Air Hooper Gun (FR-300)

Air Hopper Spray Gun-FR-300Industrial-Grade Tool for High-Volume Material ApplicationKey Specifications:Model: FR-300Type: HVLP Gravity Feed Hopper GunDesigned for spraying high-viscosity/large-volume materials.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).Nozzle Options: 4.0 mm, 6.0 mm, 8.0 mmSwappable 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).Hopper Capacity: 6000 ml (6 Liters)Massive volume for uninterrupted large-scale projects.Packaging: 6 pieces/carton (Optimized for bulk shipping).Design & Workflow AdvantagesHopper 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 ApplicationsConstruction/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.
