Airflow Instruments Capture Hoods

Capture hoods are a fast, reliable way to quantify volumetric airflow at diffusers and grilles during commissioning, testing, and routine maintenance. In manufacturing facilities, where airflow impacts worker comfort, process performance, and product quality, consistent measurements support better decisions and fewer callbacks.

Purpose-built for industrial use, these hoods combine a stable frame, optimized hood fabric, and a well-sealed skirt to help minimize bypass and improve repeatability at the point of measurement. Clear, backlit displays and intuitive menus guide technicians through area entry and unit selection, enabling quick transitions between cubic feet per minute and liters per second. Teams can move from supply to return measurements with minimal setup, speeding room-by-room balancing during shutdown windows or shift changes.

Typical applications include:

• HVAC balancing across production lines, warehouses, and mixed-use spaces
• Makeup air validation for process exhaust and dust collection
• Verification of air changes and ventilation rates in labs and cleanrooms
• Troubleshooting comfort complaints and uneven distribution
• Energy conservation measures that target fan speeds and schedules

Capture hoods support better documentation. Onboard logging allows users to record outlet ID, airflow, temperature, and notes in one place, then export data for commissioning reports or audits. This reduces manual transcription, helps avoid data gaps, and supports internal SOPs and regulatory expectations.

Selection considerations:

• Hood size and shape options to fit your diffuser mix
• Weight and ergonomics for one-person operation
• Measurement range for both low-flow and high-flow outlets
• Data logging capacity and file export format compatibility
• Accessories for hard-to-reach ceilings or high-return grilles

When paired with micromanometers and anemometers, capture hoods help form a complete ventilation toolkit. Use them during system start-up, periodic rebalancing, and after equipment changes to confirm airflow delivery aligns with design intent. For operations focused on throughput and quality, that added confidence can translate into more stable environmental conditions and improved energy performance.
