Layflat Blower Ducting


TruOval MineVent®, is a patented*, oval layflat blower ducting engineered to increase air distribution efficiency throughout your underground ventilation system.


The unique construction features suspension cables spaced intermittently through the ducting to maintain its oval shape while reducing the amount of air flow friction. The oval configuration maximizes headroom in confined spaces and allows larger equipment to travel through the shaft without disrupting air flow. 


TruOval MineVent® ventilation ducting also features a series of easy-to-handle accessories that require less space, are 
more cost-effective, and smoothly transfer air through bendsand turns.


TruOval MineVent’s® welded construction reduces air loss and weakening associated with conventional sewn ducting. The durable RipStop substrate prevents small tears from expanding to major holes. Molecularly bonded for positive pressure applications, TruOval MineVent® is manufactured with VentaTex® material, which is designed to perform from -20° F to 180° F (-29° to 82° C) continuously. MineVent® fabrics have been tested and approved by Mine Safety and Health Administration Standards (MSHA).
