What Is the xTool Air-Compress Assist?
The xTool Air-Compress Assist is an industrial-grade air pump that delivers a powerful 30L/min of terminal airflow directly to your cutting surface. Unlike standard diaphragm-style pumps (which can lose more than half their airflow due to deformation), this upgraded metal piston pump ensures zero air transmission loss. The result: true, consistent airflow at the nozzle for maximum performance.
Key Features of the xTool Air-Compress Assist

Upgraded Metal Piston Pump
- Traditional pumps use rubber diaphragms that weaken and restrict airflow.
- The xTool model uses an industrial-grade metal piston, eliminating airflow loss and delivering a consistent TRUE 30L/min output at the terminal.
- This means you’re actually getting the airflow promised, not half of it.
Cut Cleaner & 20% Faster
- With high-volume airflow, smoke and debris are blown away instantly.
- Cuts come out with nearly spotless edges, even on wood and acrylic.
- Cutting efficiency increases by up to 20%, saving time and extending machine life.
AUTO Airflow Adjustment
- In AUTO mode, the pump intelligently adjusts airflow depending on whether you’re engraving (low airflow) or cutting (high airflow).
- No manual adjustments needed—just seamless integration with your xTool S1 or M1 Ultra.
- Makes the entire workflow hands-free and more precise.
Cleaner Airflow
- Built-in filtration captures up to 99.7% of smoke and dust, resulting in cleaner output.
- Better airflow also keeps your workspace clearer while cutting thicker materials.
Laser Lens Protection
- Constant, powerful airflow keeps residue off the laser lens.
- Prevents buildup that can reduce accuracy or damage the optics.
- Extends the durability and reliability of your laser machine.
Compatibility
The xTool Air-Compress Assist is compatible with:
- xTool S1
- xTool M1 Ultra
If you own the standard M1 or D1 Pro, you’ll need their respective Air Assist systems.
