PRODUCTS PROVIDED

Flexible Ventilation Ducting

The construction of our venti-ducts includes specialized PVC-coated polyester fabric, wire ropes for section coupling, metal coupling clamps for better coupling and locking suspension hooks. In particular the fabric of the venti-ducts offers exceptional tear and tensile strengths. It doesn’t tear even if it is exposed to the highest air pressures of the ventilator or any cause of damage. It also has surface resistant characteristics, and as for its flame resistance, it meets fire and toxicity criteria.

Coupling System
Zip Coupling - Steel Ring Connection with Multi-Clip Metal Clamps - Steel Ring Connection with Over-Cover Metal Ring

Suspension System
MatHellas flexible ducting is delivered with double locking suspension hooks made from hot-galvanized steel. The distance between them will be 50cm. The hooks are fixed to the ducting by fabric reinforcements fully welded along the whole venti-duct and they are clipped on a suspension messenger steel wire in the mine ceiling.

Special Items
A wide range of Y and T-branches, bends and cones can be designed and manufactured as required. They are manufactured in the highest quality fabric and all the pieces guarantee a proper aerodynamic design with reduced pressure loss.

Repair Kit
Includes pieces of PVC750 fabric (same as the Ventilation Ducting fabric), LEISTER handheld hot air welder, silicone roller, three Zipper Repair Sleeves.

All tears or holes in the ducting fabric caused by accidental damage must be repaired as soon as possible. Tears or holes in the fabric can easily be repaired by welding a patch on with a hot-air hand welder machine (type Leister). For the welding, one press roller is also necessary.
