Pneumatic TDF Bender QTDF
Last updated: October 14, 2026
Pneumatic TDF bending machine for shops with compressed air supply. Fast and simple operation with quick bending action and low energy consumption — the powered middle ground between manual and electric TDF folding.
Technical Specifications
What is a Pneumatic TDF Bender QTDF?
A pneumatic TDF bender forms TDF flanges on duct panel edges using shop compressed air instead of an electric motor. The air cylinder drives the bending action quickly and consistently, with low energy consumption and simple mechanics. For shops that already run air tools and pneumatic equipment, it is the natural powered choice for TDF flange work.
Key Features
- Pneumatic drive — fast, simple operation with quick bending action
- Low energy consumption: runs on shop compressed air, no large motor
- Four widths: 1300, 1500, 2000 and 2500mm
- Bends 0.5-1.0mm material up to 90 degrees
- Compact machine, simple mechanics, minimal maintenance
Manual TDF Folding Too Slow, but an Electric Machine More Than You Need?
Manual folding caps your flanging throughput and varies with the operator. A full electric bender works — but it is more machine, more power and more cost than modest TDF volumes justify.
The QTDF pneumatic bender runs on the air you already have: quick, consistent bending action at 0.5-1.0mm capacity, with simple mechanics and low running cost.
How It Transforms Your Production Line
The Pneumatic TDF Bender QTDF works on a proven principle — here is the step-by-step workflow that makes it possible:
Air Connection
The machine connects to shop compressed air at 0.6-0.8 MPa — no electrical supply beyond the control circuit.
Panel Positioning
The duct panel edge is positioned on the bending line against the gauge.
Pneumatic Bending
The air cylinder drives the bending action — quick, consistent, repeatable.
Flange Complete
The TDF flange is formed to 90 degrees; the panel advances for the next section.
