How does the Dawang large safety fan affect airflow?

    The airflow and high volume of the King Large Safety Fan is one of the most effective ways to keep employees and guests comfortable in your space. The airflow formed by the fan blades of the King safety fan pushes to the ground, and beyond the diameter of the King fan, the airflow is transformed into horizontal air movement. Based on ASHRAE 55 thermal comfort calculations, the King Large Safety Fan provides a large area of ​​comfortable airflow. In addition, Dawang large industrial safety fans feature variable speed control, allowing users to adjust airflow to provide the optimum cooling effect required.

    Fresh air is often not evenly distributed throughout the space. For example, one of the common air distribution configurations for HVAC systems is a supply with overhead return air. In common heating applications, this configuration results in significant stratification of heated supply air and indoor air, preventing fresh air from circulating to occupant heights. According to ASHRAE 62.1 standard, the ventilation rate is required to be increased by 20% in order to provide the necessary fresh air for the occupants of the room. However, in a space with a large fan installed, the air layers can be well integrated, eliminating stratification and supplying fresh air to the level required by the occupants.

    In a naturally ventilated space, fresh air is passively distributed throughout the space, so stagnant zones may develop in localized areas, resulting in poor air quality and the accumulation of pollutants. King large safety fans disperse these stagnant zones and increase the circulation of fresh air, evenly distributing it throughout the space, fully improving indoor air quality.

To what extent will the increased air flow of the King Large Safety Fan improve the ventilation of the space?

    CFD analysis of industrial spaces by King Large Safety Fans shows that King Large Safety Fans provide measurable benefits. For example, a 24 ft (7.3M) large safety fan can directly push the airflow over an area of ​​about 1500 square meters, and horizontally, the large king safety fan can push the air flow to a larger area (depending on the installation height, ground obstacles, fan model, etc.). If you need a customized professional ventilation solution to improve airflow in your space, please consult the Dawang Large Safety Fan Sales Hotline on 400 086 9230.

Should a large industrial fan be used during public health events such as flu season?

    There are many variables for every facility and application, and it is impossible to determine whether increased air velocity has a significant impact on health without a thorough study of the data for each case. Dawang large industrial safety fans put the safety and health of customers first, in addition to complying with the design standards and concepts specified by ASHRAE, they also follow the guidelines outlined in the Chinese Center for Disease Control and Prevention (CDC) and WHO.

    Using the King Large Safety Fan can dilute to reduce the concentration of airborne pathogens, increase ventilation rates, and provide higher dilution capacity, thereby reducing the risk of potential infection.

King large safety fan recommends the following:
    In naturally ventilated spaces, increase the intake of ventilation (outdoor air) as much as possible, and develop good respiratory hygiene habits. Cover your cough or sneeze with your elbow or a tissue and wash your hands regularly. Clean and disinfect frequently touched objects and surfaces, such as workstations, keyboards, phones, handrails, and doorknobs.
