High-temperature resistant air filters are specialized filtration equipment designed to filter particulate matter and impurities in the air under high-temperature conditions. Their core feature is the ability to maintain stable filtration performance and structural integrity at relatively high temperatures (typically ≥ 80°C, and some models can withstand temperatures above 200°C or even higher). They have a wide range of applications, mainly in scenarios where high-temperature operations are required and strict air quality standards are imposed. The specific applications are as follows:
1. Industrial production sector
High-temperature drying / baking processes
Food processing: such as drying lines for biscuits, instant noodles, and meat, which need to filter dust in the hot air to prevent product contamination.
Painting industry: high-temperature curing ovens (such as the drying stage of automotive painting lines), filtering the air entering the oven to prevent dust from adhering to the coating surface and causing defects.
Material processing: high-temperature shaping or drying processes for plastics, rubber, and composite materials, to avoid impurities in the air affecting material properties.
II. Energy and Chemical Production
Boilers and Generator Sets: Filter the high-temperature combustion air entering the boiler to reduce the wear on the furnace and heat exchangers caused by dust, and improve combustion efficiency.
Chemical Reaction Vessels: Some high-temperature chemical reactions require the introduction of clean air. High-temperature resistant filters can prevent impurities from interfering with the reaction process or contaminating the products.
III. Medical and Laboratory Fields
High-temperature Sterilization Environment: For example, hospital high-temperature steam sterilizers and laboratory dry heat sterilization ovens. During the cooling stage of the equipment, the air introduced needs to be filtered through high-temperature resistant filters to prevent external microorganisms or dust from entering the sterilized items (such as medical devices, laboratory equipment).
Biological Safety Laboratories: Some experimental sections involving high-temperature inactivation require high-temperature resistant filters to treat the contaminated high-temperature air, to prevent the spread of harmful microorganisms.
