Vents type A1, A1S & Α2
The orifices of the series A1 (one row of adjustable blades without damper) and A1D (one row of blades with damper) are recommended for applications which require the adjustment of the air flow to a level (horizontal or vertical). They perform well for temperature differences -8oC ÷ -7oC for cold air, -7oC ÷ 10oC for hot air and for providing from 1, 3 to 3, 0 m3/h for 0, 09 m2 floor surface.
There is also the ability of making orifices A1S & A1SD types (a row of blades with 45o inclination with or without tamper respectively) for wall or airway installation when we want to distribute the only to one direction.
The orifices of the series A2& A2D (two rows of adjustable blades with or without tamper respectively) are recommended for applications requiring air flow adjustments to two levels, with we succeed great flexibility and adaptability to local demands. They perform well to temperature differences -7oC ÷ -5,5oC for cold air, -7oC ÷ 10oC and for providing from 1, 7 to 3,4m3/h for 0,09m2 floor surface.
They are made of anodized aluminum and are appropriate for wall or airway installation. Each blade is independently adjusted and thanks to its aerodynamic shape a reduction in pressure drop and silent operation is succeeded.
Blades retain their settings in every condition of pressure and air speed.
