Exhaust centrifugal fans VENTS VCN EC series

• Exhaust ventilation systems for commercial, office and other public or industrial premises for extraction of air with temperatures up to 40 °C.

• Direct air exhaust is provided.

• Steel casing with polymeric coating ensures motor protection against direct humidity exposure in case of the unit outdoor mounting.

• The fan bottom has a bird and rodent proof guard. Air is exhausted vertically down.

The motor is protected against direct ingress of moisture and foreign objects

• The units are equipped with high-efficient EC motors with an external rotor and an impeller with backward curved blades.
• These state-of-the-art motors offer the very best in energy efficiency today.
• EC motors are characterised with high performance and optimum control across the entire speed range.
• In addition to that, the efficiency of the electronically commutated motor reaches very impressive levels of up to 90 %.

• The fan is controlled with the external control signal 0-10 V (capacity control is performed depending on the required level of productivity, temperature, humidity, pressure and other parameters).
• Should the control value factor get changed, the EC motor changes its speed and the fan boosts as much air flow to the ventilation system as required.

• Maximum fan speed does not depend on the available current frequency and is suitable for operation both at 50 and 60 Hz.
• Several fans can be integrated into a single computer-driven control system.
• Custom designed software provides high accuracy control of the fans integrated into a network.

• The fan is designed for outdoor surface wall mounting and connection to round duct of the respective diameter.
• The fan is powered through the external terminals.

• Electric connection and mounting shall be performed in compliance with the manual and wiring diagram provided in unit operation manual.
