Does Sierra Precision provide the interface hoses?
No, Sierra Precision does not supply these hoses. Both upstream and downstream hoses that interface with the booster may be purchased from a local, specialty hose fabricator.
What connections are required for interface hoses?
Connections on the booster (both inlet and outlet) are standard ¼” male “AN” flare fittings with a standard 7/16-20 thread. Interface hoses will have the corresponding ¼” female swivel “AN” crimp on flare fittings crimped to a hose such as Synflex 3800 series, or Parker 526BA. Hoses should be rated for breathing air and appropriate pressures (5,000 or 6,000 psi). IDs should be ¼”.
What is the size of the booster?
The booster envelope is 30 ¾” long x 19” wide x 15 ½” high.
What is the weight of the booster?
135 pounds (net), 150 pounds (shipping weight).
What size generator or power source is recommended?
The booster requires a 6 kW power source for mobile applications or a 2.5 kW power source for in-station applications. Larger generators (7.5 kW and up) may be advisable, for mobile applications, in order to run additional accessory equipment (lights, for example).
What inlet air pressure is needed to run the booster?
The inlet pressure required varies depending on the outlet pressure desired. Generally, the higher the outlet pressure, the higher the inlet pressure required. For example, an inlet pressure of 800 psi is recommended to fill 2216 psi SCBAs; an inlet pressure of 2000 psi is recommended to fill 4500 psi SCBAs.
What happens if the minimum inlet pressure required is not achieved?
If the minimum inlet pressure is not met, fill times will significantly increase. If the inlet pressure is too low, SCBA cylinders may not fill at all.
Can the booster be run from ambient air?
No. The booster is designed to boost or amplify an existing air storage system or compressor. It is not designed to perform without minimum inlet air pressure and will prove quite inefficient when used as a compressor.
Can the inlet air source be too high for the booster?
Yes. If the inlet air source is too high, relief valves inside the booster will vent pressure.
How can the booster be mounted or installed?
The booster can be mounted on a sturdy cart, solid workbench, or specially constructed frame over a bank of cylinders. It is advisable for safety reasons, though not imperative, that the booster be bolted to the supporting surface. For mobile installations, bolting to the supporting surface is strongly recommended.
Where can the booster be installed?
The booster should be located in an area that will allow a minimum of ten inches of space between the back and right side of the booster and any adjoining wall or equipment. This clearance is necessary to allow adequate airflow through the booster to cool the electric motor and other components. Additionally, having space in the back of the booster will greatly simplify any required maintenance or service.
What maintenance is required?
The booster is designed to be virtually maintenance free. Only normal mechanical system checks are necessary.
