Stay
New® Spin Filter
Dollinger
StayNew® Spin Filter Systems are designed to beat tough
contaminants like fly ash, soot, dust, sand, grit, saw-dust,
rain and snow and operate continuously. They provide clean,
smooth air flow in a wide variety of hostile environments
and conditions – even sandstorms and volcanic fallout.
All smooth-flow compressor and blower installations can
benefit from the performance and economy of a multi-stage
StayNew® Spin Filter System. Their self-cleaning feature
makes these systems ideal for locations where heavy contaminant
loading is a problem for air intake filtration. Their strong
corrosion-resistant construction means you can install them
in locations where conventional filters are not suitable.
Dollinger has designed these systems to help you cut costs
with pre-engineered, modular units to fit most applications.
We can also custom design units with a large selection of
accessories and options.
Examples of installations include:
Two single-stage StayNew® Spin Filter Banks,
each rated at 42,270 SCFM capacity, at a fertilizer plant.
Two 3-stage StayNew® Spin Filter Systems, each with an 11,630
SCFM capacity, at an electric utility plant.
A single-stage filter assembly with 13,750 SCFM capacity,
in the carpenter shop of a forest products laboratory.
Five special 3-stage systems, each rated at 510 SCFM, at
a sewage treatment plant
Three 3-stage systems, rated capacity 21,135 SCFM each,
at a coal-fired utility.
A 3-stage system with an 11,630 SCFM capacity, at a power
station.
A 2-stage system with a working capacity of 79,260 SCFM
at an Enhanced Oil Recovery facility.
StayNew®
Spin Filter Module
The
Dollinger StayNew® Spin Module, which is the heart of the
StayNew® Spin Filter System, is a compact mechanical separator
which can be used independently or in combination with secondary
filter elements in a variety of air filtration systems.
It is designed to conquer tough contaminants, providing
clean, smooth air flow in a range of applications and conditions.
The self-cleaning feature makes it ideal for locations where
heavy contaminant loading is a problem for conventional
air-intake filtration. The strong corrosion resistant construction
means the StayNew® Spin Filter Module can be installed in
hostile environments. In addition, it is unaffected by wide
ambient temperature variations – maintaining stability and
operational integrity from - 40°F to + 200°F. The StayNew®
Spin Filter Module is also safe for food service and has
received FDA clearance for food contact use (21 CFR 177.1520).
By greatly reducing dirt loading on secondary filter elements
in a system, the StayNew® Spin Filter Module provides long-term
economies by extending the service life of an air-intake
system. Used alone, it removes 98% of solid particles 15
microns and larger from an air stream. In addition, it will
remove up to 99.4% of moisture, whether in the form of liquid
mist or snow.
The standard StayNew® Spin Filter Module, VE-616-1220, is
a twin module. Nominally rated at 1,450 SCFM, it can successfully
accommodate flow rates up to 2,800 SCFM. The compact, lightweight,
modular construction of the unit allows for multiples to
be combined readily in a package to handle the most demanding
requirements. Also available for special applications is
a single module, VE-616-1210, The rated capacity of the
smaller units is 725 SCFM.
Design
and Construction
The standard StayNew® Spin Filter Module is mold-formed
of rugged, high-density polypropylene. Through centrifugal
force, contaminants are removed from the air stream as it
is drawn through tubes. The StayNew® Spin Filter Module’s
remarkable efficiency is the culmination of years of engineering
design, laboratory developments and field testing.
Efficient
Operation
Air enters inlet tube, striking stationary spinner and developing
high radial velocity. Inertial action forces contaminants
to the periphery of the tube, separating them from the main
air stream. Main air stream, now cleaned, exits straight
through the center discharge tube. Contaminants are carried
by a secondary discharge stream into a bleed duct system.
A blower is used to provide suction for the bleed air (approx.
10% of the inlet flow).
