The 422JN is a 12VDC standard or basic speed Axial Fan with speed signal, Go/No-go alarm, external temperature sensor, PWM control input, moisture protection, protection against salt spray fog, very pressure-insensitive characteristic curve for high air flow at high back pressure. Low operating noise at high back pressure, ball bearing and wire leaded power connection. Fibreglass-reinforced plastic (PBT) housing and fibreglass-reinforced plastic (PA) impeller. Counter-clockwise direction of rotation looking at rotor, air exhaust over bars direction of air flow with single strands 28AWG, UL 1061 leads, jet characteristic/rigid curve. The DC axial compact fan is suitable for high air performance with moderate pressure build-up. The flow of air through the fan blades is parallel to the rotation axis.
