Three-Stage Atmospheric<br />

<strong>PET</strong>Star-3 reciprocating compressors are designed to meet the<br />

needs of customers with small rotary or inline blow molding<br />

equipment. These customers require an economical and<br />

efficient solution to maximize productivity. Arranged in a<br />

space-saving package, the <strong>PET</strong>Star-3 has single point air,<br />

water and electrical connections for easy installation. The<br />

machine base is also designed with forklift access for<br />

convenient transport. By utilizing a W configuration, access to<br />

all areas is made unobtrusive during maintenance operations.<br />

Equally robust in design and construction, the <strong>PET</strong>Star-3 is<br />

truly a cost effective solution.<br />

<strong>PET</strong>Star-3 Model 310<br />

BENEFITS<br />
