These screw blowers are available in a new size
The Delta Hybrid series of screw blowers (photo) is now available in sizes D11S and D16S, opening up additional possibilities in the lower-volume flow range. For system manufacturers and operators, this creates more flexibility in the design of smaller-performance ranges. Like the entire series, the new models stand for 100% oil- and PFAS-free process air, high efficiency in the extended turndown of up to 1:5 and energy savings of up to 37% compared to conventional blowers. The D11S has volume flow of 100 to 780 m 3/h, with a turndown ratio of 1:5 and a motor rating of 30 kW. The D16S has a volume flow of 100 to 1,020 m 3/h, with the same turndown ratio and a motor rating of 37 kW. The maximum sound levels are similar, at 69 dB and 70 dB respectively. — Aerzen Maschinenfabrik GmbH, Aerzen, Germany
