 Supply and exhaust air separated to prevent an air short circuit.
 Air inlet and air outlet sized according to the design and the required flow
rate.
Total of counter-pressures < 70 Pa. Please note the following here:
 Required flow rate: 4000 m
 At higher counter-pressures: Use an external fan
When calculating the pressure loss, note:
Pressure losses of components such as air baffles, air filters, blades, air

ducts
 Dirt deposits on components p increase pressure losses.
 The inverter can be disregarded when calculating the pressure loss
Using external fans
The ventilation system can be supported by an external fan. When using an
external fan with thermostat: The electrician is responsible for using an
appropriate external fan and installing it correctly in accordance with the
general conditions described above.
Please note the following here:
 The exhaust air can reach temperatures of up to +70 °C.
If the external fan is controlled by a thermostat:
Install the external fan in the air duct, centrally above the central inverter

Set the thermostat of the external fan to +40 °C

A timed relay ensures that the fan runs on for 5–10 minutes. This reduces
the switching frequency of the external fan.
Ensure that you have the required specialist knowledge or contact an expert
in ventilation technology.
