Specialized flexible ducts reinforced with a steel spiral, designed for the efficient extraction of dusty air, harmful gases, and fumes in the most demanding mining, industrial, and infrastructure environments.
DLD flexible exhaust and forced ducts are advanced solutions designed for vacuum and exhaust systems. They are distinguished by their unique reinforced construction and exceptional durability.
The exhaust ducts manufactured by DLD undergo rigorous durability testing to ensure maximum safety and long-term performance in harsh environments characterized by contaminants and fluctuating pressures.
PVC-coated fabric and an integrated galvanized steel wire core prevent the cross-section from narrowing.
Guaranteed flexibility and stable performance at temperatures ranging from -15°C to +80°C.
Flame-retardant material (VTM-0 / self-extinguishing), ensuring high standards of fire protection.
They do not produce sparks or accumulate static electricity. They can be used in potentially explosive atmospheres (ATEX-compliant).
In environments filled with flammable coal or paint dust, the extracted contaminants generate static electricity on the walls of the ducts. Our exhaust air ducts are made of fabrics that dissipate these charges without generating sparks (anti-static), eliminating the risk of explosion (ATEX: Group I, Category M1/M2).
200-600
millimeters
Standard diameters, most commonly chosen for general industrial and building ventilation, as well as for hot-air transport.
800-2500
millimeters
Exhaust ducts with larger cross-sections for advanced systems and for ventilating work environments in mining and underground infrastructure.
1-10
meteres
Standard lengths for individual sections are 5 meters. As a manufacturer, we can produce custom sections of non-standard lengths, up to 10 meters.
Unusual
parameters
As a manufacturer, we also produce ducts with other, non-standard specifications.
What kind of duct do you need?
Effective dust control in mine faces, excavations, tunnels, and production halls.
They provide reliable, easy-to-move exhaust systems for welding, grinding, and sandblasting in the confined spaces of ship hulls.
Exhaust ducts are ideal for use as flexible arms and local exhaust systems in installations designed to remove dust-laden or chemically contaminated air from production facilities.
Thanks to their exceptional durability, DLD ducts can also be successfully used to convey granular materials such as grain, sawdust, or pellets.
