Meltspun materials

The meltspun materials are usually formed into thin sheets, like paper or cardboard, and are then widely used in pleated form, as cartridges, shown typically in Figure 2.4. These media are capable of exceedingly fine degrees of filtration, and a great deal of microfiltration is now undertaken with them.

Filter medium material for the removal of viable organisms from compressed air tends to be either of borosilicate glass microfibres or meltspun fleece or PTFE membranes, supported on 100% glass fibre woven fabric or polysulphone or polypropylene spunbonded textiles.
