Reversible Flow Fan that can blow air in 2 opposite directions - φ136 × 28 mm - Sanyo Denki

November 2, 2021

 

SANYO DENKI Develops φ136 × 28 mm Reversible Flow Fan with the Industry's Highest Airflow and Static Pressure That Can Blow Air in Two Opposite Directions

SANYO DENKI CO., LTD. has developed and launched the φ136 × 28 mm San Ace 136RF 9RFA type Reversible Flow Fan that has the highest airflow and static pressure in the industry.(1)
This fan is ideal for home ventilation systems and other applications that require two-way blowing fans.

Features

1. High Airflow and High Static Pressure

This fan delivers a maximum airflow of 2.10 m3/min and a maximum static pressure of 285 Pa,(2) both of which are leading in the industry.(1)
Compared to our current model,(3) the maximum static pressure has increased by approximately 2.8 times.

2. Fewer Fans Required

The fan's speed and blowing direction can be freely controlled by a PWM signal.
By replacing multiple conventional fans with a single unit, this fan can contribute to cost reduction and space saving.
Moreover, noise reduction or high efficiency can also be achieved by appropriately controlling fan speed.

3. Same Level of Blowing Performance in Either Direction

Almost equivalent airflow and static pressure performance can be obtained in either blowing direction.
This eliminates the need to take the performance difference between two blowing directions into account in designing systems.

(1) Based on our own research as of August 31, 2021, among equally-sized industrial two-way fans on the market.

(2) The values are for models 9RFA1312P3G001 and 9RFA1324P3G001 when blowing in the forward direction.

(3) Current model: φ136 × 28 mm San Ace 136RF 9RF type Reversible Flow Fan (model: 9RF1312P3H001)
