EIJI AIR COMPRESSOR MFG. CO., LTD.

Single-switch selection of Intermittent or Continuous
operation, Equipped with Ace Controller

GK Series

Efficient, Economical and Dependable... Onecompressor, double the function. A single switch
allows selection of either continuous orintermittent compressor operation, so there's noneed to choose a compressor for just one
particular application.
When used in the intermittent operation mode,
starting and stopping are smoother because thecompressor stops and restarts after idle runningin an unloaded state.
The unloaded state of GK Series compressors
during intermittent operation reduces oilconsumption and significantly improves thedurability of most parts, resulting in lower
operating costs.
Stopping in an unloaded state means there's nosudden sound of air discharge typical of
conventional intermittent-operation compressors.

The specifications of GH-15BK, GH-22CK, and GK-150D is based on IE1 motor.
● The specifications of GK-37A, GK-55D, GK-75D, and GK-110D is based on IE3 motor.
●What's an ACE Controller?
Advanced Controller for Economical Operation
An ACE controller combines the functions of an unloader pilot
Selectorvalve and a pressure switch to allow one-touch switching betweenswitchcontinuous and intermittent operation. It also functions as aSafetystart/stop switch.
valve
When the pressure setting was reached in previous models
during intermittent operation, activation of a pressure switch
immediately stopped the compressor, exerting a strain on themoving parts and causing partial overheating, leading toexcessive wear. In the GK Series with the ACE controller thecompressor idles (in a no-load state) for 40 to 50 cycles before
stopping, giving the cylinders and other parts a chance to cool
down and allowing the moving parts to come to a smooth stop.
Starting is also smoother, further reducing piston ring and bearingwear. The result is longer component life and enhanced durability.

What's the difference between
a Single-stage and 2-stageCompressor? (GK-37A〜150D)
Unloaderpilot valve

Pressuregauge

Single-stage compressor draws in air andcompresses it all at once to the pressure setting.
2-stage compressor first compresses the air toan intermediate pressure and cools it in a
low-pressure cylinder, then compresses it to thepressure setting in a high-pressure cylinder.
When air is compressed it becomes very hot,wasting energy and causing deterioration andcarbonization of the compressor oil. Air does not
get as hot in a 2-stage compressor, so thetemperature of the discharged air is lower andless oil is consumed. Operating noise is also
reduced.

How to obtain maximum performance from an Air Compressor

The life and performance of an air compressor are greatly affected by the conditions in the location where it is installed. For this reason,
it is important to follow the guidelines listed below to ensure long and efficient operation.
(1) In locations where there is a large amount of dust, clogging of the filter
will lead to a reduction in air delivery, wear of the cylinder, and a shorter
bearing life. Select a location where there is little dust, low humidity, andgood ventilation. Also select a location not exposed to direct sunlight or
rain, and where the ambient temperature does not exceed 40℃. As theambient temperature rises the discharge temperature will also rise,leading to an increase in oil consumption and shortening the life of thevarious compressor components.

Notice(1) The Air delivery value indicated is the amount of air delivered at
maximum pressure, expressed as an equivalent at intake air pressure(atmospheric pressure).

(2) The noise values indicated are measured at a distance of 1.5 m from thefront of the compressor running under full load in an anechoic chamber.

(2) Install the compressor on a flat, stable surface. If the installation
location is uneven, it will cause vibration. If necessary, use awedge to adjust the compressor so that it is level.

(3) Allow sufficient space around the compressor to perform
inspections and maintenance. There should be a clearance of atleast 30 cm between the compressor and any walls around it.

(3) The allowed ambient temperature range for operation is 2℃ to 40℃.
(4) Do not use compressed air for devices with direct air intake forrespiratory organs.
