Product Overview
The steel circular inline duct fan is a compact centrifugal inline exhaust fan designed for direct connection with standard round ducting. The TSK model series uses a backward impeller with axial outlet airflow for practical duct ventilation layouts.
The fan body uses galvanized steel catalog construction, an AC single-phase asynchronous external rotor motor, corrosion-resistant baked powder coating, and a compact format that supports easy installation and repair.
It is suitable for stairwell pressurization, hydroponic grow room ventilation, low-noise industrial applications, agricultural areas, factories, and building ventilation projects where a small circular inline duct fan is required.
