Air Handling System Airflow Switch Waterproof Brass Level
Description
The flow switch is to instruct the switch of the system according
to the flow. Set the upper limit for the flow switch or
When the flow reaches the limit, the flow switch will send out a
signal or an alarm, and the system will run or stop. Generally,
systems that require flow will use flow switches. Depending on the
system, as well as the flow switch model and other factors, the
place of use is also different, which should be determined
according to the specific situation.
KAFS adjustable Airflow Switches are used to control and monitor
the flow of air and non-corrosive gases in ducts, ideal for ducts,
air conditioning and air handling systems
Application
Control and monitor air and non aggressive gases flow in ducts,
chambers, etc.,of heating, cooling, and air conditioning equipment.

Installation
The flow switch should be mounted into a duct or chamber where the
air paddle can freely point horizontally downwards. 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.
Note:
The units are factory calibrated to the minimum switch-off value.
To increase the set value, adjust the range screw clockwise. Due to
the risk of fracture at air speeds of higher than 5.0 m/sec, the
paddle must be cut off on the marked side. When the paddle is cut
off, the minimum cut-out value increases from 1.0 m/sec to 2.5
m/sec.
