Fan selection in industrial processes does not only consist of determining the desired flow rate and pressure values. Chemical structure, corrosive effect, temperature, humidity, particle content, gas density (specific gravity) and operating characteristics of the process of the gas to be transported; It directly affects the entire engineering process, from the material of the fan to its aerodynamic design.<\/p>\n

Especially acid vapors, alkaline gases and other\u00a0corrosive<\/a>\u00a0in processes involving chemicals, standard metal fans can corrode in a short time. This not only shortens equipment life; It can also cause unplanned downtime, increased maintenance costs and reduced process reliability.<\/p>\n

However, choosing the right fan does not only mean determining the appropriate material. The flow rate, static pressure, temperature, gas density, chemical composition and system resistance of the gas to be transported in the process should be evaluated together. Especially the specific gravity of the gas; It is an important design parameter that directly affects the required fan power, engine selection, impeller load and performance curves. Two different gases with the same volumetric flow rate may require completely different fan designs due to their physical properties.<\/p>\n

In this article\u00a0plastic industrial radial fans<\/a>\u00a0we will consider in which sectors and processes it is preferred, in which applications it stands out, and the basic engineering criteria that should be taken into account in fan selection according to process conditions.<\/p>\n

1 . What is a Plastic Fan?<\/h2>\n

Plastic industrial radial fan; It is an industrial process fan produced from high chemical-resistant polymer materials suitable for application for the safe transportation of corrosive, chemical and aggressive process gases. It offers a long-lasting and reliable solution with the right material and engineering design in applications where the service life of metal fans may be limited due to corrosion. For this reason, plastic industrial radial fans; It is widely used in industrial processes where corrosive gases are present, such as chemistry, galvanization, metal plating, acid processes, gas washing systems (scrubber), pharmaceuticals, fertilizers, battery production and wastewater treatment.<\/p>\n

Plastic fan<\/a>\u00a0the most important criterion in its design is not only the material of the fan. The chemical composition, temperature, gas density (specific gravity), humidity, particle content, flow rate, total pressure and process operating conditions of the gas to be transported should be evaluated together. Two different processes operating at the same flow rate may require completely different fan design, engine power and material selection due to the physical and chemical properties of the gas.<\/p>\n

Not a single plastic material is suitable for every corrosive gas. Material of fan body, impeller and other process-contact components; It should be determined according to the chemical properties, temperature and process conditions of the gas to be transported, taking into account engineering calculations and chemical resistance data.<\/p>\n

Why Are Plastic Industrial Radial Fans Preferred?<\/h3>\n
    \n
  • High Chemical Resistance in Corrosive Environments<\/strong><\/li>\n<\/ul>\n

      \n
    • Engineering Design According to Process Conditions<\/strong><\/li>\n<\/ul>\n

      The flow rate, total pressure, gas density (specific gravity), temperature and system resistance required by each process are different. Therefore, fan selection should be made not only based on catalog values; It should be done taking into account process data, performance curves and operating conditions.<\/p>\n

        \n
      • Low Operation and Maintenance Cost<\/strong><\/li>\n<\/ul>\n

        Plastic radial fans designed in accordance with process conditions and produced with the right material; It contributes to operating continuity by reducing the risk of corrosion-induced maintenance, part replacement and unplanned downtime.<\/p>\n

        2. Metal vs. Plastic Fan: Which is Right for Your Facility?<\/h2>\n

        Choosing a galvanized or stainless fan just by looking at the initial investment cost is the biggest mistake made in industries with a risk of corrosion. When the Total Cost of Ownership (TCO) is analyzed, it becomes clear how plastic fans protect your operating budget.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n

        3. Use of Industrial Plastic Radial Fan in Galvanization and Metal Surface Treatment Plants<\/h2>\n

        Chemicals used in galvanizing, pickling (acidification), metal plating and similar surface treatment processes can cause the formation of highly corrosive gases and vapors. Therefore, the fans used in these processes should not only provide the required flow rate and pressure; It should also be designed to withstand the chemical structure of the transported gas and process conditions for a long time.<\/p>\n

