Product Benefits
Safety and compliance
Protecting your staff from potentially hazardous fumes and substances and ensuring you stay compliant.
Energy and cost savings
The TEL Volumetric Controller reduces the volume of air taken from the fume cupboard when it is not being used, reducing energy usage by up to 85%, considerably reducing costs.
Carbon emissions reduced
With many organisations having to meet carbon reduction targets, TEL’s Volumetric Controller reduces energy wastage, ensuring reductions in carbon emissions.
Choosing the right model
4NM Fumecupboard Actuator
Modulating damper actuator for adjusting dampers in technical building installations.
6NM SuperCap Actuator
Modulating SuperCap rotary actuator with emergency control function and extended functionalities for adjusting dampers in technical building installations and in laboratories.
AFA1000/AHU
The AFA1000/AHU model is a wall mounted pressure controller suitable for controlling the duct pressure of an AHU using an inverter drive.
AFA1000/BLD
The AFA1000/BLD is a wall mounted fresh air bleed controller suitable for controlling the VAV system duct pressure using a fresh air bleed damper or fan inverter drive.
AFA1000/E
The AFA1000/E is a digital airflow VAV controller available with a range of remote unique airflow sensors that are used to measure face velocities or duct velocities. The AFA1000/E is available fully flush (MK2) or semi flush (MK3).
AFA1000/E Dual Output
The AFA1000/E has a dual output allowing control of a secondary function such as Supply Air damper/inverter control or Fresh Air bleed damper control.
AFA1000/RM
The AFA1000/RM model is a wall mounted room differential pressure controller suitable for controlling the supply air into a room using a damper, valve or inverter.
AFA3000/E
The AFA3000 VAV controller has been specifically designed for Venturi Valve fume cupboard applications.
The controller will adjust the valve to the desired flow based on sash position. The mechanically pressure independent valve will accurately control and maintain design flows (as the system pressure/sash position changes). As the valve cannot detect changes in the face velocity of the fume cupboard , we incorporate one of our velocity sensors that will increase the flow of the valve if the face velocity drops below desired values.
AFA4000/E
The AFA4000/E is a pioneering airflow controlling system developed to ensure the safety of users, working with industrial and educational fume cupboards and biological safety cabinets.
ECON Damper
A precision engineered single blade butterfly damper designed for many years of maintenance free movement. The clear bodied design allows you to check for any debris caught on the internal blade.
