No operator would argue that proper aeration and blower selection are two of the most important considerations at a wastewater plant. In fact, the energy needed for aeration often constitutes a majority of a plant’s electrical usage. The use of an efficient blower can help offset some of those energy requirements. To ensure the most effective results, it’s important to select the proper size, type, and layout of blower equipment. The CycloBlower H.E. 250CDL750 from Gardner Denver delivers best-in-class efficiencies to help reduce total cost of ownership for operators.

Featuring a 3-by-5 helical screw rotor profile, the blower is ideally suited to a wide range of applications, including wastewater treatment, pneumatic conveying, plastic molding and handling, and chemical, industrial, and food processing. It can produce flow ranges up to 6,200 cfm, pressures up to 36 psi, and vacuum up to 22 inches Hg, and it is available with both dual-splash or force-feed lubrication. Force-feed lubrication is required for pressures above 20 psi and vacuum beyond 18 inches Hg. 

The CycloBlower H.E. comes standard as a bottom-discharge configuration with English ANSI flanges and food-grade PTFE-coated rotors. An extensive selection of options includes a top discharge configuration, food-grade PTFE-coated cylinder, RTD ports and metric flanges. 

Meanwhile, the system’s O-ring seals provide durable protection, without the need for gaskets, and helical timing gears are designed to ensure the machine operates smoothly and quietly at all times. It is offered with a ductile iron shaft designed and tested for strength, featuring a high shaft load capacity that is direct and V-belt drive capable. When combined with its durable housing, the package is built for a long life span operating in adverse conditions, helping to improve a facilities operations and maintenance costs even further. The technology can be retrofitted to existing units as well, offering operators the opportunity to upgrade their current blower systems. Its Inpro/Seal premium oil seal offers a contactless dual-ring nonwearing design that extends longevity, reducing maintenance costs while providing protection against leaks.

Other optional extras include graphite air seals for high-pressure applications and a low-, medium-, and high-pressure discharge cylinder. Standard components also include high-quality piston-ring air seals that deliver leak-free operation while providing maximized seal life. 414-212-4700; www.gardnerdenver.com/industrials
