A torch with fuel gas forced feed and air inflow from
atmosphere. Designed for fusing bituminous roll material
while roofing and waterproofing work also it can be used
for the drying of casting molds.
The air-gas injection torch «DONMET» 231, hereinafter referred to as the torch, is designed for heating of ferrous and non-ferrous metals and non-metallic materials to the temperature point of 300°C as well as for the flowing of bituminous rolled material during waterproofing of various structures.
The torch is also used for heating plastic tubes before bending, drying concrete panels and brickwork.
Used gas fuel: propane-butane (Р), natural gas, methane (M).
The torch basic parameters conform with ISO 9012:2011.
