Rewa manufactures point smoke vents, smoke vents in continuous rooflights, ventilation flaps, light strips and both pneumatic and low-voltage electric smoke-ventilation control systems in Podkarpackie. It holds CNBOP-PIB świadectwo dopuszczenia 5566/2024 for a pneumatic control panel for fire-protection equipment in smoke and heat control systems, valid to 2029 according to the register — pneumatic release units for natural smoke ventilation being its distinguishing product. The firm supplies complete gravitational smoke-ventilation systems comprising vents, curtains and inlet-air openings. Its website does not publish EN 12101-2 classification data, so the CNBOP świadectwo is the certification evidence relied on here.
