Acid Resistant Fan

Fan suitable for oil desulphurization treatment in the industrial process of oil production.
Fluid handling containing sulphuric acid.

V (m³/h) = 100
Pt (Kg/m²) = 550

Low-Medium pressure centrifugal fan.
Forward-curved blades impeller, manufactured in Carbon steel with ebonite lining (ebonited).
Direct drive with standard electric motor.

This model of industrial fan is a derivative from YK 631 R, with case in polypropylene and carbon steel impeller, subjected to an ebonite treatment; it is a process where the impeller has been completely ebonite-coated and then treated in surge tank to vulcanize the landfill. This kind of treatment let the impeller be sulphuric acid-proof.

Vulcanization is an extremely accurate process because, if only a small part of the impeller is not completely clad by the rubber, the whole surface will be attacked by the acid.

Provided options

• Case in Polypropylene
• Ebonized impeller

An Italian company, leader in oil production, requested a special design high pressure fan, strong enough to withstand sulphuric acid attack. Our solution is a polypropylene case and a “carbon steel ebonite-coated” impeller. Carbon steel structure allows good strenght (high rim speed), rubber coating ensures an acid-proof impeller. To reach a state-of-the-art balancing, we repeated this process twice: during the first time, we balanced the impeller before the coating; the second time, we balanced the whole impeller by removing extra weight that we had expected in the construction process.
