Overview

This document provides detailed performance data and dimensional information for the Vtec Vacuum Cartridge Mini Series, including models VC202, VC202P, VC203, VC203S, VC203 DS, and VC203 LS. The specifications are subject to change without notice.

Performance Specifications

Vacuum and Feed Pressure

• Maximum vacuum levels range from 10 kPa (75 mmHg) to 90 kPa (675 mmHg).
• Feed pressures tested include 0.17 MPa, 0.22 MPa, 0.314 MPa, and 0.4 MPa.

Vacuum Flow Rates

• Vacuum flow is measured in Normal Liters per minute (NI/min) at various vacuum levels.
• For example, the VC202 and VC202P models show vacuum flows ranging from approximately 2 NI/min at 80 kPa vacuum to over 40 NI/min at 0 kPa vacuum with feed pressure at 0.4 MPa.
• Higher feed pressures generally correspond to higher vacuum flow rates.

Air Consumption

• Air consumption is provided in NI/min at feed pressures of 0.17, 0.22, 0.314, and 0.4 MPa.
• Values range from about 17 NI/min to 32 NI/min depending on model and pressure.

Evacuation Time

• Time to evacuate a volume to different vacuum levels is given in seconds per liter (s/l).
• Evacuation times decrease with increasing feed pressure and vary by model.
• For example, VC203 and VC203S models evacuate to 10 kPa vacuum in approximately 0.06 to 0.12 s/l depending on feed pressure.

Model Variants and Features

• VC202 and VC202P: Two-stage nozzle with holding plug.
• VC203 and VC203S: Three-stage nozzle with M14 twofold silencer.
• VC203 DS: Three-stage nozzle with M15 direct silencer.
• VC203 LS: Three-stage nozzle with M15 twofold silencer.

Dimensional Information

Dimensions are provided in millimeters (mm) and inches (in), though specific measurements are not detailed in the extracted text. Each model includes dimensional data relevant for installation and integration.

Critical Parameters and Recommendations

• Feed pressure significantly affects vacuum flow, air consumption, and evacuation time; higher pressures improve performance.
• Vacuum level impacts flow rate and evacuation time; lower vacuum levels correspond to higher flow rates and faster evacuation.
• Choice of nozzle stage and silencer type affects noise and performance characteristics.
• Users should select models based on required vacuum level, flow rate, and noise considerations.

Summary

The document provides comprehensive performance data for various Vtec vacuum cartridge models, emphasizing vacuum flow, air consumption, and evacuation times at different feed pressures and vacuum levels. It also highlights the impact of nozzle design and silencer type on performance. This information supports informed selection and application of vacuum cartridges in pneumatic systems.
