The high-temperature-resistant and high-efficiency air filter remains a partitioned structure, fabricated with high-temperature-resistant fiberglass or ultrafine glass fiber filter paper, aluminum foil partitions, stainless steel frames, and specially formulated high-temperature-resistant sealant. Each unit undergoes rigorous testing and is primarily used in equipment and systems requiring high-temperature air purification, such as ultra-clean ovens, ultra-clean cleaning machines, and within the chemical industry.

The 250°C high-temperature high-efficiency air filter and 260°C high-temperature-resistant air filter share the same construction methodology, utilizing fiberglass or ultrafine glass fiber filter paper, aluminum foil partitions, stainless steel frames, and specially formulated high-temperature-resistant sealant. The filter media is pleated at 180° on both sides, forming a wedge-shaped pleat layer. The pleating process leaves two creases, resulting in a wedge-shaped box pleat at the end of the partition, which helps prevent filter paper damage.

An Air Filter refers to an air filtration device commonly used in clean workshops, clean factories, clean operating rooms, laboratories, and clean rooms, or for dust prevention in electronic, mechanical, and communication equipment. There are five types of filters: coarse-efficiency, medium-efficiency, high-medium-efficiency, sub-high-efficiency, and high-efficiency filters, each with different standards and operational efficiencies.

The practical construction of high-temperature-resistant and high-efficiency air filters involves fiberglass or ultrafine glass fiber filter paper, aluminum foil partitions, stainless steel frames, and specially formulated high-temperature-resistant sealant. The filter media is pleated at 180° on both sides, creating a wedge-shaped pleat layer with two creases during the bending process. This results in a wedge-shaped box pleat at the partition's end, which safeguards against filter paper damage.

Process Characteristics of the 250°C High-Temperature High-Efficiency Air Filter:

• The unique border design of the 1.5-2.00mm stainless steel frame enhances overall structural strength.
• The rounded corrugated grooves of the 0.03mm aluminum foil partitions not only protect the filter paper from damage but also ensure even airflow with reduced resistance.
• High-quality glass fiber filter paper with a 4mm spacing increases filtration area, providing high dust holding capacity, low resistance, and high filtration efficiency.
• The single-component adhesive is suitable for long-term use at 260°C, and the temperature-resistant sealing strip at the notch prevents leakage.
• Glass fiber filter media and special high-temperature-resistant sealant gaskets are used for sealing.
