Standard Galvanised Mine Ventilation Ducting


Manufactured from 1.0 mm; 1.2 mm and 1.6 mm Z275 galvanised steel. • Diameters: 305 Ø; 380 Ø; 405 Ø; 570 Ø; 760 Ø; 915 Ø; 1015 Ø; 1220 Ø & 1500 Ø. • Ducting lengths manufactured to customer specifications and requirements. • All flanges manufactured from rolled angle iron.

Enerduct ®

The Enerduct is a new concept of duct design and manufacturing. CFD Simulation and Analysis of Air Flow on the newly spiral-swage formed ventilation duct were conducted by the CSIR to determine the flow characteristics in the Enerduct pipe. Results from the Simulation and Analysis research proved that the design of the spiral swage reduces the frictional pressure drop by between 8.80% and 13.04% at different volumetric flow rates.

South African Registered Design F2014/00686

South African Patent ZA2015/01483

Rectangular Ducting and Fittings

Rectangular ducting for Underground and Industrial applications. Manufactured from Z275 galvanised material in lock-form construction with angle iron flanges as joining method.

Underground Applications: Ducting can be designed for areas with limited space available where conventional round ducting cannot be installed. Flanges can be supplied with clamp-hooks on top of flange which do not require bolts and nuts due to limited space during installation.

Industrial Applications: Sub-station ventilation systems and plant ventilation systems.

Standard Sizes: 405 Ø (650 x 200); 570 Ø (1020 x 250); 760 Ø (1300 x 350); 915 Ø (1650 x 400); 1015 Ø (1620 x 500); 1220 Ø (1950 x 600). Alternative sizes can be manufactured on request and as per client specification.
