Universal Silencer Series RF Filter Silencer
|
| For use on intermediate and large size Positive Displacement
Blowers, Reciprocating Engines and Compressors. |
 Universal RF Series Filter Silencer is intended primarily
as a high degree reactive (chamber) type silencer of very rugged
construction as normally required on large slowspeed reciprocating
or positive displacement machinery, where broad-band noise attenuation
and inherent vibration-resistant structural strength is required.
Standard panel filters, as described elsewhere in this catalog,
are employed in the filter section. Four configurations are available,
as shown in the outline drawings below. RF Series are fabricated
of steel sheet and plate, welded throughout. Filter panels are
serviced and replaced through hinged access doors. Flanged connections
are drilled to match 125/150 Ib. ANSI specifications. Inside and
outside surfaces are given a shop coat of rust inhibitive
primer. The exterior may be finish painted in the field if desirable. |
