On December 21st 2022, we could at Gram Clean Air A/S celebrate the company's 80th anniversary, a milestone in the company's history, which we celebrated internally on the day and during the new year 2023 we will mark it with customer activities.

Since the start of the company in Haderslev in 1942 under the name V. Aa. Gram with the production of piston rings, a enormous development has taken place. On the product side, several models for the improvement of the physical working environment are now being offered. At the same time the company is managed in third generation of the Gram familiy: After the founder Mr. Vagn Aagesen Gram, Mr. Sven Gram developed the first working environment prodocts and took over the management at the same time. Later it was the brothers Mr. Henrik Gram and Mr. Morten Gram, who were at the helm, while the company grew, and since 2020 Mr. Morten Gram has been the sole owner. In 2022, the company changed its name to Gram Clean Air A/S.

We are proud to celebrate the anniversary and look forward to many more years of further development and cooperation with existing and potential customers!
