FILLING VALVES AND FILLING HOSES:
It is very important to keep the filling hoses in optimal condition and to replace them
periodically, as required.
We recommend replacing the hoses every two years, or whenever abrasion/scratches are
visible on the hoses or whenever there is rust on the fittings.
You must visually inspect the filling hoses before filling cylinders.
Keep the hoses sheltered from direct sunlight in order to avoid premature aging of the
hoses and keep them at a temperature between 80/-40 °C
.
The minimum radius of curvature must not be less than 400mm.
Do not work on the compressor if it has just been turned off. Wait until the system cools
down completely and check carefully that the fittings are tightened properly when replacing
the hoses.
The filling valve which is used to fill cylinders with compressed breathing
air allows opening and closing the passage of air. This way the pressure in
the whole system remains constant, including the hoses, so as to eliminate
any infiltration of moisture in the hoses, further optimizing the quality of the
breathing air.
Moreover, once the filling operation is completed and you proceed to close
the filling valve, the air under pressure in the filling valve is automatically
blown-off with no need for additional valves.
When you close the filling valve, fully tighten it until all the air is
released.

AUTOMATIC CONDENSATE DRAIN:
The drain of the condensate and oil of the two intermediate separators and of the residual moisture of the final carbon
filter takes place simultaneously and in an automatic manner, through a single exhaust system, which considerably
lowers the costs and greatly simplifies the operation. This allows the operators freedom to dedicate themselves to other
activities while filling cylinders.
Every 6 minutes
(this time interval is the default factory setting but it
can be reset by the operators at a more suitable time interval of their
choice at any time). The solenoid valve opens the flow of air
for 2
seconds
which serves to trigger the pistons connected to the
intermediate separators and the final filter. The solenoid valve is
equipped with a display directly located on it.
The default factory settings are:
DRAIN CLOSED = 6 MINUTES (OFF)
DRAIN OPEN = 2 SECONDS (ON)
These settings can be changed through the electronic control panel.
