Filter Element
The units are fitted with multiple elements to suit the process requirements and are
securely fastened inside the vessel.
The filter support/housings are 2mm perforated mild steel zinc passivated double/triple
length double walled, each with 1-2 micron “Pafic” elements (Designed especially for and
used by British gas in the UK and worldwide).
The elements are designed to offer an economical solution to the fine filtration of gas by
utilizing disposable 1 – 2 μm Phenolic resin bonded fibre glass sleeves and cleanable
reuseable element support/housing. The fibre glass sleeve is 8mm thick and offers a high
volume of voids within the fibres capable of retaining large quantities of contaminate before
blockage occurs. The flow through the elements is depth type from inside to out thereby
trapping all contaminant within the element wall. Upon withdrawal any loose contaminant
will remain within the support/housing and not fall back into the filter vessel resulting in
cleaner and easier maintenance.
The element support/housings are manufactured from robust perforated zinc plated mild
steel sheet and are capable of withstanding high differential pressures and flow reversals.
