Dagens Industry Gazelle 2015

We are extremely proud to once again be designated by Swedish newspaper Dagens Industry as one of Sweden’s Gazelle companies for 2015. We have yet again succeeded in doubling our turnover during the most recent three year period and want to take the opportunity to express our thankfulness to our customers and suppliers who have contributed to our success.


Dagens Industry Gazelle is a prize that has been handed out annually since 2000by Swedish Newspaper Dagens Industry to Sweden’s fastest growing companies.

The term Gazelle was coined back in the 1980’s by American David Birch, who was of the opinion that it is smaller, fast growing companies who create the most new jobs. Less than one percent of Sweden’s limited liability companies fulfil the requirement to be called gazelle.

General description of Iris dampers

Iris dampers are specially designed to measure and control the air flow in circular duct systems for ventilation and air conditioning. They are manufactured from galvanised steel and are available in dimensions ranging from 80-800 mm. The adjusting knob and wrench for this are manufactured in plastic. The connection for measurement is found on both sides of the housing for connection of pressure valves. The iris damper is supplied with tables that inform about the air flow in relation to different positions for the iris opening and corresponding pressure levels. They are supplied with rubber gaskets for tight connection to ducts.
