3.12 Noise level
The noise level of the
WAMFLO
®
dust collector without fan does not exceed the limit indicated by the 2003/10/
EC and 2006/42/EC Directives.
The measured equivalent continuous average sound pressure level LAeq is 78.0 dB(A).
All readings were taken at 1 metre distance from the equipment at 1.6 metres from ground, with compressed
air shots at 6 bar each 28 seconds, using a precision sound level meter.
Noise measurements of installed equipment may vary due to site conditions.
The noise level of the fans have been measured and they are given below.
All the data indicated in the Table concern the standard
WAM
®
tests:
- filter on DK hopper and Ø 100 mm L = 3000 mm tubes at intake and L = 2000 mm at outlet.
The noise levels of the
WAM
®
fans expressed in dB(A) are obtained by readings in the open field, at maximum
performance, at the 4 cardinal points at a distance of 1.5 m from the fan which is, in turn, placed 1.5 m off the
ground. During the test, the fan is ducted in accordance with Standards UNI EN ISO 5801:2009.
The user could obtain values different from those indicated, depending on the environment in which
the machine is placed.
It is always recommended to isolate the fan from the ground and ducting by using vibration-damping supports
and couplings. Avoid placing the fan in corners, near walls or on encased metal structures.
Silencers
A PASSIVE silencer can be coupled to the fan outlet so as to lower the noise at the outlet. The silencer is
always supplied with a adapter stub between the silencer outlet spout (rectangular) and the silencer (round).
Moreover, the silencer can be supplied directly coupled with the VPA choke valve. All the dimensions and
damping curves for the various models are indicated in Manual.
Important
The silencer is designed to reduce the noise at the fan outlet; if an outlet shaft or duct is installed
upstream the fan, these components can lower the noise which cannot be reduced by the silencer
supplied by WAM.
