Vents shows its "Quiet" bathroom fans with the slogan "... cichszy niż szept" on display cards, next to a board of domestic extract fans. Below them a compact heat recovery unit stands with its panel removed, revealing the cross-flow exchanger, filters and fans. The blue cloud-map backdrop lists ventilation units, fans and grilles in Polish.
