Product Overview
A centrifugal box inline fan is installed within a duct system to pull or push exhaust air through connected ductwork. The CHA square inline fan is built for commercial and extractive industry applications where reliable ducted ventilation is required.
The catalog describes a compact square design, full molded and fully welded structure, galvanized or stainless housing options, aluminum alloy wheel, and direct connection with standard diameter circular ducting.
It is especially useful for restaurant grease exhaust, commercial kitchen exhaust, factory exhaust, low-noise industrial ventilation, and MEP project supply where discharge position, isolators, and maintenance access matter.
Key features for ducted inline exhaust
A square inline fan range for ducted commercial and industrial extraction where low-noise operation, side discharge, installation flexibility, and service access are important.
Technical specifications
Final selection depends on airflow, static pressure, grease load, duct route, discharge position, voltage, mounting method, and site conditions.
Inline fan applications
Use CHA centrifugal box inline fans for ducted exhaust where the fan is installed in line with circular ducting and selected by airflow, pressure, and discharge direction.
