Ventilation solutions for the Lacquer Industry

Perfect finish and safety

Achieve a dust-free lacquer finish and minimize heating costs with Technor's ventilation solutions.

Clean air is essential for a perfect finish, but ventilating spray booths is often energy-intensive. Technor strikes the balance. We provide solutions that ensure dust-free air and compliance with VOC and ATEX regulations, while minimizing heat loss and keeping operating costs down.

Quality: The dust-free surface


Dust is enemy number one in surface treatment. Even microscopic particles can require re-lacquering or polishing, costing time and money.



  • Controlled airflow: We design the system with the correct flow (e.g., cross-draft or vertical flow), directing overspray away from the workpiece and ensuring external dust does not enter the zone.
  • Optimal filtration: With pre- and post-filters, we ensure the heat exchanger remains clean and that exhaust air meets environmental regulations before leaving the building.
  • Constant pressure: The control system ensures stable booth pressure, so doors and airlocks can be opened without swirling impure air onto newly lacquered workpieces.

Energy: Recover heat from the cabin.

Heating large volumes of outdoor air to 20-25°C, only to extract it seconds later, is expensive. This is where the greatest savings potential lies.


  • High-efficiency heat exchangers: We use high-efficiency cross-flow heat exchangers that recover heat from the exhaust air and transfer it to the supply air. This can significantly reduce heating requirements.
  • Operation in "Economy Mode": Using frequency converters (VFDs) and automatic damper control, the system can ramp down when the spray gun is not active, or when workpieces are simply drying or curing.
  • Recirculation: Where safety permits (and legislation allows), we can design the system for partial recirculation during the drying process for further energy savings.

From Hi-Fi to large machines

We deliver extraction for everything from fine mechanical lacquering to industrial surface treatment of heavy equipment. Here are three examples of our solutions:

Dynaudio, Skanderborg

Ventilationsanlæg for lakdampe

As a manufacturer of high-end speakers, Dynaudio places extreme demands on surface finish. Even the smallest dust particle in the lacquer is unacceptable on the exclusive cabinets.

Eik Trapp A/S, Norway

Udsugning af lakdampe

Norwegian Eik Trapp produces quality staircases, involving the lacquering of large, irregular wooden workpieces. This requires flexible extraction to capture overspray effectively.

Hydrema A/S

Udsugning af dampe fra spartelproces samt udsugning af maledampe ved blandebord

At Hydrema, large dump trucks and excavators require robust surface treatment that lasts for many years. This calls for large spray booths and massive air volumes.

Safety: ATEX and VOC handling

Lacquer and solvents create explosive atmospheres and harmful fumes. Safety cannot be compromised.


  • ATEX experts: We ensure that fans, motors, and instrumentation in the zone are correctly classified and approved for operation in explosive environments.
  • Fume removal: Effective extraction protects the painter from inhaling isocyanates and solvents, ensuring that occupational exposure limits (OELs) are met.
