Key features include:

• Pressure independent control function.
• Volume control range 100% down to 10%.
• Low pressure loss over the terminal.
• Galvanised steel casing for strength and durability.
• Low height design.
• Rectangular shaped damper blade with side seals for linear control characteristic.
• Low leakage damper, less than 1% of Vnom at 750pa.
• Due to the very low air leakage levels achieved by this unit we recommend a 5nm actuator be used.
• Suitable for all control functions (VAC, CAV, shut-off etc.) to maximise system energy savings.
• Flo-Cross, 2 x 12 point averaging and signal amplifying airflow sensors, better than 2.5% accuracy even with irregular duct inlet conditions.
• Maintenance free.
• 25mm rigid fibreglass insulation with black tissue face.
