AFA4000/1 Airflow Monitor / p.5
1. Introduction
The TEL AFA4000 is a system for controlling and monitoring airflow in industrial and
educational fume cupboards and biological safety cabinets for user safety. The AFA4000
airflow monitor and controller is available with optional Auto Sash integration. Using the
Auto Sash with the AFA4000 controller means you will no longer need a separate Auto
Sash keypad.
The AFA4000 user interface is full colour, intuitive and is easy to navigate. It features a
simple two-step calibration process with on-screen prompts to guide end users. The
unrivalled reliability of the AFA4000 means that once calibrated, you will not need to re-
calibrate in the future. The AFA4000 has in-built communications as standard and it can
be used with either Modbus or BACnet protocol.
Featuring an innovative hot wire sensor, the AFA4000 has no inherent drift meaning that
the sensor will provide stable readings over many years of operation ensuring reliability
and safety.
The AFA4000 has full alarm diagnostics and test functionality, a sixty-minute timeline of
environmental conditions and field-upgradable software, with password protected
menus and diagnostic menus to aid installation and commissioning.
This manual covers the AFA4000/1 and AFA4000/1/AS airflow monitors.
