Parker Velcon, Aquacon ACO Series Aviation Fuel Filter Monitor Cartridges


Patented Aquacon Filter Cartridges have a unique high-capacity inner absorbent medium which removes all free and emulsified water from hydrocarbon fuels down to less than 5ppm in the effluent. Absorbed water is chemically locked into this medium.

When a cartridge reaches its water holding capacity, its accordian pleats swell and cause an increase in the differential pressure whch signals the operator to change the cartridge.

Solid contaminants are removed by the cartridges particulate filter media layers. The pleated accordian style design provides a large surface area for maximum dirt holding capacity. Models are offered for particle size filtration down to 0.5 Micron size with 98% plus efficiency. Performance is not affected by the presence of common active surface agents.

Compact aquacon cartridges are quick and easy to install. Models are available to fit most existing standard housings. Refer to cartridge selection table on reverse side.

Use form VEL1846 for cartridge changeout recommendations at flow rates less than rated flow.

  • Free and emulsified water removal to less than 5ppm
  • 0.5 Micron particle removal @ 985 Nom. Efficiency, suitable for Jet-A1 & AvGas
  • Provides protection against "slugs" of water
  • Pressure increase signals need for cartridge change
  • Use with existing filter housings
  • Outside-to-inside flow pattern
  • Replace cartridge when differential pressure exceeds 25 PSId
  • NOT for use with fuels that are pre-mixed with Anti-Icing Additives (FSII)

Current Production is Suffix 'R' - 7th Edition. (Previous versions include Suffix 'P' - 6th Edition etc.)
