Introduction

Scope of the Manual

This manual provides instructions for the installation,

maintenance and parts ordering for SS600 Series

noise diuser.

Product Description

SS600 Series noise diuser 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

muer for compressed air exhaust.

The all stainless steel construction of the

SS600 Series provides excellent protection from

corrosion while the porous stainless steel bae

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.
