Four-Stage Atmospheric<br />
When unsurpassed performance and reliability are required, the<br />
<strong>PET</strong>Star-4 line of 4-Stage Reciprocating <strong>Air</strong> Compressors answers the<br />
challenge. Robustly designed and configured in a horizontally opposed<br />
cylinder configuration, the <strong>PET</strong>Star-4 arrangement virtually eliminates<br />
vibration with a minimal foundation requirement. By utilizing four<br />
stages of compression, the <strong>PET</strong>Star-4 is capable of providing<br />
unsurpassed compressor efficiency. Lower stage compression ratios<br />
reduce the cylinder operating temperatures and extend the life of valves,<br />
rings, and packing. To simplify installation, all <strong>PET</strong>Star-4 units feature a<br />
heavy-duty welded steel sub-base and are available with a matching air<br />
treatment component package. Whether you require a compressor for<br />
in-line molding or capacity to support a large production operation,<br />
there is a <strong>PET</strong>Star-4 package to meet your needs.<br />
