The Vokes Filter Coalescer is a static device for the removal of solids and free water from Distillate and Light Liquid Fuels and Mineral Lubricating Oils.
The cartridge combines a long life depth type pre-filter media designed to give extended life by the removal of pipe scale, rust, waxes and asphaltenes that would otherwise cause the coalescent media to blind.
The pre-filter, together with the first and second stage coalescing medias effectively combine small droplets of water into large droplets which are then separated from the oil flow by gravity.
A final stripper screen is fitted to further minimise any risk of carry over of small droplets into the clean oil discharge.
The purified oil is discharged at the top of the housing, while the water is drained from the bottom.
Principal of Operation
The small droplets of water are intercepted by fibres and because of the hydrophilic nature of the fibres, are retained. As the number of droplets collected increases they join together to form a layer of water.
The flow of the oil then pushes this water through the media to the outside where it forms large droplets on the sock surrounding the cartridge.
These droplets then grow until they reach a size which causes them to fall off and drop to the bottom of the housing through gravity.

Applications
MANN+HUMMEL filters for compressed air systems ensure consistent performance of compressed air systems and systems installed downstream. They help to maximise the service life of all filters in the system.
Advantages
The advantages are
low oil and energy consumption
low wear in the compressed air system
custom-made solutions
different designs: air/oil separators, air-oil separator boxes, deep-bed filters, air/oil separators for vacuum pumps

Vokes' Microfelt cartridges are designed for the fine filtration of fuel and lubricating oils, along with other fluids including hydraulic oils and glycol. Manufactured from a range of specially selected synthetic felt media, Vokes Microfelt cartridges have excellent depth filtration characteristics and a high dirt holding capacity. Cartridge integrity and filtration performance relies on design features which include welded media seams, filter media bonded to the end caps and the fitting of leak proof seals. Manufactured to high quality control standards, all filter media is batch tested for filtration performance and metal components deburred.
Vokes Microfelt cartridges are available in 10 standard sizes and can be used in multiple cartridge vessels with flow rates typically up to 300m³/h in lubricating oil systems. There are four basic specifications including cartridges capable of withstanding high collapse pressures, high temperatures and chemically aggressive contaminants. Vokes Microfelt cartridges are disposable, ensuring that all collected contaminants are removed from the system when the cartridges are renewed.
