Size the AHU on airflow and system static, not a catalogue photo. First: m³/h for the office, plant or hall, duct length and pressure drop, filters (Tashkent dust is real) and whether supply air needs heat or cooling. Oversizing without a network gives grille whistle and wasted power.
Sections: fan, filter, heating or cooling coil, sometimes a recuperator, silencer, controls. At +40°C, untempered supply becomes staff complaints — that is heating/cooling plant, not a fan accessory.
Check plant-room or roof space, filter access, spare pressure for dirty filters and noise next to offices. A cheap weak fan chokes on real fittings and dampers.
Aurum Prodest calculates the network, fabricates ducts in-house and packages the AHU as turnkey install: one contractor for the unit, ducts and commissioning.
