. Meet the Kevinleo HVAC Airflow Sensing Switch—the ultimate smart oil saver designed to eliminate fragrance waste and protect your home HVAC system.
The Tech Solution: 0.3m/s Electronic Wind Speed Sensing
Unlike traditional models, the Kevinleo electronic airflow switch features an advanced electronic metal probe. Instead of relying on crude air pressure, it tracks airflow velocity with 100% reliability and zero lag.
The Kevinleo electronic probe detects micro-airflow down to 0.3m/s, serving as a reliable alternative to traditional duct sensors.
