• High efficiency, low resistance, large dust holding capacity

  This filter adopts ultra-fine glass fiber filter paper as the filter material, together with aluminum foil spacer and stainless steel or galvanized outer frame, as well as special high-temperature-resistant sealant, making it possible to achieve a very high level of filtration efficiency while maintaining low resistance, thus allowing more air volume to pass through and a larger dust holding capacity.

• High Temperature Resistance

  The high temperature resistant high efficiency filter with partition can be used for a long time in an environment as high as 280℃, which makes it very suitable for air purification in high temperature environments, such as ultra-clean ovens, UV ovens, tunnel ovens and other equipment.

• Long service life

  The service life of high-temperature resistant HEPA filters is closely related to its material, structure and working conditions. The selection of suitable materials and excellent manufacturing process, coupled with good maintenance, can significantly extend its service life and thus reduce the cost of use.

Application Scenario

• High temperature drying equipment such as ovens and drying equipment such as ovens.

• High-temperature sterilization equipment, such as the use in the pharmaceutical industry.

• Terminal filtration of air conditioning and ventilation systems with high cleanliness requirements.

• Other places requiring fire protection and high ventilation temperatures.

Preparation before use

• Confirm that the model and specifications of the filter meet the requirements for use.

• According to the manufacturer's instructions, perform appropriate heating and cooling treatment on new filters to ensure that the sealant is fully cured.

• Check the filter for any damage or defects to ensure that it is intact at the time of installation.

Installation and Maintenance

• Installation: Install the filter correctly according to the guidelines provided by the manufacturer, pay attention to the arrow markings on the filter to ensure that the airflow direction is correct.

• Maintenance: Regularly check the pressure drop and airflow of the filter, and replace the filter in time if necessary.

• Cleaning: For washable filters, clean and reinstall them according to the specified methods.

Design Features

• Filtration efficiency: the filter can effectively filter airborne suspended particles above 0.3μm, and the efficiency level is usually H13 or H14 grade, ensuring the cleanliness of the air.

• Temperature resistance: high temperature resistant design, can work in 250℃ to 350℃ environment for a long time, some can even withstand temperatures up to 400℃ to meet the needs of different high temperature environments.

• Structural design: Adopting a structure with a partition, which is usually made of aluminum foil or stainless steel, helps to maintain the stability of the filter media and reduce the resistance, and at the same time enhances the strength of the overall structure.

• Sealing performance: Special high temperature resistant sealant and sealing gaskets are used to ensure the sealing of the filter under high temperature and avoid leakage.

• Dust holding capacity and resistance: A large dust holding capacity and low initial resistance ensure a long service life and stable filtration effect.

Material Selection

• Filter Media: Usually adopts high temperature resistant ultra-fine glass fiber filter paper, which has good filtration efficiency and sufficient strength to withstand the influence of high temperature environment.

• Partition: made of aluminum foil or stainless steel, which can maintain proper spacing between the filter materials and withstand high temperature without deformation.

• Frame: mostly made of stainless steel or galvanized steel to ensure a strong and durable structure.

• Sealant: High temperature resistant special sealant is used to ensure good sealing performance even under high temperature conditions.

Performance Parameters

• External dimensions: According to different application scenarios, the external dimensions of the filter will change to meet the needs of the installation space.

• Rated air volume: It refers to the air flow rate that the filter can handle per unit of time, reflecting the handling capacity of the filter.

• Initial resistance and final resistance: indicate the resistance of the filter in the old and new state respectively, reflecting the performance change of the filter in the process of long-term use.

• Filtration efficiency: the percentage of filtration efficiency of the filter on particles of specific particle size under specified test conditions.
