Based on different functions and structures, box filters can be categorized into various types such as medium-efficiency box filters, V-shaped high-airflow box filters, and high-temperature box filters, which are widely used in air filtration, liquid filtration, and other fields. Air filtration applications: Central air conditioning and centralized ventilation systems: Medium-efficiency box filters are suitable for central air conditioning and centralized ventilation systems. They can serve as pre-filters for high-efficiency filters, removing dust, particulate matter, and other contaminants from the air, thereby improving air quality and ensuring the normal operation of the system. Industries such as electronics and precision instruments: Industries like electronics, precision machinery, and instrumentation have high requirements for air quality. Box filters can filter out tiny ...

The paint mist filter box is a specialized filtering device designed to handle paint mist. Structure and Principle: Typically, it is made of environmentally friendly cardboard boxes combined with materials such as 3D synthetic paint mist cotton. Some boxes are crafted from corrugated cardboard that has undergone flame retardant treatment. The interior features a honeycomb-like layered structure. When the mixed air containing paint mist passes through the filter of the cardboard box, the paint mist is adsorbed onto the cardboard due to inertia and centrifugal force, thus achieving the separation of air and paint mist. The filtration efficiency for paint mist above 10 microns can reach 99.8%. Some products can achieve 100% filtration efficiency for particles below 10 microns that can cause significant surface defects. Advantages: It boasts advantages such as simple installation...

High-efficiency filters are primarily used to capture particulate dust and various suspended matter below 0.5 micrometers, serving as the final filtration stage in various filtration systems. Structure and Materials: It utilizes ultra-fine glass fiber paper as the filter material, with materials such as adhesive board paper and aluminum foil folded to form the divider plate. It is sealed with a new type of polyurethane sealant and constructed with galvanized steel plates, stainless steel plates, and aluminum alloy profiles as the outer frame. Types: According to structural forms, they can be divided into high-efficiency filters with partitions, high-efficiency filters without partitions, high-flow rate high-efficiency filters, ultra-high-efficiency filters, etc. In addition, there are special types such as ultra-high-efficiency filters, antibacterial high-efficiency air filters w...

Chemical filter is a new type of air purification equipment for treating malodorous, toxic and corrosive gases in the air. Working principle: air is purified mainly by physical adsorption and chemical reaction. Physical adsorption relies on the microporous structure of adsorption materials such as activated carbon, and adsorbs pollutant molecules through van der Waals force. Chemical adsorption means that activated carbon and other filter materials are impregnated with chemical reagents, which react with acidic or alkaline gases to convert them into harmless substances. Some filter materials can also catalyze the decomposition of harmful gases such as ozone and hydrogen sulfide by adding catalysts. Product features: the filter material is often designed with filter core lock cap, which has good sealing performance, and the filter cartridge can be free of metal contact. Usually ma...

Bag filter is a multi-purpose filtering equipment with novel structure, simple operation and strong adaptability. It can be used for liquid filtration and air filtration, and is widely used in many fields.   Liquid filtration application Chemical industry: it can filter the particulate impurities in coatings, resins and solvents, and protect the reaction kettle or spraying equipment. At the same time, it can also be used to purify acid/alkali liquor, but it needs to be made of corrosion-resistant filter bag materials such as polypropylene or PTFE. Food and beverage industry: it is often used for clarifying and filtering syrup, fruit juice and beer to remove suspended solids and microorganisms, and can also be used for intercepting impurities in edible oil refining. Pharmaceutical industry: it can be used for terminal filtration of raw materials and water for injection to ...

Plate filter is a common filtering equipment, which has two types: air filtration and solid-liquid separation. This paper mainly introduces air filtration: Plate air filter Structure composition: mainly composed of frame and filter element. Frames are usually made of metal materials, such as galvanized steel plates, and some are made of waterproof cardboard, which is firm or light. The filter element generally adopts polyester synthetic fiber, non-woven fabric and synthetic glass fiber as the filter material. Working principle: Depending on the pressure difference caused by air flow, air passes through the filter material, and pollutants such as large particles of dust, hair and fiber in the air are intercepted by the filter material, thus achieving the purpose of air filtration and purification. Characteristic Advantages: compact structure, light weight and convenient installa...
