VAD/VAC Series Vacuum Generators & Suction Cup Compatibility Guide

I. Basic Overview of VAD/VAC Series

The VAD/VAC Series is a line of single-stage vacuum generators manufactured by brands such as Festo. Utilizing the Venturi principle, they generate negative pressure via compressed air and are specifically designed for pneumatic vacuum systems.

Model Interpretation:

VAD: Standard type without air pulse function
VAC: Type with air pulse function (for selected brands)
Numbers (16/25/32/40): Indicate the outer diameter of compatible air tubes (mm), corresponding to different flow rate levels. Larger numbers represent higher flow rates and stronger suction force.

III. Suction Cup Compatibility Principles

1. Interface Matching

Connection Methods Between VAD/VAC Series Vacuum Generators and Suction Cups:

Connection Method	Description	Application Scenarios
Direct Push-in Fitting Connection	Vacuum Generator → Push-in Fitting → Air Tube → Suction Cup Connector	Quick installation, easy suction cup replacement
Threaded Connection	Vacuum Generator (Internal Thread) → Threaded Suction Cup / Suction Cup Bracket	Secure connection, suitable for vibrating environments
Adapter Connection	Vacuum Generator → Adapter → Air Tube → Suction Cup	Conversion between different interface specifications

Direct push-in fitting connection is recommended for its simplicity and reliable sealing.

2. Specification Matching

Air Tube Matching: Use air tubes with outer diameters consistent with the generator specifications (16/25/32/40mm).
Flow Rate Matching:
- VAD16/VAC16: Compatible with small suction cups (diameter ≤50mm) for lightweight workpiece handling
- VAD25/VAC25: Compatible with medium suction cups (diameter 50~100mm) for general industrial applications
- VAD32/VAC32: Compatible with large suction cups (diameter 100~200mm) for heavier workpieces
- VAD40/VAC40: Compatible with extra-large suction cups or suction cup groups for heavy-duty handling
Vacuum Level Matching: Ensure the suction cup material can withstand the generator’s maximum vacuum level (-0.095MPa).

3. Recommended Suction Cup Types

Select the appropriate suction cup type based on application scenarios:

Suction Cup Type	Features	Application Conditions	Recommended Matching
Standard Flat Suction Cups (VAS Series)	Fast response, concentrated suction force	Flat, smooth surfaces	VAD16~VAD25
Bellows Suction Cups (VASB Series)	Excellent height compensation, adapts to slight unevenness	Slightly uneven surfaces	VAD25~VAD32
Deep Bellows Suction Cups (Multi-pleated)	Large stroke compensation, adapts to significant height differences	Highly uneven surfaces	VAD32~VAD40
Sponge Suction Cups	Adapts to porous, rough surfaces	Wood, cartons, etc.	VAD25~VAD40
Elliptical Suction Cups	Adapts to long, narrow workpieces	Plates, pipes, etc.	VAD25~VAD32
Custom Suction Cups	Tailor-made for specific workpieces	Products with special shapes	VAD16~VAD40

Note: Materials include NBR (oil-resistant), PUR (wear-resistant), and VMQ (high-temperature resistant). Select based on operating conditions.
