Durable Finishing for Fan and Blower Housings and Components

Fan and blower manufacturers need a finishing partner that can handle both small-batch and high-volume production. Winona is that partner, backed by the quality certifications to deliver and two northern Indiana plants with two powder coating lines each. We are also one of the few finishers to offer both E-coat and powder coating services.

Built for Fan and Blower Manufacturing

Industrial fans and blowers operate in environments that can be hard on metal. Housings and components may be exposed to moisture, dust, chemicals, heat, vibration, washdown, UV, outdoor weather, and constant handling during installation and maintenance.

Durable corrosion protection for indoor, outdoor, and industrial environments
Consistent coverage on housings, scrolls, panels, frames, and guards
Wide color and finish selection for branded or visible equipment
Specialty powders, including high-temperature, metallic, and AAMA architectural options
Small-batch flexibility and high-volume production capacity
Consistent quality across recurring product lines
Quick turnaround to support assembly and shipping schedules
Packaging and delivery support for finished components

A quality finish protects the metal, supports a professional appearance, and helps your products stand up to years of service. Winona works with manufacturers to review part material, size, geometry, operating environment, appearance requirements, coating specification, and production volume before recommending a process.

Powder Coating for Housings and Components

Powder coating gives fan and blower housings a tough, attractive finish that resists chipping, scratching, abrasion, moisture, and chemical exposure. It also provides a smooth, uniform appearance that reflects the quality of your equipment.

Durable, corrosion- and UV-resistant finishes
Consistent color and gloss across production runs
Protection during shipping, installation, and service
High-temperature powder options where applicable
Metallic or decorative finishes
Strong edge and surface coverage
A low-VOC alternative to conventional liquid paint

Winona offers a huge range of colors and finishes, so manufacturers can match brand standards, customer requirements, or application needs. Specialty powders are also available for applications that call for added performance or a distinct look.

Specialty Powder Options

Not every fan or blower application has the same finishing requirements. Winona offers specialty powders to help manufacturers match the coating to the job.

High-temperature powders for components exposed to elevated heat
Metallic powders for premium or distinctive appearances
AAMA architectural powders for applications that require superior exterior weathering and color retention

Our team can help you evaluate which option fits your operating environment, performance requirements, and appearance goals.

E-Coat for Complete Corrosion Protection

E-coating deposits a uniform epoxy coating across conductive metal parts, making it particularly useful for fan and blower components with complex shapes, recessed areas, tight corners, and other features that are difficult to cover with spray application.

Uniform coverage with controlled film thickness
Corrosion resistance on complex assemblies and internal surfaces
Efficient processing for higher-volume programs
A standalone functional finish
A corrosion-resistant primer beneath powder coating

Winona's E-coat line includes a 13-stage pretreatment process with laser scale removal, zinc phosphate, and RO water. Automated indexing helps minimize air-pocket effects as parts enter the tank, supporting consistent coverage across intricate geometry.

E-Coat Primer + Powder-Coated Topcoat

For fans and blowers used in harsh, humid, corrosive, or outdoor environments, Winona can combine an E-coat primer with a powder-coated topcoat. The E-coat provides uniform corrosion protection across the entire part, including hard-to-reach areas. The powder topcoat adds a durable exterior finish with color and abrasion resistance.

If the powder coating is chipped or scratched, the E-coat beneath it continues to protect the metal from rust and chemical corrosion. This layered approach can extend the service life of housings and components exposed to demanding conditions.

Experienced Coating for Industrial Fan and Blower Applications

Winona finishes housings and related components for manufacturers serving a broad range of industrial and commercial markets:

Industrial fan and blower housings
Centrifugal and axial fan components
Blower scrolls, inlets, and outlet assemblies
Fan frames, guards, and support structures
Ventilation and air-handling equipment housings
Dust collection and industrial air-movement components
Agricultural and livestock ventilation equipment
HVAC and mechanical equipment components
Motor mounts, brackets, and access panels
Equipment enclosures and fabricated assemblies

The right finishing process depends on the substrate, part geometry, operating environment, temperature exposure, appearance requirements, and production volume.

The Winona Advantage for Industrial Equipment:

Small-Batch to High-Volume Capability

Winona supports everything from smaller production runs to high-volume programs, giving fan and blower manufacturers a single finishing partner as their needs change.

Quality Certifications

We have the quality certifications to deliver for demanding customers. Winona is ISO 9001:2015 certified, supporting consistent, documented finishing processes.

Two Plants, Four Powder Lines

With two northern Indiana plants and two powder lines at each, Winona has the capacity and flexibility to keep production moving.

Powder Coating and E-Coating Under One Roof

Winona is one of the few finishers to offer both E-coat and powder coat services, allowing manufacturers to choose the right solution or combine both for maximum corrosion protection.

Colors, Finishes, and Specialty Powders

From standard colors to high-temperature, metallic, and AAMA architectural powders, Winona can help you find a finish that fits your product and your customers.

Quick Turnaround and Industry Recognition

Winona offers quick turnaround and has been a Products Finishing magazine Top Shop award winner four years running, in 2020, 2021, 2022, and 2023.
