The APF series consists of air purification cabinet-type units designed for both supply and exhaust applications. These fans offer benefits such as a compact size, straightforward installation and maintenance, and a logical structural layout. Each unit comes equipped with full-effect purification filters, including primary, medium, and high-efficiency options. This series is well-suited for air supply, ventilation, and as supporting equipment in hospitals, high-end hotels, civil buildings, department stores, dance halls, cinemas, gymnasiums, and similar venues.
