Product Spotlight
04/01/2005
Air quality is a key factor in most any cleanroom environment and when it comes to filtration equipment, the choices can be overwhelming. Features such as accessibility, service life, and the types of contaminants that can be filtered are important considerations and can vary from product to product. To help get you started, we’ve gathered information on some of the newest air filters on the market in this month’s Product Spotlight.
High volume HEPA filters
 |
The Aerostar HV (High Volume) HEPA filters for demanding applications are constructed with a robust, aluminum frame and Filtration Group’s proven minipleat technology. The Aerostar HV offers the ultimate in reliable filtration for the most critical of environments. Specifically designed to perform in adverse, demanding, critical and sensitive conditions, the Aerostar HV not only provides security, but offers extremely low total operating costs. The higher airflows of the Aerostar HV require less hardware and filters, and the lower pressure drop conserves energy. The minipleat technology provides better airflow, and 430 square feet of media means a longer service life. The Aerostar HV has a high dust-holding capacity, allowing for fewer filter changeouts, making this product cost effective and minimizing total operating costs. The Aerostar HV removes a broad range of airborne contaminants including fine dust, smoke, bacteria, viruses, soot, pollen and radioactive particles. This filter is widely used to replace all conventional aluminum separator HEPA filters and other high efficiency HEPA products. Final filter applications include: electronic, nuclear, pharmaceutical, hospital, laboratory, aerospace, food processing and optical facilities. This product can also be used as a prefilter for cleanroom environments and other critical applications.

High-efficiency HEPA filters
 |
Tri-Dim Filter Corporation has announced the release of an innovative new high efficiency filter-the TRI-PURE E. The TRI-PURE E utilizes state of the art technology to offer high efficiency, low resistance and a cost-effective replacement for standard separator-style HEPA filters. The TRI-PURE features a 130-mm recessed pack that offers less resistance to airflow than traditional HEPA filters. The media pack pleats are separated and secured by an adhesive bead separator. The TRI-PURE separator system is precisely applied to promote uniform airflow. The media pack is manufactured on a computer-controlled pleater to offer consistent and repeatable media packs in an ISO 9001-2000 Certified Cleanroom facility. Tri-Dim Filter Corporation is a full-line filter manufacturer able to provide a full range of HVAC filtration products and services.

Replaceable terminal module
 |
The Pharma-Replaceable Terminal Module (P-RTM) is designed for applications that require frequent filter testing and routine cleaning procedures as found in hospitals (surgical suites) and pharmaceutical and biotechnology cleanrooms. The P-RTM is easy to install, change filter and provides an optimum service life. A gel seal between the filter and hood eliminates any by-pass leakage. The P-RTM uses a 2-inch (51mm) or 4-inch (100mm) minipleated media pack with efficiency of 99.99 percent at 0.3-μm or 99.9995 percent at 0.12-μm particle size. The low profile module is manufactured out of either aluminum or stainless steel. The P-RTM is designed to fit into T-bar ceilings and plaster ceilings. Standard features include collar, diffuser/damper, stainless-steel grill and static pressure port. Each unit is subjected to a factory 5-inch positive pressure W.G. leak test. Due to varying end-user requirements, custom engineered units are available. Other benefits of the P-RTM include: an adjustable butterfly damper (range of 30 to110 FPM) creates a balanced and uniform airflow resulting in longer service life; lower cost of ownership-only the filter is changed, not the entire unit; rugged leak-free construction available in aluminum or stainless steel; and access to aerosol injection system, test port and damper control for easy service of filter. The P-RTM is designed to optimize performance in filtration applications for pharmaceutical, biotechnological, medical microelectronics, semiconductors, and food processing industries, as well as surgical center operating rooms and isolation areas.
