Buffalo "B" volume blowers and exhausters: standard type "B" volume blower, catalog 178, section L
A 1910 catalogue section from the Buffalo Forge Company of Buffalo, New York, presenting its standard type B volume blowers and exhausters for ventilation and industrial air handling engineers. The pictures are sober photographic-style engravings of cast-iron fan housings with flanged round discharge outlets, bolted pedestal bases, and direct-drive motor or shaft assemblies. A designer could draw on their dense mechanical forms, tonal shading on dark metal, and the stark product-shot framing against plain grey paper.
