Filtration
VMAC rotary screw compressors are designed and machined to exacting
tolerances. Foreign particles entering the compressor can damage system
components such as seals, bearings, rotors, as well as the inside of the
housing, resulting in performance losses and reduced system life.
The system is equipped with a replaceable paper element inlet air filter, spin
on high pressure oil filter and a spin on coalescing filter.
These system filters enhance performance and extend component life by
reducing damage from dust and other debris. Proper maintenance is required
to
maintain system performance and extend the system’s life.
Compressor Drive, Belt and Tensioning
The compressor is directly driven by a 4 rib belt. Anytime the engine is
running the compressor is running. The system has an automatic belt
tensioner, manual adjustment is not required.
Pressure Regulation
Pressure regulation is achieved with a combination of an inlet valve regulator,
a mechanical unloader valve and a discharge valve. Use a Filter Regulator
Lubricator (FRL) to regulate downstream pressure to the tools.
System Pressure Unload
Internal system pressure is controlled via a mechanical unloader valve. When
downstream air pressure reaches 150psi (air pressure to the air tools), the
mechanical unloader valve activates and sends a signal to the mechanical
discharge valve to open. When open, the mechanical discharge valve sends
internal system pressure (pressure inside the compressor and WHASP Tank)
to the inlet valve and closes the compressor air intake poppet. Internal air
pressure is then vented to a nominal value which reduces the load on the
engine. This allows the control system to reduce engine speed which
improves fuel efficiency, as well as reducing emissions and wear and tear on
the system. When downstream pressure drops below 120 psi, the unloader
valve will
close and “load” the system, allowing it to build air.
Engine Speed Control
The engine speed is controlled mechanically by a pneumatic throttle which
raises and lowers engine rpm according to air demand. Operator input is not
required on the throttle lever.
Spark Arrester
The gas engine is supplied with a spark arrester.
For more information regarding the spark arrester, refer to the Honda GX390
O
wner’s Manual supplied with the system (VMAC P/N: 1901066).
