The second of a set of three fans we provided for this copper smelter and fabricator, the furnace fume exhaust fan is the main process fan pulling air through the pollution control oxidizer and exhausting it out of the plant. Learn more about the related oxidizer afterburner combustion fan here.
Backward Curved Fans
The spray dryer supply fan application uses a custom backward-curved fan with epoxy exterior coating, and continuously welded airstream interior parts made of 304 Stainless Steel with SSPC-SP10 bead blast surface preparation. With a split housing, vibration switch, split vibration isolators, pressure tap connections, and an outlet transition to round, this fan is heavy-duty and food-grade.
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.
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.
We designed a high-temperature purge fan for this regenerative thermal oxidizer (RTO) system application. The purge fan blade profile is backward curved to process high airflow at medium pressures. Customized to handle high temperatures, the application called for inlet and outlet expansion joints, and 2” thick insulated housing and inlet box, and an Arrangement 8 direct-coupled drive motor.
For this petrochemical plant application, we custom designed and delivered a backward curved exhaust fan, including a 304 Stainless Steel airstream, 3-inch sound insulation, spring vibration isolators, inlet and outlet flex connectors, and a unitary base.
We recently designed and manufactured a custom induced draft fan for a Regenerative Thermal Oxidizer (RTO) application. The design featured our backward-curved technology with an Arrangement 8 configuration.
For this Regenerative Thermal Oxidizer (RTO) fan application, we custom designed and delivered a high-temperature backward-curved fan with thermal insulation, aluminum cladding, vibration sensors on the bearings, companion flanges, extended lubrication lines, and an inlet box.
This wood product manufacturing application required a belt-driven backward-curved replacement fan matching the dimensions of the existing fan for drop-in-place. The specification called for sandblast preparation with epoxy coating, Teflon coating to give the impeller a non-stick surface, an inlet box, and inlet/outlet expansion joints.
Backward-Curved Fan in Long-Term Storage
We built this fan for our customer’s rotary dryer application. Featuring our rugged backward curved technology with a reinforced housing and base, this fan will operate for decades if properly maintained.
A mere two (2) days after receipt of an emergency rush order, we shipped fan replacement parts including a fan wheel and shaft, bearings, belts, sheaves and bushings, and an inlet cone. This isn’t our average case study, and it was not our average order, but unfortunately, the challenge of fan failure due to poor bearing maintenance is not uncommon.
This straightforward scrap removal application called for a high-efficiency backward curved fan with a premium efficiency motor using an Arrangement 1 V-belt drive and a unitary base.
This spray dryer exhaust fan is the third in a set of three we provided for this dairy operation, along with the spray dryer supply fan and a cooling conveying fan. Dairy operations use multi-stage spray dryers to ensure optimal product quality and drying efficiency. The exhaust fan pulls the air and particulate out of the dryer, with airflow components designed to prevent particles from sticking to the fan.
