Technical Specifications of DamaTajhiz 40000 CFM Air Washer Model DTA-40

1. Chassis:
   
   • The main chassis of the DamaTajhiz 40000 CFM Air Washer Model DTA-40 is designed and manufactured using original steel channels. After completing welding and finishing operations, the chassis is fully coated with multiple layers of electrostatic powder paint. In addition, to ensure vibration-free operation, all DamaTajhiz air washers are equipped with high-quality rubber vibration isolators with long service life.
2. Structural Frame:
   
   • The structural frame of the DamaTajhiz 40000 CFM Air Washer Model DTA-40 is made of robust aluminum profiles (corrosion- and rust-resistant) in two types: five-bend and seven-bend designs. The entire length of the profiles is fully insulated and sealed to prevent thermal and cooling losses.
   • It should be noted that high-quality fiber-reinforced polyamide corner joints, resistant to heat and weather conditions, are used in the construction of DamaTajhiz air washer structures.
3. Fan:
   
   • The fan is one of the main components of the air washer unit, responsible for drawing air into the system, passing it through the main chamber for cooling, and finally distributing the conditioned air to the desired space through air distribution ducts.
   • The fans used in DamaTajhiz air washers across all capacities include centrifugal, forward-curved, and backward-curved types, manufactured with the highest quality standards, primarily from the Italian brand Nicotra or equivalent brands. These fans offer long service life, extremely low noise levels, maximum static and dynamic balancing, and replacement warranty conditions.
4. Electric Motor:
   
   • The electric motors used in DamaTajhiz horizontal air washer units are selected from the highest-quality and most reputable brands available in the market, such as Siemens or equivalent European brands, featuring IP55 protection class and Class F thermal insulation, with long service life and replacement warranty options.
   • Depending on the airflow capacity, air volume, and pressure drop of the air washer unit, the required motor power varies. As the airflow capacity increases, a higher motor power is utilized.
5. Filter:
   
   • Due to the importance of breathing clean air free from dust and airborne particles, the air filtration system in air washers plays a crucial role.
   • DamaTajhiz air washers in all capacities are equipped with multi-layer aluminum filters. These filters consist of aluminum mesh arranged in a honeycomb structure with seven overlapping layers. As air passes through the filter, dust and airborne particles are removed, delivering clean and comfortable air to the intended space.
   • Key features of these filters include high dust absorption efficiency, washability, and easy installation and replacement.
6. Dampers:
   
   • The air dampers used in DamaTajhiz air washers feature airfoil-shaped aluminum blades arranged in opposite directions. Damper movement is facilitated by durable plastic gears made of polypropylene, and the damper edges are sealed with plastic gaskets. Installation of damper motors on the air washer dampers is also possible.
7. Inspection Door:
   
   • To ensure safe and convenient access to the internal components of the air washer for periodic inspections, servicing, potential repairs, and internal part replacement, all DamaTajhiz air washers are equipped with a hinged inspection door with polypropylene hinges and handle, ensuring complete air-tight sealing.
8. Insulation:
   
   • To reduce noise and ensure quiet operation of the DamaTajhiz 40000 CFM Air Washer Model DTA-40, as well as to prevent thermal and cooling losses, all internal surfaces and the unit body are fully insulated using 20 mm thick polypropylene material.
9. Shaft and Bearings:
   
   • The shafts and bearings used in DamaTajhiz air washers across all capacities are sourced from the Japanese brand FYH or equivalent models, offering excellent quality, long service life, and high resistance to moisture and corrosion.
10. Coil:
    
    • All coils across various capacities are designed and manufactured by DamaTajhiz with high quality standards, considering engineering parameters such as coil heating capacity, altitude above sea level, number of coil rows, copper tube thickness, type of fins used, fins per inch (FPI), airflow volume in contact with the coil surface, and air velocity.
    • The primary surface of the coils consists of seamless copper tubes with high thickness, while the secondary surface is made of a large number of high-quality aluminum or copper fins, based on customer requirements. Coils can be manufactured with FPI values ranging from 8 to 14 and are available in three types: hot water coil, electric coil, and steam coil.

Installation Considerations for DamaTajhiz Air Washer Model DTA

• Provision of a floor drain in the air washer room is mandatory to facilitate cleaning and periodic maintenance services.
• After installing DamaTajhiz air washer units, in order to prevent vibration transmission from the equipment to the surrounding foundation area, the installation of rubber vibration isolators or plastofoam around the foundation is essential.
• To allow for potential coil replacement during the long operational life of the air washer, and in accordance with engineering standards, a clear space equivalent to 1.5 times the unit width must be provided on one side of the installation area.
