A Vallox counter and a blue feather flag reading "VALLOX HOME of FRESH AIR" sit at the PSIW stand, next to open heat recovery units showing their exchangers. The association's wall lists goals including "Szerzenie wiedzy", "Wspomaganie rozwoju techniki" and "Wsparcie rozwoju projektowania". Visitors gather around a laptop at the counter.
