🔹Introduction
Conveyors are everywhere in industries — from packaging lines to assembly plants. Most of them depend on belts, rollers, or chains. But what if we could transport objects without any physical contact?
That’s the idea behind my latest project: the Contactless Air Conveyor System. Instead of mechanical parts, it uses airflow to move objects smoothly from one point to another.
🔹 How It Works
The working principle is simple:
- A blower creates a strong stream of air.
- The airflow is directed through a PVC frame and an adjustable guide plate.
- When a lightweight object is placed near the airflow path, it gently slides forward, lifted and pushed by air, without touching any mechanical part.
This makes the system frictionless, clean, and low-maintenance.
🔹 Components I Used
- PVC pipes and joints (for making the frame)
- A blower motor (air source)
- Adjustable acrylic guide plate (for controlling airflow)
- Nuts, bolts, and support fittings
All these are easily available and budget-friendly, making this project great for students and DIY enthusiasts
How do I make this ??
1. Planning & Design
Before starting the build, I did some research on how air conveyor systems work. After going through a few references online, I got a clear idea of how the guiding plate should be designed to control the airflow.
I used Autodesk Fusion 360 to create the design for the guide plate. Once the design was finalized, I sent it for laser cutting to get precise results.
In just 2 days, I got my laser-cut parts.
This step was important because the plate directly affects how the air moves and how smoothly the objects are transported.
2. Making the Frame
Using standard PVC pipes and joints, I assembled the base and vertical supports. This created a stable frame that could hold everything together.
3.Mounting the Blower
The blower is the heart of this system. I fixed it firmly at one end of the frame so that the airflow could be directed in a straight line through the PVC structure
4.Adding the Guide Plate
On the top side, I installed an acrylic plate with bolts and nuts. This plate helps control and guide the air in the right direction so that objects move smoothly.
5.Testing & Adjustments
Finally, I tested the conveyor with lightweight items like paper and thermocol pieces. By adjusting the plate height and blower position, I was able to get a steady and contactless movement
