The Air Ventilator Black is the ultimate flexible ducting solution for wide ranging air movement applications. This hose has an outstanding array of qualities and capabilities, setting it apart as a high-quality but affordable air movement product. Tough enough for industrial applications and affordable enough for residential use, the Air Ventilator also has a temperature tolerance of -20 to +180 degrees Fahrenheit. It can be used in anything from dehumidifier ducting to HVAC, portable air conditioning, smoke and hot air transportation, as well as all-purpose ventilation. This is a truly versatile duct hose for all settings and situations. These hoses are lightweight, constructed from a PVC-coated polyester fabric, making them exceptionally tough and durable. The body of the Air Ventilator is reinforced with a spring steel helix, which gives the duct work a higher degree of strength and helps it to keep its shape when flexed and put under pressure. Additionally, the hose has an external wear-strip. This rugged coating is added to protect the hose from excessive wear when it is dragged across the ground and ensure that it remains effective for the long term. Coming in standard lengths of 25 feet when fully stretched, Air Ventilator hoses are extremely flexible and have an incredible range of compressibility. A 25-foot hose can be retracted down to just 3 feet for tight-bending contortion when in use, not to mention easy transportation and storage the rest of the time. The Air Ventilator hose comes in a range of different colors, but this version is a solid black color for a sleek and subtle aesthetic. You can order this effective ducting hose in a wide range of diameter sizes, from a 4" inner diameter to a 24" inner diameter, to fit almost any opening type. Each end of the Air Ventilator is also fitted with belted cuffs, giving you a built-in quick and easy installation option without the need for clamps.
