1-9.About the pressure resistance of the Air Blow Heater

The withstand voltage of the Air Blow Heater is 0.3MPa for the H series and 0.4MPa for the S series. We can also manufacture the Air Blow Heater with higher withstand voltage by custom specifications.
The discharge pressure displayed by the air compressor is unlikely to be directly applied to the hot air heater. This is because pressure loss always occurs in the process of supplying compressed gas from the compressor to the hot air heater.
For example, if you throttle the flow rate with a flow control valve, the pressure will drop. The pressure loss in piping is reduced from large diameter to small diameter (or vice versa) in different diameter pipes or bent pipes such as elbows.

The definition of the withstand voltage of a hot air heater indicates that it operates normally, and does not mean that the gas does not leak completely.
The power line of the Air Blow Heater often uses a glass-coated wire, and when high pressure is applied, some leakage will occur from the gap in the glass coating. More specifically, since the power line uses a twisted wire, a slight leak will occur from the gap of this twisted wire (a structure in which thin copper wires are bundled).
If the heated gas is the air, the air inside the air will leak, which is extremely safe.
Also, if the heated gas is nitrogen, air can be defined as a gas with 20% oxygen and 80% nitrogen, so it is also extremely safe.

This leak is a small percentage of the amount of compressed gas supplied to the Air Blow Heater and is usually negligible. It can be manufactured as a custom-made specification for special applications where even a slight leak can cause problems.
