The pad includes a porous material forming an upper surface layer, a non-porous first inner layer adjacent to the upper surface layer, a non-porous layer forming a lower surface

A portable ventilated seat assembly for use by an occupant in a vehicle includes a lay-on pad for supporting the occupant. The pad includes a porous material forming an upper surface layer, a non-porous first inner layer adjacent to the upper surface layer, a non-porous layer forming a lower surface layer and an expanded spacer material between the non-porous layers. The ventilated assembly further includes a fan coupled to the air space between the non-porous layers for ventilating the seat assembly. The ventilated seat assembly allows ventilation and cooling (or reverse flow heating or cooling) for the occupant. The spacer material may have upper and lower netting layers and fibers extending therebetween.

A P.C./PLC, based operator's monitoring and control station, with calibration software, provides fully automatic operation, monitoring, displaying, alarming, and archiving of data to calculate the performance of the test flow sensor(s), provide dynamic constant velocity, and seal integrity monitoring.
