Warm air hoses

Flexible hot air hoses sewn by hand - on site in Germany.

Application examples: Building drying, ventilation, grain drying, hall and tent ventilation, stable ventilation, tank cleaning, hot air transport, winter construction heating.

All SPIRA hoses are optionally available with spiral-free end sleeves or end rings and suspension options. Endless connections are easily possible using end rings and quick couplings. Flat hoses without spirals are also available. For higher vacuum requirements, we can also manufacture the hoses with narrower spirals.

Advantages of our SPIRA hoses

1. Cost-effective and simple installation thanks to spiral-free sleeves and end rings.
2. Absolutely smooth inside, low flow resistance, no seam edges due to the longitudinal seam construction.
3. Medium does not come into contact with the spiral, therefore no risk of corrosion
4. SPIRA hoses are not glued, welded or clamped, but sewn. Extremely high tensile strength.
5. Extremely low heating of the outer spiral due to the additional insulation provided by the abrasion protection strip.
6. Available in all intermediate sizes up to a diameter of 1,000 mm.
