Blauberg Iso-ZS 250 4E
Supply and exhaust ventilation systems installed in premises with high requirements to the noise level.Compatible with Ø 250 or 315 mm round air ducts.
Galvanized steel casing internally filled with 30 mm thermal- and sound-insulating layer made of non-flammable foamed polyurethane.Connecting spigots are equipped with rubber seals.External terminal block for power supply.Lifting lugs facilitate hanging and transportation operations.Modifications with two Ø 250 mm suction spigots are available specifically for multi-port ventilation solutions (Iso-ZS 315/2x250).
Mounted with round air ducts.Suitable for installation in any mounting position with respect to air flow direction in the system, fixed with supports or brackets.Suspended to ceiling with mounting lugs.Flexible air ducts are fixed on fan spigots with clamps.
Four- or six-pole asynchronous motor with external rotor and double intake centrifugal impeller with forward curved blades.The motor is installed on specially designed vibration-damping mounts to absorb vibration and noise.Equipped with ball bearings for longer service life.Integrated thermal protection with automatic restart.Dynamically balanced turbine.
Smooth speed control with an external thyristor controller or step speed control with an external auto transformer (both available upon separate order).
MODIFICATIONS AND OPTIONS
