Eurus Blower, a wholly owned subsidiary of Shandong Zhangqiu Blower Co. (SZB), one of the world’s largest, most modern suppliers of rotary lobe blowers, announced the introduction of the ZAS20 blower series blower to the North American market. These blowers are used in a wide range of applications.
Eurus ZAS20 series rotary blower
The Eurus ZAS20 series is a modern, heavy-duty blower. Its impellers are made with ductile iron (60,000 psi tensile strength) and statically/dynamically balanced to industry standards for long-term durability. The shafts have alloy steel forgings and are flange-mounted with high-tensile cap screws. The blower’s double-row spherical roller bearings support the shaft assemblies and control impeller axial position. The cylinder and headplates feature precision-machined grey iron with cast ribs for strength and heat dissipation and support horizontal or vertical flow. Leak-tested to 1.25 × casing pressure; optional hydrostatic test to 1.5 × casing pressure. The timing gears are made of forged steel, are AGMA-standard, carburized and ground (58–60 Rc hardness), while the spur design avoids axial loads.
This series uses a standard energy-saving splash lubrication system or an optional positive pressure lubrication system. It includes a gearbox oil sump, oil filter and cooler, pressure gauge, relief valve and low oil pressure safety switch. It has optional special materials such as the 304/316 stainless steel or ductile alloys for enhanced corrosion resistance.
The Eurus ZAS20 series flow range is up to 42,276 cfm, max Δ pressure is 15 psi, max Δ vacuum is 15″ Hg, max RPM is 980 and min RPM is 730.
“This exciting ZAS20 Series blower offers our customers a greater selection of high-quality blowers. The ZAS product introduction complements recent ZCS824 Vacuum Truck Blower, ZDL Bulk Truck Blower, EBox Factory Standard Packages, ISB Series Screw Blower, VR Series (steam blower) product introductions and growing success with our multistage centrifugal product. Eurus Blower’s customer service focus is unmatched in the North American market as we continue meeting customer needs,” Roger Blanton, General Manager, Eurus Blower.
