IAP is a complete resource for fans, blowers, and dampers. Craig Equipment supplies, installs and maintains a complete line of industrial and agricultural fans built by IAP.
IAP’s centrifugal fan lineup covers the full spectrum of industrial air movement needs. Backward Inclined and Airfoil fans (Types B and A) deliver high efficiency at low to moderate pressures for clean air and ventilation duty. Backward Curved fans (Type XBC) offer superior static pressure capability for clean industrial process applications. Forward Curved fans (Type F) move large volumes of air at low speeds, making them well suited for ovens, dryers, and furnaces.
For moderate to heavy-duty material handling, IAP’s Industrial Exhauster fans (Types P, ORB, and WT) handle everything from light dust to heavy granules and harsh corrosive airstreams. Radial Tip fans (Type XRT) bridge the gap between backward inclined and exhauster designs, offering higher efficiency with strong particulate and corrosion resistance.
Type HP High Pressure fans handle low to moderate air volumes at high static pressures up to 80 in. wg., suited for fly ash, cement dust, and dry fibrous materials. High Pressure Blowers (Type HPB) provide stable performance from shutoff to wide open volume for combustion air, air knives, moisture blowoff, and fume exhaust applications.
Tubeaxial (TAX) and Vaneaxial (VAX) fans move large volumes of air at low to moderate pressures for continuous duty ventilation, exhaust, and process drying. The VAX adds stationary guide vanes for improved efficiency and higher pressure capability than standard axial designs.
The Inline Centrifugal Airfoil fan (Type ICA) combines the efficiency of a centrifugal airfoil wheel with a compact tubular housing, saving space and reducing horsepower compared to traditional axial inline fans.
Available in four wheel configurations — Backward Inclined (BPG), Forward Curved (FPG), Open Radial Blade (OPG), and Axial Prop (XPG) — IAP Plug Fans are designed for direct installation into system plenums for oven, furnace, kiln, dryer, and air curtain applications, with temperature ratings up to 1,800°F.
The B-Pack is a direct-drive fan purpose-built for top or side mounting on dust collectors, featuring a backward inclined non-overloading wheel, premium efficiency motor, and no belts for virtually maintenance-free operation up to 12,000 ACFM.
IAP fans serve a broad range of ventilation needs including supply and return air, fume exhaust, heat and smoke removal, heating and cooling systems, and make-up air across commercial and industrial facilities.
Process applications span combustion air supply, spray dryers, fluid bed aeration, thermal oxidation, waste-to-energy and incineration, boiler and induced draft service, and kiln exhaust — environments where consistent airflow and pressure performance are critical.
IAP’s exhauster and radial tip fan designs are well matched for dust collection, pneumatic conveying, trim chopping and removal, and air pollution control systems, with wheel options suited for wear liners and heavy particulate loading.
Fan types rated from 250°F to 2,000°F depending on wheel design and alloy construction serve batch ovens, curing furnaces, dryers, glass manufacturing, and other elevated temperature process environments.
Special construction options extend IAP’s capability into demanding environments. Stainless steel construction, chromium carbide liners, spark-resistant builds, and dairy-grade finishes make IAP fans suitable for corrosive, food-grade, and hazardous duty applications where standard construction would not suffice.
