DU200 Calibrated Fan (0.25 hp, ~10ā³ inlet):
Pressurizes or depressurizes ducts, delivering 5ā60āÆCFM at 25āÆPa depending on range plate.
Rugged plastic body with handle and built-in speed knob; includes two fan pressure sensors for precise airflow calculation.
Range Plates: Low, Mid, and Open restriction plates included to cover 7ā725āÆCFM at 25āÆPa
DMā2 Digital Dual-Channel Gauge: Automatically computes and displays results like CFM, EqLA, ACH50, with Cruising control (Set Pressure/Speed) and @Pressure mode
Umbilical Pressure Tubes & Speed Cable: Color-coded (yellow, green, blue) with 20ā² length and solid taper connectors for foolproof setup 10ā³Ć12ā² Flex Duct & Flange: Easy connection to a register or air handler cabinet
Grill Mask, Power Cord, Battery Charger, and QuickGuides (DU200 & DMā2) all packaged in a sturdy tool bag
Accurate airflow readings via DMā2 assisted fan pressure sensing.
Works in both depressurization and pressurization modes for dual-use testing.
Swapable inlet plates allow accurate measurements across a wide flow range without needing multiple fans.
Converts raw pressure to meaningful results (e.g., CFM@25āÆPa, EqLA, flow/area, ACH).
Includes advanced features like Set Pressure/Speed control and @Pressure interpolation.
No laptop needed; manual knob or gauge-controlled operation.
Compact design and included tool bag make field transport and setup fast and efficient.
Measure total duct leakage or duct leakage to outdoors (paired with a blower door).
Perform pressure-dependent airflow tests in residential HVAC systems.
Ideal for compliance testing with Title 24, Energy Star, RESNET, and other standards.
Field training and demonstration applications using simulated leaks or hardware modifications.
Efficiency: Complete setup-to-results in under 20 minutes, straight from the case.
Accuracy: Reliable CFM measurements backed by NIST-traceable calibration.
Flexibility: Suitable for both skilled professionals and those newer to duct leakage testing.
