HKA 315 CENTRIFUGAL (C-386)

The HKA Series Smoke Exhaust and Supply Blower is a high-performance centrifugal fan designed to extract hot smoke, fumes, and contaminated air in emergency or industrial ventilation systems.
It is ideal for car parks, commercial kitchens, factories, paint booths, and industrial halls, where reliable air movement under high temperature or heavy-duty operation is required.

The unit ensures high efficiency, stable performance, and low vibration while operating safely even at elevated temperatures.
