Exhaust air elements

Centro-M-APB

Manual model. For use in systems with jointly variable volumetric flows. Fixed air volume setting by pushing out sealing plugs in each exhaust air element.

Centro-E-APB

Electric model. With electro-thermal servomotor for switching between basic and demand-based ventilation. Fixed air volume setting of the basic ventilation by pushing out sealing plugs in each exhaust air element. Demand-based ventilation automatically via servomotor.

Centro-H-APB

Model with automatic humidity control.

Barrier-free product as the fan switches itself on and off automatically. Once the exhaust air element has been installed, the unit regulates to the current room humidity (relative humidity). This humidity value is saved as the first reference value. The reference value does not have to be specified manually.

If the room humidity rises by 7 % within 2 minutes, the exhaust air element switches to full load operation (demand-based ventilation). If the relative humidity falls below the reference value during operation, the newly established reference value is saved. The exhaust air element then automatically switches back to base load operation.

If the humidity does not fall below the reference value within 60 minutes, the unit continues to operate for 15 minutes in nominal load and then switches to base load operation or off. The exhaust air element then automatically switches back to base load operation.

Demand-based ventilation automatically or via a switch (for example light switch). After manual switch-on (light switch) the exhaust air element runs with a start delay of approx. 1 minute with demand-based ventilation (full load). After manual switch-off, the exhaust air element continues to run in nominal load operation with an overrun time of 15 minutes (valve closing time approx. 2 - 3 minutes).

Fixed air volume setting of the basic ventilation by pushing out sealing plugs in each exhaust air element. Demand-based ventilation possible via a switch (e.g. light switch). For function: Wiring diagrams.
