What Is FiltEdge's PVDF Filter Housing?
FiltEdge’s pvdf filter housing is a plastic filter housing. Its biggest advantage is that it will not produce metal ions like metal filters, when you use pvdf filter housing filtration, the whole process will not produce metal free ions, which is especially suitable for some high-end conditions, such as high-purity water, semiconductors, electronic chemicals in the pre-filter, which can protect your downstream equipment, but also improve the purity of the product.
Types of PVDF Filter Housing
The excellent chemical properties of FiltEdge’s PVDF Filter Housing are an important factor in the wide range of applications in high-end industries. We have more than a dozen styles for you to choose from. Or you can choose to customize the filter that best matches your working conditions.
We can provide 1-2 bags, top entry/side entry structure. Ensure that there will be no flange deformation or liquid leakage.
PVDF Cartridge Filter HousingAvailable in 1-7 round sizes for semiconductor and photovoltaic cleaning lines.
A filter that combines the high-pressure and high-temperature resistance of a stainless steel filter with the extreme corrosion resistance of PVDF plastic, making it a cost-effective filtration solution for demanding applications.
Advantages of PVDF Filter Housing
With the common plastics prone to deformation and leakage, and metal shells that are not resistant to strong acids and metal precipitation, FiltEdge’s PVDF Filter Housing is designed to address your industrial pain points and apply our technological strengths to ensure that your system operates stably, long-lastingly, and with zero contamination under strong corrosive conditions.
With excellent chemical compatibility with acids, alkalis, oxidizers and a wide range of solvents, PVDF Filter Housing is highly resistant to corrosion.
Never precipitate organic carbon (TOC), fluoride ions, additives, stabilizers, metal ions and other precipitates, suitable for working conditions with extremely high purity requirements.
All-plastic PVDF Filter Housing can be operated continuously at temperatures ranging from -20 to 90°C, and instantaneously at temperatures up to 120°C, providing long-lasting and stable temperature resistance.
The key parts of the main body, such as the cylinder and connectors, are 100% pure PVDF, and the non-contact parts, such as the bracket, are made of PP/PVC to ensure the purity of the process.
Adopting high performance PFA/FEP covered Viton sealing ring and precision injection molded deep dovetail groove design to eliminate the possibility of leakage.
Supports ANSI/DIN/JIS standard flange connections, high pressure Union and classic NPT/BSPT threaded connections, as well as individually designed Vent, Drain, and Differential Pressure gauge function holes to ensure smooth connections to your existing system.
PVDF Filter Housing is extremely resistant to UV and ozone degradation and will not deteriorate in mechanical strength even after years of outdoor use.
The material characteristics of PVDF Filter Housing make its inner wall surface extremely smooth, which is not easy to harbor bacteria and difficult to scale, and is suitable for pharmaceuticals, ultrapure water, and viscous liquids.

From the whole process to provide you with heart-saving and cost-saving services and equipment, and also let you have protection later.
Why Choose FiltEdge's PVDF Filter Housing?
FiltEdge’s PVDF Filter Housing can provide you with solutions to industrial problems such as the medium is too corrosive, ordinary PP or metal housing is not stable enough; precipitation and contamination; seal leakage, incomplete drainage, and so on.
PP filters are easy to oxidize and become brittle when facing high concentration of nitric acid and chromic acid; stainless steel filters are easy to pitting and perforation when encountering hydrofluoric acid or high concentration of chlorine ions; FiltEdge’s PVDF Filter Housing can maintain the absolute stability of the molecular structure when filtering strong acids, alkalis, oxidants or highly toxic solvents. This eliminates corrosion-induced bulging and perforation at the source, preventing long downtime and economic losses.
In wafer fabrication or high-purity pharmaceutical processes, where metal precipitation at the ppb level and traces of organic carbon can lead to product contamination, FiltEdge guarantees that you will receive a high quality, 100% all-plastic PVDF Filter Housing, with no metal content throughout the entire structure. Even in ultra-pure water or strong acid conditions, there will be no slagging, leaching, or ionic contamination, increasing your product’s yield.
In the production process, the most afraid of spraying, especially strong corrosive liquids, FiltEdge’s PVDF Filter Housing adopts precision injection molding “dovetail groove anti-migration” design, together with PFA/FEP coated rigid and flexible integrated perfluorocarbon seals, in the alternation of heat and cold, the resilience is still durable, to ensure that the PVDF Filter Housing will not be affected by any leakage. This ensures the sealing of the PVDF Filter Housing and protects your personal safety and production safety.
When replacing filter bags/cartridges, workers are afraid of the acidic and alkaline liquid residue on the bottom of the PVDF Filter Housing, which will not only cause chemical pollution, but also personal injury. Our PVDF Filter Housings are available with either a tilted guide base or a fluted tilting base design with a full low level drain port. All you need to do before changing consumables is to open the drain valve, and the chemical liquids will be drained away by gravity, keeping your production safe.
