Air Hooper Gun (FR-300)

Air Hopper Spray Gun-FR-300

Industrial-Grade Tool for High-Volume Material Application

Key Specifications:

1. Model: FR-300

2. Type: HVLP Gravity Feed Hopper Gun

   • Designed for spraying high-viscosity/large-volume materials.

3. Air Requirements:

   • Air Volume: 21 CFM (Requires industrial compressor ≥25 CFM).

   • Operating Pressure: 3.5 Bar (50 PSI).

   • Inlet: 1/4″ (Industrial BSP/NPT standard).

4. Nozzle Options: 4.0 mm, 6.0 mm, 8.0 mm

   • Swappable tips for varying viscosities:

     • 4.0 mm: Medium coatings (sealers, adhesives).

     • 6.0 mm: Thick materials (textured paints, heavy primers).

     • 8.0 mm: Extreme viscosity (mortar, fireproofing, plaster).

5. Hopper Capacity: 6000 ml (6 Liters)

   • Massive volume for uninterrupted large-scale projects.

6. Packaging: 6 pieces/carton (Optimized for bulk shipping).

Design & Workflow Advantages

• Hopper System: Bottom-mounted container for heavy materials; reduces strain vs. gravity cups.

• HVLP Efficiency: >60% transfer efficiency (minimal waste, EPA-compliant).

• Quick-Change Nozzles: Swap tips without tools for job flexibility.

• Industrial Build: Heavy-duty aluminum/steel construction.

Typical Applications

• Construction/Industrial:

  • Spraying fireproofing coatings 🔥

  • Applying cementitious textures 🏗️

  • Roof sealants, epoxy coatings, soundproofing materials.

• Automotive/Manufacturing:

  • Underbody coatings, truck bed liners 🚛

  • High-build primers.

Critical Requirements & Warnings

⚠️ Compressor Must Exceed 21 CFM (e.g., 25-30 CFM industrial models).
⚠️ Material Prep:

• Strain all materials to prevent nozzle clogs.

• Maintain viscosity ≤100 sec (DIN4 cup) for 8.0 mm tip.
  ⚠️ Clean Immediately: Residue hardens rapidly in large nozzles.
