When it comes to surface preparation, few tools offer the versatility of the Lematec AS118-2C. Whether you're removing rust from a car chassis or etching glass for a DIY project, this tool's unique Dual Feed System adapts to your needs.
Why Choose the AS118-2C? Understanding Dual Feed
The AS118-2C stands out because it allows you to switch between two modes. Knowing when to use which mode is key to efficiency.
Gravity Feed vs. Siphon Feed
Best For: Small spot repairs, detail work, and short bursts.
Uses the top-mounted hopper. Media flows down naturally, requiring less air pressure to start. Ideal for high-precision jobs.
Best For: Large surface areas and continuous blasting.
Connects a hose to a large bucket of media. Allows you to work for hours without refilling. Perfect for big rust removal projects.
Step-by-Step Guide to Operating the AS118-2C
Sandblasting creates dust and debris. Always work in a well-ventilated area or a sandblasting booth. Must-haves: Goggles, heavy-duty gloves, and a respirator mask.
Attach the gun to your air hose using the 1/4" NPT fitting. Set your compressor regulator to 90 PSI for optimal results. (Range: 60-120 PSI).
For Gravity Feed: Fill the top hopper with dry abrasive (Sand, Soda, Aluminum Oxide).
For Siphon Feed: Insert the siphon tube into your bag or bucket of media.
Hold the gun at a 45-degree angle to the surface (not 90 degrees) to allow debris to deflect away. Move in smooth, sweeping strokes.
Ideal Applications
- 🚗 Automotive Restoration
- 🎨 Glass Etching
