SUS316L SS304 Stainless Steel air vent filter for water tank

Product Overview

A Stainless Steel air vent filter is an efficient filtration device designed specifically for gas exchange in storage tanks. Its main function is to prevent the tank from being contaminated by bacteria or dust in the atmosphere during the process of air discharge and suction. This type of filter is widely used in the pharmaceutical industry and food industry to ensure that the storage tank can achieve sterilization when replenishing gas, in compliance with GMP and sterile hygiene requirements.

This product adopts stainless steel material and microporous membrane folding filter element, which can effectively filter particles, bacteria and viruses in gas, ensuring gas purity. Respiratory filters not only solve the problem of bacterial contamination in the air, but also improve the quality of disinfection and sterilization, making them important equipment for ensuring the safety of the production process.

Production process of air vent filter housing

The production of single card breathing filters follows strict quality control standards, and the main process flow includes:

• Injection molding: Plastic parts such as the upper and lower covers are processed and molded by injection molding machines to ensure precise dimensions and smooth surfaces without burrs.
• Filter preparation: Process the filter material (such as polypropylene) into a foldable filter membrane structure, which is carried out in the purification workshop to avoid contamination.
• Automated Assembly: Using automated production lines , including vibration discs, feeding belts, electric push rods, and pneumatic cylinders, to achieve automatic assembly of upper and lower covers and filter elements. Some advanced production lines are also equipped with auxiliary clamping devices and feeding devices to improve assembly efficiency and consistency.
• Sealed connection: Key processes such as ultrasonic welding are used to ensure the tightness of the shell, and some products adopt mechanical buckle design to simplify assembly.
• Sterilization packaging: The product has been sterilized with ethylene oxide and sealed in a single package under sterile conditions. The packaging needs to undergo tests such as vacuum leak, leakage, and bacterial resistance to ensure that the product remains sterile during its shelf life.
• Quality Inspection: Conduct comprehensive testing on finished products, including appearance, shell sealing, filtration rate, gas resistance, sterility testing, and residual ethylene oxide content. Only products that meet the standards can be shipped.

Advantages of the air vent filter housing

• Efficient filtration performance: Using precision filter membranes, the filtration efficiency of 0.02 μ m particles is high, with a bacterial filtration rate of up to 99.99% and a virus filtration rate of over 99.9%, effectively preventing cross infection in gas exchange.
• Wide applicability: Can withstand high temperature and high pressure environments, suitable for filtering various gases (including air, inert gases, and even sterilization steam), and meet the special needs of different industries.
• Compliant with industry standards: Designed and manufactured strictly in accordance with GMP standards, meeting the stringent requirements for sterile environments in industries such as pharmaceuticals and food.
• Easy maintenance: Some products adopt automatic peeling system and intelligent control system , which can automatically monitor the pressure difference and start the cleaning program, reducing the need for manual maintenance.

Maintenance and Usage Guide

• Daily inspection: Regularly check the working status of the filter and pay attention to observing changes in pressure difference. If the filter is found to have increased resistance due to excessive dust accumulation, it should be cleaned or replaced in a timely manner.
• Cleaning and Disinfection: The respirator should be thoroughly cleaned and disinfected before use. Follow the manufacturer's recommended methods and cycles during cleaning to avoid damaging the filter elements.
• Filter cartridge replacement: When the filtration efficiency significantly decreases or reaches the recommended service life, the filter cartridge should be replaced in a timely manner. The replacement operation should be carried out by professionals according to the regulations.
• System Inspection: Regularly inspect relevant electrical components and connecting circuits to confirm that there is no damage, aging, or short circuit, ensuring the safe operation of the system. - Safety precautions : It is strictly prohibited to store flammable and explosive materials in respirators or adjacent containers; Follow the operating procedures in the product manual to ensure safe use.
