Ventilation Trainer

This unit consists of:

• A forward curved variable speed centrifugal fan
• Integral control panel together with a rectangular air intake and filter holder
• Ducting components (supplied with the unit to enable parallel branch and line balancing experiments to be undertaken)

Experimental capabilities:

• Examination of typical components, fabrication, installation and assembly techniques used in air handling systems.
• Investigation of pressure losses in bends, branches, changes of section and over straight lengths of duct together with the variation in pressure drop with velocity.
• Determination of the ‘k’ factor for the pressure loss of the above components in each particular configuration.
• Investigation of the fan pressure and volume flow characteristics at various fan speed .
• Examination of standard types of panel and bag filters and their pressure drop against face velocity.
• Measurement of air flow rate using air velocity meter.
