General questions about technical hoses & their applications

How do I determine the correct inside diameter for my hose?

To determine the correct inner diameter for your suction hose, you must precisely measure the outer diameter of your connection element. The measurement result should ideally be slightly smaller than the inner diameter of the desired hose to ensure an efficient and safe connection.

Please note that our hoses are not expandable and precise sizing is critical. Use appropriate precision tools for sizing to achieve accurate measurement results.

What are the main differences between a PVC and a PU hose?

PVC (polyvinyl chloride) and PU (polyurethane) are two different types of synthetic polymers often used to make hoses. Here are some important differences between PVC and PU hoses:

Composition: PVC hoses are made of polyvinyl chloride, while PU hoses are made of polyurethane.

Durability: PU hoses are generally more durable and abrasion resistant than PVC hoses.

Chemical Resistance: PVC hoses are generally more resistant to chemicals than PU hoses

Temperature Resistance: Both PVC and PU hoses are resistant to high temperatures, but PU hoses can withstand higher temperatures for longer periods of time.

Cost: PVC hoses are generally less expensive than PU hoses.

What is the main difference between silicone and neoprene tubes?

Silicone and neoprene are two different types of synthetic rubber materials that are often used to make hoses. Below are some key differences between silicone and neoprene hoses:

Composition: Silicone hoses are made from silicone, while neoprene hoses are made from neoprene, a type of synthetic rubber.

Durability: Silicone hoses are generally more durable and wear resistant than neoprene hoses.

Chemical Resistance: Both silicone and neoprene hoses are resistant to a variety of chemicals, but silicone hoses have better overall chemical resistance.

Temperature Resistance: Both silicone and neoprene hoses are resistant to high temperatures, but silicone hoses can withstand higher temperatures for longer periods of time.

Cost: Silicone hoses are generally more expensive than neoprene hoses.

Are there plasticizers in the hoses?

No, there are no plasticizers in our tubes.

When should I change my hose?

As soon as your hose should show damages such as holes, cracks or similar, you should consider buying a new suction hose.

How should I store my hose?

For optimal storage, the suction hose should be stored in a cool, dry area away from direct sunlight and extreme temperatures (varies by application). Avoid sharp objects or surfaces that could damage the hose.

How long does a hose normally last?

The life of a suction hose can vary greatly and depends on many factors, including the type of media being passed, frequency of use, maintenance and specific operating conditions. Regular inspection for wear or damage can help maximize the life of your hose.

Questions about suction hoses & their applications

What are the main differences between a PVC and a PU hose?

PVC (polyvinyl chloride) and PU (polyurethane) are two different types of synthetic polymers often used to make hoses. Here are some important differences between PVC and PU hoses:

What wall thickness do I need?

This depends specifically on your application. In general, the higher the wall thickness, the smoother and more rigid it will be. Abrasive materials usually require a higher wall thickness.

How do I properly care for and maintain my suction hoses?

To prolong the life of your suction hoses, they should be checked regularly for damage such as cracks, holes or wear. If necessary, they should be replaced with new hoses.

What factors should be considered when selecting a suction hose?

There are several factors that should be considered when selecting a suction hose. These include the type of material to be extracted, the required suction power, the operating temperature, the chemical resistance and the flexibility of the hose. In addition, the size and length of the hose should also be considered.

What types of materials can be vacuumed?

Suction hoses are very versatile and can be used to extract a wide range of materials. These include dust, chips, gases, liquids and solids. The specific materials that can be extracted depend on the specific hose model and its characteristics.

How do I properly care for and maintain my woodworking hoses?

Proper care and maintenance of your woodworking hoses can extend their life and ensure their effectiveness. Clean the hoses regularly to prevent a buildup of dust and chips that could restrict airflow and reduce the efficiency of the extraction system. Also check the hoses regularly for signs of wear or damage and replace them as needed.

What factors should be considered when choosing a hose for woodworking?

When selecting a hose for woodworking, consider the size and shape of the hose, the type of material to be absorbed (fine dust or larger chips), the length of the hose, the flexibility needed, and the hose's resistance to abrasion. Some hoses are also anti-static, which can be important when working with wood dust to prevent the accumulation of static electricity.

How important is dust extraction in woodworking?

Dust extraction in woodworking is critical for several reasons. First, it contributes to workplace safety by reducing the amount of wood dust that becomes airborne and could be inhaled. Wood dust can cause health problems, including respiratory problems and allergic reactions. Second, effective dust collection helps keep work areas clean, which in turn improves the quality of manufactured products. Finally, reducing the amount of wood dust can help reduce the risk of fire or explosion, as wood dust can be combustible in high concentrations.

How do I properly care for and maintain my industrial vacuum hose?

Proper care and maintenance of your industrial vacuum hose can help extend its life and ensure optimum performance. Clean the hose regularly to prevent a buildup of dirt and debris that could affect suction performance. Also check the hose for signs of damage, such as cracks, cuts, or abrasion, and replace the hose as needed. Make sure the hose is properly connected to the vacuum and that all seals and connections are intact.

What size hose do I need for my industrial vacuum?

The required hose size for your industrial vacuum depends on several factors, including the size of the vacuum, the type and amount of material to be removed, and the specific requirements of your application. In general, larger industrial vacuums require larger hoses to provide adequate suction. It is important to follow the manufacturer's instructions or the advice of a professional to ensure you select the correct size.

Questions about hot air hoses & their applications

How does the construction heating?

Construction heaters are usually used to enable construction work during cold months or in cold climates. They provide a comfortable working temperature and prevent materials from freezing. Construction heaters typically use a heat source type, such as electricity, gas, or oil, to heat air. This heated air is then directed through special warm air hoses to the area to be heated.

How do I choose the right hose for my construction heating?

When selecting a hot air hose for construction heating, several factors should be considered. These include the operating temperature, the length and diameter of the hose, the material resistance (e.g. to temperature and/or other conditions) and the flexibility of the hose.

How do I install and maintain my construction heating hoses?

Installation of construction heating hoses should always be carried out according to the manufacturer's instructions. Typically, the hoses are connected to the heater and then positioned to effectively distribute the heated air. Hose maintenance includes regular inspection for damage or wear and thorough cleaning to remove debris and ensure efficient airflow.

Can I find a hot air hose for my application?

Yes, our hot air hoses are available in a variety of designs to cover a wide range of applications, from air conditioning and heating to use in particularly harsh conditions.

Can the warm air hoses be color matched to my needs?

Yes, we offer color matched warm air hoses that can perfectly match your event or project. Please contact us for more information.

Are the hot air hoses temperature resistant?

Yes, our hot air hoses are designed for different temperature ranges. Some models are even suitable for temperatures up to +150°C.
