Original oil and gas trade magazine vintage ad for DOLLINGER CORPORATION. Main office and factory was located at 5 Centre Pk, Rochester, NY. It Filters, and Silences! The Staynew model DS intake filter does both, in a single compact unit. Save on wear of compressor and internal combustion engines, reduce intake clamor. This unique 1950 old industrial engine equipment magazine advertisement would display beautifully matted and framed.
