High Static Pressure and High Airflow
This blower delivers a maximum static pressure of 540 Pa and a maximum airflow of
1.09 m
3
/min.*
Blowers can send out straight airflow with high static pressure,
making them suitable for localized and spot cooling applications.
Water and Dust Resistance
Its IP68-rated** water and dust protection ensures stable fan operation even in harsh
environments.
High Energy Efficiency and Low Noise
The PWM control function enables the control of fan speed, contributing to lowering
noise and improving energy efficiency of devices.
* These values are for models 9W1BM12P2H001 and 9W1BM24P2H001
** The degree of protection (IP code) is defined by IEC 60529 (International Electrotechnical Commission).
IP68:
・
Completely protected against dust
・
Protected against submersion in water
