Technical characteristics of a standard jet fan
- Motor thermal class: The jet fan motor must have the ability to work at high temperatures (for example, 300 or 400 degrees Celsius) for a certain period of time (usually 2 hours) so that it does not fail during a fire (standard F300 and F400). The higher the thrust, the greater the fan's air movement power.
- Sound Level: Considering that parking lots are closed environments, the fan's noise level should not exceed the permissible limit. It is mandatory to use a silencer (silencer) at the inlet and outlet of the fans.
- Body and blade material: The body should be made of galvanized sheets or corrosion-resistant steel, and the blades are usually made of diecast aluminum alloy to be resistant to mechanical stress.
Nasim Fan Alborz; A pioneer in the production of industrial ventilators in Tehran
- Indigenization of technology: Using the knowledge of domestic engineers, this company has succeeded in producing jet fans that compete with European models in terms of quality, but have a much more reasonable price. Fire resistance and proper performance in critical conditions are the main priority of this collection. Expert consultation and design: Nasim Fan Alborz engineering team is not just a seller; Rather, using fluid simulation software (CFD), it calculates and designs the best layout and the number of fans needed for your project.
- Easy access in Tehran: The location of the factory and head office in Tehran and Alborz minimizes transportation costs for projects in the capital and provides access to warranty and repair services as quickly as possible.
Production steps of high quality industrial jet fan
Production of a jet fan is a complex engineering process. In Nasim Fan Alborz factory, this process includes the following steps:
- Aerodynamic design: The design of the blades and the body is done in such a way that the maximum ventilation efficiency and the least amount of noise are achieved.
- Laser cutting and shaping: Metal sheets are shaped with precise laser cutting and press machines to make a strong and precise body.
- Dynamic balance: One of the most important steps is balancing the fan impeller. If the propeller is not balanced, it will cause severe vibration and reduce the life of the bearings and the engine. In Nasim Fan Alborz, all the propellers are balanced with advanced devices.
- Performance test: Before delivery to the customer, the fans are subjected to strict tests, including high speed test, sound test and air flow test.
Advantages of buying directly from the manufacturer in Tehran
Purchasing an industrial jet fan directly from the factory has many advantages. Intermediaries usually increase the price and may not have accurate technical information. By buying directly from Nasim Fan Alborz, you are in contact with original designers and manufacturers. This allows you to get a customized product that fits the exact needs of your project. Also, in case of any technical problem, the support team of the factory will intervene directly.
Factors affecting the price of industrial jet fan
The price of an industrial jet fan depends on several factors. Knowing these things will help you budget more accurately:
- Motor brand: The use of reliable European electric motors or high-quality domestic and Chinese brands has a great impact on the final price.
- Materials: The thickness of the body sheet, the type of propeller alloy, and the quality of the sound insulation used in the silencers are effective in the price.
- Heat resistance: Fans that have F300 or F400 certification, due to the use of Special insulators and bearings have a higher price than normal models (normal ventilation).
- Accessory equipment: Electrical panel, inverters (VFD) to control engine speed and vibration sensors can add to the final price.
Naseem Fan Alborz company tries to offer a competitive price without sacrificing quality to its customers in Tehran and other cities by optimizing the production line and direct supply of raw materials.
Basic installation and commissioning; Device lifetime guarantee
Buying the best jet fan in the world is also useless without proper installation. Installation of jet fans in tunnels and parking lots requires strict adherence to engineering principles. The installation angle, the distance from the ceiling and walls, and the distance of each fan to the next fan must be executed exactly according to the CFD simulation drawings.
Improper installation can lead to phenomena such as "air flow short circuit", where the air exiting the fan immediately returns to its inlet and practically no ventilation takes place. It is also very important to have strong connections and to use suitable shock absorbers to prevent the transmission of vibrations to the building structure. In addition to selling the product, the technical team of Nasim Fan Alborz provides detailed installation instructions and, upon request, also supervises the installation.
Maintenance and repairs (PM) of jet fans
In order for the ventilation system to always be ready for operation, a preventive maintenance and repair program is necessary. This program includes the following:
- Periodic inspection of the blades: Checking the cleanliness of the blades and the absence of cracks or deformation.
- Lubrication of the bearings: Regular greasing of the motor bearings according to the manufacturer's instructions.
- Checking the electrical connections: Unscrewing the terminals and checking the cables to prevent overheating and connection.
- Vibration test: Measuring the amount of vibration of the device for early diagnosis of bearing failure or imbalance.
The role of jet fans in receiving fire department approval
In Tehran, receiving the completion of work on large buildings and the license to operate tunnels is subject to the approval of the fire department. The ventilation and smoke control system is one of the most important parts of this approval. The use of standard jet fans and the correct implementation of the smoke ventilation system is a necessary condition to pass this legal stage. With full knowledge of the rules and regulations of the Tehran Fire Department, Nasim Fan Alborz produces products that meet all the requirements of this organization and paves the way for manufacturers to receive approval.
The future of ventilation industry in Iran
According to the ever-increasing population growth and the need for more underground spaces such as subways and urban tunnels, the jet fan production industry in Iran has a bright future. Companies like Nasim Fan Alborz, by investing in research and development (R&D), are looking to produce smarter, more energy-efficient and quieter fans. The use of high efficiency engines (IE3 and IE4) and the design of bionic blades (inspired by nature) are among the future goals of this industry in the country.
Summary and conclusion
Production and sale of industrial jet fans in tunnels and large parking lots in Tehran is a vital link in the chain of safety and welfare of citizens. Choosing an efficient ventilation system not only provides healthy air for breathing, but also saves lives in critical situations. Eliminating traditional ducting, reducing energy costs, and making ventilation smarter are undeniable advantages of using jet fans.
If you are a manufacturer, contractor or installation consultant in Tehran and you are looking to buy a high quality industrial jet fan with a reasonable price and a valid warranty, the Nasim Fan Alborz industrial ventilator production series in Tehran is the best option for you.
