Ducting Insights -- Duct Materials

We offer a wide range of flexible ducting materials and designs. Since we sell into a broad category of industries our hoses are made to transport air, dust, fumes or light materials in vastly different settings, from homes to industrial factories. While the design is important, the material used to create the hose can be even more so, dictating the capabilities of the product and allowing it to function in specific conditions.

Hoses can be made from materials ranging from light PVC plastic to rigid stainless steel, and each has its own merits. For instance, stainless steel ducts perform well in extreme temperatures, with some hoses even able to work in heats up to 1650 Fahrenheit. Ducts made out of stainless steel and aluminum are more rigid than others and are not made for continuous flexing. Instead, they can be bent into specific shapes and are then self-supporting. In contrast, PVC hoses are available and they are extremely flexible. PVC ducting can be easily flexed to fit different spaces and shapes. It is also available in a clear color, which is useful for applications where blockages might have to be identified.

PVC vinyl-coated polyester, urethane and thermoplastics are also used to form ducting hoses. The PVC coated polyester hose material is lightweight and offers a high degree of compressibility, while urethane has excellent abrasion resistance and a good level of general chemical resistance. Thermoplastics are often picked for applications where strong resistance is needed to moisture, UV rays, chemicals and abrasions. There are also FDA-approved hoses made of food grade materials which are certified as safe for contact with food. Across this wide range of ducting material options, just about every application and setting is covered.

4” Dust Collection Hose

When it comes to settings such as workshops and industrial processes, dust control is extremely important. Dust is created in a huge variety of ways, such as through cutting and sanding. For instance, CNC routers will produce a lot of dust, and when you are talking about a computer-operated industrial-scale operation, this can result in an especially large quantity of dust particles. These particles can be extremely harmful to a person’s health, as well as impacting the quality and precision of the work being carried out, making dust collection a vital consideration. Using a 4” dust collection ducting hose is a good way to clear the dust quickly and efficiently to keep the air clean.

A dust collection hose will often be made from materials such as thermoplastics or urethane. Opting for these materials gives your ducting more durable walls, which can be important when transporting a solid particle like dust. Sometimes larger chips can also be involved in dust collection, and the chosen hose has to be able to handle the abrasion caused by these materials. Both thermoplastics and urethane will offer more wall strength than a material like PVC. In addition, while most duct hoses are corrugated, when it comes to dust collection it is often best to go for a hose with a smooth interior. This is because smaller dust particles can become caught in hose grooves and corrugations, causing problems over time.

The size of a dust collection hose is also important. Many ducting options are available in a wide range of inner diameter sizes. But in the case of the smaller diameter, such as a 4” hose, you will get a greater suction power, yet the hose size is small and it is easier to handle. A 4” hose will provide high-quality routing and a greater efficiency of transferring dust and other particles through the duct hose.

Welding Fumes

Welding is a high-skill process that includes using extreme heat (which can come in various forms) to fuse two objects together. Unsurprisingly, it can be very dangerous if the proper precautions are not taken. One of the main dangers involved is the level of noxious fumes and gases which can be released while welding. These toxic fumes have to be properly ventilated, and that is where ducting comes in. Some low-level welding process may only require opening doors, windows and vents, or using general extractor fans. But when you are working in a high-danger environment, the proper welding duct hose should be used. This is the most efficient precaution and can remove fumes in high volume.

It is important to use the correct ducting equipment, especially when you are working with toxic materials and high temperatures. For the removal of welding fumes, which can be very hot, it is necessary to use a duct hose that can handle extreme heat. The most heat-resistant ducting materials are aluminum and stainless steel, but other materials such as silicone, neoprene, acrylic and even PVC can offer higher than average heat resistance.

Another important factor in choosing a ducting hose for welding is to know what kind of materials you will be dealing with. This is because different materials will give off different fumes, and different ducting materials carry different levels of chemical resistance. You might be dealing with simple smoke extraction, or it might be something more harmful or corrosive. It is vital to ensure that the hose can handle the process. For instance, PVC has good chemical resistance, but might not be suited for dealing with a certain chemical or noxious fume type. In that case, some more resistant such as stainless steel might be necessary. Community
