Air jet fans, or colloquially, “jet fans”, are used in a stream ventilation for a delivery of polluted air, for airing and for smoke removal as well. They are produced in different sizes: diameters 315, 355 and 400 mm. Klima Celje Jet Fans can be either monodirectional or reversible - hence they work either back or forth, depending on the need. Two-pole motors are used in most of the jet fans thus giving a very low noise level performance while airing. On fire protection systems, F300 and F400 Klima Celje certified fire protection jet fans are used, according to PN-EN 12101-3. All products offered by Klima Celje are CE-marked and are subject to a quality control procedure acc. to ISO 9001.
