Ventilating grilles Registers When adjusting the system, desired operating conditions are obtained by the means of ventilation elements control. Registers are installed for additional air volume control, thus influencing air velocity and throw distance as well. All types of registers, except type of register F, are made of sheet steel and corrosion protected with dipcoat processing in blackwater soluble colour. Upon customer s request registers can be made of galvanised sheet steel and coloured in any colour. Typ of register F is made of plastics. VENTILATING GRILLES, VENTILATING VALVES CIRCULAR DIFFUSERS, SQUARE DIFFUSERS F Register has wide counter-directional blades which can be moved with screw-driver via the gear wheel. It is used to control the air flow volume.blades are made of plastics. S Register has fixed deflector and slider which opens and closes the slots. Due to inclined deflection, air volume damper S is particularly useful for longer grilles, because air flow is evenly distributed throughout the grille. T Register has fixed deflector and slider which opens and closes the slots. It isused to control and deflect the air flow from the duct. PP Perforated sheet steel ( %) is used to split the air jet.
