Flame Arresters
Oberland Mangold flame arresters are made from high-alloy, corrosion-resistant metal foil strips, and thanks to precisely adjusted gap widths, they provide maximum safety with minimal pressure loss. They are used in areas where explosive gas-air mixtures are present, such as marine gasoline engines, combined heat and power plants, and tank systems. Our flame arresters also offer the highest safety in hydrogen applications due to specially adapted gap widths.
Applications:
Explosion
| Explosion Group | Max. Standard Gap Width [mm] | Reference Gas Mixture |
|---|---|---|
| IIA1* | ≥ 1,14 | Methan |
| IIA | > 0,90 | Propan |
| IIB1 | ≥ 0,85 | Ethan |
| IIB2 | ≥ 0,75 | Ethan |
| IIB3 | ≥ 0,65 | Ethan |
| IIB | ≥ 0,5 | Wasserstoff |
| IIC | < 0,5 | Wasserstoff |
