Industry: Catering Equipment Manufacturing/Environmental Protection Equipment
Country: United States
Pain Points:
The customer needs to install a primary filter on the top of the barbecue stove chimney, but faces two major challenges:
High temperature risk: coal burning oil fume contains sparks, and conventional filter materials are flammable;
Installation restrictions: The chimney cannot be welded and fixed, and the customer refuses to modify the chimney structure.

Core materials:
▶ Use F9 grade flame retardant filter paper (temperature resistance>150℃) to intercept oil fume particles while eliminating the risk of spark ignition;
Innovative structure:
▶ Customized adjustable air filter cartridge, suitable for chimneys of different diameters;
▶ Directly lock the outer wall of the chimney with a stainless steel clamp, without welding or threaded interface, and install quickly in 5 seconds.
✅ Successfully achieve stable installation on the top of the chimney, with zero modification cost for customers;
✅ Flame retardant filter paper + closed structure eliminates fire hazards and complies with US safety regulations;
✅ Primary filtration efficiency significantly reduces particulate matter emissions and meets environmental protection requirements.

🔥 Safety first: a protection solution designed specifically for open flame scenarios;
🔧 Ready-to-use: solves the installation problem of scenarios without fixed interfaces;
🌫️ Efficient and compliant: achieves the initial particulate matter filtration goal at a low cost.
