The Auxiliary Air & Helium Supply provides a portable and compact way to operate the bubble generator in any location where air and helium are not conveniently available. This makes it ideal for the study of ventilation patterns, cleanroom airflows and similar applications.
The whole unit is easily disassembled for general cleaning, maintenance or repair.
The air is supplied by a Thomas industrial duty oil-less piston compressor that is designed to provide the required flow rate and pressure to the Console with either one or two Plug-In Heads in operation, so no pressure regulator is required.
The helium is stored in a rechargeable aluminum cylinder. A helium regulator maintains the working pressure of 20 psi. This combination can deliver 10 hrs of continuous running time with both Plug-In Heads in operation, or 20 hrs with one Plug-In Head. The inlet port of the regulator is equipped with a CGA 580 bullet shaped nipple fitting. Since this fitting is the same fitting that is commonly used on larger bottles, it can be used interchangeably. Also provided is a Transfill Manifold which can be used to refill the helium cylinder as needed.
The air compressor and helium cylinder are mounted to base plate enclosed in a heavy duty polyethylene case. The assembly can be removed from the case for general operation and, as necessary, to recharge the helium cylinder.
The provided Trans-fill Manifold is used to refill the helium cylinder from a master cylinder as needed. It comes with a high pressure gauge which indicates the tank pressure. Hand grips on the 580 CGA fittings allow for "tooless" charging of the cylinder to be filled. Once the tank has been recharged, the bleed valve is used to remove the high pressure gas in the supply line.
