SS600 Series Noise Diffuser
Product Description
SS600 Series noise diffuser is a compact, repairable unit that spreads out
high velocity discharge from steam traps while dampening the level of noise
associated with steam trap cycles. SS600 Series are also used for blowdown
valves, air cylinders and muffler for compressed air exhaust.
The all stainless steel construction of the SS600 Series provides excellent
protection from corrosion while the porous stainless steel baffle allows
condensate discharge without back pressure.
The snap ring design allows for easy in-line element replacement.

Principle of Operation
The SS600 Series noise diffuser is installed on the outlet side of steam
traps, valves or other equipment that discharges high velocity steam,
condensate or air to the atmosphere. The baffle is constructed of a fine
stainless steel wire mesh, similar to steel wool. The porous mesh breaks down
the high velocity discharge which dampens the sound significantly.
Installation
WARNING
Personal injury or system damage may result if this diffuser is installed
where service conditions could exceed the limits given in the Specifications
section.
Additionally, physical damage to the diffuser may result in personal injury
or property damage due to escaping of accumulated gas. To avoid such injury
and damage, install the diffuser in a safe location.
Do not install diffuser in such a manner that may cause accidental exposure
of discharge.
- Before installing the SS600 Series, blow all dirt and scale from apparatus and piping.
- Install the SS600 Series on outlet side of steam or air trap.
- Orient the SS600 Series to discharge toward floor or other suitable enclosure.
