Why Choose HONGTEK PVDF Cartridge and Bag Filter Housing?

PVDF (polyvinylidene fluoride) Filter Housing is a high-performance industrial filtration equipment made of special fluoroplastics, which is famous for its excellent chemical corrosion resistance and can withstand strong acids, strong alkalis and various organic solvents for a long time. The material has a wide temperature adaptability and can work stably in extreme temperature ranges while maintaining excellent mechanical strength. With its long service life and low maintenance cost, PVDF filter housings are particularly suitable for fields such as chemical production, pharmaceutical processing and electronic manufacturing that require extremely high equipment reliability. Its excellent material properties ensure long-term stable operation under harsh working conditions.

How are PVDF Filter Housings Made?  

PVDF filter housing is made of PVDF material through integral injection molding technology. This integrated molding technology ensures the structural integrity and sealing performance of the filter housing. The main components of the PVDF filter housing include PVDF shell, PVDF top cover, fluororubber sealing ring, SS316 material ring, exhaust valve and pressure gauge, etc. Depending on the filtering requirements, the internal configuration is different. When the filter housing is installed with a filter bag, it is equipped with a PVDF filter basket. If the filter housing is installed with a filter cartridge, the filter housing is equipped with a PVDF fixing rod, a pressure plate and a nut.

What are the Types of PVDF Filter Housings?

1. PVDF Bag Filter Housing

The cylinder and cover of the PVDF bag filter housings are fixed and locked with a ring, and are suitable for filter bags Size #2. This filter is designed for highly corrosive chemical solvents, so the filter bag material must have excellent corrosion resistance, and PVDF, PTFE or PES are usually selected. PVDF possesses excellent chemical stability, withstanding corrosion from a wide range of acids, bases, and organic solvents. PTFE renowned for its exceptional inertness, resists corrosion from virtually all chemical media. PES combines excellent chemical resistance with mechanical strength. These three materials effectively ensure the long-term, stable operation of the filtration system under demanding operating conditions.

2. PVDF Cartridge Filter Housing

PVDF cartridge filter housings offer a wide range of filter element compatibility, including pleated, melt blown, and string wound filter cartridges. To meet the demands of diverse operating conditions, consumables typically utilize filter elements made of corrosion-resistant materials such as PVDF, PTFE, and PES. This series of filters currently comes in a standard 5-round, 40-inch configuration. Its housing is made of PVDF, which combines excellent chemical stability with mechanical strength, making it suitable for precision filtration in the pharmaceutical, chemical, and electronics industries. Its modular design facilitates maintenance and replacement, and its multi-cartridge parallel structure effectively improves filtration efficiency, making it an ideal choice for industrial fluid processing.

What are the Advantages of PVDF Filter Housings?

1. Strong Chemical Corrosion Resistance

PVDF filter housings are known for their excellent chemical corrosion resistance and can resist the erosion of most strong acids, strong bases and organic solvents. Whether it is high concentration of sulfuric acid, hydrochloric acid, or nitric acid with strong oxidizing properties, PVDF material can maintain stable chemical properties and will not dissolve, swell or degrade. This property makes it an ideal choice for industries such as chemical, pharmaceutical and electroplating, especially for filtering corrosive media or high-purity liquids. The inert nature of PVDF can also effectively prevent the precipitation of metal ions, ensuring the purity of the filtration process and meeting strict industrial hygiene standards.

2. Excellent Temperature Resistance

PVDF filter housings have excellent temperature resistance and can work stably in a wide temperature range. Whether in low temperature or high temperature conditions, PVDF materials can maintain good mechanical strength and dimensional stability. Its heat resistance enables it to withstand high-temperature steam sterilization and is suitable for the pharmaceutical and food industries that require frequent disinfection; at the same time, its cold resistance ensures that it will not become brittle or crack in low-temperature environments. This wide temperature adaptability enables PVDF filter housings to be used in a variety of applications from cold regions to tropical climates, providing reliable filtration guarantees for industrial processes.

3. Strong Aging Resistance

PVDF filter housings have excellent anti-aging properties and can maintain stable performance for a long time. Even under conditions of ultraviolet radiation, oxidizing environment or repeated temperature changes, PVDF material will not show obvious performance degradation. This aging resistance significantly extends the service life of the filter housing, reducing replacement frequency and maintenance costs. The stability of PVDF's molecular structure enables it to resist degradation caused by environmental factors, ensuring that the filter housing always maintains good mechanical properties and sealing effect during long-term use.

4. Excellent Sealing Performance

PVDF filter housing is made by integral injection molding technology, ensuring that the system can maintain perfect sealing under high pressure conditions. Special interface structure and high-quality sealing ring can effectively prevent medium leakage and ensure production safety. The excellent compatibility of PVDF material and sealing elements enables the filter to maintain a stable seal under various temperature conditions. This reliable sealing performance not only improves filtration efficiency but also avoids environmental pollution and material loss caused by leakage. It is particularly suitable for industrial applications that handle toxic, hazardous or high-value liquids.

5. Easy Installation and Maintenance

The PVDF filter housing adopts humanized design, making the installation and maintenance process simple and efficient. The modular structure design and standardized interface specifications make the equipment installation easy to complete without special tools. The carefully designed lifting ring fixing structure makes filter element or filter bag replacement easy and quick, significantly reducing downtime. The smooth surface of PVDF material is not easy to adhere to contaminants, making it very easy to clean and maintain. These features significantly reduce operating costs and improve work efficiency.
