Applications
VLSI-grade HEPA filters like this one are used in laminar flow hoods, cleanroom ceilings, and fan filter units (FFUs) where ISO Class 4 (Class 10) or better air cleanliness is required. The VLSI designation was developed specifically for semiconductor wafer fabrication, where sub-micron particulate contamination directly impacts chip yield — even a single particle landing on a wafer during photolithography or deposition can render a die defective. These filters are a standard component in horizontal and vertical laminar flow workstations, wafer-handling benches, and cleanroom bay/chase ceiling plenum systems. They are also used in life sciences research, optical coating chambers, and any environment requiring extremely low particle counts at the work surface. Flanders (now part of AAF International) has been a major supplier of VLSI and ULPA grade filters to the semiconductor industry since the 1980s and 1990s, when VLSI chip geometries drove rapid development of more stringent cleanroom standards.
This Flanders Laminar Flow Grade VLSI HEPA Filter (PN 0-009-2-19-07-SU-00-F2-22J22J) is in used condition and shows visible signs of prior service. The aluminum frame has chipped and crumbling sealant at two of the corners, as shown in the detail photos. The pleated filter media shows dust accumulation at the tops of the pleats, consistent with prior use in a cleanroom environment. The filter has not been re-tested for efficiency after removal from service. Please review all photos carefully — this filter is sold as-is in its current state.
