Description
The Dwyer Instruments AAFS Adjustable Air Flow Paddle Switch tool required for measuring the flow of air in different HVAC systems purposes such as air handlers, heating & cooling systems, and Variable Air Volume. This switch works using a stainless steel paddle which measures air velocity, the trip range being from 200 ft/min to 1800 ft/min. Transmission has an easy-to-use calibration mechanism which makes it operational in a variety of environments. The switch is especially useful to avoid the functioning of HVAC systems when the airflow is low, which is dangerous for the system. It has ABS housing and a galvanized steel base, making it long-lasting in harsh conditions.
