We built this forced-draft, high-pressure blower with a surgeless design on a unitary base for a milling operation processing corn in an ethanol plant. The application called for an inlet elbow, functioning as an inlet box to address the space constraints and minimize the impact on fan performance. To eliminate catch points for material, external welds are continuous and ground smooth.

Industrial dryers are used in a variety of manufacturing processes, and dryers depend on fans to supply and exhaust air to complete the drying processes. The drying systems will not function without fans. We understand that, and so we ensure that our fans are built for maximum reliability and ease of maintenance.
This particular fan was the second of two custom retrofit fans for a pharmaceutical plant. Originally manufactured by a company that is now out of business these fans failed seven years apart. Our application engineers took measurements of the existing fans on-site to design, build, and slip upgraded duplicates into place.
We designed this custom high-pressure stainless steel industrial fan with all the food-grade bells and whistles for a food plant. The design includes 304 stainless steel airstream parts, stainless steel guards, white epoxy on carbon steel parts, Nitrile gaskets, and a Ferrule drain. It’s also designed for fan bearing protection, with bearing RTDs, spring vibration isolators, and a vibration 4-20mA sensor mounted on the fan base.
We provided a backward curved dust collection fan for this food processing plant application. The selected model is among our most efficient, moving medium volumes of air at high static pressures with static efficiencies as high as 80 percent. In this induced draft application, we incorporated an inlet box with expansion joints on the fan inlet and outlet, and spring vibration isolators.
We designed this paddlewheel exhaust fan for a food-grade cyclone application. Basic features included a slip-fit inlet, outlet transition to a round slip fit, spring vibration isolators, and an Arrangement 1 belt drive with a unitary base. Making this fan food-grade required a full complement of custom components, finishes. and materials of construction, including:
We designed an extremely custom high-pressure, high-temperature steam exhaust fan for this emerging green energy technology application. The fan needed to handle very high temperatures up to 1300°F. For that, we used a stainless steel fan casing/housing, a special multi-carbon ring shaft seal, a monobloc bearing assembly with mist oil lubrication, an alloy 625 rotor with a special design for stresses induced by static, dynamic, and thermal loads. We also machined mounting surfaces for the bearing assembly and motor drive.
We delivered a custom high-temperature, high-pressure fan for a heat recovery steam generator (HRSG) application. Designed for temperatures as high as 840°F, the fan has a carbon ring shaft seal, a monobloc fan bearing assembly with oil lubrication, exterior fan insulation, and a raised access door with a flush interior design for the exterior insulation.
In this installation example, we designed and delivered a high-efficiency induced draft fan for a hemp dryer system. The system uses the fan to pull air and particles through, controlling flow using an inlet damper.
We produced this high-temperature burner fan with an efficient backward-curved design and a max temperature of 800°F. The custom design includes thermal insulation for a safe skin temperature and a heavy-duty fan base to prevent vibration.
