Construction of one-stream centrifugal fans is adjusted to work in difficult conditions of land and marine industry environment. All products and their equipment are produced according to actual EN norms as well as according to implemented quality norms ISO 9001:2008, ISO 14001:2004 and PN-N 18001:2004.
In standard the fan consists of steel and welded housing, impeller, motor pedestal and base frame equipped with vibration dampers. Presented flow parameters are calculated for medium with 20°C temperature and density 1,2 kg/m3.
All fans are intended for work in ambient temperature range -20°C-40°C; all other temperature ranges demand additional technical agreements.
Equipment in basic execution is intended for work with medium -10°C- 80°C. Fans equipped with cooling disc may work with agent up to 300°C, non-standard executions enable work up to 750°C.
Impellers produced by Nyborg-Mawent are balanced in G6,3 class or G2,5 on request. The fans comply with norms and requirements regarding vibration level according to ISO 14694:2003. Allowable vibration level is specified in fan’s technical documentation. Each finished product is tested in terms of its work parameters.
