The graphs below can be used for all MHI Airtorch Models.
The standard conditions flow rate (SCFM) vs. Temperature is shown below (per kW). You will be able to calculate kW or SCFM or Temperature if you know two of them. Please see selection tab on left for steps required to obtain kW if not known. Please choose TA class of Airtorch i.e. VTA, MVTA, LTA and MTA when exit temperature is below 925C. Please note that the maximum safe operating temperature for TA models ranges from 850-925°C depending on the model. When the exit temperature required is greater than 925°C please choose the DPF class of Airtorch. Please consult the higher temperature graph (DPF Models) shown below for the DPF models, namely DPF220MP-3, DPF220MP-10.5 and DPFMP220-15.

Tips: The graphs of temperature vs. SCFM/kW above are for air. The position along the SCFM/kW changes with the gas. For nitrogen it is almost the same.
