Welding Fume Extraction: Diluter Systems

When and where are Diluter Systems practical?

 

41% of workplaces* reported that a welding fume haze is visible in the morning before any welding has been conducted.



While this can be the result of not using engineering controls at all, it can also occur due to the wrong engineering control being used. At source fume extraction such as hooded capture or on-gun fume extraction is not always suitable.

 

 

Diluter systems are the ideal solution for welding fume extraction when at source fume extraction is not feasible or practical.

 

A diluter system is a stand-alone general filtration system that is specifically developed to reduce and control the background concentration of heavy welding fumes in your workshop, helping to reduce exposure to below the new legal limit.

 

 

How does it work?

 

> Polluted air is continuously removed from the environment and filtered.

 

> Clean and filtered air is continuously injected into the workshop to dilute the background concentration of welding fume.

 

> The welding fume haze is instantly removed.

 

> The injection of clean air is completely adaptable to your situation.

 

> The diluter’s filter is cleaned automatically, and residue is collected in a dustbin.

 

 

A flexible stand-alone solution

 

Installing the Diluter system is easy as you do not need any ductwork. This flexible stand-alone solution is great for facilities with multiple welding processes, where locations are changed constantly.

 

This solution can be used in large workshops with various welding processes, changing activities, crane transportation, and locations where ductwork is difficult to install. The result: reducing fume concentration to lower levels, giving a cleaner working environment!

 

 

 

 

Low installation costs

 

The Diluter system consists of three main components: the filter unit, a fan, and the Diluter itself. The Diluter is an air circulation unit with six multidirectional outlet nozzles. The unit re-circulates the cleaned air into the workshop through the outlet nozzles. No ductwork means no ductwork costs!

 

With a Diluter, you will have a relatively small investment for controlling welding fumes in your plant.

 

 

Efficient filtration

 

Filtering and diluting the indoor air provides a healthier environment for all your employees, not just the welders. All staff, such as maintenance technicians, assemblers, machine operators, and team leaders will benefit.

 

 

 

 

The Diluter filters the blue haze instantly making it disappear into the filter medium. Another advantage of cleaner indoor air is fewer dust deposits on your machinery and thus less downtime and lower maintenance costs.
