Warehouses, livestock farms, poultry farms, commercial/residential complexes. Due to the lack of need for electrical energy, the sanitary facilities etc., air ventilators can be installed on sloping or flat surfaces and create suction while using wind power. Air ventilators are designed and built in such a way that even in If the aerator is fixed, rain water does not enter the channel and the place where it is installed.\r\n## Application of air ventilator\r\n\r\nSuitable for air conditioning of industrial halls, warehouses, livestock farms, poultry farms, commercial complexes, hospitals and residential...\r\nIt is used for different purposes and brings fresh air into the work environment to control humidity and create flow and to remove unpleasant odors and air.\r\nThey say outside, and with the entry of clean air in the environment, it guarantees health and the environment\r\n\r\n\r\nAir ventilator selected by Iranian fans without the need for electrical energy and...\r\n\r\n\r\nSelection of Iranian fans\r\nAir vent sizes\r\nFrom 10 cm to 100 cm according to the request of our respected customers\r\n\r\n### Modern smoke hood (Japanese) selected by Iranian fans \r\nThe modern (Japanese) (Chinese) (cottage) chimney hood is one of the most practical types of fireplace and chimney hoods, which, due to its unique design, receives the special attention of building architects and customers. Due to its structure and design, this cap has a simple installation and is compatible with most environments. In addition, it is a suitable option to get approval from the organization of gas administration and engineering system. Japanese hoods with a special and precise design prevent the return of air into the building and prevent insects and particles from entering the chimney.\r\n\r\n### Damper \r\n Interchannel\r\n Weighted air balance\r\n fireproof \r\nDampers are critical components in air conditioning, heating and cooling systems used to control air flow in ducts and ventilation systems. These devices help improve system efficiency, regulate temperature and humidity, and reduce energy consumption by fine-tuning and controlling air flow. Dampers generally consist of blades or vanes that adjust the amount of air flow by changing their angle.\r\nDampers can be made in different shapes and types, each of which is suitable for specific applications. For example, motorized dampers are used to automatically adjust airflow in complex air conditioning systems, while manual dampers are typically used in simpler systems where frequent adjustments are not required.

Selection of Iranian fans \r\nManufacturer of air dampers in different sizes \r\n\r\n**Definition of air damper (weight)\r\nDamper is a device to control the air in the ventilation system \r\nAnd it has different models such as automatic fire dampers. (electrical or motorized damper) manual damper as well as inter-channel and propeller damper can be selected according to need\r\n** How it works and the use of an air damper (weight)\r\nThe air damper is used to straighten the air flow in such a way that it opens with the air flow from one side of the vanes and when the air flow stops, the vanes are completely closed and prevents the entry of air from the opposite side and the exit of air. Cold or hot in summer and winter, it prevents the energy loss of the environment and prevents the entry of animals and insects when the fan is off. \r\n\r\n**Advantages of using air dampers (weight) \r\nThe air damper moves very smoothly due to its light blades and does not need an external driver or motor.\r\nWith air dampers, the air flows only from one side and prevents air from entering from the opposite direction \r\nAbility to build and install horizontally, vertically and according to customer\'s order \r\n\r\n\r\n**Consumption of air dampers (weight)\r\nFor greenhouses. Livestock farms Poultry farms Industrial sheds. Food and chemical factories. Hospitals. Commercial and residential complexes
