These filters and filter-silencers are availablewith a variety of filter panels, each with itsown restriction characteristics. To reflect thatfact, the total pressure drop for a specific filterapplication is the sum of two pressure dropvalues:

1 The first value is the restriction that canbe attributed to the filter housing withoutfilter panels. This value is found in thegraphs at right.

2 The second value is the restrictionthrough the filter panel media. Thesevalues are taken from the table below.

The pressure drop values for the filter panelsare listed in the table as pressure drop ininches of water gauge at various flow ratesin CFM. The housing pressure drop isshown in graphical form as a function of airflow in CFM versus pressure drop in inchesof water gauge.

To avoid confusion, pressure drop values inthe graphs include pipe entrance pressuredrops from the atmospheric end of the inletpipe. These drops are significant,contributing as much as 75% of the totalpressure drop, and should not be attributedto the filter. Adding the filter transfers thesepressure losses to the interior of the filterhousing. A pressure drop measurement atthe pressure tap on the filter outlet reflectsthe total:

FH SeriesFilter

FSH Series Filter-Silencer

The FH and FSH series use standard panelfilters, which are available in a variety oftypes and efficiencies. The supports for thefilter frames inside the housingsaccommodate conventional 2" deep single-panel filters or, for critical service, twosingle-panel filters staged in series. In thecase of dual-stage systems, use a high-efficiency final filter and a less efficientprimary filter. The FSH series has anintegrated silencing section for applicationsthat require moderate noise reduction.

For centrifugal compressors, blowers,engines, and gas turbines. For reciprocatingcompressors, ask Universal Silencer for recommendations.

FRH SeriesFilter

FCRH Series Filter-Silencer

These products are similar to the FH andFSH series, except that the FRH and FCRHseries are two-stage filters. The secondstage consists of a battery of 12 cartridgefilters for each 20" � 25" � 2" prefilter.

The high-efficiency P-5 cartridge filters havethreaded ends that screw into individualreceptacles. As each P-5 filter is removedand replaced, less than 4 in2 is exposed tothe flow of unfiltered air, so “hot swap”changeouts (while the system is inoperation) are an option for these units.

FASH SeriesAbsolute Filter

The FASH Series Absolute Filter-Silencerrepresents the ultimate high-efficiency airfiltration for industrial applications. The unituses first- and second-stage elements,having a combined depth of 20", to provideexceptional efficiency on ultra-fineparticulates and a large surface area for lowflow resistance and high dirt-retentioncapacity. Filtration efficiency is 99.97% onparticles 0.3 microns.

Instead of a conventional gasket seal, theFASH utilizes a unique fluid seal for the finalfilter. A channel on the downstream side of theP-12F final filter holds a stable silicon gel fluid.The frame has a projecting tongue which isimmersed in the fluid. The result is a 100%bypass-free system.

For economy, the filters are staged, so thatthe less expensive pre-filter “roughing” padand primary filter can be changed morefrequently than the final filter. Under typicalconditions, the pre-filter will requirereplacement about once a year, while thefinal filter may provide two to three years of service. Specification details for the P-8pre-filter and P-12F final filter can be foundon page 8.7.

The FASH features an integral silencingsection for a moderate degree of noiseattenuation. The unit is constructed ofheavy-duty steel sheet and plate, weldedthroughout, making it a rugged, long-lasting,trouble-free air filtering component.

All models are equipped with removableweatherhoods, pressure tap, and flangesdrilled to match 125/150 lb ANSIspecifications. Inside and outside surfacesare primed and given a finish coat of enamel paint.

Suitable mounting legs may be fitted in thefield, or quoted upon application.

For centrifugal compressors,blowers, and gas turbines.

Nominal capacity is based on exit velocity of approximately 5,000 ft/min. Filter element capacity may be greater, but this is unrelated to unit capacity. 4" deep filter frames willhold single elements or dual elements. Weights do not include the weight of the filter elements. Weight is measured with steel weatherhoods. Louvered weatherhoods reduceweight by 7 lb per filter opening.

P-8 SeriesPrefilter

P-12F Series Final Filter

For New Units—MeasuringPressure DropWhen new filters or filter-silencers areinstalled, make the following two pressuredrop measurements and record the resultsfor future reference:

1 Measure the pressure drop with all filters installed.

2 Measure the pressure drop with the P-8pre-filters removed, but the P-12F finalfilters installed; this gives the pressuredrop across the final filters.

3 Subtract the second value from the first to find the pressure drop across the pre-filters.

Polyester Pad ReplacementReplace the polyester pad when visibly dirty.

Filter ReplacementAfter the units have been in service and thefilters are loaded, determine whether thefilters need to be replaced as follows:

1 Measure the pressure drop with all filtersinstalled and subtract the valuemeasured at installation, when the filterswere clean, to find the pressure dropacross both loaded filters.

2 Measure the pressure drop with the P-8pre-filters removed, but with the P-12Ffinal filters installed; subtract the valuemeasured at installation, when the finalfilters were clean; if the difference ismore than 2", replace the final filters.

