(Generic Pics Only) Proline Steel Dampers Proline Steel Structure Dampers use the AUTOCLAD 14 technology and our own engineering experience. We have successfully developed and manufactured an enclosed steel structure elastic damper. The steel structure dampers are remanufactured from 1020 forged steel. The inner and  outer housings feature an elastic rubber inserted in between. The 1015 steel cover plate is welded using modern laser welding techniques for integration of the inner and outer housing to meet SFI specifications and reduce the deterioration of the rubber ring. Proline Steel Dampers Feature: All dampers are tested to 12,500 RPM for explosion proof in compliance with SFI 18.1 Specification All surfaces are anodized for corrosion resistance and appearance.
