Its robust steel housing with polymer coating, single-phase AC motor with ball bearings and integrated thermal protection make it suitable for greenhouses, warehouses, production premises and other professional ventilation installations.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eVENTS VKF 4E 450\u003c\/strong\u003e is part of the industrial series of axial fans \u003cstrong\u003eVENTS OV \/ OVK \/ VKF\u003c\/strong\u003e. The main difference of the VKF is its construction designed for \u003cstrong\u003edirect installation in a ventilation duct\u003c\/strong\u003e, allowing it to be easily integrated into supply and extract ventilation systems.\u003c\/p\u003e\n\n\u003cp\u003eThe fan is suitable for applications where it is necessary to move \u003cstrong\u003ea large volume of air at relatively low system resistance\u003c\/strong\u003e. At a 50 Hz power supply, the model reaches a maximum airflow of \u003cstrong\u003e4680 m³\/h\u003c\/strong\u003e, while the motor operates at approximately \u003cstrong\u003e1350 rpm\u003c\/strong\u003e and consumes \u003cstrong\u003e250 W\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eThe construction has been developed with an emphasis on reliability during continuous operation. The housing and impeller are made of \u003cstrong\u003esteel with a durable polymer coating\u003c\/strong\u003e, providing mechanical strength and additional protection for the metal surfaces.\u003c\/p\u003e\n\n\u003cp\u003eThe \u003cstrong\u003e4E\u003c\/strong\u003e model uses a \u003cstrong\u003efour-pole single-phase asynchronous AC motor with an external rotor\u003c\/strong\u003e. The motor has integrated thermal-overload protection, and the ball bearings are designed for a long service life. For this series, the manufacturer specifies a bearing design life of \u003cstrong\u003eat least 40 000 operating hours\u003c\/strong\u003e.\u003c\/p\u003e\n\n\u003cp\u003eAnother important advantage is the possibility of \u003cstrong\u003espeed control\u003c\/strong\u003e.