3 Subtract the second value from the firstto find the pressure drop across the pre-filters. If the difference is more than 2",replace the final filters.

* The polyester pad (part number 81-0400) is a 2" thick “roughing” filter that fits on the face of the P-8 prefilter. It may be purchased separately in cartons of 12 and shouldbe replaced when it is visibly dirty. Follow the service instructions for replacement.

CCS/CS/CCF/CFFilter Elements

Pleated Paper ElementSpecifications

High-quality industrial grade filterpaper—pleated and oven-cured duringproduction.Oven-cured plastisol end caps withmolded sealing beads.Media efficiency: 99.5% on 2 microns; 97% on 1 micron.Maximum operating temperature: 200°Ffor units with ¹⁄₂" through 16" pipe sizes.

Service InstructionsBecause of the low cost of the paperelement, it is generally treated as aconsumable and replaced when dirty.However, depending on customerpreference, the paper element may becleaned with compressed air and reused.

Compressed Air CleaningCarefully direct compressed air (100 PSImaximum) through the dry element,opposite the normal direction of flow. Aftercleaning, inspect carefully for holes orcracks. If damaged, replace element.

Pleated Felt ElementSpecifications

Durable polyester felt media—pleated.Oven-cured plastisol end caps withmolded sealing beads (larger elementsfor pipe sizes 10", 12", 14", and 16" havemetal end caps with closed cell rubbergaskets).Media efficiency: 99% on 10 microns.Maximum operating temperature: 200°Ffor units with ¹⁄₂" through 8" pipe sizes,250°F for units with 10" through 18" pipesizes using elements with metal end caps.

Service InstructionsPleated felt elements may be cleaned withcompressed air (as described for paperelements) or water and reused.

Water CleaningRap gently to dislodge accumulated dirt,soak thoroughly approximately 15 minutesin warm water and mild detergent. Rinsethoroughly under low pressure water. Airdry—do not dry with compressed air. Aftercleaning, inspect carefully for holes orcracks. If damaged, replace element.

Wire Mesh ElementSpecifications

Galvanized wire-mesh media—corrugated construction.May be cleaned and reused indefinitely.Wire mesh elements are considered“roughing” filters and are notrecommended for applications whichrequire efficient filtration of fine particles.Approximate efficiency: 93% on 10microns. Efficiency will vary withelement oil or adhesive coverage.Maximum operating temperature: 200°F for ¹⁄₂" through 16" with oil-freeadhesive (flash point of adhesive is235°F) and 300°F for ¹⁄₂" through 16"without adhesive.

Service InstructionsNew elements are delivered pre-treated withUniversal Silencer’s oil-free adhesive. Seethe back page for details. For best efficiency,wire mesh elements must be retreated aftereach cleaning. Spray the element on bothsides with Universal Oil-Free Adhesive, P/N81-0323, following the directions on thecontainer. For oil treatment, dip the elementin SAE 30–50 motor oil and drain thoroughlybefore using.

CleaningTo clean wire mesh elements, wash insolvent or warm water and detergent in acontainer large enough for completeimmersion of element. Rinse completely,drain, and either air dry or use compressedair. After cleaning and drying, retreat theelement with oil-free adhesive or oil asdescribed.

Three types of filter elements are availablefor Universal’s cartridge filters and filter-silencers. Pleated paper elements providethe highest efficiency and are consideredstandard. Pleated felt and wire meshelements are available for less demandingservice with respect to efficiency. The threetypes of elements are completelyinterchangeable and will fit all CCS, CS, CFor CCF filter housings.

ILFV SeriesVacuum Service In-line Air Filters

All models have a ¹⁄₈" FNPT tap for installation of a gauge or manometer to monitor pressure drop. The C dimension is clearance required to remove elements. Non-ASMEcode construction is suitable for 15" Hg vacuum. Not applicable for pressure applications. Rated capacity is based upon flow velocity of approximately 5500 ft/min. If pressure drop allowance permits, capacity may be increased by as much as 50%. Flange connections are drilled per ANSI standard for each size. Sizes 2" through 4" arestandard with male pipe threaded inlet and outlet fitting (MNPT). Sizes 5" through 14" are standard with plate flanges drilled to ANSI standards (dashed lines on sketch).Weight does not include filter elements. Refer to page 8.14 for filter element details.

*Specify “P” at the end of part number for paper element or “F” for synthetic felt.

Filter ElementsPleated paper elements offer the highestefficiency and are considered “standard”for the ILFV series units. Pleated feltelements are also available for lessdemanding service. Both element types are completely interchangeable and will fit in any ILFV housing.

Universal’s Filter Restriction Gauge providesa convenient, accurate means of monitoringfilter pressure drop as the filter elementbecomes increasingly loaded with dirt.In-line air filters are standard with threadedconnections for directly mounting the gauge.See p. 9.15 for a complete description.
