Can you put something else in the main ventilation duct of the hotel?

You can't put anything in the main ventilation duct of the hotel. According to the relevant public information, the main oil fume duct of the hotel is an important passage for the hotel kitchen to discharge oil fume and waste gas. Under normal circumstances, it should be kept open and no other items can be placed inside. This is because the accumulation of sundries or articles in the air duct may affect the normal work of the air duct, increase the difficulty of cleaning, and even cause harm to oil smoke emission, affecting the environmental sanitation and safety of the hotel.
