Airflow Instruments Capture Hoods

Capture hoods are the TAB workhorse for verifying supply and return airflows at terminals. Airflow Instruments models are designed to help you move faster through large buildings while maintaining measurement consistency.

What Sets These Capture Hoods Apart

• Backpressure Compensation: Bases are designed to help stabilize readings by reducing the influence of added system resistance.
• Multiple Hood Sizes: Swap hoods to match common diffuser and grille dimensions, from residential registers to large commercial lay-in tiles.
• Integrated Micromanometer: High-resolution pressure and flow computation provide stable readings with minimal manual calculation.
• Data and Reporting: Optional Bluetooth connectivity and app workflows help you tag locations, record setpoints, and export reports aligned with TAB deliverables.

Applications

• Commissioning: Verify design airflows at terminals during new construction or major renovations.
• Rebalance and Seasonal Checks: Document changes after system modifications or filter replacements.
• Troubleshooting: Isolate rooms with low flow, imbalanced zones, or occupant comfort complaints.
• Healthcare and Labs: Support ventilation verification in spaces with airflow direction and pressure requirements.

Measurement Tips

• Seal and Center: Ensure the hood fully covers the diffuser with minimal gaps.
• Stabilize: Allow readings to stabilize, then record multiple measurements to obtain a reliable average.
• Orientation: Maintain consistent hood orientation relative to the diffuser to support repeatability.
• Environmental Conditions: Note temperature and barometric pressure if your reporting requires density-corrected volume.

Selection Guidance

• Hood Inventory: Choose a kit with the hood sizes you encounter most often to reduce field changes.
• Workflow Integration: Consider models with mobile app support when your team needs photo tags, room IDs, and fast export to client templates.
• Range and Resolution: Confirm low-flow performance for spaces such as healthcare isolation rooms or residential rooms, and higher ranges for large commercial diffusers.

Well-executed terminal measurements support accurate balancing, better comfort, and ventilation performance. Airflow Instruments Capture Hoods help you cover more terminals per day and keep your documentation clear and consistent.
