F4 Series
Explosion-proof blowers
Explosion-proof blowers are used in areas and applications in which the gases to be conveyed and the surrounding atmosphere present a temporary, long-term, or constant explosion hazard. FIMA machines are ATEX-certified and thus protect plants and especially personnel from dangers.
Zone 0
As world leaders (2010) in Zone 0 blowers, we are aware of the high risk associated with the conveyance of continuously explosive gases. In the conveyance of gases in Zone 0, the plant is constantly exposed to an explosion hazard. Thus, in light of this explosion hazard, safety is one of the most important aspects of our blowers.
Our machines have type approval for explosion groups IIA, IIB, and IIB3. We cover T1–T4 temperature classes for the gas–air mixtures. Our blowers can be found in tank terminals as well as loading, exhaust air combustion, wastewater treatment, and flaring and landfill gas plants, among others..
Zone 20
In contrast to Zone 0, Zone 20 covers areas in which explosive atmospheres made up of dust–air mixtures are present constantly, for long periods, or frequently. In cases in which the explosive atmosphere contains combustible dust, a higher risk level must be assumed.
Prescribed measures for tertiary explosion protection (limiting the impact of explosion) actually exclude the use for blowers for conveying Zone 20 atmospheres. The Zone 20 blowers developed by FIMA are based on Machinery Directive DIN EN 14986 and defined requirements of a notified
approval body. They are used as conveying blowers, e.g., for conveying carbon black.
