The gas flow path is as follows:
air compressor → drying and purifying device (drying tower A or B) → filter → filling valve for each bottle group (K1, K2, K3) → gas storage bottle group.
The principle is as follows: the filling of the compressor to the vehicle-mounted gas cylinder is completed by manual control through the conversion of filling valves of the cylinder group. The compressor starts to work, when the exhaust pressure reaches about 9MPa, the pressure maintaining valve of the drying, filtering and purifying system is automatically opened, and the gas enters the gas storage cylinder group through the pre-filter, the oil-water separator, the drying tower A (or B), the post-filter, the check valve (DX1) and the filling valve of the cylinder group. The filling pressure is displayed by filling pressure gauges (B1, B2 and B3) of each gas cylinder.

When the compressed air is filled, the method specifically comprises the following conditions (the valves and the switches are not related in the following cases and are all in a closed state):
A. the air compressor injects compressed air into the vehicle-mounted gas storage cylinder:
(1) after the air compressor operates normally, the blow-down valves of the second-stage liquid-gas separator and the third-stage liquid-gas separator are closed in sequence; then, the compressor unloading valve K9 on the operation panel of the operation console is gradually closed, so that the four-stage exhaust pressure of the compressor is adjusted to 35 MPa.
When the four-stage discharge pressure is 35MPa, the interstage pressure should comply with the following table.
| First order pressure (MPa) | Second order pressure (MPa) | Three stage pressure (MPa) | Four-stage pressure (MPa) |
| 0.27～0.32 | 1.64～1.98 | 7.15～8.6 | 35 |
(2) When filling, all the gas cylinder valves are opened.
(3) Filling in groups

B. Filling air into the vehicle-mounted air bottle from the outside:
the outward filling has two conditions, namely, the airplane is inflated; and the other is to charge the gas cylinder on the ground. The method comprises the following steps:
before filling, firstly determining filling pressure (23 MPa, 15MPa, 5MPa and 0.5 MPa) so as to select a filling route, a control valve and a control switch;
checking the gas pressure of each gas bottle group;
pulling out the inflating hose, connecting one end of the inflating hose with an inflating nozzle J2 on the operation panel, and connecting the other end of the inflating hose with an airplane to be inflated or an inflating joint of the airplane;
and opening a filling valve of the gas storage bottle group to be filled with gas to supply gas to the outside.
(1) Filling under 23MPa
And opening a filling valve K1 and a filling valve K5 in the air pipeline in sequence, and sending air to the outside.
(3) Filling under 15MPa pressure
And opening a filling valve K1 and a filling valve K6 in the air pipeline in sequence, and sending air to the outside. The gas in the first gas storage bottle group is fed outwards through the pressure reducing valve JY3 and the air charging nozzle J2.
(4) Filling at 0.5MPa and 5MPa
