When constructing a ship lots of welding activities take place. These fumes need to be captured in order to protect your personnel.

From leisure activities to carrying the vast majority of all traded goods worldwide, ships have always played a significant role in our day-to-day lives. When shipbuilding technologies were introduced to new developments in the 19th century, welding replaced riveting, providing shipbuilders with major benefits including higher efficiency, smoother surfaces and lighter structures. Consequently, welding is now considered to be one of the most popular hot-work processes in the shipbuilding industry. 

However, while welding has given the shipbuilding business important opportunities, welding fumes expose your workers to serious health risks if you do not take the appropriate action. As stated by the International Agency of Research on Cancer (IARC), long-term exposure to welding fumes can lead to multiple types of cancer. Taking the necessary precautions on your shipyard is therefore of the essence. 

At Plymovent, we provide our clients with high-quality extraction and effective filtration systems that are designed to protect you and your workers from the start of construction until the day the ship is ready to begin its journey on the water. 


Our products 

Being part of the shipbuilding industry means working in tiny, confined places but also incredibly big ones. No matter where you work, Plymovent can provide you with the proper solution.


Multiple arm systems and downdraft and backdraft workbench

Plymovent offers a wide range of extraction arms for at-source capture of welding fumes and grinding dust. Besides offering our clients a variety of single-arm systems, we also offer the ultimate multiple arm systems. Depending on your specific application, you can choose different arm lengths and diameters. The filter in this system also ranges from small-single filters to big modular self-cleaning filters and can be adjusted over time. This automatic system will also guarantee a lower use of electricity and energy consumption, helping you shorten your return on investment (ROI). 

Another at-source extraction method is our downdraft and backdraft workbench. The DraftMax extracts the fumes and dust before reaching the breathing zone through the working surface and optional backdraft panel. The DraftMax comes in two forms: the DraftMax Eco or the DraftMax. We can help you find the best workbench for your specific application. 

At source-capturing is not or hardly possible when you are working on something in a very big place or when you are several feet up in the air. Thus, when at-source capturing or extraction hoods are not feasible, general air cleaning and ventilation is the preferred approach. These systems enable you to stay below the limit values to keep you and your workers safe.


Diluters and the Push-Pull system

We offer you and your workers two types of diluters including the SCS-Diluter and the MDB-Diluter that are designed to control the concentration of welding fumes at your workplace. Whereas the SCS-diluter systems are designed for light to medium welding processes, the MDB-diluter systems are designed for intensive welding activities with lots of dust load. Both systems come with their own additional benefits. We can help you specify the proper diluter system for your application. 

Another system we recommend when at-source capturing and welding hoods are not an option is our Push-Pull system. This low-cost modular system extracts the fumes and sends these through the filter. The filtered air then re-circulates back into your workshop through the outlet duct. This system will therefore not only provide you with a cleaner workplace, but the system will also help you save costs as your energy consumption decreases.


Extraction hoods

The FlexHood is an extraction hood that has been designed to isolate your welding place. It is a modular extraction hood that is especially suitable for robotic welding applications. This system will reduce the number of toxins in the air and ensure that sparks and spatter stay inside the hood, protecting other people working nearby. 

Ships have never been so technically advanced and so safe as they are today, thanks to the thousands of workers who are committed to providing the world with well-constructed ships. All the more important to take good care of them.
