Qg030-148/12 Tangential Blowers

Product Description

The QG030-148/12 Tangential Blower is a compact crossflow cooling fan designed for uniform air distribution and efficient thermal management in tight industrial spaces. It is widely used in HVAC systems, air curtains, electrical cabinets, heating equipment, telecom devices, and automation systems where low-profile, wide-area airflow is required.

Its tangential design allows air to move evenly across the entire length of the blower, making it ideal for applications needing stable cooling rather than focused airflow. Built with a slim aluminum housing and precision ball bearing motor, it ensures long service life, low vibration, and consistent performance.
