Firmac has released the long awaited video of the Pro-Duct Evolution on the Firmac Ltd YouTube Channel. Along with all the other Firmac duct forming machinery videos, this provides an excellent view of the highly technical and innovative machinery being developed by the UK company for the HVAC industry.

Over the past six months there has been a notable increase in demand for Firmac’s Drive Cleat Duct Lines particularly in the Middle East. This semi automated (fully/ modular automated) and versatile machine gives the manufacturer several jointing options to choose from, plain ended ducts to accept a slide on flange, also drive cleat both hit and miss or continuous, both options produce a full box in one pass. Extra notching can be added which will allow the production of ducts with an integral flange of the manufactures choice, (Firmac’s CGF 1 is an example of what can be achieved). Once the sheet has been notched, cut and male and female Pittsburghs formed, it is taken from the line and run through the freestanding rollformer to form the flanges. It is then placed back onto the run out table to be automatically folded into a complete box with seam-closed ready to be transported to site.

Lewis Firth, director, explains, “Expanding ductwork companies that are accustomed to the reliability and consistent high quality output from our entry-level machines such as Mini and ADF lines are now investing in the DCDL. It’s a natural progression for businesses that are looking to increase their level of automation and enjoy the benefits of increased output without the burden of extra labour costs. We are fully aware that all manufactures are not always in a position to invest in fully automated lines, such as the Firmac Pro-Duct CGF 1, but feel that the DCDL offers an excellent semi automatic (fully modular/ automated) alternative.

The drive to automate production processes is linked to the buoyant construction industry.

Sameer Kohli, Firmac’s representative/ agent in UAE and Middle East, attributes the demand for increased automation to regional employers’ reluctance to rely on limited labour resources. “The construction industry is growing but employers are restricted on the numbers of foreign nationals they can employ.  Employers don’t want to depend on a limited labour market and so are looking for increased automation from their machinery. Companies are looking to invest in their futures and the DCDL is helping them do just that whilst meeting current production requirements.”

Watch Omron’s latest video Firmac's partnership with Omron leads to first fully automated duct forming machine and seen how these two forward thinking companies worked together, using the latest technology to produce the industry’s first fully automated duct forming machine.  


Scarborough based duct machinery manufacturer Firmac Ltd. has recently celebrated the completion of their largest project to date. The £1 million plus contract for the fully automated duct forming machine is believed to be the first of its kind in the world.  

The project to design and build a fully automated duct forming machine began in 2012 when Firmac was approached by leading Swiss ductwork manufacturer Dresohn. The challenge was to design and build a fully automated machine which would speed up the duct manufacturing process and increase productivity, reduce operator involvement whilst improving the quality and strength of the ductwork produced.

“The three year project has been a learning curve for all parties involved as we have continually looked to innovate and push the boundaries, introducing new ideas and technology that hadn’t been tried in our industry previously”, explains director Lewis Firth, “We have introduced new robotic technology, more commonly found on the assembly and welding lines in the automotive industry, to speed up the process of duct production and reduce operator input, which also means the process is much more consistent and reliable. Our engineers have included leading edge software which detects faults and relays information immediately to the team in Switzerland and back here at the Scarborough factory. We are extremely proud of the work the whole team has put into the development of this flagship machine and grateful to have such professional suppliers who have worked closely with us throughout the project. The result of three years of hard work is the development of, what we believe, is the most advanced ductwork manufacturing machine in the world”.

Another interesting aspect of the machine is its ability to produce an integral flange as part of the production process.  Lewis explains why the flange is so important to duct manufacturers. “The CGF3 flange has some unique features; there is no stitching or spot welding required and therefore the flange has a clean internal surface which in turn means clean air passes through the duct. It also has air tight properties superior to anything currently available in the market. We believe this flange will be particularly attractive to manufacturers supplying ducting in clean areas, such as the food and pharmaceutical industries”.

To celebrate the completion of the project, the Firth Firmac team along with suppliers and some major European customers were invited to the factory to see and learn more the ground breaking technology. 

Despite its size, approximately 25 metres in length, the modular Pro-Duct DRS CGF3 can be taken apart and reassembled and installed quickly. It will be shipped early December 2014 and should be installed and producing ducts in Switzerland by the end of January 2015.


STR-750 Square to Round Duct Former

The first shipment of STR-750, Square to Round Duct Formers has been sent to Europe, the Middle East and the USA.

STR-750, Square to Round Duct Former

E & S Heating and Ventilation received delivery of their STR-750, Square to Round Duct Former on 13th June. Operating since 1972, E & S provides ductwork contracting services to the heating, ventilating and air conditioning (HVAC) industry and prides itself on being at the forefront of ductwork manufacturing technology and investment. Investing in the STR-750 will enhance production output by forming square to round duct transitions in less than 2 minutes.

Square to Round Ducts in 2 minutes

The STR-750, Square to Round Duct Former from Firmac has revolutionised square to round duct forming. With only one join and no re-shaping required, duct transitions can be produced in less than two minutes.

The duct former is an ideal investment for duct workshops who want to increase output without impacting on floor space as the former can be folded away when not in use.

Roux Young, owner of Venteck Ductwork Ltd., explains how productivity has increased significantly since introducing the STR-750. “Previously we used the folder to produce square to round transitions which was labour intensive and time consuming. The process often distorted the shape of the duct which meant that we had to spend time reshaping each piece to produce an accurate shape.

With the STR-750 we can produce accurate shapes very quickly. We’ve increased daily output from 30 to a massive 200! The machine is easy to use and move around and we’ve found it particularly useful to take on site to make ductwork and insulation cladding".
