1 7.0/ RL 0: neumaic volume-flow conroller How energ efficienc is improved For demand-led conrol of he air volume in office rooms. Areas of applicaion Conrol of he suppl and exhaus air of individual rooms or duc pressures. Can be used in poeniall explosive areas. Feaures Suiable for use in areas a risk of explosions in zone G Conformi esed as per EN - and EN 7- (Ex zone G ) Conrol of consan, swichable or variable air volumes Saic differenial pressure sensor wih large measuring range (0 o 50 a) Conroller fron panel is prined wih circui diagram for rapid idenificaion of funcion hermoplasic housing suiable for wall or op-ha rail mouning (rail EN 075 ) Compressed-air connecions wih Rp /8" female hread Low-pressure connecions in form of sepped nipples for flexible plasic hose (inernal Ø and mm) echnical descripion Suppl pressure. bar ± 0.
