Filter elements, renowned for their exceptional high and low-temperature resistance, chemical stability, excellent electrical insulation properties, non-adhesiveness, weather resistance, flame retardancy, and good self-lubricating capabilities, have found wide applications in industries such as chemical, petrochemical, textile, electronics, electrical, medical, and mechanical fields. Typical uses include:
1. Food: Sterilized exhaust filtration for fermentation tanks, storage tanks, and ingredient tanks.
2. Solvent sterilization filtration
3. Steam, compressed air, and catalyst-based sterilization filtration
4. High-purity gas filtration for the electronics industry
5. Steam Filtration
6. Security Filtration for Water and Industry
7. Security filtration for ultra-filtration, RO, and EDI water treatment systems, post-odour sterilization filtration, and ozone aeration.
PTFE Sintered Filter Cartridge Precautions
1. Not suitable for filtration of halogenated hydrocarbons, aromatic hydrocarbons, or gasoline.
2. Operating Temperature:☆General Type: <50℃ (Pressure Difference: 0.3MPa)
High-Temperature Type: <100℃ (Pressure Difference: 0.2MPa)
121℃ steam sterilization, 30 minutes per cycle, up to 7 cycles.
3. Withstanding a large pressure difference (at 25°C): Forward: 0.42 MPa
Reversed: 0.21 MPa
With increased operating temperature, the tolerance for pressure difference is relatively reduced.
4. Applicable pH Range: 1-14
5. Filter elements are consumables; however, during cleaning and disassembly, care should be taken to avoid scratching, bumping, dropping, or other damage. Prevent人为 damage by strictly not applying force to the surface of the filter element with tools.
6. Gradually increase the pressure to the required working pressure during filtration, strictly prohibit rapidly opening the valve to boost pressure instantly.
7. During backblowing and backwashing, the filter element is typically pre-backblown with pure gas, at a pressure 1.2-1.5 times the working pressure, for 3-5 seconds each time. Repeat this process 4-6 times, then proceed with backwashing using clean liquid for 3-5 minutes, performing this operation 2-3 times.
8. If the pressure loss remains significant after the filter element is online backblowing and backwashing, it should be promptly removed for cleaning.
