High-Performance 133 DC Double Inlet Blower for Industrial Cooling Applications

Introduction

In modern industrial and commercial systems, efficient airflow and precise thermal management are critical to performance and reliability. From HVAC systems to electronics cooling and filtration equipment, selecting the right blower can significantly impact energy efficiency, noise levels, and lifespan.

The PB2ED133LB2M-A 133 DC Double Inlet Blower from APS Limited is engineered to meet these demands, combining a 48V brushless DC motor, dual-inlet aluminum impeller, and advanced speed control options for superior cooling performance.

What Is a 133 DC Double Inlet Blower?

A 133 DC double inlet blower is designed to draw air from two inlets, allowing for higher airflow and increased static pressure compared to single-inlet designs. This configuration is particularly effective in applications where space is limited but consistent airflow is essential.

The PB2ED133LB2M-A features a one-piece, 38-blade aluminum impeller, ensuring balanced airflow, reduced vibration, and long-term operational stability.
