Frapol makes air handling units at Kraków alongside a substantial fire-ventilation line: PD smoke-extract duct systems, the KDF smoke vent, fire-ventilation dampers and the Franec RC differential-pressure system. The PD duct system is published at fire-resistance class E600 120 single and CE marked to the harmonised standard PN-EN 12101-7 on a certificate of constancy of performance, with large-format sizes made under ITB-KOT-2019/0955. The Franec RC pressure-differential set is covered by ITB-KOT-2019/1124, and CNBOP-PIB świadectwo 5428/2024 covers its FR-TZS control and supply panel for smoke and heat control systems. The company was formed in 1990. Note that its site returns an error to automated fetching while serving normally to a browser.
