SANYO DENKI Releases 40 × 40 × 56 mm Counter Rotating Fan
With the highest static pressure in the industry

August 18, 2020

SANYO DENKI CO., LTD. has developed and launched the San Ace 40 9CRJ type 40 × 40 × 56 mm Counter Rotating Fan that features the highest static pressure in the industry.*
This fan is suitable for cooling 1U servers, switching power supplies, and communications equipment.
It also comes with the PWM control function to control the fan speed.

San Ace 40


1. High Static Pressure and High Airflow

This fan delivers a maximum static pressure of 2400 Pa and a maximum airflow of 1.06 m3/min.
Compared with our current model,** the maximum static pressure has increased by 1.4 times and the maximum airflow has increased by 1.1 times.
This fan can efficiently cool high-density equipment that is hard to ventilate, contributing to system downsizing.

2. Energy Saving

Power consumption has been reduced by approximately 20% compared with the current model.**
The PWM control function enables the control of fan speed, contributing to energy saving.

* Based on our own research as of August 18, 2020, conducted among equally-sized axial DC fans on the market.

** San Ace 40 9CRH type 40 × 40 × 56 mm Counter Rotating Fan (model: 9CRH0412P5J001).
