Material handling hoses can build up large amounts of friction that result in build-up of static electricity. When materials are moved through a flex duct, built-up static electric charges will occur on the individual grains of wheat dust or wood ships being moved. This occurs because the dust particles are constantly moving and colliding with each other. When this happens a bit of electric charge is transferred from one particle to another. If the process goes on long enough, you can have many kilovolts difference across the grain container. This is enough to cause a static discharge just like lightning and if the dust is flammable (e.g., wood dust or grains) then a very powerful explosion can follow. This is the exact scenario which anti-static hoses have been designed to protect against.
Because of the risks that static electricity presents, it is important to utilize anti-static hoses to ensure that your hose maintains maximum airflow and reduces the risk of fire damage. At Ducting.com we offer conductive hose designed to effectively transport materials and prevent static build-up. Our static dissipative hose features specially made duct materials that allow the hoses to transfer large amounts of material without building up static. This is ideal for applications like woodworking where the conductive hose prevents the static build up from collecting wood dust and creating a spark that could set fire to the flammable dry wood materials. The anti-static hoses work to prevent the build up when the ducting is firmly grounded and attached to the ventilation device.
Along with the ability to prevent static build-up, our static dissipative hose is also extremely durable. Our conductive flex duct products are made of either polyurethane or double-ply neoprene to provide excellent resistance to outside abrasions. The anti-friction properties of neoprene and polyurethane provide a tough surface, minimizing the potential static buildup in the flex duct greatly, while being surable. Compare this to metal conductive hose such as aluminum or stainless steels, materials which are more prone to generating static accumulation. The durable materials used for these anti-static hoses also provide them with superior chemical resistance. The durability and resistance to abrasive chemicals and materials make this flexible ductwork a great long-term investment.
Because grounding is essential in utilizing the anti-static features of this product, it is also important that a hose be flexible. Our static dissipative hose have the flexibility you need to keep the flex duct grounded and reach the materials necessary without sacrificing their air-flow or creating static build up. The versatility of these duct materials make them a great choice for a wide range of applications where static build up would occur when picking up materials like wood chips and dusts. Aluminum shavings –small bits of loose metal – can be especially problematic, especially when using aluminum, stainless steel, or other metal duct materials.
Our online catalog of anti-static hoses features detailed descriptions of the ducting materials for your convenience. Order online today or call one of our ducting specialists to assist you with your order. It might not be readily apparent to you, the consumer, at first which type of conductive hose best suits your static dissipative hose needs. For that reasons, we recommend getting in contact with our staff when it comes to answering your flex duct questions!
