source of supply, so that the entire supply source, including all
accessory equipment, can be isolated from the entire pipeline system.
E. Include sufficiently sized and properly constructed storage space for
the gas cylinders with manifold systems. Primary and reserve banks
are required for cylinder gas sources.
F. The medical air compressors and medical vacuum pumps shall serve the
medical air and medical vacuum systems only.
G. Locate compressors and pumps in a clean, relatively cool environment
[i.e., not with steam equipment, not to exceed 38 degrees C (100
degrees F) ambient temperature]. Locate equipment in an area where it
can be monitored regularly.
H. Medical air compressors and vacuum pumps shall be multiplexed with
single receivers. Size compressors and pumps such that 100 percent of
the design load is carried with the largest single unit out of
service. Provide 3 valve bypass at receiver.
I. Air compressors shall be a type that provides "Medical Compressed
Air", as defined by NFPA 99.
J. Design air dryers, filters and pressure regulators for the medical
air system in duplex, each sized for 100 percent of the load, using
duplex twin tower desiccant dryers. Include continuous line dewpoint
monitoring downstream of the regulators and carbon monoxide
monitoring with sample connections on the filters. Locate monitor at
the pump control panel or integral with control panel.
K. Locate the medical air compressor system intake outdoors above roof
level, at least 7.6 m (25 feet) (may be more depending upon
prevailing wind direction and velocity) from any building opening or
other intake, and where no contamination from engine exhausts, fuel
storage vents, vacuum system discharges, particulate matter or odor
of any type is anticipated. Air that is already filtered for
ventilation system use is an acceptable source of air for medical air
compressors. Combined intakes must be sized for no restriction while
flowing maximum intake possible, and provided with an isolation valve
at the header for each compressor served.
L. Combine discharge from each medical vacuum pump into one discharge
pipe, sized for no restriction while flowing maximum discharge
possible, and provide an isolation valve at the header for each pump
served. Exhaust discharge at the highest point of the building, above
and at least 7.5 m (25 feet) horizontally (may be more depending upon
prevailing wind direction and velocity) from any intake, door,
window, louvered or ventilating opening of the building.
