BOX RLQ PLUS 400 T4 0,75kW

VENTILATION BOX WITH BACKWARD IMPELLER

MANUFACTURING FEATURES

• Ventilation box with 30 mm aluminum profile structure, nylon corners, galvanized sandwich panels with internal insulation rockwool (25mm thickness) class A1 (non-combustible) of 90kg/m3 density. All panels are equipped with "fastening system" for the quick assembly and disassembly whenever required, either for cleaning, maintenance or exchanging of panels.
• Centrifugal fan with motor coupled directly to the impeller.
• Circular suction mouth to facilitate duct connection. Open lateral drive.
• Standard squirrel cage asynchronous motor, with IP-55 protection and class F insulation. Voltages 230/400V 50Hz for three-phase motors.
• Backward curved single inlet impeller of high performance with self-cleaning system made of steel. Balanced statically and dynamically at origin.
• Interchangeable panels.
• Motor B5 construction located outside the air flow, on the back of the box there is a grid to allow the entry of air to facilitate the cooling of the engine.

FREQUENCY SPEED CONTROLLER

MANUFACTURING FEATURES

• Specially designed for speed frequency control in ventilation applications.
• Ultra compact, simple operation and wide range of functions.

*Dial panel incorporated. Optional EMC filter.

Certifications: CE/UL/CSA/EN/GOST/CCC.

Protection index IP20.

The selection of SFC frequency drive speed controller must be made based on the maximum intensity absorbed by the fan to be regulated. The powers (kW) and the intensity for constant load refer to the normal duty (150% overload for 60 seconds). The intensity for quadratic load admits an overload of 110% during 60s.

SFC 230: Entrance 230V I, exit 230V III
SFC 400: Entrance 400V III, exit 400V III

EMC filter incorporated for models from 47A (included)
