The TE-PNY1123X is a high volume air sampler specifically configured for PUF (polyurethane foam) sampling of volatile organic compounds and airborne pesticides. This system collects both airborne particulates and vapor-phase contaminants using a dual sampling module with the upper chamber collecting particulates onto filter media and the lower chamber housing a glass cartridge containing polyurethane foam.

Mass Flow Control Operation

The mass flow controller continuously monitors actual volumetric flow using an integrated flow sensor and automatically adjusts the brush motor speed to maintain the programmed flow rate. Mass flow controllers measure and control gas flow by comparing actual flow rates to user-defined setpoints and adjusting control valves to maintain the desired flow. This closed-loop system compensates for filter loading and environmental conditions that would otherwise cause flow drift during sampling periods.

Key Specifications

Power: 220V, 50Hz brush motor configuration
Flow Control: Mass flow controlled (MFC) with integrated sensor feedback
Timer: 7-day mechanical timer with bright yellow dial and on/off trippers
Motor Type: Brush-style motor requiring periodic brush maintenance
Shelter: Anodized aluminum housing for field durability

EPA Method Compliance

The PUF high volume air sampler meets requirements described in US EPA methods TO-4A, TO-9A, and TO-13A for sampling and analysis of toxic organic compounds in ambient air. The sampling module consists of a filter and glass sampling cartridge containing PUF to concentrate PAHs and other semi-volatile organics from air. Operating flow rates typically range between 125 and 250 liters per minute.

Applications

Designed for ambient air monitoring programs requiring:

Pesticide and herbicide monitoring in agricultural areas
Polycyclic aromatic hydrocarbon (PAH) assessment
Semi-volatile organic compound (SVOC) sampling
Source assessment and emission studies
Long-term environmental monitoring with regulatory documentation

Maintenance Requirements

The brush-style motor requires periodic carbon brush replacement as part of routine maintenance. The mechanical timer provides reliable field operation without digital components, making it suitable for remote monitoring locations. The mass flow control capability makes this sampler suitable for applications requiring precise flow documentation for regulatory compliance where filter loading varies significantly during sampling periods.
