The PWM static pressure fans are engineered with a wider intake and exhaust fan frame to boost overall airflow and pressure. Winglet fan blade provides minimal air resistance to boost overall airflow.
The AC cross flow fan consists of AC motor with external rotor and metal impeller, and has the following features: compact construction, light weight, high speed, high air flow, low noise & vibration and easy mounting etc.
12-volt brushless cross flow fan is made of PBT material and has high speed (5500 RPM), but the noise generated by operation is low, so it can be safely used in sports equipment.
