G+ Speed Air Duct

High-efficiency mine ventilation duct

 

CONVEY AIR FARTHER

The G+ SPEED AIR DUCT performance lies in its slick material and airtight couplings, which help convey air farther than flexible or steel tubing, even if assembled at angles up to 5° !

 

     
       50,000 cfm (23.6 m³/s) à 2297 ft (700 m)
     

Steel
   
       50,000 cfm (23.6 m³/s) à 984 ft (300 m)
     

Flexible 
   
       50,000 cfm (23.6 m³/s) à 781 ft (238 m)

 

MAXIMIZE UNDERGROUND SAFETY

The G+ SPEED AIR DUCT meets Canadian and American flammability standards for underground ventilation products. It is also highly visible, tear proof, and resistant to corrosion and impacts.

 


 

MINIMIZE ACCESSORY USAGE

The G+ SPEED AIR DUCT requires no elbow to follow drift curvature greater than 95 ft (29 m): a 5° turn calls for no accessories. It also adapts to any gallery configuration simply by swapping a round for an oval ring within a single tube length.

Consequence? 

Less leakage due to fewer duct couplings!

 

 

INCREASE DRIFT CLEARANCE

The G+ SPEED AIR DUCT conveys comparable airflow to steel or flexible tubing of larger diameter over equal distance.

Workers have better clearance to operate underground machinery.

 

 

SIMPLIFY VENT LINE INSTALLATION

Assembling the G+ SPEED AIR DUCT is a quick and easy process. A team can install between 5 and 10 ducts per hour !

   
Reform the duct in its round or oval shape after unpacking.
 
Insert and tighten the round or oval steel collars at each end of the duct.
 
Lift and insert the duct into position, then adjust to the drift curvature.

 


IMPROVE TRANSPORT & STORAGE LOGISTICS

The G+ SPEED AIR DUCT is both flexible and lightweight. It can be compressed, then inserted into crates to save room, handling, and inventory time.

The result ? Improved logistics and cost savings !

 

 

INCREASE ENERGY SAVINGS

By increasing both pressure and airflow in a vent line, the G+ SPEED AIR DUCT helps reducing the number of booster fans needed to ventilate drifts adequately. The ensuing lower fan power consumption leads to significant energy savings within months !

In the above scenario, a flow rate of 50,000 cfm (23.6 m³/ s) is required at a distance of 2297 ft (700 m). The vent line diameter is 48 in (1.22 m).

  • A G+ SPEED AIR DUCT vent line requires a single fan.
  • A similar line made of steel ducting provides as much air, but with 4 fans.
  • 8 fans are needed to achieve the same airflow in a flexible duct line.
