🔄【Ideal Ducting】This is a 4-inch diameter vent hose. You can adjust the length from 1.3 to 25 feet for any general purpose HVAC application.
🔄【4-Layer Structure】Our vent hose is constructed of dual-layer flame-resistant aluminum foil and dual-layer PVC thermoplastic. With protection, this duct hose is extremely durable and not easily torn compared to a single-layer design.

🔄【Easy to Use】Installation is easy by attaching each end to the opening of the appliance. The included stainless steel clamps help secure the hose from leakage. You can bend or cut the tube freely to fit your unique space restrictions.
🔄【Multiple Applications】This ducting is primarily used with duct fan systems for air circulation in hydroponic grow tents, smell and moisture removal in bathrooms, and hot air exhaust in computer rooms. This ducting can also be used to remove smoke and odors during industrial laser cutting processes.
