BAM Glass Fiber Filter Tape Roll - 30mm x 31m - 90 Day Supply SKU: SF17934

The SF17934 BAM Filter Tape is a continuous roll of glass fiber material specifically designed for Beta-ray Attenuation Monitoring (BAM) instruments and related applications. This 30mm x 31m roll provides approximately 90 days of continuous operation for particulate matter monitoring systems that employ beta attenuation measurement principles.

Technical Operation

BAM instruments utilize a 14C (carbon-14) beta source that emits high-energy electrons through the filter tape. At the end of each sample hour, particulate matter collected on the tape causes attenuation of the beta ray signal, which is used to determine the mass of particulate matter and calculate volumetric concentration in ambient air. The system measures beta ray transmission across clean filter tape, advances the tape to the sampling inlet where particulate matter is deposited, then returns the tape for remeasurement.

Key Specifications

• Dimensions: 30mm width x 31m length
• Material: Continuous glass fiber construction
• Operating duration: 90 day supply for standard BAM operation
• Compatible with various BAM models including BAM-1020, E-BAM, and similar instruments

Compatibility

This filter tape is compatible with EPA Federal Equivalent Method (FEM) designated BAM instruments for continuous PM2.5 and PM10 monitoring. Standard BAM systems operate with 16.67 liters/minute actual flow and utilize continuous glass fiber filter tape for 70+ day operation per roll. The SF17934 provides extended 90-day operation compared to shorter duration alternatives like the SF17933 (60-day supply).

Compatible BAM instrument applications include:

• EPA PM2.5 and PM10 continuous monitoring systems
• Emergency response situations and rapid deployment monitoring
• Permanent installations on rooftops, near roads, and at industrial sites
• Perimeter monitoring and remote monitoring applications

Maintenance Notes

Filter tape changes are part of routine periodic maintenance for BAM systems. The 90-day supply duration reduces maintenance frequency compared to shorter-duration tapes. Proper tape installation following manufacturer procedures ensures continuous, uninterrupted particulate monitoring operation. Once initialized with fresh tape, BAM instruments operate continuously except during calibration verification periods.

Applications

This filter tape enables hourly PM2.5 concentration reporting and supports BAM instruments that measure particulate mass concentration in ambient air using beta ray attenuation principles. The glass fiber construction provides accuracy and precision consistent with EPA requirements for Class III PM2.5 and PM10 measurement, delivering real-time results without correction factors regardless of season or geographic location.
