Data - 50 HzPerformance chart4 QQNote : For SN Series, please seek works confirmation prior to finalization of orderFan SelectionThe procedure of estimating the rate of ventilation is to multiply the total interior space by the number of air changeper hour for the respective space given in Fan selection guide.

5 This gives the rate of air movement required in cubicmeter per hour. Thus ventilation on the basis of the air change requirement is calculated as follows :Air movement per hour = length x width x height of the building x recommended air changes per kitchen the best place for the exhaustfan will be in the wall adjacent to, butnot directly above the cooker - the chiefsource of large occupied spaces, the mosteffective ventilation will be obtained,when several small fans are installedinstead of one or two large controlGPN series fans are designed to provide stable speed regulation. Substantial speed reduction is ineviatable accompanied by highrotor loss. The loss reaches its peak at 2/3rd Sync. / RPM.
