Polypropylene Bag Filter Housings
Polypropylene bag filter housings are available in size 1 and 2 for applications where materials such as stainless steel are incompatible with the fluid to be processed.
The Polypropylene series is a side entry, recessed basket design filter housing. The polypropylene restrainer basket has a high open area and holds our complete range of filter bags, including our moulded ‘Welseal’ collar.
An important feature of our design is that it has a bolted lid, which is advantageous compared to screwed lid models. Polypropylene threads can wear over time due to repeated opening and closing of a screwed lid, which ultimately damages the lid closure arrangement. Furthermore, polypropylene can deform when repeatedly pressurized, which can also damage such closure systems. The bolted lid design enables our polypropylene filter bag housings to be CE Marked.
