About this file
This is a product specification document for the AstroCel® III High Efficiency Particulate Air (HEPA) filter manufactured by AAF Flanders. The filter is designed for applications requiring high airflow capacity up to 600 FPM with ultra-low pressure drop, including semiconductor and electronics manufacturing, pharmaceutical processing, photo film manufacturing, hospitals and laboratories, and food processing facilities. Key performance specifications include a rated airflow capacity of 2400 CFM at 1 inch water gauge initial resistance, 436 square feet of media area in the standard 24" x 24" x 11½" gasket seal model, and 99.99% efficiency at 0.3 micron. The filter features multiple mini-pleat media packs assembled in V-bank configuration to provide longer service life, lower energy consumption, and reduced operating costs compared to conventional HEPA filters.
The AstroCel III is available in both gasket seal and gel seal frame options for installation in high-integrity filter holding frames, side access housings, and bag-in/bag-out systems. Additional size options include 24" x 12" x 11½" (1125 CFM gasket / 1025 CFM gel) and 23⅜" x 23⅜" x 11½" (2270 CFM gasket). The filter utilizes an extruded aluminum frame with chemical-resistant anodized coating and two-component polyurethane seals to prevent bypass leakage. Each filter undergoes individual factory testing with performance data and serial number recorded, and operates at a maximum temperature of 200°F. The product is UL Classified per UL Standard 900 and ULC-S111. AAF Flanders offers a TCO Diagnostic software tool to assist in selecting optimal filter designs for specific operating conditions, with additional information and availability available through their sales team at 888.223.2003.

Longer Service Life and Lower Energy Consumption Multiple mini-pleat media packs, assembled into a series of V-banks, permit substantially more media to be contained in the filter—double the media typically found in most HEPA filters. Maximum effective media area provides greater airflow capacity, low resistance, high dust holding capacity, and unusually long service life.
The V-bank configuration provides greater airflow capacity and longer service life, while lowering operating costs.
Typical Applications AstroCel III HEPA filters are ideal for applications operating with higher airflows, up to 600 FPM, and requiring ultra low pressure drop:
| • | Semiconductor and electronics manufacturing |
| • | Pharmaceutical processing |
| • | Photo film manufacturing/processing |
| • | Hospitals, laboratories, and optical facilities |
| • | Food processing |
Designed for High Performance Media Configuration Reduces Operating Costs AstroCel III filter media is made from sub-micron glass fibers formed into a high density paper. Glass filament separators are used to form the media into mini-pleat panels that withstand high velocity airflow. The V-bank configuration optimizes media performance for high airflow at very low resistance. Mini-pleat packs are sealed to the frame with two-component polyurethane to increase rigidity and prevent bypass leakage.
Construction Extruded aluminum frame components resist chemical corrosion, provide high strength, and are lighter. Cell sides are made from a single extrusion to maximize construction integrity.

AstroCel
III
The AstroCel III High Efficiency Particulate Air (HEPA) filter is designed to meet the demanding airflow and efficiency requirements of the most critical applications.
• Longer service life – 436 square feet of media – means fewer changeouts
• Low energy consumption and lower operating costs
• High capacity operation with minimal resistance to airflow;
2400 CFM rated airflow at 1 in. w.g.
• Chemical-resistant anodized aluminum frame provides superior strength
• One piece polyurethane gasket seal and gel seal designs available
AstroCel® III filters are designed for installation into high integrity filter holding frames, side access housings, and bag in/bag out systems, including one piece urethane. Multiple gasket seal filters are available, as well as gel seal filters for frames and systems designed with knife-edge seal framing. Extractor clips are offered for side access systems requiring gel seal frames.

TCO DiagnosticSM Analysis The large media area and lower resistance of the AstroCel III filter can greatly reduce operating costs. Your local AAF Flanders sales representative uses an exclusive software tool, Total Cost of Ownership (TCO) Diagnostic, to help you choose the optimum filter design for your specific operating conditions.
Guaranteed Performance Every AstroCel III filter is individually tested before it leaves the factory—your assurance that it meets rated efficiency.
The actual test data is indicated on the label. Each filter is also assigned a serial number, and a permanent record is kept of the materials of construction and performance.
Efficiency for all models is 99.99% @ 0.3 micron.
Dimensions are actual and do not include gasket.
Additional sizes are available. Call your local AAF Flanders sales representative, 888.223.2003, for availability.
