How to choose the right HEPA exhaust unit for your specific industry?
How to choose the right HEPA exhaust unit for your specific industry?Consider industry pollutant characteristics.Type of pollutants: If the industry produces toxic and harmful gases, like the chemical industry, it is necessary to choose an exhaust unit that can withstand strong corrosion and high wind pressure, such as the centrifugal HEPA exhaust unit, which can overcome the resistance of the purification equipment and send the exhaust gas to the treatment device. If dust is produced, such as metal dust in the machining industry, the axial flow HEPA exhaust unit can quickly discharge dust due to its large air volume. Pollutant concentration: Industries with high concentrations of pollutants, such as some chemical production workshops, need ventilation equipment with large exhaust air volume and continuous and stable operation to ensure that pollutants can be discharged in time and not accumulate in the workshop. Combined with industry spatial layout Space openness: In large, open industrial workshops, such as machining workshops, textile factories, etc., the axial flow efficient exhaust unit is convenient to install, can be flexibly arranged according to the layout of the workshop, and can quickly cover a large area of space for exhaust. In some places with compact space and high indoor layout requirements, such as precision instrument manufacturing factories, rooftop HEPA exhaust units do not occupy indoor space and are a better choice. Indoor structure complexity: If there are more partitions and complex pipeline lines in the room, the centrifugal HEPA exhaust unit has more advantages in the layout of the air duct, and it can collect and discharge the dirty air in each area through a reasonable design of the air duct. According to the air quality requirements of the industry Cleanliness requirements: The electronic industrial chip manufacturing workshop has very high requirements for air cleanliness, and it is necessary to maintain a micro-positive pressure environment to prevent external pollutants from entering. The centrifugal HEPA exhaust unit can accurately control the air volume to meet this demand. To ensure the quality and safety of food, no odor, and excessive water vapor can affect the food, the rooftop HEPA exhaust unit can discharge odor and water vapor in time. Temperature and humidity requirements: greenhouses and farms in the agricultural field have strict requirements for temperature and humidity. The axial flow HEPA exhaust unit can adjust the ventilation volume in time according to the temperature and humidity changes, discharge hot and humid air and harmful gases, introduce fresh air, and create a suitable environment. Focus on equipment operating costs and maintenance difficulties. Operating costs: Different types of exhaust units have different energy consumption, which should be considered in combination with the use time and electricity cost of the industry. For example, in the commercial field of large shopping malls, office buildings, and other places that run for a long time, it is necessary to choose relatively low energy consumption equipment to reduce operating costs. Maintenance difficulty: Some industries have strong production continuity, such as the chemical industry, food processing, etc., and can not be frequently shut down for equipment maintenance. Therefore, it is necessary to choose an efficient exhaust unit that is easy to maintain and easy to replace parts to ensure stable operation of the equipment and reduce production interruption caused by maintenance. |
