Description
Strainers are suitable for use with Ammonia, R-22, R-134a,
R404A, R-507 and other common refrigerants
These industrial type Refrigerant Strainers with stainless
steel screen are designed especially for the protection of R/S
control valves from foreign materials present in refrigeration
systems. The fine stainless screen mesh will collect particles
as small as .006" in diameter. Generous available screen
area allows maximum dirt capacity at minimum pressure
drop.
The use of a strainer is extremely important upon start-up
of a new refrigeration system where dirt, scale and weld
particles may be present in the system and are disturbed
and circulated when air testing or upon system start-up. Also
when an existing system is revised, any settled dirt or foreign
matter may be disturbed and circulated throughout the
system.
It is not safe to omit strainers ahead of the control
valves unless there is a certainty that the system will always
be clean.
If particles are too small to be removed by the strainer, it is
suggested that a R/S filter bag be installed where applicable,
periodically cleaned and removed when necessary.

When used with R/S control valves, the strainer may be
bolted directly to the inlet side of the valve to be protected.
Standard R/S flange nuts and bolts are used to connect the
strainer male outlet flange to the valve female inlet flange.
Consequently, only one pair of R/S standard male compan-
ion flanges is needed for a close coupled strainer and valve
combination.
