DC centrifugal fans cut acoustic noise levels

A family of DC centrifugal fans that in typical high performance cooling applications consume 13% less power than competitive products is currently available at EAO. The fans offer significantly reduced acoustic noise levels. Manufactured by Sanyo Denki, the San Ace C175 9TGA DC centrifugal cooling fans measure just 175mm x 69mm.

The 48VDC version delivers 1100Pa (max) static pressure with a maximum airflow of 1056m3/hour (622 CFM) whilst the 24VDC version produces 830Pa (max) static pressure and delivers a maximum airflow of 918m3/hour (541CFM).

Both fans features a sound pressure level (SPL) rating that is 3dB(A) lower than competitive products.

According to Robert Davies EAO UK Marketing Manager, Sanyo Denki has engineered the San Ace C175 9TGA cooling fans to operate efficiently and reliably in even the most demanding applications.

"A rugged dual ball bearing construction ensures reliable long term operation of 60,000 hours at 40oC and 40,000 hours at 60oC, Davies explained. "And with an operating temperature range of -20 to +70oC these fans exceed the requirements of numerous modern applications including mobile telecoms cabinets, heat exchangers, large-scale energy storage systems and fuel cells."

The cooling fans are part of an extensive Sanyo Denki centrifugal fan range supplied and supported by EAO Ltd. The company's product portfolio also includes DC centrifugal fans in100, 133, 150, 175, 221, 225 and 270mm diameters, available in both standard and IP55 rated versions.
