What You Get in the Kit
DU200 Calibrated Fan (0.25 hp, ~10″ inlet):
Pressurizes or depressurizes ducts, delivering 5–60 CFM at 25 Pa 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 7–725 CFM at 25 Pa
DM‑2 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 20′ length and solid taper connectors for foolproof setup 10″×12′ Flex Duct & Flange: Easy connection to a register or air handler cabinet
Grill Mask, Power Cord, Battery Charger, and QuickGuides (DU200 & DM‑2) all packaged in a sturdy tool bag
What You Get in the Kit
High Precision Fan System
Accurate airflow readings via DM‑2 assisted fan pressure sensing.
Works in both depressurization and pressurization modes for dual-use testing.
Range Plate System
Swapable inlet plates allow accurate measurements across a wide flow range without needing multiple fans.
DM‑2 Gauge Integration
Converts raw pressure to meaningful results (e.g., CFM@25 Pa, EqLA, flow/area, ACH).
Includes advanced features like Set Pressure/Speed control and @Pressure interpolation.
Easy Connections
- Color-coded umbilical keeps tubing organized, precise fittings reduce mistakes.
- Convenient flex duct and flange simplify field setup.
Plug-and-play & Portable
No laptop needed; manual knob or gauge-controlled operation.
Compact design and included tool bag make field transport and setup fast and efficient.
Typical Use Scenarios
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.
Why the DU200 Stands Out
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.
