On Torch Welding Fume Extraction – The mobile filter unit OTS has been designed by Aerservice Equipment’s to safeguard the health of welders by capturing pollutants directly at source through the use of fume torches. OTS has an automatic cleaning system studied to ensure maximum performance of cartridge cleaning, and an automatic Start & Stop function is included in all models.

LEV fume extraction Unit is available in 230Volt Single Phase for 1 torch or 400 V Three Phase for 2 torches.  Maximum hose length 5 metres

Not suitable for the use in potentially hazardous work areas.

WHATS INCLUDED IN THE PACKAGE in the On Torch Welding Fume Extraction

• OTS fume extractor unit on casters
• 5m  fume extraction hose   (2 for 400V unit)
• Hose Connector  (2 for 400V unit)

Price does not include the fume extraction torch.

Structure of the On Torch Welding Fume Extraction

The OTS has a cabinet in powder-coated steel with 4 robust castors and 2 handles. A filter inspection door with key for safety lock allows an easy maintenance of the filters, while the control panel with main switch and user interface allows to monitor the machine’s key functionalities. The inverter provides a fine adjustment of the extraction capacity. The high-pressure extraction takes place thanks to the side channel blower placed downstream of the filter stages, traversed only by clean air.

Filter section of the On Torch Welding Fume Extraction

The filter section is composed of 2 stages:

• -Polyester cartridge filters, cert. BIA “M” (99% efficiency), with quick bayonet coupling;
• -Active carbons filter (1,5 kg) for deodorizing and filtration of VOCs (useful in case of stainless steel, galvanized steel, chrome TIG…).

A spark trap is located upstream of the filtering stages.

Health Risks Associated with Welding Fumes

Exposure to welding fumes can have both short-term and long-term health effects. Short-term effects can range from irritation of the eyes, nose, and throat to symptoms commonly referred to as “metal fume fever.” This condition is characterized by flu-like symptoms such as fever, chills, cough, and muscle pain, which usually disappear within a few days.

Welding fumes are a complex mixture of metallic oxides, silicates, and fluorides. When these fumes are inhaled, they can penetrate deep into the lungs and enter the bloodstream, causing systemic effects beyond the respiratory system. In addition to the immediate symptoms mentioned earlier, exposure to welding fumes can also result in dizziness, nausea, and even neurological effects in some cases.

Short-Term Effects of Welding Fumes

The short-term effects of welding fumes are primarily due to the inhalation of metal particles and toxic gases. The severity of these effects depends on factors such as the type of metal being welded, the welding process, and the ventilation in the workspace. Individuals with pre-existing respiratory conditions may be more vulnerable to these effects.

Furthermore, the composition of welding fumes can vary widely depending on the materials being welded. For example, welding stainless steel produces fumes containing chromium and nickel, which are known to cause allergic reactions in some individuals. Proper personal protective equipment, such as respirators and ventilation systems, is crucial in minimizing the risks associated with exposure to these hazardous substances.

Long-Term Effects of Welding Fumes

Long-term exposure to welding fumes can lead to serious health conditions. Prolonged inhalation of hazardous particles can cause lung damage, respiratory diseases, and even cancer. Certain metals, such as chromium, nickel, and cadmium, commonly found in welding fumes, are classified as carcinogens by organizations like the International Agency for Research on Cancer (IARC).

Chronic exposure to welding fumes has been linked to an increased risk of developing conditions such as chronic bronchitis, pulmonary fibrosis, and occupational asthma. These conditions can significantly impact an individual’s quality of life and may require long-term medical treatment. Employers and workers alike must be aware of the potential health risks associated with welding fumes and take proactive measures to protect themselves from exposure.

The Role of Fume Extraction in Torch Welding

Fume extraction is vital in torch welding to protect the health and safety of welders and those working in the vicinity. By capturing and removing welding fumes, fume extraction systems minimize the risk of exposure to hazardous substances.

Ensuring proper fume extraction in torch welding is not only crucial for the well-being of workers but also plays a significant role in maintaining the quality of the final weld. Welding fumes contain various harmful substances such as metal oxides, fluorides, and ozone, which can not only pose health risks but also affect the integrity of the weld itself. Proper fume extraction helps in achieving cleaner and stronger welds by eliminating potential contaminants from the welding environment.

How Fume Extraction Works

Fume extraction systems typically consist of a hood or capture device, ducting, a filter unit, and an exhaust system. The hood is placed as close to the welding area as possible to capture the fumes at their source. The fumes are then transported through the ducting to the filter unit, where they undergo filtration to remove particulates and gases. The cleaned air is then released through the exhaust system, ensuring a safer working environment.

In addition to the components mentioned, some advanced fume extraction systems also incorporate features such as spark arrestors and pre-separators. Spark arrestors help in preventing sparks generated during welding from entering the filtration system, reducing the risk of fire hazards. Pre-separators are designed to remove larger particles before the fumes reach the main filtration unit, prolonging the life of filters and improving the overall efficiency of the system.

Benefits of Using On Torch Fume Extraction Systems

Using fume extraction systems offers several benefits beyond protecting the health of workers. These systems also help maintain a clean and comfortable working environment by reducing the presence of fumes, smoke, and odors. They can prevent the accumulation of harmful contaminants in the workplace and enhance overall air quality. Additionally, fume extraction systems can help companies comply with regulatory standards and avoid potential fines.

Furthermore, investing in high-quality fume extraction systems can lead to increased productivity and cost savings in the long run. By providing a healthier work environment, these systems contribute to lower absenteeism rates due to health issues related to welding fumes. Moreover, the improved air quality can result in better concentration and focus among workers, ultimately leading to higher efficiency and output in welding operations.
