Model FA-W

In these systems, the connection of the impeller to the electric motor is indirect and coupling-based.
The design of these types of fans is based on the impeller method between two bearings (Impeller Between Bearing) according to the AMCA standard.
The airflow capacity is up to approximately 1,000,000 cubic meters per hour.
The static pressure can reach up to about 15,000 pascals.
The diameter of the fan impeller can reach up to 3250 millimeters.
The inlet air volume can be adjusted using a damper or by changing the speed frequency.
These series of fans can operate effectively in temperatures ranging from -40 to 500 degrees Celsius.
The position of the outlet mouth relative to the inlet and its angle relative to the horizon can be selected according to the AMCA standard.
The ability to install any accessories such as dampers, silencers, bird screens, chassis, etc., is available on these air handlers.
Most of these fans are used in systems for collecting and transferring gases, materials, and polluted air.
Based on the capacity and performance efficiency of the fan, the impeller blades can be designed as either backward curved or backward inclined.
The vibration balance of these fans is according to the ISO standard DIN ISO 1940-1 grade G 6.3 <4 mm/s.

In environments with high corrosion and acidity, stainless-steel 304 or stainless-steel 316 materials are used for the body and impeller of the fans (stainless-steel Fans).
In the presence of flammable gases and dust in the fan environment, to prevent sparks and explosions, the fan is completely isolated from the surrounding environment, and also, a layer of copper or composite insulation is used on the potential collision area between the two-metal impeller and fan body (Explosion & Spark proof Fans).
In the oil, gas, and petrochemical industries, centrifugal fans are designed and manufactured according to the international standards API 560 & API 673.
