Heavy-duty, lightweight brass power burner for roofing, waterproofing, preheating and other demanding heating applications. Extremely strong windproof flame for the severest weather conditions. 43.5kW, 3350g/h at 4 bar, 35mm. M20 × 1 thread fits all Pro 86/88 neck tubes. Sievert recommend pairing this burner with the Pro 88 handle (3488) and its gas-saving pilot flame economiser. A 4 bar regulator is required.
The 2943 is the step up from the 2942 in the Pro 86/88 brass power burner range — 43.5kW vs 26kW, with a 35mm head vs 32mm. The windproof flame maintains consistent, controlled output in the exposed conditions of rooftop and open-site work where standard open-flame burners would be disrupted. The external mixing pipe principle gives reliable combustion at both low and full flame settings in all weather conditions.
