Sportect Cabinet

Design and Manufacture of the AirDog SporTect Mobile Deployment Cabinet

McAree Engineering was approached by Dentech with a unique engineering challenge: develop a complete mobile housing solution for the AirDog SporTect air sanitisation system. Unlike many manufacturing projects where a detailed design is supplied by the customer, this project began with a concept and a set of operational requirements. The responsibility for transforming those requirements into a practical, manufacturable and commercially viable product rested entirely with the McAree Engineering team.

The AirDog SporTect system is used in environments where air quality, contamination control and hygiene standards are critical. Applications include pharmaceutical manufacturing, healthcare facilities, laboratories, food production environments, cleanrooms and other regulated industries. The cabinet therefore had to do much more than simply house equipment. It needed to support the deployment of advanced air sanitisation technology while meeting the demanding expectations of customers operating in highly controlled environments.

From the outset, the project required a balance of engineering design, material selection, manufacturing expertise and product development. The customer required a cabinet capable of securely housing two AirDog units while remaining mobile, durable, easy to clean and visually appealing. The finished product would be used in professional environments where appearance and functionality were equally important.

The first stage of the project involved understanding the operational requirements of the system and how the cabinet would be used in practice. Mobility was a key requirement, allowing equipment to be moved between locations as operational demands changed. Hygiene and cleanability were equally important due to the environments in which the system would operate. Durability, ease of maintenance and long service life were also critical factors.

Following concept development and design review, McAree Engineering selected stainless steel as the primary construction material. Stainless steel offered several advantages, including excellent corrosion resistance, durability and suitability for environments where contamination control is essential. The material provides a smooth, non-porous surface that can withstand repeated cleaning and sanitisation without degradation, making it ideally suited to pharmaceutical, healthcare and food-processing applications.

To further enhance the appearance and performance of the cabinet, the completed assembly was powder-coated to provide a durable and attractive finish. The powder-coated surface not only delivers a high-quality cosmetic appearance but also improves cleanability and resistance to wear during daily operation.

The cabinet design incorporated removable access doors, allowing operators to easily access and maintain the air sanitisation units. Anti-static stainless-steel castor wheels were integrated into the design to facilitate movement while meeting the requirements of industries where electrostatic discharge can present operational or safety concerns. These design features ensured the final product was both practical and compliant with the expectations of a diverse customer base.

One of the most significant engineering achievements of the project was the focus on Design for Manufacture principles. During the development process, the engineering team reviewed the proposed assembly methods and identified opportunities to improve both product performance and manufacturing efficiency.

Initial design concepts incorporated pressed PEM inserts to provide threaded fixing points throughout the assembly. However, the team recognised the potential for inserts to loosen or pull out over time, particularly in equipment that may be transported regularly or subjected to frequent maintenance access.

Rather than accepting these limitations, McAree Engineering developed an improved solution. Using advanced sheet-metal forming techniques, punched extrusions were incorporated directly into the components and subsequently tapped to create stronger threaded fixing points. This eliminated the risk of insert failure while simultaneously removing an additional manual manufacturing step. The result was a stronger, more reliable product that could be manufactured more efficiently.

The project also showcased McAree Engineering's investment in advanced manufacturing technology. Components were produced using the company's new Trumpf 5000 punching system, which enabled precise profiling, feature creation, thread preparation and formed extrusions to be completed within a single process. This level of automation improved accuracy, repeatability and production efficiency while reducing overall manufacturing time.

Trutops BOOST software was used during the design stage to check that the parts could be folded without issue and to determine the correct bend radius and k-factor for the parts. It was also used to program the press brakes. This reduced the time taken on the press brakes to fold the parts as it eliminated the need to program at the machine. Using BOOST also meant that the parts would be dimensionally as accurate as possible due to the use to the exact sheet metal parameters calculated by the software.

Following punching operations, components were formed using Trumpf press-brake technology, ensuring high levels of dimensional consistency throughout the assembly. Precision folding enabled complex geometry to be achieved without compromising quality or repeatability.

Perhaps the most innovative aspect of the project was the complete elimination of welding from the design. Traditional cabinet construction often relies heavily on welded assemblies. While effective, welding introduces additional labour, distortion risks, finishing requirements and manufacturing complexity.

McAree Engineering deliberately engineered the cabinet as a fully folded and mechanically assembled structure. Every component was designed to interlock and assemble in a manner that delivered structural rigidity without requiring any welded joints. This approach significantly reduced manufacturing time while improving dimensional consistency and cosmetic appearance. It also simplified future maintenance and improved scalability for production.

The success of the project relied on close collaboration between engineering, manufacturing and finishing teams throughout the business. Design decisions were continually assessed against manufacturing requirements to ensure the product could be produced efficiently while maintaining the highest standards of quality.

The completed cabinet represents far more than a fabricated enclosure. It is a fully engineered product that supports the deployment of advanced air sanitisation technology in some of the most demanding operating environments. The project demonstrates McAree Engineering's ability to transform a customer challenge into a commercially successful product through innovation, engineering expertise and manufacturing excellence.

By combining intelligent design, advanced manufacturing technology, robust material selection and a strong focus on operational efficiency, McAree Engineering delivered a solution that enhances product performance, improves manufacturability and provides long-term value to the customer.
