Coalescer Element I-656C5TB


Ref.All4Jet : PC214-00094

Previous.ref : PC214-00094

Ref.maker : I-656C5TB

The I-656C5TB Velcon coalescer cartridge is designed to separate dispersed emulsified water particles and contaminants from aviation fuel.

Coalescer cartridges are used during the first stage of filtration/separation of hydrocarbon fluids. They collect emulsified and highly dispersed water particles into larger droplets and filter out particulate contaminants.

Coalescing cartridges are mainly used to coalesce emulsified water and remove particles from hydrocarbon fluids. The most important application is the filtration of aviation paraffin.

Velcon coalescing elements are available with a threaded base or open ends and with fibreglass or a combination of fibreglass and pleated media.

Threaded base coalescing cartridges are recommended for most applications. They simplify installation and replacement by eliminating the need for cover plates, centre plates, nuts, washers and seals. They are intended for use in Velcon and other filter/separators. Threaded base adaptors are available to convert containers currently using open ended elements.

Open-end coalescers are offered with a one-piece construction that reduces the number of seals and improves overall reliability.

Glass fibre coalescers combine deep particle filtration with a deep coalescing structure. These models have progressively thinner layers to achieve deep particle filtration.

Combined glass fibre and pleated media coalescers remove particles primarily in the high surface pleated core. They comprise one or more layers of pleated media within a cylinder of moulded fibreglass laminates to provide an extended surface area for particle filtration. Pleat corrugation and separation materials are used to keep the pleats open for full use.
