EFS C. Type Pulse Clean Units EFS C. Type Pulse Clean Units

EFS C. Type Pulse Clean Units

The EFS C pulse jet cleaning, free standing cartridge unit has been designed for use in a dust control applications where a compact, high efficient dust control unit that is required to operate continuously over long periods of time is required.

The EFS C pulse jet unit utilises automatic constant pneumatic cleaning of the cartridges which allows the unit to be operational for long lengths of time without the need to stop the system for clean down of the filter media.

The cartridges used by EFS are of a single open ended type therefore there is only one seal required on the open ended dust end. Due to the high levels of filtration that can be achieved by the use of cartridges this allows for a more compact unit design that requires less floor space, but can still achieve high filtration levels .Cleaning of the cartridge elements is carried out by means of compressed air injection from the clean air side, this reverses the normal flow of air through the cartridge element, with the passage of air dislodging the dust held on the cartridge which drops into the collection bin. Cleaning of the elements takes place on a continuous basis with a run-on-timer fitted as standard.   

The EFS C standard units are built in three different configurations 2, 3 and 4 high with a maximum total of 24 cartridges being employed in the 4 high configurations, the range of EFS C come in two basic designs either with an integral fan set or without.

Quick release bins are provided at the hopper section, however alternative hopper designs can be accommodated if required eg: hoppers with bagging off facilities or single waste discharge outlet hopper with rotary valve.

 Reverse jet filter (Sock type) V Range

The EFS V Range of filter units consist of a number of tubular filter elements mounted on wire mesh support cages, they are held vertical in the filter section of the unit, the dust ‘cake’ is then cleaned from the filter elements by compressed air which is injected into the centre of the filter tubes on the clean air side causing a shock wave effect which dislodges the built-up dust and allows it to fall freely into the collection hopper below.

The EFS V ranges of filter units have been designed for heavy dust loadings or where the application demands continuous use over extended periods.

The EFS V range is available in three basic width variations from 8, 10 and 12 filters per row, with filter sock lengths from 1.0m through to 4.0m

The EFS F Range are a fully self-contained range of  ‘Pulse jet’ filter units supplied complete with a hopper section if required. The filter body section is flanged which allows for mounting the EFS F type unit in different orientations. These units can be fitted with integrated fan sets to enable them to be utilized in small localized applications.

Without a fan set, these units can be used as a vent type unit, which can be fitted on silos or vessels that require venting whilst being filled.

There are no moving parts within the EFS F venting unit which minimised maintenance requirements.

The EFS F is capable of handling heavy dust loads at high filtration velocities at a constant level of resistance, with a collection efficiency of

99.9% Should you require further details of this type of unit please contact one of our sales engineers to arrange a site visit.
