VAV Controls
By TEL
TEL VAV controls are designed specifically to provide variable airflow volume and ensure the safety of users working with fume hoods and biological safety cabinets.
Converting fume hoods to VAV can reduce volumes by up to 85%, reducing both energy costs and carbon emissions.
TEL offers a full retro fit service and is making a considerable impact on how organisations meet their carbon reduction targets.
Suitable for
- Pharma labs
- Chemical labs
- Pathological labs
- Biochemical labs
Airflow Monitors
TEL 1000/1
The AFA1000/1 is a digital airflow monitor designed for applications where pushbutton functions are not required and is available with a range of remote unique airflow sensors used to measure face velocities or duct velocities. Available fully flush (MK2) or semi flush (MK3).
TEL 4000/1(CAV)
The AFA4000 is a pioneering airflow monitoring system developed to ensure the safety of users working with industrial and educational fume cupboards.
TEL 1000/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.
TEL 4000/E (VAV)
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.
TEL AFA5000 Room Space Controller
The Room Space Controller communicates directly with fume cupboard systems which enables the AFA5000 to measure precise airflow requirements of fume cupboards allowing air to be controlled exactly according to need, minimizing energy consumption and allowing you the peace of mind to get on with the job at hand.
