Parker Velcon VF-609 Filter Housing, for Aquacon Filter Cartridges


The VF-609 is a versatile filter housing with bolted cover, designed for use with several different high performance Aquacon filter cartridges. Refer to the cartridge selection table on the reverse side.

Aquacon cartridges filter out water by chemically locking it into layers of super-absorbent media. Water removal efficiency is not affected by surfactants or additives, andonce captured, the water cannot be squeezed out. Water capacity is as much as 11⁄2 quarts, depending on the flow rate. These cartridges also effectively filter out dirt, rust and other particulates.

As a cartridge reaches its water- holding limit, the media expands very rapidly and restricts the flow. For fuels, the flow will completely stop, giving positive shut-off and guaranteeing water will not get downstream. For oils and other high viscosity liquids, the pressure drop will rapidly increase, signaling the need to change cartridges.

Over Pressure Protection:

When exposed to a high concentration of water, the differential pressure across an Aquacon cartridge will immediately increase. Pressure bypasses or other means to limit the inlet pressure to 75 psi (5 bar) should be installed to prevent the cartridge from collapsing.


  • Aquacon cartridges remove free and emulsified water from fuels to less than 5ppm.
  • Filtered water is chemically locked in and can’t be squeezed out.
  • Provides Protection against 'slugs' of water.
  • Pressure Increase signals cartridge change.
  • 0.5 Micron Particle Protection @ 98%+ Efficiency.


  • Jet Fuel
  • Avgas

NOTE: For non-EI qualified applications. Housing does not meet EI1596 or EI1581 qualifications.

CAUTION: Do not use Aquacon absorbent cartridges (AC, ACO or AD Series) with pre- mixed jet fuel containing anti-icing additives, or with gasoline/alcohol blends.

CAUTION: To protect the fuel system, including the VF-609 and other components, be sure to install pressure relief valve(s).
