Ventilation Solutions for Mining Projects

We offer a comprehensive range of high-pressure ventilation systems for tunneling and mining operations.

Protan’s heavy-duty PVC-coated ducting can be highly customized and we can provide your project with straight ducts, adapters, reducer, Y and T pieces, bends and branches.

The result is a tight, lightweight system that is easy to install, repair and extend.

We provide very durable ducts with knitted polyester fabric which makes it extremely durable and strong for installations with extra high-pressure requirements. Protan ducts can be delivered with or without anti-static performance.

All Protan Ventiflex ducts have low internal friction which helps to reduce energy consumption, leading to a lower operational cost for the whole ventilation system.

Protan range of waterproofing solutions for tunnels and underground structures has been created and designed to meet the requirements of designers and installer respectively. Protan range of synthetic solutions, offers an excellent weldability, flexibility, mechanical strength, resistance to microorganisms and perforation by roots with an excellent service life to accomplish the most engineering projects.

Protan waterproofing membranes are manufactured in our factories and have UNI ENISO 9001 and 140001. The products fully comply with all relevant EU and D standards as well as having many other local accreditations.
