High Capacity AstroCel® I HCX filters are designed to handle higher airflow than a standard HEPA filter. This offers greater operating flexibility and cost savings. Double the airflow of a standard capacity only a 40 % increase in resistance. Lower resistance, lower energy cost, and longer life at the same rate of flow.

AstroCel® Selection	N/A AstroCel® I filters are available in a wide variety of standard sizes and construction materials. Special sizes can be fabricated or special materials used for unique requirements. There are twelve criteria encompassing materials and performance that go into the makeup of an AstroCel® I filter. Careful selection of the right combination will result in the filter that best meets the needs of your application.

High Temperature AstroCel® I Filters	N/A AstroCel® I filters are constructed with stainless steel or aluminum cell sides and are available for applications with continuous operating temperatures up to 750 ºF. 400 ºF (204 ºC) - Stainless Steel or Aluminum Cell Sides, White RVT Silicone Board 500 ºF (260 ºC) - Stainless Steel or Aluminum Cell Sides, Red RVT Silicone Board 750 ºF (399 ºC) - Stainless Steel or Aluminum Cell Sides, Black Cement Bond
Special Construction AstroCel® I Filters	N/A AstroCel® I Side Access Filters AstroCel® I filters are constructed with a flange at the top and bottom for installation into earlier models of AstroSeal® side access housings. The filters are available with wood or metal cell sides. Military and Nuclear Designs AstroCel® I filters are available to comply with military and nuclear specifications (ASME AG-1) requiring special cell side material, radiation resistant media, rabbeted joints, special testing, and special packaging and marking.
Leak Scan Testing	N/A Filters that pass the overall efficiency test may still have minute pinhole leaks. AstroCel® I filters can be factory scanned to ensure there are no pinhole leaks. Scanning detects these leaks, which are repaired before the filter is released for shipment. AAF Flanders® uses a proprietary static scan test with a challenge aerosol of non-toxic, poly functional alcohol that leaves no residue on the media. For pharmaceutical and those applications requiring PAO, AAF Flanders® offers scanning with this material using a light scattering photometer.

Overall Efficiency Testing	N/A Two methods of overall efficiency testing used: PAO Test - This has been the industry standard for many years. It is conducted using a light scattering photometer. The filter is challenged with Polyalphaolefin (PAO). By measuring the upstream and downstream concentration, filter efficiency can be calculated. Laser Test - The filter is tested with a laser spectrometer using polystyrene latex (PSL) spheres. Filter efficiency is determined by comparing the upstream and downstream concentrations. Efficiencies down to 0.10 micrometers can be determined
Media Testing to Meet Exacting Quality Standards	N/A Every roll of media is carefully checked for a specific set of physical and performance characteristics, including: Efficiency Thickness Tensile Strength Water Repellency Resistance Weight Binder Content
Underwriters Laboratories Classification	N/A UL Classified AstroCel® I and AstroCel® I HCX filters are UL Classified. Testing is performed according to UL Standard 900 and ULC S111 (except those made with non-fire-retardant wood cell sides). UL 586 This standard ensures that each filter is individually tested at the factory, Additionally, representative filters are tested by UL to ensure that they provide HEPA level filtration, after being subjected to the following conditions: High moisture (90 % R.H) High temperature (700 ºF / 371 ºC) (short duration) Low temperature (27 ºF to -3 ºC) UL also subjects the filter to a spot flame test (1750 ºF/954 ºC) A numbered UL label certifying that the filter meets Standard 586 is then applied to the filter.
Guaranteed Performance	N/A In a modern testing, each air filter is individually tested by, well-trained AAF Flanders® personnel before shipment to the customer. 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.
Additional Information	N/A They have broad application in cleanrooms and other areas requiring the very highest levels of contamination control, including: Semiconductor manufacturing Electronics Pharmaceutical processing Photo film manufacturing / processing Hospitals Universities Laboratories Food processing Asbestos abatement
Note	N/A AstroCel® I filters are available to meet all performance classes per the Institute of Environmental Sciences & Technology (IEST) Recommended Practice (RP) IEST-RP-CC001. AstroCel® I filters are available in a variety of construction materials and cell side configurations to fit AAF Flanders® and competitive framing systems or sealing designs.
