APPLICATION

The AFM-R Airflow Monitoring Stations consist of one or more FloXact™ air velocity probes, factory mounted in a rugged galvanized steel enclosure. Multiple sets of total and static pressure measurement points, placed along the length of each FloXact™ probe on an equal area base, traverse the airflow and average the measured pressures. Factory installed static and total pressure signal lines connect the individual FloXact™ probes together and terminate at the galvanized enclosure for field connection. The AFM-R is suitable for installation in ducts, fan inlets, etc. The AFM-R can be used in applications ranging from HVAC in commercial buildings to laboratories, pharmaceutical and electronics manufacturing, and healthcare settings.

AIR-TRAC™ System

AFM units are often used in combination with VAV systems to monitor the supply air volume in a large room or floor. The supply air volume signal is used to control/balance a VAV terminal in the corresponding return air duct. This means that the system is balanced under all load conditions, ensuring quiet operation and the most energy-efficient installation.

FEATURES AND BENEFITS

Housing: Galvanized steel construction with ribs (1.2 mm).
Flanges: 30mm, corner holes ø10x17mm
Operating temperature +10 to 50°C
Storage temperature 0 to 70°C, max RH 95%.
Optional double-walled construction (25mm insulation).
Optional with air flow director, 99.5% free space.
Other construction available on request.
Airflow sensor: Multi-point averaging FloXact™ sensor. Unique shape creates an amplified signal (minimum 2.5x Pdyn) with very low pressure drop and noise level.
All regulators are pressure independent and factory calibrated.
When units are ordered with controls supplied ‘free of charge’ by third parties, wiring diagrams, calibration instructions, calibration tools and mounting instructions must be supplied free of charge.
All controls are mounted on the right side of the unit as standard when looking in the direction of the airflow unless otherwise requested.
