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 dust collector application called for a highly-customized high-pressure blower. The specification included a custom housing and an impeller design for a range of static, dynamic, and thermal loads of operation.

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.

For this protein rendering installation, we provided a high-volume single-width backward inclined industrial fan with 304 stainless steel airstream parts, an Arrangement 9 belt drive, and Occupational Safety and Health Administration (OSHA) safety guards. This backward inclined fan moves high volumes of air and includes a non-overloading horsepower design for low-pressure applications like this one.

We designed this custom backward-curved tempering air blower on a skid with a 75 HP IEEE 841 (Institute of Electrical and Electronics Engineers) severe duty motor.

The custom, induced draft fan we designed for a wood industry dust collector application uses a radial tipped blade profile with a custom base design. It includes an outlet damper for flow control, pie-split housing for easier maintenance access, and a 100HP V-drive motor. The heavy-duty fan resists particle build-up and delivers high efficiency in this high-volume application.
