1.11 Noise data

The noise data* also refers to the aforementioned directive. Housing variations, unfavourable operating conditions and
many other things can lead to an increase in the specified catalogue values. Data that refers to certain distances (1, 2,
4 m) apply to free field conditions. With regard to installation, the sound pressure level can differ significantly from the
catalogue data, as it is highly dependant on the installation conditions, i.e. on the absorption capability of the room, the
room size among other factors.
1.12 ErP-Spezifikation
The relevant data for the ErP were determined as follows:
– Series HQ../HW.. Measurement in free inlet and outlet area in measurement category A
– Series HRF... Measurement at end of tube in measurement category C
All measurements were taken in compliance with DIN EN ISO 5801.
The resulting best point (BEP / best efficiency point) is defined as follows:

1.13 Type plate / Technical data

The product-specific technical data can be found on the type plate. The individual data is described below
using an example. With regard to flange motors (H..D 400/2/2; H..D 400/4/2; HRFD 450/2/2; HRFD 500/2/2;
H..W 560/4; H..W 630/4; H..D 630/4/4; H..D 630/8/4; Ø710 except H..W 710/6 & H..D 710/8), the motor type plate
must also be observed.
