200mm Polyurethane Ducting Medium Grade

200 mm Polyurethane Ducting Medium Grade is clear polyurethane ducting with a copper coated steel helix. It is a large bore for collector connections and main trunks on abrasive dust systems.

Key features

• Nominal inside diameter 200 mm
• Wall material chosen for abrasion life rather than cost
• Anti-static copper coated steel helix, earthed at both ends of each section
• Transparent, which turns blockage hunting into a two minute job
• Light, flexible and weather resistant
• Temperature -5°C to +80°C

Applications

• Dust collector and cyclone inlets
• Main trunk runs
• Bulk material and grain transfer
• Sawmill and joinery extraction
• Industrial powder handling

Compatibility and fitting

• Sized on inside diameter: 200 mm ducting fits a 200 mm spigot
• Fix to spigots with a worm drive clamp behind the helix
• The helix must be bonded to earth to work as an anti-static duct
• Reserve polyurethane for abrasive duty; plain fume and air runs do not need it

Is the anti-static helix necessary at this size?

On fine combustible dust it is more important, not less, because the volume of material passing is greater. Bond the helix to earth at both ends of every section.

How is a run this size supported?

On saddles or straps at regular intervals, taking the weight off the connections. A large duct full of material is heavy, and hanging it off its spigots pulls the joints open.

Every size is listed in polyurethane ducting medium grade.
