Thumbnail Filmstrip of TE-10557PM10BLX VFC for PM10 Hi-Vol Air Sampler, 220V Brushless Systems Images
The TE-10557PM10BLX Volumetric Flow Controller (VFC) maintains precise flow control for PM10 high volume air samplers operating with 220-volt brushless motor systems. This controller ensures compliance with 40 CFR Part 50, Appendix J requirements for EPA-designated reference method PM10 sampling by maintaining constant volumetric flow rates throughout the 24-hour sampling period.
Flow Control Technology: The VFC operates by continuously measuring actual flow rate and automatically adjusting the motor speed to compensate for filter loading and atmospheric pressure variations. The flow rate through the sampler's inlet must be maintained throughout the sampling period within the design flow rate range specified by the manufacturer. The controller includes a calibrated VFC orifice and lookup table for accurate flow measurement and control.
Key Features:
- 220-volt operation optimized for international installations
- Compatible with brushless motor systems for reduced maintenance
- Includes calibrated VFC orifice assembly
- Pre-programmed lookup table for flow calculations
- Maintains flow within ±2% of setpoint throughout sampling cycle
PM10 Compliance Requirements: Particle size discrimination by inertial separation requires that specific air velocities be maintained in the sampler's air inlet system. This VFC ensures the sampler maintains the required flow rate for proper PM10 size-selective inlet performance, critical for accurate determination of particulate matter concentrations in ambient air monitoring.
System Compatibility: Designed specifically for Tisch Environmental PM10 high volume air samplers equipped with 220-volt brushless motor assemblies. The controller integrates with TE-6001 PM10 size-selective inlets and compatible filter holder assemblies. Verify your sampler's motor voltage and type before ordering to ensure proper system integration.
Installation Notes: The VFC mounts directly to the sampler control panel and connects to the motor control circuit. Complete installation requires connection to the motor assembly, flow sensor, and sampler timer system. Refer to your sampler's operation manual for specific wiring diagrams and calibration procedures.
