5. INSTALLATION
SMACD unit consists of a rotary screw type driven by a diesel engine. Compression occurs when inlet air (at
atmospheric pressure) enters a chamber where it is trapped between the rotating rotor lobes. A lubricated pitch
line provides sealing. As the lobes mesh, they reduce the volume of the air, compressing it to the desired
pressure.
The system has a two-stage air/oil separator. The first separation stage consists of baffles, which perform
mechanical separation. The second stage uses a special separation element, which delivers dry air to the outlet.
The second stage is a spin-on type coalescing filter.
Pressure regulation is achieved by adjusting the pressure regulator valve mounted in front of the compressor
(Silver adjustable valve). The system pressure is pre-set at 150 psi. To reduce the pressure, either adjust the
regulating valve or use a Filter Regulator Lubricator (FRL) to achieve the final tool pressure.
ENSURE THAT THE WATER SEPARATOR IS MOUNTED AS FAR FROM THE COMPRESSOR AS
POSSIBLE AND THAT IT HAS AT LEAST TWO METRES OF HOSING BETWEEN THE COMPRESSOR
DISCHARGE AND SEPERATOR INLET.
The compressor air intake is protected by a paper-type replaceable air filter, and a spin-on type oil filter for the
oil side and a coalescing filter for final oil removal from the air.
Safety features included in the compressor are:
▪
200 PSI relief valve in separation manifold.
▪
Blow-down valve to discharge system pressure on shutdown - will not allow compressor
restart until system pressure bellow 5PSI.
▪
Over temperature safety sensor in the compressor oil.
▪
Over pressure control mounted at the minimum pressure valve.
▪
Do not disable or bypass the over-temperature shutdown circuits. Failure of the
shutdown system could result in equipment damage, injury or death.
A liquid-to-liquid air cooler with thermal bypass valve maintains operating temperatures in an optimal
performance range. This helps to increase system durability and reduces the temperature of the compressed
air.
