THE WORLD LEADER IN CLEAN AIR SOLUTIONS HIGH TEMPERATURE HEPA FILTERS • High temperature resistance up to a peak of 752°F (400°C) to protect ultra clean processes • Handling high airflow rates up to 1236 CFM for critical processes S • tainless steel construction prevents potential damage from heat stretching • ses elastic fiberglass sealant U eliminating cracking or particle shedding seen with ceramic • Free of silicone to safeguard air quality The AstroCel I HTP high temperature HEPA filter from AAF is designed to provide excellent protection of high temperature processes in ultra clean environments that can be found in industries such as pharmaceutical or electronics. It supports compliance with the most stringent requirements so that the high output quality requirements can be realized at minimized failure costs. Reliable High Temperature Operation In continuous service, the AstroCel I HTP filter offers a maximum temperature resistance of 662°F (350°C), with a peak of 752°F (400°C) for one hour. The robust all stainless steel structure prevents the media damage caused by thermal stresses where materials with different expansion coefficients are used during temperature rising and falling. The elastic fiberglass media sealant is not prone to integrity breaches from stress cracks giving a superior durability. Thorough heat-cycle tests have confirmed damage-free construction and consistent performance in pressure drop and efficiency at 662°F (350°C). Bias crimped separators in combination with stabalizer bars inside the media pack ensure the uniformity of the media pack is maintained in operation. The AstroCel I HTP filter offers a unique combination of high temperature operation and superior durability, optimizing process results and limiting unscheduled downtimes. High Air Quality Conditions The AstroCel I HTP filter provides a high air quality level with a particulate collection efficiency of ≥ 99.97% for 0.3 μm particles at a nominal airflow of 1236 CFM. With this high airflow rate, ventilation can be optimized for enabling speedy temperature control. The silicone-free construction of the AstroCel I HTP filter further enhances the air purity level during the various steps of the sterilization process, without the risk of siloxane contamination. For critical process applications in which no concessions can be made to quality and yields, the new AstroCel I HTP filter from AAF provides the right solution for ensuring that the strict air cleanliness conditions are met. Beneficial Total Cost of Ownership Stainless steel structure for superior durability during heating and cooling. The features described above can allow for a significant reduction in heating and cooling times, reducing the total cycle times of batch processes, increasing production throughput and reducing overall cost. Applications Pharmaceutical: dry heat sterilization and depyrogenation Electronics: clean oven for LCD and TFT manufacturing Food and Beverage: drying facilities Chemical: cleaning and drying for laboratory research
