Products | ASME Code Pressure Filter Vessels - Coalescing Filters to 740 psig

Series R40- Enameled Carbon Steel

Series R42- 304 Stainless

Rugged Enameled Steel or 304SS Construction
Series R40 coalescing pipeline filters are fabricated from rugged enameled carbon steel, (R42 are 304SS), designed, constructed, and stamped in accordance with ASME Boiler and Pressure Vessel Code requirements for unfired pressure vessels. Any model can be modified to more exactly fit your needs.

Intake Air Flows to 150,000 SCFM Std.

ASME U Stamp Std., Nat’l. Board Registered

Exceptionally Low ΔP, High Flow
Pleated Element Design - Exceptional Useful Filter Area
Hinged Flange and Lift Lug Std., Service Access W/O Breaking Connections
304SS Throat Safety Cages, ΔP Taps Std.

Connection Sizes from 1" to 12"
Male NPT or raised face flange in-line connections are std. Alternative orientations and sizes are available. An elevated discharge connection is shown below. A hinged blind face flange closure assembly with lift lug is standard.

 

Coalescing Filter Media
Sparks™ #907 media is composed of microfine borosilicate glass fibers bonded with phenolic resin. Together with a textile prefilter and a final drain layer, these pleated elements are remarkably effective at coalescing fine entrained oil and aqueous vapor mist from air/gas flows with very low ΔP. Experience has demonstrated high removal (over 90%) in dealing with 1.0 to 0.3µ aerosols. Other optional filter media such as #926 exceeds 95% removals. Individual performance will vary with the specific viscosity and vapor pressure of liquid contaminates.

 

Options
Models R40-0202-RF-020 and larger include CS leg supports. (add 18" to OH) Carbon steel support legs in any length, gauges, special finishes, and head lift assemblies are optional on any model. Call for information on vessels having other pressure services, 304SS, or other materials of construction. We have several different sizes of coalescing pipe filters in stock

Filters that saved a plant from shut down. Two ASME code certified coalescing filter-separators solved a very serious problem. They now protect an existing Downstream unit filled with costly molecular sieve (over $200,000) from liquid contamination in the gas stream. Together with a second Sparks™ filter-coalescer, this unit employs an automatic drain system and removes over 500 gallons of liquid per day with over 99% efficiency.
