Dafo Brand is a Swedish family-owned fire protection group at Tyresö outside Stockholm, supplying gas, aerosol, water-mist, oxygen-reduction, kitchen and marine suppression systems alongside service and inspection work. It appears in SVEBRA’s public competence register as employing certified röklucketekniker under SVEBRA 2023:2, the Swedish personal certification for smoke-vent technicians, which is the third-party evidence relied on for this listing. Two other claims were checked and are not relied on: its own site states EN 12101-2 approval for its smoke hatches without naming a class, body or certificate number, and its stated SBSC gas-suppression certification does not appear against its organisation number in the live SBSC register, so it may be lapsed or held by a related entity.
