What Buyers Ask Before Inquiry
Not recommended. Without an exhaust outlet, air cannot circulate smoothly. Internal static pressure will rise sharply and actual airflow will drop greatly, resulting in poor cooling effect. We suggest matching intake fan and exhaust grille as a set.
It depends on the working environment. In dusty workshops, clean the filter sponge every 1u20132 months and replace it every 6u201312 months. Clogged filter will reduce airflow and cause overheating of cabinet components. The louver cover can be opened quickly for maintenance.
Yes, it can be mounted reversely as an exhaust fan. But note that the filter sponge will then trap dust inside the cabinet. For dust prevention, the fan should be used as an air inlet, and the passive grille as air outlet.
