Flexible aeration hoses: Safe and efficient suction
Flexible polyurethane aeration hoses are an ideal solution for industry.
These hoses are made from a transparent polyurethane compound reinforced with a copper-plated steel spiral , offering a perfect combination of strength and flexibility. Their design makes them especially suitable for use in extraction arms and vacuum equipment, as their robust construction allows them to efficiently transport shavings, air, dust, and other materials. In addition to being extremely abrasion-resistant, these hoses are antistatic, preventing the buildup of electrical charges and ensuring a safer and more efficient work environment.
The materials are broken down below for a better understanding of the success of this hose:
Polyurethane (PU)
Polyurethane is known for its exceptional abrasion resistance, much greater than that of PVC and rubber, as it retains its properties even at extreme temperatures (it withstands temperatures from -40ºC to +100ºC).
This makes it ideal for transporting highly abrasive materials such as wood dust, shavings, granules, or cement. Furthermore, polyurethane is lightweight, flexible, and resistant to oils, greases, and hydrocarbons.
Copper-plated steel spiral
On one hand, the spiral allows the hose to maintain its shape and not collapse under strong suction, ensuring a constant and uninterrupted flow. On the other hand, the copper coating acts as an electrical conductor, dissipating the static charge generated when transporting powdered materials.
The Disumtec range
We have 3 different models available, depending on the thickness that best suits the installation:
- Standard thickness (lightweight) . Ideal for extraction applications handling air, fumes, or light, non-abrasive particles. It's the most flexible and economical option for applications where weight and ease of movement are priorities.
- Medium thickness. This option offers a balance between flexibility and strength. It is commonly used for vacuuming wood chips, plastic, and other granular materials with moderate abrasion.
- Heavy-duty thickness (maximum abrasion resistance). Designed for the most demanding and abrasive jobs, it offers superior resistance to abrasion and crushing. Essential for transporting heavy materials such as rubble, sand, gravel, or wood chips.
Keys to installation
- Choose the right length. You must accurately measure the distance between the connection points. A hose that is too short will be under constant strain, while a hose that is too long may collapse or become tangled.
- Use the correct clamp. The clamp should hold the hose securely without deforming it. Always use a worm gear or band clamp designed for this type of hose, and in high-vibration applications, consider using double clamps for added security.
- Respect the bend radius. Although they are very flexible, each hose has a minimum bend radius specified by the manufacturer. Forcing too tight an angle creates excessive stress on the hose wall and coil, which can lead to cracks or splits.
Industrial applications
Thanks to their reinforced design, polyurethane hoses are the preferred choice in a variety of industries:
- Woodworking industry. They fit perfectly on extraction arms and suction systems that handle dust, shavings and chips.
- Agricultural sector. They are ideal for transporting grains, cereals and fertilizers, where abrasion is a constant factor.
- Chemical and plastics industry. They are used for the transfer of plastic granules or chemical powders that require a resistant and anti-static hose.
- Ventilation systems. They are useful for the extraction of fumes and gases in environments where lightness and flexibility are necessary.
Available qualities
- For the food and beverage industry:
Hoses designed for the food industry are made from a food-grade polyurethane compound that complies with FDA regulations. They are also non-toxic, tasteless, odorless, and have non-porous surfaces.
These types are essential for the transport of sugars, flours, grains, dairy products, and cosmetics.
- For ATEX environments:
Hoses for ATEX (Explosive Atmospheres) environments incorporate a steel spiral that must be grounded. The spiral acts as a conductor, safely dissipating static charge and preventing sparks.
As you can see, choosing the right polyurethane suction hose goes far beyond size. If you have questions about how to install a specific hose or need help selecting the right one for your application, please don't hesitate to contact us.
