Custom Blowers & Gas Boosters


Spencer solves air and gas handling challenges that are so difficult, sometimes the only alternative to our involvement is to change the process. When you don’t have that option, Spencer capabilities and ourEngineering Edge are your best resources. High-performance blowers and gas boosters can be built to handle corrosive and toxic sulfides, halogens, acids, flue and stack gases, cyanides and ammonia. Maximum parameters include temperatures to 1100°F, housing design pressures to 1000 PSIG, operating pressures to 300 PSIG.

We create cost-effective designs that meet your performance needs without overkill. For example, if you have a process involving corrosive gases or fumes that attack carbon steel or cast iron, we have several ways to protect blower components in the gas stream. We might recommend a special coating for those components, substitution of a special material such as 316L stainless steel, or use of an extra-thick standard metal with a designed-in corrosion allowance.

Nuclear industry experience

Besides making the first hermetically sealed multistage gas boosters and UL Listed gas boosters, Spencer also made the first gas boosters approved for use in nuclear breeder reactors. Our special high-pressure gas boosters with welded seams and internal electric motor are virtually leak-free; shaft seals are not required. We have lengthy experience with nuclear power plant blowers and gas boosters for component cooling, process ventilating, off-gas systems and LOCA (Loss of Coolant Accident) systems.

Even if you’re not involved in the nuclear power industry, it’s reassuring to know that Spencer is a trusted vendor for the most critical air and gas handling applications in the world.


Hermetic & Custom Designs

For zero leakage of process gases, Spencer can provide hermetic gas boosters with the motor totally enclosed in the blower housing. To withstand housing design pressures up to 1000 PSIG, centrifugal Spencer blowers of any style can be built with pressure vessels using ASME Code guidelines. For temperatures up to 1100°F, Spencer can equip its blowers with water-cooled bearings, special seals and centerline mounted housings.
