Airtorch® Models MVTA, GTA925 and MTA925 up to 1200°C.

Stay on this page for units less than 15 KW.   Click here for larger power units.

Flanged heaters up to 1200°C.

Fan and blower VTA Airtorch® Models to 1100°C (2012 °F) – see below.


LTA, VTA, MTA, DPF, DPF-DNA and MVTA models are not pressure rated but could be sealed depending on the model.  Only the models begining with a G like the GTA models are pressure rated to the appropriate pressure.

Fans are employed when the drop in pressure of the system is no greater than approximately 50 in. w.c. (50 in. w.c./inches of H20 is approximately 1.8psi.) This condition remains true even when the fan can output large CFM values.  Blowers are considered in circumstances where larger pressure drops are present.
