The installation of exhaust fans must be reliable and firm, with a distance of at least 2.3m from the ground;
The distance between the exhaust fan and the roof must be at least 5CM;
Remember not to install the ceiling mounted system in areas with high levels of oil fumes and dust, and keep it away from high temperature sources;
The wall mounted fan can be used for ventilation and ventilation in various places, as well as for smoking oil fumes;
Remind everyone that when using sockets for power supply, the power cord should be connected to a plug that meets safety standards;
The yellow and green dual color wires in the power cord of the exhaust fan must be grounded;
The power supply of the exhaust fan should be connected to a full pole switch as much as possible;
Inspection holes must be installed at the top of the ceiling;
Reminder everyone to avoid gas backflow through open airways and other pyrotechnic equipment channels;
Do not bend the pipeline into a V-shaped or bell shaped shape to obstruct air circulation;
There must be air intakes in the room to ensure fresh air enters;
Do not pour water onto the body of the exhaust fan during operation;

A ventilation fan is composed of auxiliary components such as an electric motor, fan blades, air frame, and panel. It is generally installed in the kitchen or bathroom and is mainly used to remove indoor polluted air, inhale fresh air, and achieve the purpose of regulating temperature and humidity. The ventilation fan is driven by an electric motor to rotate the blades and drive the airflow. There are three types of ventilation methods: exhaust, suction, and combined. The exhaust type enters the air from the natural intake and expels polluted air through a ventilation fan. The suction type draws in fresh air through a ventilation fan and expels polluted air from the natural exhaust port. The combination of intake and exhaust is completed by a ventilation fan.
