Air Duct Training System Model RAC 031

Air Duct Training System Model RAC 031

Air Ducts are used in many areas. They are used to ventilate offices, sports halls, production halls, conference halls etc. These systems consist of an air duct system and often other facilities for the conditioning of room air. There may also be elements for air purification or sound insulation, e.g. filters. Sci-tech Air Duct Training System Model RAC 031 examines how the air can be distributed in a building. The air duct system is supplied via a speed-controlled fan. The trainee constructs variable air duct systems from commercial components, such as pipes, bends, branches, filters and outlet valves. Connections for pressure measurements can be installed at any position.

Item Description

The effects of the individual components on the pressure loss and thus on the velocity and flow rate of the air are examined. For this purpose there are two manometers with different measuring ranges and a manual device for measuring the air velocity. The fan characteristic is also determined. To determine the power consumption of the fan there are a voltmeter and an ammeter. The well-structured instructional material sets out the fundamentals and provides a step-by-step guide through the experiments
