The AFA1000/E Airflow monitor is supplied complete with a plug in type power supply for connection to a single gang socket. The mains supply should be fused 3A.
A desktop style power supply can be supplied with flying mains lead for connection to a fused spur or terminals.
For damper control a remote interface unit is supplied. The remote interface unit is supplied with a 2M figure 8 mains lead for connection to a single gang socket. The mains supply should be fused 3A. The interface unit provides power to the AFA1000/E and the damper actuator (30VDC unregulated).
The standard AFA1000/E is supplied with a remote type airflow sensor and has a plug in RJ11 socket on the rear of the case to accept the sensor cable.
A vent it can be supplied for connection to the Fume Cupboard inner sidewall, this comprises of 1M of 25mm vent tube, a 25mm Bush and Coupling and box lid. See EVK on accessories page.
The standard length of a remote type sensor cable is 2M, a 5M version is also available. Custom lengths can be supplied on request.
The AFA1000/E can be supplied with configuration software and cable for connections to a laptop for diagnostics and configuration of the monitor or for connection via a local Modbus RTU network for remote logging with real time graphical displays using the AFA Network software or for direct connection to a BMS system. See Modbus RTU Comms on additional features page.
The AFA1000/E MK3 can be supplied with a custom overlay (details on request).
The AFA1000/E VAV Controller range includes the following accessories:-
The AFA1000/E VAV Controller will operate with any of the following airflow sensors:-
