Best Sellers - Air Ventilator Hoses

Air ventilation hoses are designed with several different factors in mind. As such, these ducting hoses are very versatile products and have a huge number of potential uses. To boil it down to basics, the hose products are made to transfer air and facilitate circulation. But within that very broad definition, there is a huge number of applications that the hoses can be used for.

The Air Ventilator hose range is so versatile and effective because of the way the products are made. They are constructed from PVC rubber and vary in size from a 4-inch diameter to 24-inches, making them useful in every setting, from small-scale to industrial. The ducting is reinforced with a spring steel wiring that makes it extremely strong, even when flexed. It is also resistant to heat, standing up to a range of temperatures from -20 to 180 degrees Fahrenheit, while the Air Ventilator hoses can also compress to a fraction of their usual size. These hoses have a 10 to 1 compression ratio, meaning a 25 footer can compress to a 2.5ft size.

The range of applications for the Air Ventilator hoses are far-reaching. If there’s a need for air ventilation then this duct hose can fill it. That includes air conditioning, mobile and fixed chillers and dehumidification units. With the temperature resistance capabilities and the variety of sizes available, the hoses can be used in any setting, from an in-home HVAC system to large industrial machinery which needs ventilation tubing. While air flow – specifically in cold and heating systems – might be the primary use for the air ventilator hoses, they also have plenty of more obscure capabilities, such as a smoke ejector.

Ducting Insights -- Silicone: An Excellent High Temperature Material

Silicone is an important part of the rubber family, mainly due to the incredible qualities it possesses. While most materials wilt under extreme heat, silicone is special because it can stand up to extreme temperatures without seeing damage. It is this quality that makes it stand out among other materials and even other rubber types.

While the limits of silicone’s heat resistance are unlikely to be tested in everyday life, it is vital in some areas. For example, industrial machinery relies on silicone ducting hoses as a key component. Heavy machinery, such as those used in plastic and metalwork, reach extremely high temperatures, and need materials that can stand the heat. Silicone ducting can handle temperatures reaching 550 degrees Fahrenheit without degrading. A specific silicone ducting product will feature a number after its name, which indicates the top temperature it can withstand.

It is important to distinguish the difference between heat resistance and being fire-proof though. Silicone is one of the best materials there is when it comes to low thermal conductivity, which allows it to bear serious heat without damage. However, it could still sustain damage if it comes into contact with an open flame. This is because silicone’s temperature resistance and burn points are different. A flame can cause it to ignite, but heat leaves it unaffected – to the point of the duct’s heat resistance.

Different silicone products feature different aspects, such as insulation or fiberglass supports to increase the strength of the ducting. But it is the silicone itself that is best used to contain heat, making it an excellent high-temperature material.

Tips Before You Buy -- How a Duct Hose is Measured

The size of a piece of ducting will normally have to be very precise. To make sure you get the exact size you need, you should know the basics when it comes to measuring a duct hose. As long as you know how to measure the length and diameters of a duct hose, you should be good to go.

One of the most important aspects to be aware of is how the length of a duct hose is measured. Because a lot of ducting comes in flexible forms and can stretch considerably, this can cause some serious confusion. When it comes to the length, the measurement will refer to the hose at its most extended point – the absolute maximum length it can represent. In other words tow people pulling in each end of the hose should get it to its maximum or selling length. A compression ratio could also be recorded. This tells people what size the hose can be reduced down to. For instance, a ducting product with a 5:1 ratio would be 5 ft at its maximum length, compressing down to 1 ft at its smallest point.

Another key figure in the measurement of ducting is the diameter. This is the size of the circular opening at the end of the duct hose. If a straight line was drawn across that circle at its greatest point and measured, that number would be the diameter. It should not be confused with the circumference, which you would get by measuring around the circular opening. There are two separate diameters often recorded, labelled ID and OD – inner diameter and outer diameter. The ID measures from the inside edge of the ducting wall. The OD will be slightly larger, as it measures from the outer edge, taking into account the thickness of the ducting wall.
