• Custom Length Orders Welcome
• Ability to manufacture ducting to suit your needs.
• Connections available: Multi Clips; Coupling Bands; and Integral Flexible Quick Release Couplings.
• Increased clearance at the back or pillar for travelways.
• Increased air volume by maximizing available space for duct.
• Reduced drift size to accommodate ventilation and equipment.
• Reduced waste tonnage for new development drifting.
• Variety of size combinations, lengths and designs.
• All ducting and fittings available in both Lay Flat and Spiral reinforced.
"Quick Connect" - Features and Advantages
The "Quick Connect" system is available on all Flexible Lay Flat and Spiral ventilation products.
• Joining lengths take 75% less time than the conventional multi clip system.
• All hardware is attached to the duct.
• There is no bunching at the joints, improving air flow resistance, resulting in fan energy savings and allowing the miner to connect quickly and correctly, thus eliminating leakage.
• Miners can quickly suspend and remove ventilation ducting using the "Quick Connect" clips.
• "Quick Connect" clips are installed off messenger cables for faster and more efficient installation.

Multi Clips
Used for large diameter ducting where ease of installation is essential. Unit consists of a flat base plate with pressed in 5/16 carriage bolt; preformed top plate to fit over the end rings of ducting; and a 5/16 wing nut to hold assembly and end rings of ducting together.
Coupling Bands
A full circle of yellow PVC extrusion profile and a patented locking clip profile is placed over both end rings of the ventilation ducting and by tightening the steel wire within the profile an airtight joint is produced.
Integral Flexible Quick Release Couplings
The Integral Flexible Quick Release Coupling can be incorporated into our complete line of flexible PVC ventilation ducting enabling you to join two lengths of ducting in seconds. Each length of integral coupling ducting comes complete with one end fitted to the PVC coupling and quick release toggle clamp and a standard flexible end ring on the other end. Simply place the end ring inside the coupling and with one motion of the handle, the two lengths of ducting have an airtight joint.
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.
