Chemical plants, petroleum refining, high-temperature dust collection and polymer melt filtration have always been the hard cases in the filtration industry. Conventional PTFE and synthetic fibre media, once exposed to high temperature, acids, alkalis or organic solvents, age, swell and tear apart. The filtration rating drifts off spec and the risk of product contamination rises. To hold their filtration accuracy, many plants have no choice but to shorten the replacement interval — and continuous production becomes very hard to guarantee.
Sintered stainless steel fibre felt elements are engineered for exactly this kind of harsh duty: they withstand a working temperature of up to 480 °C in long-term service and resist attack from acids, alkalis, oils and organic solvents, so the media itself is not consumed by the process fluid.
Our SJZ series sintered stainless steel fibre felt covers a filtration rating range of 2 μm to 60 μm, with high porosity and excellent dirt-holding capacity, so the differential pressure climbs slowly. The material has good permeability and low pressure loss, meaning media resistance never drags down the flow of The weakness of ordinary filter media is simply insufficient temperature and chemical resistance. the whole system. Being metal, it welds and forms easily and can be produced as pleated cartridges, disc filters, filter plates and other configurations, with heavy-duty and mesh-protected versions available on request.
It fits vacuum pump protection filters, fuel filtration, automotive airbag filters and prefiltration ahead of ultrafiltration systems. What it offers is not only stable filtration accuracy but repeated cleaning and regeneration — it is not a single-use consumable. Feedback from many chemical customers is that after switching to sintered felt, element replacement frequency dropped by more than 70%, and contamination problems in the process medium improved markedly.
If your filtration system runs continuously in a high-temperature environment with corrosive media, and ordinary filter media keeps failing, sintered stainless steel fibre felt is a stable and dependable long-term filtration solution. Our factory produces to your requirements, delivers on schedule, and stands behind the quality.
