25mm Glass Fiber Filter, Grade G653, 100/pk SKU: TE-G653-25

25mm Glass Fiber Filter, Grade G653, 100/pk

The TE-G653-25 is a precision-manufactured 25mm diameter glass fiber filter designed for particulate collection in air quality monitoring applications that require 99% minimum collection efficiency for 0.3 µm particles as measured by the DOP test (ASTM-2986). This Grade G653 filter provides reliable performance in environmental monitoring and analytical applications where consistent particle retention is critical.

Technical Performance

Manufactured from borosilicate glass fibers, this filter delivers depth filtration through its complex fiber matrix structure. Glass fiber filters offer excellent thermal stability and can operate at high temperatures, making them suitable for demanding laboratory and industrial applications with high dirt-holding capacity and fast flow rates. The Grade G653 designation ensures consistent manufacturing standards for EPA-compliant sampling protocols.

Key Specifications

• Diameter: 25mm
• Material: Borosilicate glass fiber
• Grade: G653
• Collection efficiency: 99% minimum for 0.3 µm particles (DOP test)
• Package quantity: 100 filters per pack
• Filter type: Depth filtration

Applications

These filters are typically used with air samplers for applications specified in 40 CFR Part 50, including TSP and PM10 monitoring where glass fiber materials with collection efficiency of 99% minimum are required. Common applications include:

• Ambient air quality monitoring
• Laboratory air sampling analysis
• Environmental compliance testing
• Pre-filtration for membrane filter protection
• Particulate collection for gravimetric analysis

Compatibility

The 25mm diameter makes this filter compatible with standard laboratory filtration equipment and sampling assemblies designed for 25mm filter media. These filters work with vacuum filtration assemblies, sampling cassettes, and analytical equipment requiring precise particle collection at this diameter specification.
