9BMB24P2K01 Sanyo Denki 24V 1.62A DC Centrifugal Blower

Description

The Sanyo Denki 9BMB24P2K01 is an ultra-high-performance industrial DC Centrifugal Blower with dimensions of 97 x 94 x 33 mm. Driven by a high-torque Brushless DC Motor, this San Ace 97BMB series model is engineered as an extreme-pressure thermal solution operating on a nominal 24 VDC. It delivers a powerful maximum airflow of 54.7 CFM (93.0 m³/h) at a high rated speed of 8400 RPM. With a substantial rated current of 1.62 A and a power input of 38.88 W, it is specifically designed to overcome extreme airflow resistance in high-density 1U/2U server blades and telecommunications rectifiers. This 4-wire version features a premium dual-ball bearing system and a specialized centrifugal impeller capable of generating a massive static pressure of 4.10 inAq (1020 Pa). Equipped with both PWM speed control and tacho signal output, the 9BMB24P2K01 provides intelligent, high-intensity cooling for mission-critical infrastructure where standard blowers fail to provide sufficient air penetration.

Application
The 9BMB24P2K01 is primarily utilized as a specialized high-intensity cooling solution for high-density 1U/2U server chassis, core networking switches, and 24V telecommunications power modules. Its 1.62 A high-power motor is essential for these applications, generating an extreme static pressure of 4.10 inAq to force air through tightly packed internal components and sophisticated heat pipe arrays. The 4-wire PWM interface allows the system to scale its cooling performance from a quiet idle to a full 8400 RPM output during peak processing loads. This model is a mission-critical component in industrial medical scanners and high-wattage power rectifiers where directional airflow and extreme pressure reliability are required to prevent thermal throttling of high-heat-generating power components in space-constrained environments.
