Location of use: Lower spray nozzles are usually used in places with suspended ceilings, while upper spray nozzles are used in places without suspended ceilings.
Spray direction: The water flow from the lower spray nozzle mainly sprays downwards, while the water flow from the upper spray nozzle sprays upwards, with about 85% of the water flowing downwards.
Installation height: The installation height of the upper spray nozzle is generally 75mm-150mm above the top.
Replacement restriction: The upper and lower spray nozzles cannot be replaced casually because their working principles and applicable environments are different. Incorrect replacement will directly affect the fire extinguishing effect.
These differences are crucial for fire safety, ensuring the correct type of nozzle can effectively improve fire extinguishing efficiency.
