Thumbnail Filmstrip of Glass Fiber Filter w/ Center Hole 2.25" OD x 1.0" ID for CI-700 Cascade Impactor Images
The TE-G653-2.25X1 glass fiber filter is specifically designed for use with the CI-700 Cascade Impactor, featuring a precision-cut 1.0" center hole that allows proper airflow through the impactor stages while providing efficient particle collection on the surrounding glass fiber substrate.
Technical Specifications
- Outside Diameter: 2.25 inches
- Inside Diameter (hole): 1.0 inch
- Material: Type A glass fiber
- Compatible with CI-700 Cascade Impactor systems
Collection Performance
Type A glass fiber filter media is the most commonly used material for collection substrates. Deposition of the particles into the glass fiber lattice improves particle retention and reduces possible re-entrainment. The open center design allows sampled air to pass through to subsequent impactor stages while larger particles impact and collect on the glass fiber surface.
Compatibility
This filter is engineered specifically for the CI-700 Cascade Impactor and other Tisch Environmental cascade impactor systems. The slotted impactor design separates particulates from larger than 7.2µm to less than 0.49µm while operating at a flow rate of 40cfm. Suspended particulates enter through the hivol cascade impactor through the first set of parallel slots on the first stage. Particulates that are too large to travel to the next stage are impacted on the collection substrate and the smaller particles remain in the air stream and travel to the next stage.
Installation and Handling
It is recommended to lightly tap each glass fiber collection paper before inserting it into the Impactor to shake off any excess fibers. Position the filter with the rough side facing up for optimal particle collection efficiency. The collection substrate is centered over the slots, rough side up.
Applications
Hivol Cascade impactors are used for particulate fractionating on high volume air samples. The cascade design of this impactor collects particles on small light weight substrates that are analyzed for respirable particulate matter. These filters enable size-selective particle sampling for environmental monitoring, industrial hygiene assessments, and ambient air quality studies requiring particle size distribution analysis.
