Key Features:
- Made in the USA: Manufactured with quality and precision.

- Maximum Pressure: Supports a maximum working pressure of 150 pounds per square inch (PSI).
- Air Inlet: Equipped with a 1/4" NPT air inlet for standard connections.
2. Setup
- Connect Air Supply: Attach a standard 1/4" NPT air hose from your air compressor to the air inlet of the siphon spray gun. Ensure a secure connection to prevent air leaks.
- Prepare Liquid Source: Insert the siphon tube into the liquid you intend to spray (e.g., degreaser, cleaning solution, lubricant). Ensure the tube reaches the bottom of the container for continuous flow.
- Check Pressure: Verify that your air compressor is set to a pressure suitable for the task, not exceeding the maximum recommended pressure of 150 PSI. The gun operates efficiently at 100 PSI for 14 SCFM.

3. Operating Instructions
- Activate Air Flow: Press the trigger on the blow gun to initiate air flow.
- Begin Spraying: As air flows, it creates a vacuum that siphons the liquid from the container through the tube and sprays it out with the compressed air.
- Adjust Distance: Vary the distance between the gun nozzle and the target surface to control the spray pattern and intensity. Closer distances provide a more concentrated spray, while further distances offer wider coverage.
- Applications:
- Degreasing: Use with appropriate degreasing solutions for engines, garage bays, and mechanical parts.
- Spraying: Apply water or other suitable liquids to plants and flowers.
- Rust-Proofing/Lubricating: Apply rust-proofing agents or lubricants to tools and machinery parts.
- Cease Operation: Release the trigger to stop the air and liquid flow.
4. Maintenance
- Clean After Use: After each use, especially when spraying corrosive or viscous liquids, run clean water through the siphon gun to flush out any residue. This prevents clogging and extends the life of the tool.
- Inspect Siphon Tube: Regularly check the siphon tube for kinks, blockages, or damage. Replace if necessary to ensure proper liquid flow.
- Store Properly: Store the blow gun in a clean, dry environment away from extreme temperatures and direct sunlight.
