Flow Torch 600s ->

The Flow Torch™ 400 is an open coil air heater designed for high flow rates at low pressure drop due to its efficient design with minimal flow restrictions. The robust construction of this 4” diameter stainless steel heater offers reliable long-life performance and reduced operational cost.

The Flow Torch™ 400 incorporates a spiral wound element of the highest grade material, providing quick heat up and cool down cycles with maximum heat transfer.

The Flow Torch™ 400 is capable of operating with airflow of 500 SCFM and a maximum operating pressure of 3 PSIG*. Maximum output temperature is 482°C (900°F).

All Flow Torch Heaters are UL recognized components under UL file number E365755.
Regenerative Blowers available with complete systems.

* Note: minor leakage through stranded leads
