technical solutions as well for media-transport as for additional cover incl. our protector™ familiy.


In case of bending the hose without any pressure a variation of the cross section has to be considered. While bending in pressureless condition a cross-sectionchange of 10% has to be considered.

The bending radius is reduced by approx. 50% at a pressure of 1 bar. This pressure prevents the hose from kinking.

good chemical resistance


While bending in pressureless condition a cross-sectionchange of >= 10%   has to be considered.

The bending-radius reduces to the appr. half at an inner pressure of 1 bar, because the pressure counteracts the snapping.

Ventilating- / Suction-Hoses

A high tensile connection between hose material and external helix results to special clamping proceeding.


We produce our hoses without using manufacturing processes of sticking, vulcanising, welding or seeming.

Adhesive free and seamless construction means:
Durability also at highest temperature because of no possible melting of any glue. The continues connection of the hose material guaranties a much higher tensile strength and more closure connection compared to seemed ones.

Outer helix means:
Media does not contact the material helix, therefore no corrosion.
-inner hose wall smooth therefore less flow resistance
-additional protection for external hose sheat
-crush resistant

Helix construction means:
-highly flexible
-small bend radius
-extremely compressibility
-coast effective storage

Continues length production means:
-deliverable as coils
-cost effective installation
-no need for spiral free muffles at the end because hose can be assembled with special hose clamps
-easy to assemble

How to cut:
Using sharp knife, cut the hose material through to reinforce spiral and cut it then with a side cutter.

The use of high quality material eliminates a possible rove of the cloth.

Assembly instructions:
Assembly instructions from producers side are to be respected.
Wrong assembling reduces the life time of the hoses and inapplicable claims under guaranty. Arrange flexible hose line as freely suspended bends in such a manner that they do not come in contact with the wall or other objects or with the ground even during extended stroke. Install flexible hose line at 180° with sufficiently neutral hose ends. Decide on installation interval in accordance with the required band radius. Use rigid pipe bands to avoid impermissible bends directly behind the connection fittings.
Observe the minimum band radius. Movement direction and hose access must be level. This prevents harmful torsional strain occurring. Low lethal movement is permissible.

Material abbreviations:

CR = Neopren
CSM = Hypalon
EPDM = Ethylen-Propylen-Dien-Kautschuk
FPM = Fluor-Kautschuk (Viton)
NBR = Perbunan
PA = Polyamid
PE = Polyäthylen
PP = Polypropylen
PTFE = Polytetrafluorethylen (Teflon)
PUR = Polyurethan
PVC = Polyvinylchlorid
VMQ = Silicon-Kautschuk

All specifications are the result of internal tests and trials on internationally recommended standards and refer to a medium and ambient temperature of +20°C. Deviating temperatures can alter the pressure and theckum specifications. Due to the construction the length of individual hose types maybe affected by the influencing variables of pressure, vacuum, medium and ambient temperature. This alteration in length must be taken into account by the user during operation. Although this hose type is build for extraction by suction, conveying and blowing of gaseous media and airsupporting particles, they can also be use for transport of splinters and other products.
