A Treated Fresh Air Unit (TFA) is an HVAC ventilation system designed to supply filtered, cooled and humidity-controlled fresh outdoor air into indoor spaces. It removes dust, pollutants, excess moisture and other airborne contaminants before delivering clean air to the occupied area.
TFA units help maintain positive indoor pressure, improve indoor air quality and reduce the fresh-air load on the main air-conditioning system. These units can be customised with pre-filters, fine filters, cooling coils, heating coils, centrifugal or plug fans and advanced control systems. They are widely used in hospitals, pharmaceutical facilities, cleanrooms, offices, hotels, shopping centres, laboratories and industrial buildings.
