FIELD: transport.
SUBSTANCE: invention relates to aircraft air conditioning. Device for fast equalising or air pressure between aircraft fuselage separated compartments subjected to air pressure difference comprises one through hole on fuselage, pressure reduction gate partially closing said hole, and opening mechanism. Said mechanism unlocks aforesaid gate for it to move into open position whereat aforesaid through hole is, in fact, open when critical pressure difference is exceeded. Aforesaid gate comprises articulated parts that pass partially into cabin floor area and is integrated with aircraft passenger cabin side sheathing.
