1.1 Modular System Standard
Components
System Design
The modular Z MED Medical Air system
consists of compressor modules (duplexed or
multiplexed), a dryer/control module, and an air
receiver module. Each module is fully compliant
with NFPA 99.
Compressor Module
The compressor modules are fully enclosed with
sound attenuated steel panels with full access
doors for maintenance and inspection. Each
compressor module includes the compressor,
drive motor with starter, oil system, and a
compressor control system. The compressor
intake is equipped with an air intake lter and
integral shuto/unloading valve. Unloading
is carried out by closing the intake valve.
Loading or unloading of the unit is controlled
by a pressure transducer which will actuate the
loading solenoid valve. The air discharge for the
compressor module has a pulsation damper,
check valve and manual isolation valve. The
control system will display the runtime hours,
temperature readouts, pressure readouts,
service indicators, safety warnings and safety
shutdowns for the compressor module.
ZR Compressor Drive and Motor
The compressor is a two-stage, oil-free
compressor block, consisting of separate low and
high pressure rotary tooth compressor elements
anged to a common step-up gearbox. The
high and low compressor elements are supplied
with safety relief valves. ZR compressors have
a water-cooled oil cooler, intercooler and
aftercooler. The rst stage air is cooled by an
intercooler with moisture trap and automatic
drain valve. The second stage air is cooled by an
aftercooler with moisture trap with manual and
automatic drain valve. The gearbox oil system
includes an oil sump, pump, oil lter, bypass
valve, drain connection, sight-glass and cooler.
