Aviation Fuel Water Separation

Coalescer elements

Coalescer elements are designed to coalesce free water and to remove fine solids from aviation fuels and other hydrocarbons. Coalescers are deployed at the first stage in a filter/ water separator, when fuel enters the vessel.

P-Type according specification EI 1581 6th Edition, Category C

Aviation P-Type coalescer elements are intended for use in filter/water separators on refuellers, hydrant dispensers, other mobile and stationary refuelling equipment. Coalescer elements are also used in industrial application in fuel depots, refineries or barges, where high water removal efficiency plays a crucial role.

  • Qualification: EI 1581 6th Edition, Category C
  • Nominal filtration: According to EI 1581 6th Edition

P2-Type according  specification EI 1581 6th Edition, Category C

Aviation P2-Type coalescer elements are intended for use in filter/water separators on refuellers, hydrant dispensers and other mobile refuelling equipment. They are characterized by an excellent dirt holding capacity and water removal efficiency.

MIL-Type according specification EI 1581 6th Edition, Category M

Aviation MIL-Type coalescer elements are intended for use in filter/water separators on refuellers, hydrant dispensers, other mobile and stationary refuelling equipment. They are characterizied by an excellent dirt holding capacity and high water removal efficiency.

MIL2-Type according specification EI 1581 6th Edition, Category M

Aviation MIL2-Type coalescer elements are intended for use in filter/water separators on refuellers, hydrant dispensers and other mobile refuelling equipment. They are characterized by an excellent dirt holding capacity and water removal efficiency.

CS-Type according specification EI 1581 6th Edition, Category C

The two stage filter system comprises a coalescer and a separator element. The coalescer/separator filter system removes water and contaminants from aviation fuels and other hydrocarbons.

Aviation CS-Type coalescer/separator filters are intended for use in Vertical Filter Housings (VFH) on refuellers, hydrant dispensers, other mobile and stationary refuelling equipment.

Separator elements

Separator elements are used as the second stage of a high-performance separation in filter/water separators. After emergence from the coalescer, aviation fuels pass through the pores of the separator element while water droplets are repelled by the hydrophobic separator surface. Water droplets settle into the filter/water separator sump to be drained off.

60-Type according specification EI 1581 6th Edition, Category C

Aviation separator elements are available with a Teflon®-coated screen or synthetic mesh. Separator elements with a Teflon®-coated screen can be reused after a cleaning during coalescer element changeouts. Small areas of damage can be repaired. It is recommended that separator elements with a synthetic mesh are replaced during coalescer changeouts.

60-MIL-Type  according specification EI 1581 6th Edition, Category M

Aviation 60-MIL-Type elements are fitted with a Teflon®-coated screen. Separator elements with a Teflon®-coated screen can be reused after a cleaning during coalescer element changeouts. Small areas of damage can be repaired.

FW6-/FW6-T-Type according specification EI 1581 6th Edition, Category C, Type S & S-LW

Aviation elements are fitted with a Teflon®-coated screen. Separator elements with a Teflon®-coated screen can be reused after a cleaning during coalescer element changeouts. Small areas of damage can be repaired.

FWE-/FWE-T-Type according specification EI 1581 6th Edition, Category C, Type S

Aviation’s elements are fitted with a Teflon®-coated screen. Separator elements with a Teflon®-coated screen can be reused after a cleaning during coalescer element changeouts. Small areas of damage can be repaired.
