The AQX air-handling units feature: basic modular series developed on 32 standard sizes with constant coverage from 2.2 m/s to 2.52 m/s; the high level of engineering of the AQX series allows, along with the 32 standard sizes, to set different frontal dimensions in order to meet specific size requirements for construction sites and handling needs, with a 50 mm pitch both in terms of height and depth; aluminium alloy frame with an exclusive design; thermal cut as standard on sections and joints between sections; concealed intermediate sections; thermally cut sandwich buffer panels, 50mm thick with thermoacoustic insulation made with injected polyurethane (40 kg/m³) or mineral wool (90 kg/m³); the internal and external sheet metal of the panels can be selected among 7 types of material with different thicknesses; handles for inspection doors that can also be opened from the inside; absolutely smooth internal surfaces to minimise dust deposits and make cleaning and disinfection easier; antivibration bellow supplied as standard on the fans intake; the AQX units can be equipped with a vast array of filtering solutions starting from simple G2 undulated synthetic filter cells, along with a wide range of rigid pocket cells, absolute filters, automatic filters, electrostatic and active carbon filters with high and extremely high efficiency levels;
