Fume cupboard regulator FHR 310
FHR 310 is a regulator unit for airflow control of fume cupboards. Together with an air velocity sensor, a control damper and an indicator, the air velocity in the working opening of the fume cupboard can be regulated and kept constant.
Gap height sensor FHL 95
FHL 95 can be connected as an accessory to the FHR 310 fume cupboard regulator. When FHL 95 is used, the air consumption of the fume cupboard becomes available and is controlled automatically. In addition, FHL 95 gives significantly faster regulation when the sash is moved.
Air velocity sensor HPS 50
HPS 50 is mounted on the fume cupboard so that the sensor senses the static negative pressure between the inside of the cupboard and its surroundings. The sensor measures the air velocity through the measuring tube that goes into the fume cupboard.
Indicator FHI 350
FHI 350 is an indicator for connection to the FHR 310 fume cupboard regulator.
Presence detector IR 50
IR 50 is mounted above the fume cupboard to indicate the movement of people within the working area of the fume cupboard. With IR 50 connected to the FHR 310 fume cupboard regulator, the “Economy” operating mode can be used.
IR 50 switches to the “Normal” operating mode immediately when someone enters the working area of the fume cupboard. Economy mode is activated automatically after a set time delay when work stops.
