Do you need to spray the kitchen fume exhaust pipe in the hotel?

Yes, water vapor can filter and adsorb the oil fume, which is good for filtering the oil fume and reducing the oil fume sucked into the air duct and fan, which is beneficial to environmental protection, the service life of your equipment and future maintenance. If there is no spraying equipment, the oil fume will directly enter the air duct and fan and then be discharged to the outside, which is not environmentally friendly and will do great damage to the equipment, and future maintenance will be a hassle!
