Recoverable Sewn or Rubber End Filter
Elements.
Classic
radial fin textile media elements are unsurpassed for low differential pressure, dirt
holding capacity and efficiency. They stop particulates before they can move downstream.
Select either recoverable 10µ Sewn End Filter Elements or 10µ long life low cost
polyurethane rubber molded end elements, as your needs dictate to remove 98% of all
airborne dust and dirt. Unlike PVC, our urethane rubber ends have no phthalate elastomers
or other plasticizers. Dozens of alternative filter media are available for services
having finer micron retentions, elevated temperatures and/or aggressive chemistry.
An air gas filter housing should be designed
to operate with the practical simplicity and economics of an all-in-one stage filter
element.
Our filter
elements are specified to remove 98% of all dust, dirt, and other airborne particles. We
offer several quick and simple choices of standard replacement filter elements whose
physical size, and medial area to air flow ratios have been carefully calculated. Beyond
our standard selections, we offer more than 50 additional media for services into the
realm of the unimaginable.
We specialize in just one thing, filtering particulates and airborne mists from air and
other gaseous flows. We employ design principals which have been proven for over 60 years.
While it is true that customers occasionally utilize these filters for liquid filtration,
they are designed first and foremost for their exemplary performance in non-liquid flows.
You should know that we design and manufacture air/gas filters because we like to. We know
you'll be pleased with the filters you receive. If you're not happy, we're not happy.
Independent Laboratory Testing: We design to meet or exceed OEM
specs. All tests were conducted at independent labs.
Filtration efficiency indicates the size of the solid particles that the filter medium
will stop. Test results are shown for the two most common synthetic textile filter media,
#5 and #7. We can provide alternative media to meet services requiring retentions to 0.1
µ (micron) or temperatures exceeding 500 °F.
Media Permeability is the rate of air flow through the porous filter medium with respect
to the force needed to accomplish the flow. Textile filter media are typically 3 to 4
times less resistant to flow than cellulosic media. Textile filter media provide maximum
dirt holding capacity while minimizing the pressure drop across the media. The
permeability chart can help to size a filter element to your specific needs. Remember to
also consider the pressure drop caused by the filter housing and other classic pipe loses.
Polyester
Felt? its proven!
The lions
share of air intake applications are served admirably by Sparks #5 polyester felt
media. It's classic in its performance at 98% retention of particles measuring 10µ and
larger. Unlike cellulosic media, polyester felt has a significant value as a torturous
path material, affording superior flow characteristics over a longer useful life. It's
inherently lower resistance to flow permits more open fin spacing for greater dirt holding
capacity, and easier cleaning with an air hose or spray gun.
For
superior low micron capture, our #7 polyester felt can stop 98% of all particles 4µ &
larger.

304,318, 316L & Alloys
Series A10,
A30, A40, & A50 air intake filters offer time honored protection for
compressors, blowers, turbines, engines, and other air handling equipment. They are
fabricated from heavy gauge enameled steel. Weather hoods on models
A10 & A30 reject rain and snow. Any standard models
can be modified at your request to more exactly fit your needs. Connection Sizes 4" to 30"
Male NPT
(MT) or flat face flanges (FF) are std. Flanges match diameter & drilling for 150#
ANSI standard. Specify optional right angle base (AF) for side mounts, (FT) for female
NPT, (BE) for bevel or (PE) for square cut that match nominal pipe ODs, or (TE) for square
cut that match actual tube ODs. Increased or decreased connections sizes are also optional
on any model.

Accordion Elements w/Prefilter These washable pleated
textile media elements are rugged performers. They have very high dirt holding capacity
and high efficiency. In each unit, a single accordion filter element is placed over the
housings fixed perforated center tube. The "accordion" element is cinched
in place with a supplied retaining strap (not shown), and is then wrapped with a 90µ
prefilter blanket (not shown). Permanent housing gaskets (not shown) seal each end of the
filter element.
Rugged Enameled Steel or
304SS Construction
These air and
gas pipe line filters offer exceptional protection for compressed gas pipelines, air
dryers, pneumatic controls, and other pipeline equipment. They are fabricated from rugged
enameled carbon steel (series P20) or 304SS (series P22), designed, constructed, and
stamped, in accordance with ASME Boiler and Pressure Vessel Code requirements for unfired
pressure vessels. Any model can be readily modified at your request to more exactly fit
your needs.
Vacuum Filter Vessel (Non-Code)
Rugged Enameled Steel Construction Series P20 air and gas pipe line vacuum filters offer exceptional
protection similar to our pressure vessels. They are fabricated from rugged enameled
carbon steel. Any model can be modified at your request to more exactly fit your needs.
Connection Sizes from 1" to 12"
NPT or
raised face flanges (RF) in-line connections are std. Alternative orientations and sizes
are available upon request. A hinged swing bolt closure is standard.
