Pureflo Super Melt Blown Filter Cartridges

Super Melt Blown Filter manufacturing process combines a superior process control to provide a high degree of fibre thermal bonding, without use of binders to produce a rigid, coreless filter structure.

The all Polypropylene Pureflo Super Melt blown Filter Cartridges are manufactured with a gradual porosity design whereby the fibres at the outer layer of the cartridge is more open but it is gradually bonded tighter towards the inner core of the cartridge. The effect is to retain particles at several level of the cartridge, depending on their size to avoid a premature plugging of the outer surface area by large particles and gels and promote fuller utilization of the depth matrix, resulting in an extended cartridge life against ordinary filter cartridges.

All fibres in this gradual porosity design are polymerized to bond into producing a rigid, self-supporting structure to provide consistent filtration performance under varying pressures while eliminate the need for a center supporting core. The coreless filter structure also make it an ease of disposal via incineration or shredding, without the thought of separately disposing the core.

Pureflo filters are available in ‘one-piece’ construction in various sizes between 250-1016mm and can be supplied to suit both 247mm (9 ¾”) and nominal 250mm (10”) imported cartridge housings. The one-piece construction removes the problem of by-pass which occurs when stacking 250mm long elements into vessels using spacers for sealing between each one. It also dramatically reduces down time and labour costs and in many cases, reduces potential health risks through operators having to lean over vessels that may contain liquid and gases.
