For this industrial oven exhaust application, we custom designed a high-temperature plug fan. The design incorporated forward-curved blades, housing, a 12 inch insulated plug, belt drive, and a unitary base, with a heat slinger on the shaft to help dissipate heat from the oven.
Case Studies
In this Kaolin Mining installation, we provided an induced draft fan for dust collection. Kaolin (hydrated aluminum silicate) is a high-value, high-volume industrial clay used largely in the production of paper, as well as ceramics, cement, fiberglass, and many other industrial production processes. Its naturally fine particles mean dust collection is critical in the mining process for air quality improvement and safety.
We designed this material handling fan to replace a competitor fan wheel, which had been failing every week. It’s used for moving a mixture of copper and aluminum shavings in this industrial metal-making application. After months of operation, our replacement is in good working condition.
We provided a set of three fans for this thermal oxidizer application designed for pollution control at a copper purification, treatment, and manufacturing plant.
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 designed this heavy-duty pollution exhaust fan complete with OSHA (Occupational Safety & Health Administration) guards to provide the required level of safety and protect workers from accidental contact with the fan blades. The custom design uses a 20HP motor with a V-belt drive. A ceramic felt shaft seal and flanged inlet and outlet prevent gas leaks in the system. A bolted access door allows for easier maintenance.
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.
This installation is an example of a purge air system utilizing an AMCA Type “A” Spark Resistant Exhaust Blower. Designed for the OEM as part of the larger purge system to help prevent contamination of electrical surfaces from overheating, corrosive gasses, and dirt by moving clean air through the system. This high-pressure arrangement-1 blower features an aluminum fan wheel and housing for spark resistance.
The quick-ship combustion blower for this burner application comes from our Backward-Inclined Quick Ship (BIQS) line of highly-efficient off-the-shelf fans with pre-set performance ranges specifically designed to meet the time-constrained demands of Original Equipment Manufacturers (OEMs).
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.
