HIGH-CAPACITY Remote Pilot Regulators Ports: 3/4, 1, 1-1/4, 1-1/2 ...

INSTRUCTIONAL INFORMATION
For convenience in matching filters, regulators,
and lubricators, ROSS units are grouped in five
series of increasing flow capacity: Bantam,
Miniature, Mid-Size, Full-Size, MD4 TM , and
High-Capacity.
BANTAM Series. For flow to 30 scfm (14 l/s);
port sizes 1/8 and 1/4; tube fittings 1/4 to 10 mm.
Modular components are joined without pipe
nipples; ports are O-ring sealed.
MINIATURE Series. For flow to 20 scfm
(9.4 l/s); port sizes 1/8 and 1/4. Units joined by
pipe nipples.
MID-SIZE Series. For flow to 75 scfm (35 l/s);
port sizes 1/4, 3/8, 1/2. Connection of units by
either special modular connectors or by pipe
nipples.
FULL-SIZE Series. For flow to 155 scfm
(73 l/s); port sizes 1/4 through 3/4. Connection
of units by either special modular connectors or
by pipe nipples.
MD4 TM Series. For flows to 205 scfm, port sizes
3/8” to 3/4” units joined by positive-seal clamps.
HIGH-CAPACITY Series. For flow to 1000 scfm
(448 l/s); pipe sizes 3/4 through 2. Connection
of units only by pipe nipples.
FILTER RATINGS. ROSS conventional filters
have 5-micron ratings
compared to the usual industry
standard 40-micron
rating. 40-micron
particles have 500 times
the volume of 5-micron
particles, so it’s easy to
see why ROSS filters
clean best.
ROSS coalescing filters
5 Microns
40 Microns
COMPARATIVE SIZE
remove 99.98% of oil from the air as well as solids
as small as 0.3 micron. A filter as fine as this
should be preceded by a conventional 5-micron
filter to prolong its service life. Full-Size and
High-Capacity units have built-in differential
pressure gauges to show when the coalescing
element must be changed.
ROSS OIL VAPOR REMOVAL. Adsorbing filters
remove oil and hydrocarbon vapors that
cannot be removed by a coalescing or a general
purpose filter. It is used by industries such
as food processing, electronics, and instrumentation.
FILTER DRAINS. Most ROSS filters are available
with either manual or automatic drains. An
automatic drain discharges liquids accumulated
in the filter bowl whenever there is a pressure
drop. This ensures better filter performance and
simplifies maintenance, especially of filters in
inaccessible locations. ROSS strongly
recommends the use of automatic drains.
PRESSURE REGULATORS. Both piston and
diaphragm styles are available. All are self-relieving
and give accurate and consistent pressure
regulation. In the Miniature, Full-Size,
MD4 TM , and High-Capacity series precision
regulators are offered. They provide the most precise
regulation throughout their flow ranges.
Mid-Size, Full-Size, and High-Capacity series
also offer reverse-flow regulators for special applications.
LUBRICATORS. Two systems of introducing oil
into the air stream are used in ROSS lubricators.
Wick-feed. A porous bronze rod carries oil from
the lubricator bowl up to the air passage by capillary
action, and the air stream picks up the oil.
This is a self-adjusting system because the
amount of oil added to the air is in proportion to
the air flow.
Sight-feed. A riser tube brings the oil up to an
adjustable metering valve within a transparent
dome, where it then drips into the air stream. A
vane in the path of incoming air creates the small
pressure drop that draws oil up the riser tube.
This occurs even at very low air flows so that no
air passes without being lubricated.
CONSOLIDATED FILTER & REGULATOR. A
filter and a regulator consolidated into a single
space-saving assembly is available in all sizes
except the High-Capacity series.
Pre-assembled combinations of filter, regulator,
and lubricator units are available in all series.
