We are a Czech Production Company situated in North Czech Republic (Bohemia) in Chrastava, Liberec region. Our Company has been operating as Vzduchotechnik since 1992, but we were manufacturing various devices and equipment under the name "Liberecké Vzduchotechnické Závody" (LVZ) since 1950.

We have a long tradition in the production and installation of a wide range of industrial air ventilation equipment, which has helped to maintain a clean and healthy environment and also keep a pleasant climate in various workplaces, in the industrial factories, in offices, hotel rooms and sport halls.

Over the 60 years of manufacturing we have gained the knowledge to focus on highly efficient and reliable systems designated for air extraction and filtration for all types of industrial, military and civilian installations. Basic categories of our production range are:

1. Industrial dust exhaustors with three mechanical filtration stages (cyclone separators, automatized units with bag or cartridge filters)
2. Ventilation systems (pipeline and portable ventilators, roof ventilation units, pipeline mufflers and noise suppressors, heating units, shutters and other components of classic ventilation systems)
3. Filtration units (filtration cartridges and filter housings, bag and sleeve filters, stripe filters, clean extensions and special filtration equipment)
4. Electrostatic filters (advanced filtration technology using ionization and electrostatic separation of very fine elements and micro-particles)

We are a medium size company (100 – 130 employees) therefore we can be flexible enough to be able to manufacture custom and standard products or parts on-demand. A big part of our production is delivered as specially modified equipment or as appliances directly designed according to requests of our customers. That is why our catalog rather represents summary of the most frequently used modifications and standards but does not cover our technical limits in full range. Thanks to the wide variety of machinery equipment we are able to design and produce any utility item or construction made of all usual or common metals under very reasonable conditions. Full production range of our company has been certified according to the latest ISO 9001 standards.
