Industrial air transport systems designed for demanding conditions. Flexible ventilation ducts that ensure safety and uninterrupted airflow in tunnels, mines, shipyards, production facilities, and underground infrastructure.
The largest Polish manufacturer of flexible ventilation ducts
We manufacture DLD flexible ventilation ducts from materials with enhanced thermal resistance, flame-retardant, fire-resistant, and antistatic properties (compliant with the ATEX Directive).
Our hoses have their origins in the mining industry, which means they offer the highest resistance to temperature, pressure, mechanical damage, tearing, and abrasion.
DLD ventilation ducts can be safely used in underground mining workings at risk of methane and/or coal dust explosions.
Our fabric ventilation ducts are used not only in the mining industry, but also in other sectors that require a constant flow of air.
Whenever installation time, low weight, and adaptability to specific environmental conditions are key factors, DLD flexible ducting outperforms traditional metal systems.
Lower ventilation costs
Up to 39% lower operating costs thanks to precise airflow direction and reduced pressure loss.
Quick assembly and disassembly
Textile ducts are much quicker to install - no heavy frames or specialized tools required.
Precise airflow control
Ventilation ducts made of fabric allow for very precise control of the airflow, ensuring that the air reaches exactly where it’s supposed to.
Acoustics and quiet working
Textile ventilation ducts are made of fabrics that naturally dampen vibrations and noise from the air handling unit.
DLD Ducts and Ventilation Systems
We offer a full range of ducts and accessories for building advanced ventilation systems.
We manufacture ventilation ducts with diameters up to 280 cm using automated processes. In addition, we are able to produce ducts with even larger cross-sections for specific projects.
As a manufacturer, we oversee the entire production process of ventilation ducts. Our products are made from high-quality coated fabrics (PVC, technical textiles)
Our ventilation ducts meet strict fire safety standards (VTM-0).
They do not produce sparks or accumulate static electricity, making them safe for use in potentially explosive atmospheres (ATEX-compliant).
Ideal for transporting warm air from heaters and for use in extreme temperatures (from -15°C to +80°C)
The fabric's tight weave prevents tearing, even at high operating pressures (up to 15,000 Pa).
Our products undergo regular testing at certified testing laboratories and are safe for use in underground mining operations where there is a risk of methane and/or coal dust explosions.
Our flexible ventilation ducts support leaders in key sectors of the economy. We provide solutions to customers in Poland and abroad.
Over
of experience in fresh air delivery
We have our roots in the mining industry, where mistakes are not tolerated. Thanks to this commitment to quality, we now supply air tunnels with the highest safety standards.
DLD ventilation ducts undergo periodic testing at certified testing facilities
The ventilation ducts we offer are subject to strict quality control. We regularly verify production standards, and each finished product is delivered to the customer with the appropriate documentation certifying its quality in accordance with applicable EU standards and regulations.
Do you need a custom diameter, a specific color, or printing on the channel, or do you simply want to customize the tunnel for your project?
