Ducting hoses and ventilation hoses – general information

Ducting and ventilation hoses are very lightweight and flexible. They are designed to extract and convey gases and fumes of different substances, dust, sawdust, wood shavings, wood chips, loose bulk materials and granules, also highly abrasive. Available in a wide range of sizes, including diameters bigger than 300 mm. Ducting hoses are extensively used for suction (under vacuum) but also as delivery hoses (under pressure) to blow air or gases.

The ducting hoses are made of thermoplastic material (e.g. polyurethane) or fabric coated with some pastic material (e.g. silicone-coated polyester). The resistance to vacuum is ensured by steel wire helix, steel strip helix or plastic helix. This vacuum resistance depends mainly on helix thickness, whereas abrasion resistance depends on hose wall thickness and the material it is made of.

Ducting and ventilation hoses can be divided into the following groups:

The ducting hoses are connected to a pipeline using clips and clamps, with the use of connectors and reductions (described in connectors for ducting hoses)

FAQ – ducting hoses:

What are the basic parameters of a ducting hose?2023-07-03T15:31:25+02:00

The basic parameters of a ducting hose are: inner diameter, wall thickness, working pressure, bend radius, working temperature, antistatic properties, fire resistance, resistance to microbes and hydrolysis.

What properties should a hose for abrasive bulk media have?2023-07-03T15:33:14+02:00

A ducting hose for abrasive, loose bulk media such as plastic granulate, sand, sugar, gravel or quartz should have good abrasion resistance – solid particles rubbing and hitting against the hose walls make it wear out. Therefore, ducting hoses with a sufficient wall thickness (thick-walled) > 1.0 mm are most suitable. It is also very important to prevent the occurrence of static electricity, i.e. to use materials with static dissipative properties (conductive material: R ≤ 10^6 Ω ; 10^6 Ω < R ≤ 10^9 Ω) and combat accumulation of charges in the hose. It is important that, when using a hose with an antistatic wire, it is permanently and effectively attached to the fittings and grounded, although this wire will not completely replace the antistatic/conductive inner layer.

What is the correct way to install a ducting hose?2023-07-03T15:34:16+02:00

Polyurethane ducting hoses are installed with right-hand bridge clamps and CLIP fabric hoses with left-hand bridge clamps. The clamps are available in the range from 25 mm to 915 mm and in W1,W2,W4 and W5 material version. We also offer steel connectors in various configurations (straight, elbows, reducers, tees, etc.) for the extension of a ducting system.
