300mm Black Rubber Air intake Ducting

300 mm is the largest bore stocked in this construction, used on main collection trunks, big fume extraction runs and plant air intakes where the volume is beyond anything a workshop system moves. It is black synthetic rubber over a wire helix with a corrugated outer wall, working from -10°C to 125°C, and it is rated for dust, chip, air intake and non combustible fume extraction only.

Key features

• 300 mm inside diameter, the largest bore stocked
• Black synthetic rubber, wire helix reinforced
• Corrugated wall so a duct this size can still be routed
• -10°C to 125°C
• Abrasion resistant and UV resistant
• DRFH300, cut 1 m to 9 m, or a 10 m coil

Applications

• Main collection trunks on large systems
• Cyclone and baghouse connections
• Bulk fume extraction on non combustible processes
• Plant and generator air intake
• High volume ventilation runs

Compatibility and fitting

• Ordered on the bore, so it fits a 300 mm spigot or duct end
• Band it with a heavy worm drive clamp from the clamp range, seated in a corrugation
• Support the run properly; a 300 mm duct full of chip is a serious load on a joint
• Rigid duct should carry the distance, with this hose taking movement and alignment

Is it a two-person job to fit?

Usually, yes. A 300 mm duct is stiff enough to fight back while you are getting it onto a spigot, and the clamp needs to be seated properly all the way round before it is tightened, which is easier with someone holding the duct square.

How much length should I allow?

Allow enough that the duct is not stretched between the two connections. A flexible spool pulled tight transmits every bit of machine vibration straight into the joints at each end.

Smaller bores, from 40 mm up, are in black rubber air intake ducting.
