The Hydro-Carbon, series HCF, Liquid Micro Filters are specifically designed for the removal of solid particles from (aviation) gasoline, jet fuel, diesel fuel, gasoil and other light hydrocarbon products. It serves as a filter for rust particles and muck from the products, thus delivering a clean fuel into the discharge line. Due to the extended surface area offered by the synthetic pleated filter elements the lifetime is largely extended. The near absolute filtration rating safeguards the best possible cleanliness of the product. If used as pre-filter in combination with Filter/water separators the lifetime of the coalescer elements is prolonged. The product stream enters the filter housing through the inlet connection and the internally extended inlet pipe. The product stream is divided over the diameter of the filter vessel by deflection against the curved cover. The product stream proceeds to the filter elements where the solids particles are retained within the media while the product flows from outside in through the filter material. Large solid particles, retained on the surface of the filter elements, can settle on the filter-plate during low-flow or no-flow periods, extending the lifetime of the filter elements even further. After passing through the filter elements the product leaves the filter housing through the outlet connection located in the bottom of the housing.

The Hydro-Carbon, series VFWS, liquid filter/water-separators are specifically designed for the removal of free and emulsified water from (aviation) gasoline, jet fuel, diesel fuel, gas oil and other light hydrocarbon products. It also serves as a filter for rust particles and muck from the products, thus delivering a clean, dry fuel into the discharge line. It does so by coalescing the fine droplets of water found in the emulsified state and separating these from the product stream. The process of coalescing is accomplished by flowing the continuous phase of the product through a media, which has an infinite number of irregular continuous passages of very small diameters. By impingement the emulsion is broken into minute particles of water and as these particles progress through the entire depth of the media, they are coalesced into droplet size. Due to the extremely small diameter of the irregular continuous passages of the coalescing media, an accessory function of this media becomes one of filtering solid particles. As the product stream flows to the separator outlet, the droplets of water which leave the coalescing media are removed by two methods. One is by utilising the common force of gravity and the coalesced droplets are deposited into the water sump. Furthermore the product stream flows through a separator stage. The separator is provided with a hydrophobic membrane to repel the very fine droplets of water. This second stage media used for repelling droplets of water, also functions as a very efficient back-up or secondary filter element, thereby giving double protection against the transfer of solid contaminant through the separator/filter unit.
