Rely on grainger for a wide range of duct pressure switch options. Flow switches for high temperature duct mounting high temperature duct mounted. An air switch senses positive negative or differential air pressure and actuates an internal switch. Peeco flow switches for high temperature duct mounting are specially designed for use at elevated duct temperatures.

Airflow switch spdt f62 series this control detects air flow or the absence of air flow in ducts responding only to the velocity of air movement. 3 6 out of 5 stars 9. Duct pressure switches automatically start and stop auxiliary devices like electronic air cleaners duct heaters humidifiers exhaust fans and duct booster fans. The flow switch should be mounted into a duct or chamber where the air paddle can freely point horizontally downwards.

We can achieve 400 f ratings with a simple micro switch upgrade. The standard flow switches are rated for 300 f. The switching point may be adjusted continuously within a wide range making the lps useful in a wide variety of applications. To avoid air swirl and paddle instability straight zones should be provided for a length of 5 times the diameter of duct upstream and downstream from the installation location.

The principle of operation is quite simple. Kobold lps air flow switches are widely used to control air flow setpoints in hvac duct applications. Free shipping by amazon. The series avfs adjustable air flow switch is specifically designed to monitor air flow in ducts and provides a 3 a contact output to indicate a change or loss of flow.
