Description

ROL and ROL-S form a completed unit for installation and control, which is equipped with a cool slide rail type installation rail. The supply contains connector fittings and an end with a measurement fitting. The smooth surface is very easy to keep clean. The ROL nozzle channel supply air jet drags along a large amount of surrounding air, which means a large air mass is moving at low speed.

The adjustment unit ROL-S, which has very good resilience, can be adjusted accurately. The measurement is based on the pressure difference over the control unit. By using the combination of ROL and ROL-S an accurate, low noise and even air distribution is obtained. ROL-S also effectively suppresses the air sound radiated through the ducts.
