Alnor LoFlo Balometer Capture Hoods

Low-volume ventilation plays a critical role in advanced buildings and controlled environments. Alnor LoFlo Balometer capture hoods help researchers characterize these subtle flows with direct volumetric measurements at diffusers and grilles. The LoFlo design supports repeatable measurements where small changes in flow can influence thermal comfort, contaminant control, and energy performance.

Engineered for R&D:

• Sensitivity and stability at low flows support studies of displacement ventilation, low-energy air distribution, and specialized lab spaces.
• Interchangeable hood sizes help match device geometry to outlet dimensions, improving capture efficiency and measurement consistency.
• Portable frames and intuitive interfaces reduce setup time during multi-point test plans and iterative experiments.
• Data capture options enable archiving and analysis, supporting comparative studies and peer-reviewed documentation.

Applications include:

• Evaluating low-air-change strategies and their impact on conditioning and contaminant transport.
• Characterizing diffuser performance at turn-down conditions for VAV systems.
• Mapping airflow in clean environments and controlled laboratory spaces.
• Benchmarking prototypes of energy-efficient ventilation components.

LoFlo Balometer hoods integrate into broader measurement campaigns that include pressure, velocity, temperature, and particle metrics. Pair with micromanometers for pressure diagnostics and thermal anemometers for low-velocity mapping to build a comprehensive picture of system behavior.
