• The ventilation duct is mainly made of canvas material and lined with steel wire keel support, which has the characteristics of heat insulation, flame retardant, waterproof, and oil-proof.
• The smoke exhaust pipe is made of thick conformal fabric, waterproof, fireproof and heat-resistant, igniting the flame, and the flame will automatically extinguish in 3-6 seconds, and can be wiped with water or a damp cloth.
• Ventilation duct hose is used for exhaust, smoke exhaust, exhaust, fan, kitchen smoke exhaust, environmental protection equipment dust removal, mechanical equipment ventilation duct, air conditioning exhaust.
• 180° arbitrary bending, no rigid bending, integrated molding, elongation compression without flanging, layering, deformation, with certain radial compression and expansion performance.
• The exhaust pipe can be easily folded and unfolded, folding for easy storage and transportation, and the flexible air duct design increases the applicability of intake and exhaust scenarios.
