Our mission since we began in 1954To forge a trusted relationship built on the best solutions to fit your individual air movement needs.

60 years and counting.

We started in 1954 as a small sheet metal shop. Back then, we mainly serviced the giants of the furniture and wood manufacturing industries. Jump ahead 60 years and those seemingly invincible customers are all but gone. And, yet, we remain.

Built to last.

Like our products, our business is built for the long term. We have grown into a major supplier of the design, fabrication, installation and service of industrial dust collection systems throughout North America. The key has been
a reputation for unrivaled expertise, workmanship, products, customized solutions and, most importantly, service.

Continued Growth.

While dust collection and control is an integral part of our business, it’s not the only part. If your industry produces dust and waste materials from your manufacturing processes, we have a system application to help. The Koger Air brand of systems can be classified as pneumatic and material conveying systems and includes dust collection and control, industrial ventilation, air filtration, fume exhaust, process materials management, and piping systems for biomass, bioenergy, thermal and catalytic oxidation applications.

Standards of Customization.

As the industry has grown and evolved, so have we. In addition to our standard products, we also offer you a custom metal fabrication division to create industry-specific products for specialized manufacturing processes. In fact,
companies in our own field often outsource their heavy-duty industrial and stainless steel fabrication products to us.

Value-Added Services.

To complement our contract system business, we also offer value-added products and services, including the Koger line of standard and custom industrial sheet metal components, fans, airlocks and cyclones, as well as the fabrication of customized industrial products.

Service above all.

We are committed to offering the best solutions available. Above all, we are about meeting both standard and special fabricated product requirements, and each customer can count on getting orders on or before scheduled delivery dates. Standard components are stocked and ready to ship, and custom products are assembled and shipped to exceed or meet deadlines. All you have to do is let us know what we can build for you.

Here’s to 60 more.

It’s been our honor to service our customers, new and old, and we look forward to the challenges and opportunities the next 60 years will bring.


Convenient Solutions.

Koger Air Corporation offers 100,000 square feet of manufacturing and warehousing space in Martinsville, Virginia and is centrally located between Roanoke, Virginia and Greensboro, North Carolina to serve you and customers nationwide.

Koger Custom

Koger Custom is a part of the Koger brand that captures all our Metal Forming and Fabrication Capabilities. We have the right people and the right equipment to create industry-specific products for specialized manufacturing processes. We are often outsourced by customers and competitors alike to fabricate their heavy-duty industrial and stainless steel projects.

Getting it Right.

We believe that the right people are the ones who have the right training and skills to understand which equipment and materials are right for the job. We feel that’s the right way to give our customers exactly what they need.

The Right Team of Experts.

We continually program, form and fabricate customized shapes for industrial applications. Our teams are made up of Project Managers, Computer Programmers and Shop Fabricators. The project managers are equipped with the latest CAD capabilities and our internal computer programmers develop the software that drives our plasma arc cutting systems. They both work with our shop fabricators, averaging 17 years of service, who are highly specialized in forming and fabricating industrial-strength assemblies and welcome new opportunities and challenges.

What We’re Capable Of.

Metal Shearing Services
Koger Air offers a range of metal shearing services to customers requiring these services. Metal shearing is a process for cutting sheet metal to size out of a larger stock such as roll stock. Shears are used as the preliminary step in preparing stock for stamping processes, or smaller blanks for CNC presses. We operate two metal shears with a maximum capacity to shear 10' of 1/4' thick mild steel plate to assist customers to produce custom fabricated metal parts.

Plasma Metal Cutting Services
Koger Air offers two CNC plasma metal cutting machines with 10' x 16' cutting surfaces that have a maximum capacity to burn up to 2' mild steel plate.

Sheet Metal Braking Services
At Koger Air we offer sheet metal braking services to our customers since 1954. During our sheet metal braking process we use an open-frame single action press to bend, blank, corrugate, curl, notch, perforate, pierce, or punch sheet metal or plate. We operate three CNC press brakes with a maximum capacity of 320 tons able to break 14' of 3/8' mild steel plate.

Sheet Metal Blanking, Drawing and Stamping Services
At Koger Air we offer sheet metal blanking and sheet metal stamping services to our customers. Sheet metal blanking is cutting up a large sheet of stock into smaller pieces suitable for the next operation in stamping, such as drawing and forming. The blanking process is often combined with a piercing operation.

We operate a 500 ton CNC hydraulic state-of-the-art punch press with 48' x 48' bed, 24' open height and 6' shut height to create blanks in the custom fabricated metal parts.

Sheet Metal Punching Services
Punching is the process of forming metal components using a punch. The punch is usually the upper member of the complete die assembly and is mounted on the slide or in a die set for alignment (except in the inverted die).

We operate two Iron Workers with a maximum capacity of 300 tons cutting and punching capabilities. Our steel metal punching service is very competitive, we use some of the most advanced and efficient punches available.

Steel Rolling, Steel Angle Bending Services
Koger Air Corporation provides specialized metal rolling and steel angle bending services. Steel rolling and steel angle bending is a continuous bending operation in the metal forming process during which either metal sheet or strip metal is plastically deformed along a linear axis by being passed through a series of roller dies that progressively shape and contour the metal.
Rolling (Flat Metal)
We operate four sheet steel rolling machines with a maximum capacity to roll 10' of 3/8' mild steel or 1/4' plate of abrasion resistant steel.
Rolling (Angle and Flat-Bar)
We offer five angle and flat-bar rolling machines capable of rolling angle iron 3' x 3' x 3/8' leg-out, 2' x 2' x 1/4' leg-in, and 3' x 3/8' flat-bar.

Welding Services
At Koger Air our welding staff provides ARC welding, MIG welding and TIG welding to our customers. During the welding process two or more metal parts are permanently joined together by melting both materials. The molten materials quickly cool, and the two metals are permanently bonded.

Over the years, we’ve mastered the proper pneumatic material handling and ventilation of industrial manufacturing processes throughout North America.

The types of systems we handle include dust collection and control, industrial ventilation, air filtration, fume exhaust, process materials management, pneumatic trailer loading, and product metering.  We also design, fabricate and install piping systems for biomass, bioenergy, thermal and catalytic oxidation applications.

Projects Managed.

Each project is handled by a dedicated hands-on project manager. They work with you to identify your specific needs, create a tailored, custom solution and oversee your project from its start to its completion. We provide everything you need: from on-site inspections, project evaluations and research to proposed resolutions and CAD drawings.

Customized Solutions.

Every environment is different. The key to a clean inside and outside environment is the quick and efficient capture of dust. Each Koger Air system is custom-designed to handle your specific airflow and product collection needs, including transfer methods for waste collection, material separation or recycling.


Our teams are fully equipped and staffed for all phases of transporting, erecting, storing and on-site assembling of parts, equipment and systems.  Installations are performed by experienced field mechanics who work to meet your specifications and time schedules with minimal or no interruption to your manufacturing processes.  We also offer dismantling and relocation services for your existing systems.
