IoT (Internet of Things) => Devices with SRE connect control can be remotely controlled and monitored with any Internet-enabled PC, mobile phone or tablet.

For power regulation, the NPU is supplied with a control via a touch display to measure and regulate the negative pressure and / or the flow rate.

The negative pressure is measured between the work area and a reference point to be defined (adjacent rooms) and kept at the set point value by continuous speed control of the electric fan.

The volume flow is measured in the device and kept at the set point value by continuous speed control of the electric fan.

Likewise, a manual control is possible.

A filter sensor (option with connect BASIC) monitors the particle concentration in the exhaust air and triggers an optical and acoustic alarm if a value of ca. 100 particles per liter is permanently exceeded.
