What should be considered for warehouse ventilation?

What should be considered for warehouse ventilation?(1) Check whether stored goods are flammable or explosive. For example, in paint warehouses, explosion-proof series fans must be selected. (2) Based on noise requirements, choose either roof ventilators or eco-friendly centrifugal fans. (3) Based on the required ventilation volume for warehouse air, select either conventional axial fans SF or exhaust fans FA. Kitchen Exhaust (1) For kitchens venting fumes directly indoors (i.e., exhaust outlets on interior walls), select SF axial fans or FA exhaust fans based on fume volume. (2) Centrifugal fans are strongly recommended for high-fume kitchens requiring long ducting with bends. This is because centrifugal fans deliver higher pressure than axial fans, prevent fumes from entering the motor, and simplify motor maintenance and replacement. (3) For kitchens with extremely heavy fumes, combining the above two solutions is recommended for optimal results. Venue Ventilation Conventional fans are unsuitable for ventilating venues such as hotels, teahouses, cafes, card rooms, and karaoke lounges. (1) For ventilating small rooms connected to central ductwork, choose compact axial fans featuring small dimensions, plastic or aluminum exteriors, low noise, and high airflow. (2) Where airflow and noise levels demand strict control, fan enclosures are an excellent choice. These units feature internal sound-absorbing cotton and deliver significant noise reduction when connected to central ductwork externally. (3) For indoor air circulation in gyms, high-capacity industrial fans must be selected instead of SF rear-mounted axial fans. This is crucial for both aesthetic and safety considerations.
