Today, we spotlight a uniquely engineered swingout BIHS fan, custom-designed by our engineering team for an automotive plant in the Midwest. This fan features a quick-release access door positioned at 9 o’clock on the fan housing, with a flush interior surface that allows easy wheel access. Constructed with stainless steel AMCA C spark-resistant materials free of any silicone, grease-lubricated bearings, and precision laser cutting, it delivers exceptional efficiency and power without sacrificing durability and reliability. We also equipped this fan with a Formsprag backstop clutch to keep the wheel from rotating when not in operation.
Custom
At AirPro, we take pride in designing and manufacturing custom fans tailored to our customers’ specific needs. The fan pictured in the video is still in production: but this gives us an opportunity to highlight some of the specialized features we integrate into our custom fan designs. AirPro designed this particular fan for an API 673 application.
This biomass pyrolysis installation required a fan that can handle abrasive material, gasses, and high-temperatures. We designed a custom radial fan, also known as a paddlewheel fan with an open radial blade design. It featured double-walled housing with thermal insulation and alloy airstream materials to handle high temperatures up to 1500°F. We also built it with a continuously-welded housing interior and a bubble (air-leak) pressure test.
We replaced an industrial exhaust fan originally built by another manufacturer in this brine vapor retrofit installation. The fan is an open radial blade paddlewheel design with a backplate to protect the motor from the material in the air stream. We used AL-6XN® construction material for corrosion resistance and a stuffing box shaft seal to prevent vapor leakage.
We designed this CE-Certified High-Pressure Blower for custom static and thermal loads of operation. Featuring a monobloc bearing design with vibration isolation pads, this custom blower meets European health, safety, and environmental protection standards.
Manufacturing plants often need to retrofit or replace existing fans to keep operations running and increase output. Our team excels at analyzing current fan installations, recommending the best course of action to take, and building the most appropriate fans for the application. That may involve building fans to exactly match existing fan dimensions and performance or modifying fan designs to increase performance.
We custom-designed this high-pressure radial induced draft fan for a scrubber application, with alloy 2205 airstream construction, custom purge air shaft seals, pie-split housing, and an integral inlet box. Configured as a center-hung Arrangement 7 fan, a flexible coupling is used to connect the fan shaft to the motor shaft, and the entire fan assembly is mounted on a unitary base. The application required a severe duty motor rated for use with a Variable Frequency Drive (VFD).
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 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.
We reverse-engineered an existing blower for a drop-in replacement at a pulp and paper mill. Custom-designed entirely with stainless steel, the high-pressure replacement blower includes a flanged and drilled outlet to match the existing connection points and a studded inlet to reuse the customer’s inlet transition. It also has a severe-duty motor.
Custom Fan Colors for Exterior Paint
Custom fan colors allow your centrifugal fan to stand out or blend in with the surrounding industrial application from an external aesthetic perspective.
AirPro recently built two custom blowers for a Fluid Bed Dryer installed at a US thermoplastics / petrochemical production facility. The exhaust blowers were fully customized to match the ordering OEM’s specifications including custom overhung shaft, custom split housing & inbox, and galvanized unitary base.
