Front Flange With Air Barrier; Suggested Air Capacity And Pressure - Videotec NXW Manuel D'instructions

6.7 Front flange with air barrier

The flange with air barrier is equipped with a 1/4"Gas
thread joint and a reduction from 1/2"Gas to 1/4"Gas.
This joint must be connected to the circuit with
compressed air supplied by a compressor.

6.7.1 Suggested air capacity and
pressure
Upstream of the housing , you are advised to install:
• Pressure gauge.
• Adjustment valve.
• Optional filters unit for compressed air cleaning
(NXFIGRU2, filtration 0.1μm).
This allows you to:
• Know and adjust the pressure to supply to the
air barrier.
• Conduct simple maintenance.
Too high pressure values can cause
breakage of the window. Strictly comply
with the maximum values listed below:
Flange with 8 holes with double IR-proof
glass
• System pressure: 4bar max
• Recommended minimum pressure: 2bar
Flange with 32 holes with tempered glass
• System pressure: 6bar max
• Recommended minimum pressure: 2bar

For example purposes, the system pressure-output
pressure and system pressure-air capacity graphics
are outlined which are useful for compressor
dimensioning. All the values must be considered as
purely approximate.
