PODESUVAC ZADEN VENTIL Constant Air Flow Regulators (Dampers)

Dampers or constant airflow valves are suitable when

constant air flow or specific air distribution is required.

They reduce or increase ventilation or air conditioning air

duct system air flow, through passive operation without

mechanical, electrical, pneumatic energy, sensors or

control.

n Their operation is based on a special silicon hourglass

shaped “balloon” at 0 mm static pressure.

n When the static pressure increases, the balloon’s volume

increases accordingly thus reducing the available air cross

section and stabilizing air flow.

n Their frame is made of steel sheet with a foam insulation

tape on the perimeter for perfect connection.

n Dampers are manufactured in nominal diameters and are

suitable for operation with the same diameter air ducts.

n The silicon “balloons” are factory adjusted and cannot be

adjusted on site. Airflow regulation accuracy is ±10%.

n CAR series is available in two types:

n CAR-LP low pressure (50-200 Pa) and 15-650 m3/h

air flows.

n CAR-HP high pressure (150-600 Pa) and 110-1.600 m3/h

air flows.
