INDOOR AIR QUALITY SOLUTION THAT EFFECTIVELY CONTROLS PARTICULATE
Have you ever noticed the formation of a layer of welding fume in the air within your welding and fabrication facility? Fume and metal particulate from metalworking applications such as welding, plasma cutting, arc gouging, and grinding, can form a layer of particulate in your facility that can settle back to the
floor. Lincoln Electric, a worldwide leader in welding fume control, has a proven ventilation solution that dilutes and filters this layer of particulate. Effective welding fume control can significantly contribute to a cleaner work environment and higher productivity.
There are many methods to providing “adequate” welding fume control to protect the worker. However, even with successful implementation of one method of control it may be advisable or even necessary to implement a secondary method of control. For example, when fabricating large weldments, or when the welder needs to shift positions frequently there is greater potential for fume to escape and rise into the air. During the welding process, a plume of gas and particulate is created. The intense heat from the welding arc heats the plume which causes it to rise quickly into the air. Over time a layer of particulate can accumulate in a facility if steps are not taken to control it. Lincoln Electric’s Push/Pull Systems are custom designed to filter and dilute this layer.
Examples of Where or When to Apply a Push/Pull System
- Supplement source extraction for difficult applications.
- Fabricating large weldments or welding on large work pieces.
- The welder needs to shift positions frequently.
- Shops utilizing robotic welding and hard automation.
- Welding locations within a facility are variable.
- Personal protective equipment is used to control the welder’s potential exposure.
- RotaPulsePlus™ Automatic Filter Cleaning System. Each time the system is switched off, an automatic cleaning cycle takes place.
During this cycle the filter cartridges are cleaned by compressed air jets from the RotaPulsePlus™ system. The particulate is deposited in the drum beneath the filter.
- Adjustable Outlet Nozzles. Nozzles can be easily customized for the configuration based on facility layout, welding areas and specific application needs, for increased coverage areas.
- Cleaner work environment: Reduce dust and dirt in operator and surrounding work areas
- Custom engineered to meet facility and application requirements
- Easy installation: Position the filter and fan unit on the floor, a platform or a mezzanine
- Low noise level: Will not contribute to increased noise levels.

FOUR ELEMENTS: EXTRACTION, FILTRATION, FAN, RE-CIRCULATION
1. Extraction (Pull) - To move and extract the layer of particulate in a controlled direction, an extraction duct is designed according to your specific operation and facility layout. The extraction duct is provided with airflow grids. Proper design will allow for the most effective and controlled extraction of the
metalworking particulate in your facility.
2. Filtration - The extraction duct is connected to a self-cleaning filtration unit. As the particulate moves through the extraction duct, it is collected on the filter media which is periodically cleaned by an automated, pneumatic cleaning system. When the pressure over the filter reaches a certain point, the
internal blow back mechanism begins to clean the filter, resulting in the particulate dropping into a collection container at the bottom of the filtration unit. The container can be easily emptied and the collected particulate should be disposed of according to Federal, State and local regulations.
3. Fan - The continuous extraction (pulling), filtration and re-circulation (pushing) process is generated by a fan unit specifically sized for the system and positioned downstream from the filtration unit. To significantly reduce the system’s noise level, the fan is mounted in a sound absorbing enclosure and
powered and controlled by intelligent controls.
4. Re-circulation (Push) - Once the particulates have been filtered, the filtered air can be re-circulated. By re-circulating the air, energy cost savings, specifically in climate controlled environments, can be recognized. The re-circulated air is also used in a controlled manner to dilute and push the layer of particulate towards the extraction duct. To effectively control the direction of re-circulated air, a re-circulated air duct with volume regulated airflow grids is designed according to your specific operation and facility layout.
It is the responsibility of the owner/operator to comply with local codes and regulations regarding the quality of recirculated air. Gases are not removed by the filters.
