Supply hose with pressure gauge
As is well known in the field of compressed gas, inflating a balloon by
connecting it directly to the cylinder of gas charged to 200 atm (atmospheres),
besides being not regular by law, may pose a risk to the operator. It is always
advisable to use a pressure reducer able to lower at the right value the
pressure delivered from the cylinder. In the field of aerostatics the cylinders
are of 40 liters or 50 liters with internal pressure of 200/230 Atm, a
considerable value, therefore the operator's attention during inflation is
essential for safety at work. TecnoFly 2008, always sensitive to security needs,
offers a supply hose complete of professional reducer with standard connector
for helium cylinders, for inflating balloons as the TLB 180 and the Balloon
Photo System, and in general all aerostatic balloon to be inflated with helium.
Thanks to this reducer the pressure in the valve is reduced from 200 to 6
atmospheres avoiding dangerous "whiplash" when disconnecting the hose from the
ball. The hose is available in different lengths and can be used for many types
of valves, such as shown in the photos. It is possible to take the hose with or
without pressure gauge, depending on your needs. Our hoses work with the
"push to inflate" system, that folding in any direction the hose in the vicinity
of the metal joint, it activates the valve. Contact us for a quote, we are at
your disposal for any clarification. TecnoFly 2008 distributes only quality products.
How to read the pressure gauge
The industrial cylinders of helium gas in commerce are filled at a pressure of
200 atm (atmospheres), which is about 3000 psi or 200 Bar. A pressure gauge
usually has two scales of measurement in the indicator, usually there are gauges
with scale in Atm and Psi or Psi and Bars. When the cylinder is full, the gauge
must score 200 atm, or about 200 bar or 3000 psi. The capacity of a compressed
gas cylinder is expressed in cubic meters or in liters. Here is a table to clear
up any doubt about the choice of the cylinder to be used.
