How to Perform Automatic Multi‑Point Tests
Use FanTestic to control multiple blower door fans simultaneously at varied pressures.
The system automatically steps through 7 test points spaced from 15 Pa to 60 Pa, with time‑averaging (10 s) and auto‑baseline correction, as defined by ASTM E779 and ANSI/RESNET/ICC 380.
The software collects flow-pressure data and generates a flow curve to compute accurate ACH50 values—especially critical in large structures where performance thresholds are tighter.
Custom Reporting Based on Test Standards
FanTestic allows exporting of test results to customizable report formats that reflect your chosen standard (e.g., LEED, ASHRAE, IECC).
Reports can include:
Flow vs. Pressure curve plots
Test environment metadata (temperature, date/time, fan IDs)
Pass/fail status per chosen leakage limit
Embedded charts, building diagrams, and compliance disclaimers
Device Strategies for Low & Mid‑Rise Buildings
Use multiple Model 7000 or Model 7310 fans for buildings with numerous zones or units. These fans weigh only ~23 lbs yet deliver high CFM capacity. Embedded accelerometers and ESC ensure smooth coordinated operation
DM‑32X gauges—color‑coded and WiFi/Ethernet-enabled—simplify multi-fan management and data logging. Multiple gauges can be networked for full-site coverage as part of QA workflows.
Conference Sneak Peek – Seattle Retrotec Training
During the Seattle Hands‑On Conference, attendees practiced live setup of triple-fan systems with DM‑32X control, set multi-point tests, and created real-time reports.
Trainers led breakouts on deploying multiple fans, troubleshooting fan coordination, and generating data exports for large-scale project documentation.
Why This Is a Breakthrough for Large-Building Testing
Scales efficiently to mid-rise apartment buildings or commercial venues using synchronized multi-fan setups.
Automated multi-point flows deliver greater accuracy and repeatability than single-point tests.
Custom reports reflect real results aligned to buyer, inspector, or certification program needs.
Built-in network and software tools enhance remote collaboration, QA workflows, and training synergy.
