Filter for reducing oil content of
compressed air
Permanent and reliable reduction of the residual oil content is one of the biggest challenges in compressed air treatment: achieved using a new generation of activated carbon adsorbers, Clearpoint V
The permanent and reliable reduction of the residual oil content represents one of the biggest challenges in compressed air treatment A new generation of activated carbon adsorbers now promises filter lifetimes up to ten times longer together with much better process reliability and reduced oil residues compared with conventional activated carbon filters

Caring for your Bekomat condensate drain
It is widely accepted that the Bekomat condensate drain from Beko Technologies is the world's most reliable condensate drain: so why do you need 'Beko Service Direct' to look after it?
The filtration system developed and marketed by compressed air specialist Beko Technologies uses activated carbon cartridges instead of the usual filter elements.
In contrast to filter elements with just a few layers of activated carbon cloth, the "Clearpoint V" cartridge is filled completely with activated carbon.
The amount of activated carbon in the Beko cartridge is twenty times as much as in the normal filter element types.

Oil vapour adsorption in compressed air systems
Constant dripping hollows out a stone, and this is a saying that certainly applies to the process reliability and the profit calculations of compressed air systems
As the compressed air flows through the cartridge, it continually moves across activated carbon.
The contact time of air and activated carbon is considerably longer than in a filter.
If a super fine filter with an outlet aerosol concentration of 0.01 mg/m3 is installed upstream of the Clearpoint V, the total residue oil content (vapour and aerosol) sinks down to 0.001 mg/m3 - three times less as with activated carbon filters.
This increase in contact time is also a great gain in terms of process reliability: for instance, during start-up of the compressor with a lower pressure network, when the flow velocities are extremely high and when the necessary contact time can only be guaranteed by a deeper filter bed.
As a result of the generous quantity of activated carbon in the cartridge, the lifetime of the filter is prolonged to an impressive extent.
While the usual filter elements "break through" ie show a marked deterioration in filter performance, after approximately 250 operating hours, this new filter cartridge can have a service life of around 2500 hours, according to the calculations of the Beko engineers.
A tenfold increase of the usual lifetime.
In order to obtain a neutral assessment in accordance with the ISO- standard of these new activated carbon adsorbers, Beko asked the Institute of Energy and Environmental Technology for an independent review of the filter lifetime and efficiency.
All the values have been confirmed.
The new Beko activated carbon adsorbers are currently supplied in three sizes, for filtering 50, 100 and 200 m3 of compressed air per hour.
An oil check indicator, available as an option, can be mounted on top of the filter to allow easy visual monitoring of the filter efficiency. Request a free brochure from Beko Technologies ...
