Coalescer Cartridge Series Description


Model Number System: Refer to the box at left. The one or two digit Series Designator relates to the approximate micron rating of each model coalescer cartridge. Note that this is a Normans rating and should be used for reference

The "0", "2", and "4" Series all-fiberglass cartridges are rated at 25, 5, and 3 microns respectively. The "2" and "4" Series are commonly used with diesel and other fuel oils, and are a compromise between filtration efficiency (cartridge life) and water removing capability. They coalesce gross water, but normally do not remove fine water haze.

The all-fiberglass "6" Series was originally developed for jet fuel service (the original MIL-F-8901 specification). It has a 2-micron rating and met the First Edition API 1581, Group I (non-additive) requirements. It has proven to be the most cost effective design in some jet fuel applications. "6" Series cartridges are also used in gasoline filtration service. However, it should be noted that the powerful detergent additives in most automotive gasolines reduce the coalescing capability of this and other cartridge designs.


"83" Series Cartridges: The 1-micron rated "83" Series is a pleated media / fiberglass cartridge originally designed to meet the requirements of First Edition API 1581, Group II (jet fuel with additives). Over the years the very practical "83" Series cartridges have become the most widely used design in applications including gasoline, condensate, and insulating oil filtration.

"85" and "87" Series Cartridges: meet the exacting requirements of the Third Edition. The "85" Series is rated at 0.5-micron while the "87" Series is rated at 0.3 micron. Both incorporate multi-layered pleated media. The "85" Series is used in Class A and Class B (fixed) installations and has consistently shown superior dirt holding capacity in the field. The "87" Series is qualified for both Class B (fixed) and Class C (mobile) applications.

Cartridge Dimensions: 6" diameter cartridges are the current industry standard. They are offered in lengths of 11", 14", 22", 28", 33", 38", 44", and 56". However, not all series are available in all lengths or in both end cap designs. Contact us for details. 4" diameter cartridges are also offered for use with older equipment. They are available in a variety of lengths ranging from 8 to 40 inches.


General Specifications

  • Aluminum center tube
  • Buna-N gaskets
  • Injection molded end caps are standard on 6" diameter open end cartridges
  • Aluminum end caps are standard on 6" diameter threaded base coalescer;
  • All 6" diameter cartridge end caps are bonded directly to the media with high strength epoxy
  • 4" diameter cartridge end caps are molded polyester resin or injection molded.

Coalescer Cartridge Construction


Velcon single-unit coalescer elements are offered with Threaded Base or Open Ends and with Fiberglass Media or Fiberglass and Pleated Media combinations.

Threaded Base Coalescers are recommended for use in most applications. They simplify installation and replacement by eliminating the need for cover plates, center plates, nuts, washers, and gaskets. They are for use inVelcon® and other make filter / separators. Threaded base adapters are available to convert vessels presently using open end elements.

Open End Coalescers are offered with single unit construction which reduces the number of gasket seals and improves overall reliability.

All-fiberglass Media Coalescers combine depth particulate filtration with a deep coalescing structure. All-fiberglass designs have successively finer media layers to achieve depth-type fitration of particles.

Combination Fiberglass and Pleated Media Coalescers remove particles primarily in the high surface area pleated core. They have one or more layers of pleated media inside a cylinder of molded fiberglass laminations to provide an extended surface area for particuate filtration. Pleat corrugation and separation materials are used to keep pleats open for full utilization.

Coalescing and filtration performance depends largely on the fiber diameter and buk density of the fiberglass media. Both the All-Fiberglass and the Combinatiion coalescer cartridge designs incorporate phenolic resin impregnated fiberglass media. Several grades with fiber diameters ranging from 1 to 10 micrometers are used in various combinations to achieve desired results.Velcon's latest coalescer designs (85 and 87 series cartridges) achieve even higher filtration and coalescing efficiency by incorporating pure micro-glass fibers with diameters of less than 1 micrometer in the pleated media.

Coalescer Cartridges

Used as first stage elements in Filter/Separators. 
Remove particulates and coalesce
water into large water drops.

Coalescer Cartridges - Separator Cartridges

Separator Cartridges

Second stage elements in Filter/Separators. 
Repel coalesced water drops which then
collect in the sump for easy removal. 
Available in Teflon Coated Screen,
Pleated Paper Media, or Synthetic Media.



Pleated Paper Cartridges

Corrugated pleated media with large
surface area for filtration  of granular contaminants.
Progressively finer layers of fiberglass filter
colloidal or slimy contaminants.

Pleated Paper Cartridges - Clay Canister Cartridges

Clay Canister Cartridges

Attapulgus clay canisters for removal of
surfactants from jet fuel and other petroleum products.



AQUACON Cartridges

Filter particulate matter and absorb water
with great efficiency.  Water capacity is
approximately 40 times greater than 2" diameter
monitor cartridges.  Also provide positive,
surfactant-proof protection against water slugs.

AQUACON Cartridges - CDF Cartridges

CDF Cartridges

Absorb water and filter solids from
Avgas and Jet Fuel.   Provide positive
protection  against water slug transmission. 
Performance is not affected by surfactant
