Konesko Põltsamaa welding ventilation for three welding booths
At Konesko's Põltsamaa factory, we installed welding ventilation for three welding booths located in the centre of the production hall, while preserving the crane's movement within the worktable area. For each booth we created an independent Push-Pull solution that uses a single shared Gram Clean Air FL-series welding filter. "Smart" plugs activate the ventilation only during welding, thanks to which there are no heat energy losses and the system does not run throughout the entire working day.


Project Challenge
The welding booths were located in the centre of the production building, and in each booth it was necessary to maintain crane movement within the workbench area. For this reason, a conventional solution could not be used, and an individually tailored solution had to be developed to meet the client's needs.
How We Built It
We created an independent Push-Pull solution in each welding booth, using a single shared welding filter. Since this was not robotic welding, we added "Smart" plugs to control the operation of each booth, which activate the ventilation of a specific booth during welding and stop working once all welding fumes have been extracted. This way, the system starts and stops automatically according to the welding, so it does not run throughout the entire workday, and the filter does not operate at full capacity when there is no need for it.
- Independent Push-Pull solution in each of the 3 welding booths
- One shared welding filter: Danish manufacturer Gram Clean Air FL series
- "Smart" plugs for automatic control of each booth
What We Achieved
- No heat energy losses — all cleaned air is directed back
- The system starts and stops automatically according to the welding
- The filter does not operate at full capacity without need
- Maintained crane movement within the workbench area in all three booths
- The system can be expanded in the future

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.
