Push-pull welding ventilation as a tailored solution for the Hest Fencing production workshop

Elister designed a custom push-pull welding ventilation system for Hest Fencing's Tartu production workshop, featuring the Danish GramCleanAir ACF cyclone filter. The system starts and stops automatically based on the welder's activity thanks to smart Smart plugs, effectively removes welding fumes, and directs clean air back into the welder's work area. A frequency converter ensures smooth fan start-up and energy-efficient operation.

Push-pull welding ventilation as a tailored solution for the Hest Fencing production workshop

Project challenge

Since welding accounts for a large share of production, an effective solution had to be found to remove welding fumes and ensure clean air in the working environment. The system had to be automated – starting and stopping based on the welder's activity, ensuring energy-efficient operation. It was also important to return clean air to the welder's work area.

How we built it

Before installation, the Elister team created a 3D model that illustrated the operation and layout of the system in the work areas and helped to better understand its impact on the working environment. After presenting the model and consulting with the client, an agreement was reached and the project could successfully proceed. At the heart of the chosen solution was a push-pull type welding ventilation with a cyclone filter from a Danish manufacturer. Smart plugs ensure the precise starting and stopping of the system based on the welder's activity, while a frequency converter enables a smooth start-up and optimal operating mode for the fan with its high starting current.

  • Push-pull type welding ventilation
  • GramCleanAir ACF series cyclone filter (Danish manufacturer)
  • Smart plugs for receiving the start-up signal
  • Frequency converter for smooth fan start-up

What we achieved

  • Effective removal of welding fumes from the working environment
  • Return of clean air to the welder's work area
  • Automatic start-up and shutdown based on the welder's activity – energy-efficient operating mode
  • Smooth fan start-up with the help of a frequency converter
  • A safer and more productive working environment for welders

FAQ

Frequently asked questions

What type of welding ventilation did Elister install?
A push-pull type welding ventilation system was installed, which removes welding fumes and ensures clean air return to the welder's work area. The solution was designed as a custom fit for Hest Fencing's Tartu production facility.
What filter does the system use?
The system uses a GramCleanAir ACF series cyclone filter from a Danish manufacturer. It is the central component of the push-pull welding ventilation solution.
How does the system operate energy-efficiently?
Smart plugs ensure precise starting and stopping of the system based on the welder's work, enabling an energy-saving operating mode. The system starts and stops automatically according to the welder's activity.
Why is a frequency converter used?
The frequency converter enables a smooth start and optimal operating mode for the fan, which has a high starting current. It ensures a soft start for the fan.
How was the project prepared before installation?
Before installation, Elister's team created a 3D model that illustrated the system's operation and layout in the workspaces. After presenting the model and consulting with the client, an agreement was reached and the project could proceed.

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.
