Fan Types and Configurations
Alloy Engineering designs and manufactures high-temperature fans and blowers in a range of configurations to meet the demands of industrial furnace and process environments:
| Fan Type | Description & Typical Applications |
|---|---|
| Centrifugal Fans | Most common for high-temperature recirculation in belt furnaces, box furnaces, and kilns. Available in radial, backward-curved, and forward-curved blade designs depending on pressure and volume requirements. |
| Axial Fans | Used for high-volume, lower-pressure airflow in heat treating and atmosphere-controlled furnace applications. Suitable for continuous service at elevated temperatures. |
| High-Temperature Blowers | Designed for forced-air applications in process environments where operating temperatures exceed 1000°F. Alloy construction required to prevent warping, oxidation, and blade erosion at extreme heat. |
| Induced Draft Fans | Used to pull exhaust gases through furnace systems. Critical in combustion environments where standard steel construction would fail prematurely. |
Materials and Construction
Standard carbon steel and stainless steel fans fail quickly in high-temperature furnace environments due to oxidation, creep, and thermal fatigue. Alloy Engineering fabricates fan wheels, housings, and shafts from high-nickel alloys rated for continuous service at temperatures that standard fans cannot withstand.
| Alloy Grade | Max Temp | Best For |
|---|---|---|
| 309 / 310 Stainless | ~1900°F | General heat treating and annealing furnaces; cost-effective entry point for high-temp fan applications |
| 330 (RA330) | ~2100°F | Atmosphere furnaces and carburizing environments; excellent oxidation and thermal shock resistance |
| Alloy 600 / 601 | ~2100–2200°F | Hydrogen atmosphere and high-pressure furnace environments; superior oxidation resistance |
| Cast Heat-Resistant Alloys | ~2200°F+ | Extreme-duty applications; cast alloy fan wheels resist creep at sustained high temperatures where wrought alloys deform |
Alloy Engineering also provides industrial fan repair services for existing fans that have warped, cracked, or lost balance — often a faster and more cost-effective option than full replacement.
