TE-1004-BL, 110 Volt Brushless Motor Assembly for PUF Systems SKU: TE-1004-BL

The TE-1004-BL is a 110-volt brushless motor assembly specifically designed for Polyurethane Foam (PUF) high volume air sampling systems. This brushless motor assembly eliminates the need for carbon brush maintenance and produces no emissions, making it ideal for long-term unattended ambient air monitoring operations.

Brushless Motor Technology

Brushless motors do not use motor brushes or require maintenance and are higher in cost but do not have any emissions. The TE-1004-BL delivers consistent vacuum performance throughout extended sampling periods without the brush replacement intervals required by traditional brush-style motors. This maintenance-free operation ensures uninterrupted data collection for critical air quality monitoring programs.

PUF System Integration

PUF samplers operate between 125-250 lpm (liters per minute) and are designed to meet the requirements described for sampling using US EPA method TO-4A, TO-9A, and TO-13A. The PUF high volume air sampler collects airborne particulate and vapor contaminants, typically used to collect volatile organic compounds, airborne pesticides, and PFAS in ambient air.

Flow Control and Performance

The flow is pulled through a critical orifice with the brushless vacuum blower motor assembly which is used to control and calculate the ambient flow rate. The TE-1004-BL integrates with Tisch Environmental's flow control systems, including manual motor speed controllers and the PLUS controller for precise flow rate management.

System Compatibility

The TE-1004-BL brushless motor assembly is compatible with complete PUF sampling systems including:

• TE-1000 series PUF samplers
• TE-1002 dual sampling modules
• TE-1003 flow venturi and calibration valves
• TE-5010 motor voltage controllers
• TE-5007 seven-day mechanical timers

Related components include TE-1004-1 motor flange for PUF housing, TE-1004-2 flange gaskets, and TE-1004-3 PUF motor housing. For 220-volt applications, the TE-1004X-BL provides equivalent brushless performance at international voltages.

EPA Compliance Applications

The TE-1004-BL supports ambient air quality monitoring programs requiring compliance with EPA TO-13A for pesticide and semi-volatile organic compound sampling. Samples in accordance with U.S. EPA Method TO-4, "Method for the Determination of Organochlorine Pesticides and Polychlorinated Biphenyls in Ambient Air". These systems provide the reliability and precision required for regulatory monitoring, source assessment, and environmental compliance verification.
