Industrial silencers for blowers and fans
We have
designed
a series
of
Blower
discharge
silencers
for use
when the inlet is connected to the process, and the
discharge to the atmosphere. The required silencers are generally larger than the fan discharge
connection, and transitions from the fan discharge to the silencer are not included,
however, both inlet and discharge transitions are available on request.
The pressure drop at the rated flow is 1.00 inches of water. This
pressure drop has been corrected for the pressure recovery from the fan discharge
velocity. A 50% diffusion efficiency is assumed for the transition from the fan to the
silencer.
Model DF silencers can be supplied at extra cost with internals
removable for cleaning. This is recommended when the silencer is used with dirty gases.
Note that transitions from the fan discharge to the silencer inlet must
expand at an angle not exceeding 15o on the fastest expanding side. Also note
that "B" dimension must be parallel to the fan shaft
for good
aerodynamic
performance
and Blower Discharge
Silencers
.
Model CI Blower Silencers are designed to bolt directly onto the Blower or Turbine inlet flange directly. The Silencer includes a silencing element, followed by a plenum section, with one or two removable plates to allow access to the bolts, and 3/4" mesh inlet screen. Each Silencer has a resistance of 1.00" of water at its rated flow.
Model SI blower inlet silencer is designed to bolt directly to the blower inlet flange. This silencer includes the silencing section, followed by a plenum section large enough to accommodate the fan inlet opening. A removable plate is incorporated to allow access to the plenum for installation. A 3/4" mesh galvanized inlet screen is standard. Model SI has a built-in, all-metal, inlet box.
Model CI Blower inlet silencers can be supplied with a matching inlet filter. When clean, these filters will add aprox .15" H2O to the silencer at the silencer rated flow. Filter elements are removable and can be reused after cleaning. Filter is a cleanable viscous type of all galvanized construction and has a filtering efficiency of 93% at rated flow on 10 micron particles. CIF model numbers correspond to CI silencer model numbers.
