Fume Cupboards & Alarms
Axair’s Labair controls range has been created for applications involving hazardous fume extraction such as fume cupboards and chemical cabinets. There are two models available A and C, both of which are available in a standard version or Digital.
Both the A and C series are white with 3 push buttons: fan on/off, light on/off and alarm mute. They also feature a green LED light that illuminates to signify that the airflow is OK, a red LED light that flashes to alert that the air speed is too low and a sash high LED which starts flashing when the sash position has been tripped. Both controls feature a calibration LED which turns off once calibration is complete. Labair controllers are factory pre-calibrated at 0.5 m/s but re-calibration is possible, and both feature a high precision numerical airflow sensor, alarm relay with an optional battery backup and can be configured both horizontally and vertically. The digital versions both have a display of air velocity in metres per second (m/s) or feet per minute and have a 3 digit display. The digital Versions of the A and C series have a vertical configuration only. The A and C series have three optional extras; a surface box mounting (a plastic enclosure to mount the face plate and avoid profile cutting and service panel), an alarm relay (a remote alarm that can be triggered from a replay controller on the PCB), and a battery backup which triggers the red LED alarm. It does however remain fully functional for up to 12 hours after losing power.
