This mobile welding fume extractor is an entry level extractor for the welding of steel and stainless steel.


This mobile unit is based on the mechanical DuraFilter system. It is designed for infrequent to regular dry welding activities.


The MobilePro is a welding fume extractor for professional welders that need a flexible solution.


The PHV is a high-vacuum portable unit the size of a vacuum cleaner. It can be used everywhere, even locations that are not or hardly accessible to stationary and larger mobile units.

Extraction Arms

Our extraction arms enable you to capture fumes at source. We offer a wide range of extraction arms with metal tubes, plastic tubes and hose tubes. The extraction arms are available in various working reaches and can be used on extension booms if extra reach is needed or mounted on rails for virtually unlimited reach.

The fans in the FUA series can be used as a direct mount fan for metal and hose tube extraction arms or as a central fan in small extraction systems. 0.37-2.2 kW (0.5-3.0 hp)


The extraction fans in the SIF series are sound-insulated and designed for use in central welding fume extraction systems or general filtration systems. 3-22 kW


The TEV series ventilation fans are designed for use as central fans in larger systems with multiple extraction points. 0.75-7.5 kW (2.0-15.0 hp)


Portable extraction fan for use in welding operations in vessels and other confined spaces. 0.75 kW

Stationary Filters

Plymovent offers a wide range of stationary units for filtration of welding fumes and dust. Our product offer ranges from filter units for only one extraction arm up to central filter systems used in for example multiple arm systems, cutting tables or general ventilation and filtration solutions.

Mechanical filter for welding fumes and other dry dust. Normally used for light-duty or maintenance applications.


The MDB is a modular cartridge collector, making it possible to tailor the filter system to the requirements of your industrial application. Made for heavy applications usage.


Due to its compact design the MDB-COMPACT is the ideal choice for applications where a filter is needed near to the source of pollution.


The SCS is a central filter system for removing fumes released during welding, cutting and grinding processes in the metalworking industry.

Push-Pull System

Does your facility have problems with large clouds of fumes building up over the metal working area? If so we have a proven solution that will eliminate fumes lingering above the shop floor. Our Push-Pull systems are proven and effective systems which have been installed in top manufacturing facilities around the world.

Push-Pull System

Push-Pull systems can make a significant contribution to your facility, providing you and your employees with a cleaner, healthier and safer working environment.

Multiple arm system

A multiple arm system can extract fumes from a row of welding booths. The advantage is that each arm can be independently positioned so it is located close to the source of the welding fumes. This system is custom-made for your welding school or company and is easy to operate. When the multiple arm system is controlled automatically, it also reduces energy consumption, resulting in faster recovery of investment costs.

Based on our experience, gained over decades working in the air treatment business, we have developed a proven approach we call engineered solutions. This approach ensures clean air in your working environment with a tailor-made, cost-effective and easy operating system. Investing in a Plymovent system is investing in the environment and in your competitive future.

Diluter system

In some cases source extraction and hoods are not an option. Plymovent has therefore developed a general filtration system that can control welding fumes in large facilities: the Diluter system.
