8.5 GENERAL DESCRIPTION
The compressor is an electric motor driven, oil free, two
stage screw compressor, complete with all necessary
components piped, wired and baseplate mounted. It is
a totally self contained air compressor package.
The standard compressor is designed to operate in an
ambient range of 1.7
_
C to 46
_
C (35
_
F to 115
_
F). The
standard maximum temperature of 46
_
C (115
_
F) is
applicable up to an elevation of 1000m (3280ft) above
sea level. Above this altitude significant reductions in
ambient temperature are required if a standard motor
is to be used. Some models have more strict limitations
on the maximum altitude/ambient at higher operating
pressures. Consult engineering or the engineering data
pages for specific guidance.
The compressor is managed by the onboard electronic
controller. The controller and drive system operate
together to vary the speed of the compressor to deliver
compressed air at the target pressure.
Panel instrumentation is provided to indicate the
compressor operating conditions and general status.
Air is pulled into the machine by the cooling blower and
through the heat exchangers (for air cooled).
By cooling the discharge air, much of the water vapor
naturally contained in the air is condensed and is
drained from the built–in moisture separators and
drains.
The oil sump and pump are integral within the gearcase.
The oil pump is a positive displacement gear–type
pump, and is driven by the motor/bullgear shaft. The
gearcase is vented to a mounted breather. The breather
exhaust is piped to the top of the package.
The compressor is provided with temperature sensors
which will shut the unit down in case of excessive oil or
air temperatures.
Effective oil filtration is provided by the use of a screw
on, heavy duty oil filter.
NOTICE
Nirvana air compressors are factory filled with SSR ULTRA COOLANT which is designed to operate for 8,000
hours or two years, whichever comes first.
The oil must be changed at these intervals to avoid breakdown and equipment damage.
