3 Description
3.1 Intended use
Nederman Fan Inverter is a frequency controller that
is preprogrammed with an extraction fan applica-
tion for Nederman fans. It is equipped with a pressure
sensor and a PID controller that can maintain a con-
stant negative pressure in an extraction system, and
as a result, maintain an almost constant airflow in ex-
traction devices. The fan capacity is regulated to the
actual demand of the airflow, depending on the num-
ber of extraction devices in use at the same time.
The benefit of using Nederman Fan Inverter is that it
reduces running costs, heat loss to the atmosphere
and noise levels. It conserves energy and improves
performance by regulating the system’s power usage
as the demand from extraction devices increases or
decreases.
3.2 Dimensions and technical data
See the VACON 100 Installation Manual for informa-
tion about Fan Inverter dimensions and technical data.
4 Pressure Control
Nederman Fan Inverter uses an integrated pressure
sensor and pressure taps in the duct work. This makes
the system operate more efficiently by measuring the
system pressure, and adjust the fan speed in order to
maintain a constant pressure. If the system pressure
is low, Fan Inverter can increase its fan speed and vice
versa.