        Especially in applications where chemicals such as hydrochloric acid (HCl), sulfuric acid (H \u2082SO\u2084), nitric acid (HNO\u2083) and similar chemicals are present, choosing the wrong material can significantly shorten fan life. However, choosing the right fan is not limited to chemical resistance. The temperature, specific gravity, humidity, particle content, flow rate, total static pressure requirement and system resistance of the gas should be evaluated together.<\/p>\n

        In galvanizing and metal surface treatment plants, industrial radial fans are mainly used in the following processes:<\/p>\n

          \n
        • Pickling (Acidification) lines<\/li>\n
        • Acid tank suction systems<\/li>\n
        • Rinsing and process tanks<\/li>\n
        • Chemical preparation and dosing units<\/li>\n
        • Gas flushing (Scrubber) systems<\/li>\n
        • Chemical exhaust and flue gas transfer lines<\/li>\n<\/ul>\n

          Body and impeller material of the fan; It should be determined according to the chemical composition, temperature and operating conditions of the process gas. Different materials such as PP, PE, PVC, PVDF, FRP or antistatic polymers should be evaluated so that each is suitable for different process conditions. The assumption that a single material is suitable for all chemicals and all operating conditions is not correct.<\/p>\n

          Fan Selection in Pickling (Acidification) Lines<\/strong><\/h3>\n

          Different acid solutions, especially hydrochloric acid (HCl), can be used in pickling processes. Flow rate of gas absorbed from tanks, channel geometry, hood design, scrubber pressure losses and system resistance; It directly affects the operating point of the fan. Therefore, it is not enough to choose a fan based solely on chemical resistance.<\/p>\n

          Fan design in such applications; Based on process data, the required air flow rate, total static pressure, gas density (specific gravity), engine power and material selection should be evaluated together.<\/p>\n

          4. Industrial Radial Fan Applications in Chemical Plants and Acid Processes<\/h2>\n

          In chemical plants, fans are used not only for gas evacuation purposes; It is an integral part of the process to ensure process safety, emission control and safe operation of equipment. Controlled transport of gases formed in many units such as reactors, storage tanks, mixers, dosing systems, evaporators and the like is critical to process continuity.<\/p>\n

          In these applications, only the required air flow rate should not be taken into account when selecting the fan. The chemical composition of the gas to be transported, its temperature, gas density (specific gravity), humidity, particle content, explosive environment class (ATEX), system resistance and operating characteristics of the process should be evaluated together. All of these parameters directly affect fan performance, engine power and material selection.<\/p>\n

          In chemical plants, industrial radial fans are commonly used in the following processes:<\/p>\n

            \n
          • Reactor exhaust systems<\/li>\n
          • Chemical storage tanks<\/li>\n
          • Acid and alkali tank ventilation systems<\/li>\n
          • Solvent transfer and storage areas<\/li>\n
          • Gas flushing (Scrubber) systems<\/li>\n
          • Evaporation and concentration processes<\/li>\n
          • Chemical filling and dosing units<\/li>\n
          • Flue gas purification systems<\/li>\n<\/ul>\n

            Fan Selection in Acid Processes<\/h3>\n

            The material of the fan to be used in processes containing hydrochloric acid (HCl), sulfuric acid (H \u2082SO\u2084), nitric acid (HNO\u2083), hydrofluoric acid (HF) and similar corrosive chemicals must be determined according to the chemical properties of the gas to be transported.<\/p>\n

            However, choosing the right fan cannot be done by looking at the chemical resistance table alone. Process parameters such as concentration, temperature, humidity, working pressure, gas phase or liquid droplet content of the gas also directly affect material selection. Different polymer materials may be preferred under different process conditions for the same chemical.<\/p>\n

