The VN3 series linear actuator is specifically designed for ventilation applications to help quickly remove smoke, heat, and toxic gases from buildings in the event of a fire. It is also engineered to support a reduced smoke layer in the lower parts of a room. The VN3 is constructed with high-quality aluminum, making it ideal for applications like greenhouses. The VN3 has a higher load capacity than the VN2, and is currently equipped with either a 12V or 24V DC motor.
