FlowGuard is a sensor to check and indicate the airflow in your extraction arm
The FlowGuard is an under-pressure sensor for mounting on an extraction arm or any other device to check whether the airflow is adequate. This is achieved by measuring the pressure difference inside and outside the extraction arm.
- Applications where indication of present airflow in solid tube extraction arms is desirable.
- Easy installation
- No electrical wiring
- Configurable to arm diameter
Health and safety regulations such as the British Health and Safety Executive HSG 258 guideline and European EN ISO 21904 standard controlling airborne contaminants at work require, among other things, that users of welding fume extraction systems have the right to know if they are using proper extraction equipment.
Properly used extraction arms prevent welding fumes to reach the welder’s breathing zone. FlowGuard confirms proper airflow by simple green LED.
