Air Capture Hoods

Why Use Air Capture Hoods

Balancing supply and exhaust volumes is foundational for cleanroom classification and room pressurization. Capture hoods provide direct volumetric readings at the outlet, helping teams confirm air change rates, verify diffuser performance, and diagnose room-level issues. By speeding measurements, they support efficient commissioning and reduce downtime for production or research operations.

Core Capabilities

• Volumetric Flow Measurement: Direct readings in CFM or L/s across common flow ranges.
• Interchangeable Hoods: Adapt to square, rectangular, and circular diffusers.
• Integrated Micromanometer: Accurate pressure-based calculations with clear display.
• Data Logging: Store, tag, and export results for reports and audits.
• Lightweight Construction: One-person operation and easy transport.

Applications in Life Sciences

• Cleanroom Supply and Return Balancing
• Pharmacy and Compounding Room Surveys
• Lab Renovation and Commissioning Projects
• Troubleshooting Hot/Cold Spots or Pressure Drift
• Energy Optimization Without Compromising Ventilation Targets

Selection Considerations

• Hood Size Coverage: Confirm common diffuser sizes in your facility.
• Flow Range and Accuracy: Match to expected volume rates.
• Turbulence Handling: Look for features that support stable readings at modern diffusers.
• Ergonomics: Weight, handle design, and setup speed matter in repetitive tasks.
• Calibration and Service: Plan annual or semiannual calibration based on SOPs.

Best Practices

• Use consistent measurement locations and heights.
• Record upstream system conditions to contextualize readings.
• Combine with pressure and velocity measurements for a complete picture.
• Trend results over multiple seasons to understand system behavior.
