Ecodesign regulation
The MultiAir FC/FCE 4000P series meets the European
Ecovent 2009/125 / EC requirements according to the
Commission Regulation (EC) no. 327/2011, with perfor-
mance measurements made in laboratory - it can there-
fore not be expected that the same performance can be
achieved in practice.
On the blower, this is documented via the marking as
prescribed (example):
The marking indicates the required values according to
the standard, as explained below.
Ŋ
:
e
Total efficiency based on total pressure. The total pres-
sure is the difference between the stagnation pressure
at the blower outlet and the stagnation pressure at
the blower inlet. Stagnation pressure is the pressure
measured on moving air if this air was put to rest by an
isentropic process.
B:
An installation where measurements of the blower are
made with free inlet and a pipe connected to the outlet.
N - (Efficiency classification):
Parameter in the calculation of the target value for the
energy efficiency of a blower, with a specific applied
electrical input power at the optimal operating point.
VSD - Variable Speed Drive:
A frequency converter which continuously adjusts the
applied current so that the motor emits a mechanical
power with a torque and at a speed corresponding to its
current load.
All clean air blowers with outputs between 125W and
500kW must be equipped with a frequency converter to
meet the requirements of the Commission Regulation
(EC) no. 327/2011.
All calculations have been performed in accordance
with DS / EN ISO 5801: 2017.
