Alnor Capture Hoods

Accurate airflow at the diffuser or grille is the cornerstone of effective HVAC balancing. Alnor capture hoods provide a practical, field-ready solution that helps teams move quickly through large facilities while gathering repeatable volume flow measurements.

Why Alnor capture hoods:

• Speed and ergonomics: Lightweight construction and easy-to-read displays support high-throughput surveys across production floors and office areas.
• Flexibility: A variety of hood sizes accommodate common diffuser and grille dimensions, minimizing bypass and improving measurement consistency.
• Measurement clarity: Integrated flow calculations give immediate volume readings, helping crews make adjustments on the spot.
• Documentation made easier: Optional logging captures time-stamped results, which simplifies reporting for commissioning, preventative maintenance, and audits.
• Field durability: Rugged frames and cases stand up to frequent transport and varied site conditions.

Typical industrial applications:

• Commissioning and re-commissioning: Establish airflow baselines after upgrades or seasonal changeovers.
• Energy optimization: Identify over-delivery in select zones and balance systems to support energy-saving initiatives.
• Troubleshooting: Verify delivered airflow to resolve temperature complaints and pressurization issues.
• Process-adjacent spaces: Check airflow in corridors, gowning areas, and near production lines to support environmental stability.
• Routine verification: Incorporate periodic airflow checks into facility maintenance plans for better visibility across buildings.

Best practices for consistent data:

• Match hood size to the outlet face and follow a consistent placement routine.
• Allow readings to stabilize before recording values, especially near large diffusers or complex flow patterns.
• Pair with micromanometers for duct pressure checks when diagnosing upstream issues.

Selecting your kit:

• Consider the range of diffuser sizes in your facility and choose hood sizes accordingly.
• Determine the value of logging and connectivity based on your reporting requirements.
• Review accessory needs, such as extension poles, to reach ceiling heights safely and efficiently.
