Company founder

ILD was established in the first six months of 1990 as a company owned by a natural person; the company was named “ILD – ekologie ovzduší” - ("air ecology"), although company employees have dealt with the respective scope of activities, i.e. industrial filtering, since the beginning of the 1980s. In the specific atmosphere of social changes at the end of the 1980s and beginning of the 1990s, characterized by impending privatization of national and other companies, cooperatives etc., the founder of ILD-Air Ecology provided employment to the workers of the former socialist company. The company's offices were in Prague 6 during the first stage of its existence. A fabric hose filter with pulsed flushing adjusted using compressed air was developed there and named “Alfa-Jet”.
It was very difficult to launch the product due to the lack of references. Despite these difficulties the launch was successful and now there are over 500 locations equipped with these filters in the Czech Republic as well as abroad.
After handling the tasks, further offices for the design department were rented in 1993 – 1995 and in 1993 an older production plant of the former producer cooperative, Kovopodnik in Kladno was purchased from the beneficiaries of restitution. That same year, the employees were transferred to the newly established limited liability company named ILD – Air Ecology, s.r.o.
A branch of ILD Air Ecology, s.r.o. was established in Vsetín in order to produce electronic devices and control systems for filtering.
In the second half of the 1990s, the affiliated company of ILD SK, s.r.o. was established in Košice and the Prague offices were closed. At the same time the company management passed from ing. Luděk Dembovský, Sr. to his son ing. Luděk Dembovský, Jr.

In order to ensure better the possibility to monitor economy, the production in Kladno was separated from the engineering and design activities. In February 2000, the production became an independent company named ILD-Kovo, s.r.o., changed in 2001 to ILD cz, s.r.o.

During 2001 – 2007 the employees of designing, implementation and production of controlling systems were gradually re-transferred from ILD Air Ecology to ILD cz, s.r.o.

At the beginning of 1998, DUST Service, s.r.o. with its registered office in Vsetín was established to provide servicing, repairs and maintenance of filter installations and FILTEX, s.r.o. was established in Košice at the end of the 1990s to provide the production of filter hoses.

All the above-mentioned measures were thus used to create a structure that is stabilized and provides work in filtering industrial waste gases to the full extent of the investors' needs.
In the 1990s many business subjects were established in the respective industry. At present many of them no longer exist, however ILD with all its bodies has proven perfect viability and at present it is experiencing rapid development with its premises expanded, new buildings built and modern production machinery bought and put into operation.
From the original approximately CZK 25 million in 1990-91 the turnover has increased to several hundred million Czech crowns and there is still a growing tendency. The range of engineering activity in investment production is increasing, the range of products in purifying industrial gas is expanding and the quality of the implemented equipment is growing intensively.
