Air flow switch - AVFS series

Adjustable air - flow switch from AVFS can replace instruments that are from Dwyer. This is a kind of switch that is designed specifically for monitoring the ducts that are meant for air flow and also can provide output of 3A for indicating loss or change in flow. The device can be used for showing normal status, one needs to turn on the fan or the unit of air handling. AVFS can be activated by altering damper or by decreasing the speed of the fan. This device can indicate when there is loss in flow. There are various colors of LED indicators available for showing different status.

Adjustable piston flow switch / in-line - PFT series

An AFS flow switch is adjustable externally and is perfect for the purpose of protecting the machine tools from the failure of coolant flow, and also to shield bearings from the loss of lubricant. It is also capable of ensuring proper air flow. It can be used to set pressure flow settings of the pressure up to 1000 psig, keeping pressure drop low and ensuring absolute reliable and repeatable flow. The device is placed inside the covering that is made out of stainless steel or brass and so it can be used with oils, gases, compatible liquids and also water without any kind of issues. The product is highly versatile and reliable for various applications without any issues of wear.
