  • Page 5: Introduction

    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.
