Case Study

Our dampers in the Montreal public transport.

High-Pressure industrial dampers.

Montreal’s Transit History

The collective transport has been around in the city of Montreal for over 150 years. As a matter of facts, on November 27th, 1861, the first tramway, pulled by horses, made its appearance. Throughout the years, and multiple changes, such as going public in 1951, the Société des Transports de Montréal – STM, has always fulfilled its mission; provide Montrealers with an efficient, reliable, and affordable collective transport service.

The trams circulated in the city between 1861 and 1959, in 1919 buses were introduced to the offered services. The subway was introduced in 1966 and adapted transport made its appearance in 1980.

The project of building a subway system was taken in 1960 by, then mayor, Jean Drapeau with a budget of 132 million. With the addition of an extra line, that amount rose to 213 million the second year of construction.

In 2020, most of these constructions were over 50 years old and need maintenance, repairs or simply replacement. Some of the dampers present in the Montreal metro were outdated and did not meet the requirements in place. They were noisy, unsafe, hard to maintain, and some of the parts were just not available anymore. It was the case for the dampers in multiple stations, they had no other choice but to replace what had been installed many years ago.

The STM and AQC

This is why we worked in collaboration with the STM to install our High-Pressure Stainless-Steel Industrial Dampers. Aireau Quality Control offered dampers that met the high requirements specified by the STM for the replacement of the old equipment. Our dampers can be disassembled for repairs and the seal created by our airfoil blades when the damper is closed is exceptional, the performance of this damper is outstanding.  We also incorporated some of our impressive features such as our double sealed gasket design and our single piece transmission axel with D shaped ends.

Our Advantages

Dampers have evolved over the last 50 years and our high-pressure stainless-steel damper is cutting edge technology. To assure the highest quality and results of our products, we sent our dampers at AMCA facilities in Chicago to put them to the test. Without surprise, our dampers came back having passed AMCA’S highest tests with flying colors. Our dampers are certified 400-D-18 for air volume control and can withstand temperatures of over 752oF (400oC).

We are now in over 12 subway stations on the Island of Montreal, in various tunnels, and are working on many more projects. Our dampers have surpassed all expectations and are in demand.
