Individual push-pull ventilation for four welding booths

We equipped Markland's four adjacent welding booths with an individually controlled push-pull ventilation solution, using the FL-series welding filter from the Danish manufacturer Gram Clean Air. The system automatically opens and closes the dampers according to the welding process and adjusts the fan operating speed depending on the number of active workstations. The result is efficient extraction, reduced maintenance costs and improved energy efficiency, while preserving the ability to service the jib crane in each booth.

Individual push-pull ventilation for four welding booths

Project challenge

The task was to equip four adjacent welding booths with an individually controlled ventilation solution. At the same time, the capability to service a pillar crane had to be maintained in each booth. In addition, it was important to reduce energy costs and optimise the operation of the system.

How we built it

Each welding booth was equipped with a standalone push-pull solution. In designing the system, we calculated air volumes, velocities and the supply air direction to ensure the most efficient extraction possible and the correct choice of equipment. As the filter, we selected the FL-series welding filter from the Danish manufacturer Gram Clean Air, which is one of the most widely used in its class and was a perfect fit for the project. The automation binds all booths into a single, process-sensitive whole: when welding begins, the dampers of the respective booth are opened, and when welding ends, the zone is closed after the residual smoke time has elapsed. The fan operating speed is controlled depending on the number of active workstations.

  • Gram Clean Air welding filter, FL-series
  • 4 individually controlled welding booths
  • Push-pull ventilation solution in each booth
  • Individual control – dampers open when the welding process begins
  • Automatic closure after the residual smoke time
  • Air exchange regulation according to the number of active workstations

What we achieved

  • Efficient extraction in each of the four welding booths
  • Maintained capability to service a pillar crane in each booth
  • Reduced maintenance costs through optimisation of consumption
  • Better energy efficiency thanks to ventilation regulated according to the number of workstations

FAQ

Frequently asked questions

How many welding booths does this solution serve and can they be controlled separately?
The solution serves four adjacent welding booths, each equipped with an individually controlled push-pull ventilation. Each booth operates independently according to the welding process.
What filter is used in this solution?
We use the Gram Clean Air FL-series welding filter from the Danish manufacturer, which is one of the most common in its class. It suited the project ideally.
How does the system save energy?
The fan speed is adjusted based on the number of active workstations, which optimizes consumption and reduces maintenance costs. This ensures better energy efficiency.
How does the system respond to the welding process?
The automation links the booths into a single process-sensitive whole: when welding starts, the relevant booth's dampers open, and when welding ends, the zone closes after the post-smoking time has passed.
Does servicing the jib crane remain possible after installation?
Yes, the ability to service the jib crane was retained in each booth. This was one of the project's key requirements.

Welding hall ventilation solution with smart remote management

We built a push-pull general ventilation system for the welding hall with two separately controlled zones, ensuring a total air circulation of up to 60,000 m³/h (the requirement was ≥45,000 m³/h) and over 10,000 m³/h of fresh air. We installed two GRAM 364DH double cyclones with 45 kW fans and a C.I.C Jan Hrebec plate heat exchanger with water heating, which reduces heating demand. Compliance of air quality with health protection limit values was confirmed by measurements carried out together with the Health Board, and the entire system is controlled by a single control panel with real-time remote management.

Push-Pull welding ventilation for a metal production hall in Saue

At a metalworking company's production hall in Saue, we solved the blue welding fume problem using the Push-Pull method, as the use of welding arms was not possible due to the large components and continuous crane operation. We installed an FL series filter with GRAM welding cartridges, prepared a 3D piping installation drawing, and carried out the installation. The filtered air is directed into the hall from floor level, and the welding fumes are extracted from above the workstation, beneath the ceiling.

Factory Welding Workshop Push-Pull Ventilation

We upgraded the ventilation of the manual welding stations at Sami Tootmine's Valga factory in two areas, each with 10 workstations. We installed cyclone filters together with fans from the Danish manufacturer Gram Clean Air and designed a push-pull ventilation system with air calculations. We integrated automation that activates the filter system only when welding is actually taking place, ensuring energy savings and a clean working environment. In addition, we helped find a suitable welding filter for the robotic welding area.
