Dimensions (unit: mm) (With ribs) 9WPA type 4-4.50.3 800.5 25.20.5 Mounting hole 71.50.3 (4) (4) Splash Proof Fan Lead wire Features AWG 26 UL 1430 High Airflow and High Static Pressure +50 3 This fan delivers a maximum airflow of 2.32 m /min and a maximum static pressure 300 0 of 210 Pa. (1) Compared with the current models, the maximum airflow has increased by 1.5 times and maximum static pressure has increased by 2.6 times. (10) Water and Dust Resistance (2) These fans have IP68-rated water and dust protection. They maintain stable operation even in harsh environments. Low Noise and High Energy Efficiency Rotating direction Airow direction The PWM control function enables the control of fan speed, contributing to lowering noise and improving energy efficiency of devices. (1) Current models: San Ace 80 9WP type 80 80 25 mm DC Fan (model nos. 9WP0812G401). (2) The degree of protection (IP code) is defined by IEC 60529 (International Electrotechnical Commission). Reference Dimensions of Mounting Holes and Vent Opening (unit: mm) IP68: Completely protected against dust Protected against submersion in water Inlet side, Outlet side IPX8 Requirements When the power is off, the fan is submerged in water pressurized to the equivalent of 2 meters for 60 minutes. Then it s run for 15 minutes at the rated voltage in free-air. During the test, there shall be no 71.50.3 reduction in dielectric strength or fan characteristics. 4-4.5 80 80 25 mm Specifications The models listed below have ribs and pulse sensors with PWM control function.
