About Gaolijie — Industrial Duct Cleaning Equipment Manufacturer Since 2010

Gaolijie Industrial Equipment Co., Ltd. is a factory-direct manufacturer of professional duct cleaning robots and equipment. We design, engineer, and build every machine in our own manufacturing facility — no outsourcing, no rebranding, no middlemen. When you buy from Gaolijie, you buy directly from the factory that made your equipment.

We Are the Factory

Gaolijie owns and operates a dedicated manufacturing facility with in-house R&D, CNC machining, assembly lines, and quality control laboratory. Our engineering team includes mechanical, electrical, and software engineers who work together on every product — from initial concept through production testing to post-sale technical support.

Unlike trading companies that source from multiple factories and resell under their own brand, we control the entire manufacturing process. This means:

• Consistent quality — every machine is built to the same engineering specifications, not sourced from whichever factory offered the lowest quote that month
• Direct technical support — when you have a question about your equipment, you speak to the engineer who designed it, not a dealer who has to call someone else
• Genuine spare parts — replacement brushes, belts, filters, and electronic components ship directly from our parts inventory, not from a third-party warehouse
• Customization capability — need a specific voltage, cable length, brush type, or control configuration? We build it on our production line, not through a reseller's wish list

Manufacturing & Quality Control

Every Gaolijie robot undergoes a three-stage quality control process before shipment:

Stage 1: Incoming Material Inspection

Raw materials — stainless steel sheets, electronic components, motors, bearings, seals — are inspected against engineering specifications before entering production. Material certifications are archived for traceability.

Stage 2: In-Process Inspection

During assembly, each sub-system is tested independently. Drive motors are run under load. Cameras are calibrated and tested. Waterproof seals are pressure-tested on every unit. Control systems are verified across all channels.

Stage 3: Final Factory Acceptance Test

Before packaging, every complete machine runs a full functional test in a simulated duct environment. This includes drive performance, brush rotation, camera imaging, remote control range, and all safety interlocks. Test records are maintained for every serial number.

Engineering & Technical Support

Our engineering team provides ongoing technical support for the life of your equipment. This includes:

• Pre-sale consultation — our engineers help you select the right equipment for your specific duct types, diameters, and job profiles
• Video-call diagnostics — if you encounter a technical issue, schedule a live video call with our engineering team for real-time troubleshooting
• Spare parts within 48 hours — common wear items and spare parts ship from our factory inventory within two business days of confirmed order
• Operation training — every machine includes comprehensive documentation and video tutorials; we also provide live remote training sessions

Global Logistics & Export Documentation

Gaolijie ships to contractors, facility managers, and equipment dealers worldwide. Every machine is packed in a reinforced fumigated wooden crate with moisture protection for ocean and air freight. We provide complete export documentation:

• Commercial invoice and packing list
• Certificate of origin (Form E, Form F, or CO as required by destination country)
• Bill of lading or air waybill
• Product certificates and test reports
• Customs clearance support documentation

Why Factory-Direct Pricing Matters

The traditional equipment supply chain adds layers of cost between the manufacturer and the end user. Importer markup, distributor markup, and dealer markup can add 40-60% to the final price. By selling directly from our factory to your door, Gaolijie eliminates every layer of markup.

This isn't just about price — it's about value. The same budget that buys one dealer-sourced robot often buys a complete Gaolijie system: robot, HEPA vacuum, spare brushes, and accessories. For a contractor starting or expanding a duct cleaning business, that's the difference between partial capability and a complete, job-ready equipment package.

Our Commitment

Certifications & Compliance

Gaolijie products are designed and manufactured to meet international standards for safety, quality, and environmental compliance. Our equipment supports compliance with NFPA 96 (kitchen exhaust), NADCA (HVAC duct cleaning), VDI 6022 (European ventilation hygiene), and AS/NZS 3666 (Australian standards).

For specific certification documentation required by your local regulations or import authority, please contact our team — we provide full documentation packages with every shipment.
