High Volume Polyurethane Foam Air Sampler for Pesticides and Semi-Volatile Organics

The TE-1000BLXZ is a high volume air sampler for the collection of airborne volatile organic compounds and particulate matter using a dual sampling module configuration. The PUF high volume air sampler collects airborne particulate and vapor contaminants through specialized polyurethane foam media, making it ideal for ambient air monitoring of pesticides, PFAS compounds, and other semi-volatile organic compounds (SVOCs).

EPA-Compliant Sampling Method

These systems are designed to meet the requirements described for sampling using US EPA method TO-4A, TO-9A, and TO-13A. The dual sampling approach captures both particulate matter on filter media and vapor-phase contaminants on the polyurethane foam substrate below, providing comprehensive collection for complex organic pollutants typically found in ambient air monitoring applications.

Technical Operation

This sampler operates between 125-250 lpm and uses either a manual motor speed controller or the Tisch Environmental PLUS controller to control the flow rate. The flow is pulled through a critical orifice with either a brushless or brush style vacuum blower motor assembly which is used to control and calculate the ambient flow rate. The system includes a magnehelic gauge for monitoring differential pressure across the critical orifice for flow rate determination.

Key Specifications

Flow Rate Range: 125-250 L/min (typical operating range)
Motor Type: Brushless vacuum blower assembly
Timer: 7-day mechanical timer for reliable start/stop control
Power Requirements: 220V, 60Hz
Flow Control: Manual motor speed controller
Housing: Anodized aluminum weather shelter

Brushless Motor Advantage

The brushless motor configuration eliminates the routine maintenance requirements of carbon brush replacement while delivering consistent performance in continuous field operations. This motor design provides extended service life and reduced maintenance costs compared to traditional brush-style motors, making it ideal for remote monitoring locations or extended sampling campaigns.

Sampling Applications

Designed for environmental monitoring professionals conducting ambient air quality assessments for:

Organochlorine pesticides and PCB monitoring per EPA TO-4A
Polycyclic aromatic hydrocarbon (PAH) sampling per EPA TO-13A
PFAS compound collection in ambient air
Source emission assessments near industrial facilities
Background air quality monitoring for regulatory compliance

System Components and Operation

The TE-1000BLXZ includes all core components needed for field deployment: brushless motor assembly, mechanical timer, magnehelic pressure gauge, critical orifice (venturi), and anodized aluminum shelter. The mechanical timer provides dependable scheduling without the complexity of electronic controls, while the manual flow controller allows operators to adjust sampling rates based on site-specific requirements and sampling duration.
