For optimized safety, there is the accessory nGUARD Control which controls and monitors the flow. A completely unique VAV system with proactive control of the damper so that the flow always maintains the set value without time delay when changing the working opening of the sash window. Energy-saving automation, nGUARD Control Pro, which automatically closes the sash window when there is no presence in front of the fume cupboard, saves both money and the environment.

Contact your local distributor or NLT directly for more information and consulting.