            Therefore, the fan body, the impeller and all components in contact with the process; Chemical compatibility data and process engineering calculations should be evaluated together and designed.<\/p>\n

            5. Industrial Radial Fan Applications in Fertilizer Production Facilities<\/h2>\n

            Fertilizer production facilities; These are complex industrial processes in which chemical reactions, granulation processes and different raw materials are used in the same production line. Fan systems must therefore be designed to suit not only corrosive gases but also dust load, humidity, temperature and variable process conditions.<\/p>\n

            Fans to be used in production lines containing ammonia (NH\u2083), acid vapors and different chemical components; It must be selected by taking into account the chemical properties of the process gas as well as the particle charge, gas density (specific gravity), temperature and system pressure.<\/p>\n

            Industrial radial fans are mainly used in the following applications in fertilizer production facilities:<\/p>\n

              \n
            • Ammonia (NH\u2083) gas exhaust systems<\/li>\n
            • Acid preparation and storage areas<\/li>\n
            • Granulation and drying units<\/li>\n
            • Dust collection systems<\/li>\n
            • Chemical exhaust lines<\/li>\n
            • Gas flushing (Scrubber) systems<\/li>\n
            • Flue gas purification systems<\/li>\n<\/ul>\n

              Fan Selection for Ammonia (NH\u2083) Gas<\/h3>\n

              In fan design in processes using ammonia, not only the chemical properties of the gas; Process temperature, humidity, particle amount and system operating conditions should also be evaluated.<\/p>\n

              Fine particles carried especially in granulation, drying and product transfer lines; It can have a direct impact on impeller geometry, balance life and maintenance periods. Therefore, the fan type and impeller design should be determined not only according to flow rate and pressure, but also by taking into account the particulate load and process characteristics contained in the transported gas.<\/p>\n

              The fan body and impeller material should be selected according to the chemical structure of the gas to be transported, operating temperature, UV exposure (in open field applications), mechanical strength requirements and process conditions.<\/p>\n

              6. Industrial Radial Fan Selection in Processes Containing Solvents<\/h2>\n

              Solvent-based chemicals are used in many industrial processes such as pharmaceutical production, paints, resins, inks, cosmetics and so on. Solvent vapors formed in these processes are not only in terms of chemical resistance; It requires special engineering in fan design due to its potential to create an explosive atmosphere.<\/p>\n

              When choosing an industrial radial fan, the chemical composition, concentration, temperature, gas density (specific gravity), system pressure and process conditions of the gas to be transported should be evaluated together. Especially in applications where flammable solvents are present, it is not sufficient to select fans based solely on flow rate and pressure.<\/p>\n

              Industrial radial fans are mainly used in solvent-containing processes in the following applications:<\/p>\n

                \n
              • Solvent exhaust systems<\/li>\n
              • Coating and coating lines<\/li>\n
              • Extraction processes<\/li>\n
              • Solvent recovery systems<\/li>\n
              • Mixing and reactor exhausts<\/li>\n
              • Filling and transfer stations<\/li>\n
              • Gas flushing (Scrubber) systems<\/li>\n<\/ul>\n

                ATEX Plastic Fan Selection and Fan Design in Explosive Environments<\/strong><\/h3>\n

                Fan selection in processes where there is a risk of flammable gases, solvent vapors and explosive atmosphere; It should not be done only according to the required flow rate and pressure values. In such applications, process safety, Zone classification, gas group, temperature class and relevant ATEX requirements should be evaluated together.<\/p>\n

                ATEX plastic industrial radial fans; Antistatic engineering polymers (for example, conductive materials such as PP-EL) are preferred for safe operation in processes with explosive environments, with appropriate mechanical design and equipment in accordance with relevant standards. However, appropriate fan selection; It should be determined in line with process conditions and risk analysis.<\/p>\n

                In ATEX applications, the following criteria should be taken into account in fan selection:<\/p>\n
