Specifications subject to change without notice or incurring obligation 15 15.1 6-29-05 VTR-1 Features & Benefits • Low Cost Simple design results in low cost. No moving parts to wear means no maintenance costs. No maintenance means no down time costs. • Adjustable Control vacuum level by adjusting air supply pressure. • Compact Allows you to locate the vacuum generator at the point of application for highest efficiency. • Quiet No vanes, pistons or motors. • Safe No moving parts, safe in hazardous atmospheres. • Efficient Air consumption: 4.8 SCFM @ 80 psi inlet. Vacuum level: 28 in. Hg @ 80 psi inlet. Standard Specifications Glossary of Terms • Air Consumption The volume of compressed air, per unit time, required to operate the vacuum generator; measured in standard cubic per minute (SCFM). • Air Supply Pressure Pressure of the compressed air at the supply inlet of the vacuum generator; measured in pounds per square inch (psi). • Time of Evacuation The time required to evacuate a given system from atmospheric pressure to a specified negative pressure (vacuum level). • Vacuum Vacuum exists when atmospheric air is removed from a system, resulting in less pressure within the system than the atmospheric pressure outside the system. • Vacuum Flow The rate at which atmospheric air moves out of a system is defined as the vacuum flow rate and is expressed in standard cubic feet per minute (SCFM). • Vacuum Level The level of negative pressure is defined as vacuum level and expressed in inches of Mercury (in. Hg.). Model VTR-1 Materials: Aluminum, black anodized and Brass Weight: 2.1 oz. 0 2 4 6 8 10 12 14 16 18 20 22 24 26 28 10 20 30 40 50 60 70 80 Vacuum Level in.
