For power regulation, the negative pressure unit is supplied with a manual stepless regulation.
A necessary filter change is indicated by a manometer.
Control SRE connect
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 negative pressure unit is supplied with a control via a touch display in order to measure and regulate the negative pressure or the volume flow.
The negative pressure is measured between the contaminated area and a reference point (adjoining rooms) to be defined and is kept at the set point by continuous speed control of the electric fan.
The volumetric flow is measured in the unit and is kept at the set point by continuous speed control of the electric fan.
Manual control is also possible.
A filter sensor 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.
A necessary filter change is indicated on the display.Options
