      The TE-300-310 Mass Flow Controller (MFC) delivers precise volumetric flow control for high volume ambient air sampling systems. This brush motor-driven controller maintains constant flow rates despite changing conditions including filter loading, line voltage variations, ambient temperature fluctuations, and barometric pressure changes.

      Operating Principle

      The TE-300-310 uses mass flow sensing technology to monitor actual volumetric flow and automatically adjust motor speed to maintain the programmed setpoint. The controller maintains flow rate precisely constant over the selectable range of 15 to 50 scfm and provides correction for filter loading and changes in line voltage, ambient temperature, and ambient pressure. This closed-loop control ensures EPA compliance throughout extended sampling periods.

      Key Specifications

      • Input Power: 110 volts, 50/60 Hz
      • Flow Range: 15-50 SCFM (0.42-1.42 m³/min) selectable
      • Motor Type: Brush-style with replaceable carbon brushes
      • Control Method: Mass flow feedback with automatic correction
      • Housing: Anodized aluminum construction

      Sampler Compatibility

      The TE-300-310 is the standard flow controller for Tisch Environmental high volume samplers including:

      • PM10 ambient air samplers with EPA designation RFPS-0202-141
      • TE-230 Series High Volume Cascade Impactors
      • TSP (Total Suspended Particulate) samplers
      • PM2.5 samplers requiring constant flow control

      For 220V applications, order TE-300-310X. For brushless motor operation, consider TE-300-310-BL (110V) or TE-300-310-BLX (220V) models.

      Maintenance

      Regular brush inspection and replacement ensures reliable operation. Replacement brush set TE-33384 is available for 110-volt models. The controlled flow operation extends brush and motor life compared to constant-voltage operation by reducing average motor loading.

      EPA Compliance

      Designed for US EPA Reference Method Sampling per 40 CFR Part 50, Appendix J for PM10 monitoring. The high accuracy inherent in controlled-flow sampling requires known, constant flow rates that this controller maintains precisely.
