Spiral Ducting

Spiral Ducting has been developed to suit applications where extreme ruggedness and flexibility are required. The ducting has armour of continuous spring steel wire and reinforced profile which is solidly welded onto a heavy PVC coated fabric tube.

• Heavy duty woven Polyester/Nylon fabric both sides PVC coated.

• Spiral reinforced by spring steel wire.

• Seams and profile welded airtight.

• Low friction loss due to smooth inner surface.

• Suitable for high negative and positive pressure.

• Spring steel end rings.

• Galvanized suspension hooks.

• High wear resistance and tear strength.

• Flame resistance according to ASTM E-162 and EMR.

• Acid mine water resistant.

• Rugged construction.

• Ready for fast and easy installation.

• Antistatic feature optional.

• Adaptable to all fittings.

• Standard diameter 12" to 60".

• Standard length 25'. Also available in 10', 15' and 20'.

• Available in round, oval, rectangular and semicircle.

Fittings & Accessories

Spiral Flexible "Y", "T" and Fan Adapter are used for active development and stoping areas offering enhanced tensile and tear resistance.

• Heat welded and airtight construction with three heavy duty end rings.

• Spiral reinforced by spring steel wire.

• Very smooth inner surface – low friction loss.

• Flame and acid mine water resistant.

• Ready for fast and easy installation.

Flexible Fittings Rectangular & Half Round

• Designed for areas where space is at a premium.

• Manufactured in various sizes to match the same volume of air as round duct.

• Constructed from Heavy Duty PVC fabric, with reinforcing steel rods.

• Transition Sections – Rectangular and Half Round to Round Ducting.

• Tee Sections available in Rectangular, Half Round and Round.

• Various configurations available such as a 60"x30" Half Round Tee, 60"x30" Half Round to a 60"x30" Rectangular tee and a 60"x30" rectangular to transition 42" round.

Dispersion Ducting

The perforated window sections create a dispersing air flow for diluting gas and dust concentrations in haulage ways, cross cuts and other places where fresh air is required. Shape and position of the outletsections can be altered on request.

The volume of air dispersed can be adjusted by means of a Schauenburg Throttle Valve, installed at the end or in between the ducting columns.
