Series GDP(A)630
 | Fans GDP series (A) 630 belong to the category of high-pressured and consumption level more than 250000 m3/h and designed to circulate clean as well as dusted air with a temperature up to 200 0C. |
| Parameters >> Acoustic characteristics >> |
Acceptable dust air (gas) should not exceed 2 g / m3 of non abrasive dust. Fans can be used for other operating conditions as well as the temperature conditions and dust level. In such cases the special design is customized by the developer.
The fan impeller has backward curved blades. The design of both straight landing impeller on the motor shaft as well as with the intermediate bearing unit and if necessary with special cooling systems are available. The rotor blades may have a protective coating for fans operating with very dusty air (gases).For fans, conveying very dusty air (gases), the rotor blades may have a protective coating.
A modified execution is available at customer’s request.
Fans GDP(A) 630 type can be used at nuclear power plants for safety classes and 3NO 4NO and I, II, III seismic category. In this case the fans are labled as GDP(A) 630.
