Zařízení je sestaveno z provětrávacích trámců ve tvaru obrácených žlabů, které jsou na jedné straně kotveny do výsypky nebo stěny sila a druhé konce jsou ve střední části sila podepřeny na nosné konstrukci. Středové konce provětrávacích trámců jsou zastřešeny stříškou, pod níž se vytvoří volný prostor, který slouží jednak pro rozvod vzduchu do jednotlivých větracích žlabů a dále též k prostupu vzduchu do skladovaných sypkých materiálů. Přívod větracího vzduchu je proveden z vnějšího prostoru jedním přívodem pod jeden nebo dva větrací trámce.
