Find answers to frequently asked questions that receives from customers.
Q: What is the Suction Excavator?

A: It's an equipment, mounted on a normal frame with 2, 3 or 4 axes, and it works like a "drum vacuum cleaner". It's endowed with one or more turbines generating an air stream of up to 44,000 m3/h and a maximum depression of 55,000 Pa. The sucking pipe has a 250 mm diameter.
Q: Up to what distance and depth can it suck?

A: The Suction Excavator allows to suck up to 150 ms in length and up to 30 ms in depth.
Q: How many cubic metres per hour does it suck?

A: In optimal situation, the machine can suck up to 30 cubic metres per hour.
Q: What kind of material can it suck?

A: The system and the power of sucking, can suck all types of material: solid, liquid and muddy. The effectiveness of filtering system allows the sucking of dusty materials reducing environmental impact.
Q: How does the Suction Excavator work? 

A: Operation principle is that of traditional drum vacuum cleaner. A 44,000 m3/h air flow with a maximum depression of 55,000 Pa, that carried in a 250 mm pipe, has the power to suck any type of muddy, liquid or solid material. 
Q: In which work can be used the Suction Excavator? 

A: The following are only some of the multiple uses of the Suction Excavator:
- Replacement of pipes and fittings
- Pipe bursts
- Renovation and new laying of gas-, water-, cable-, district heating and waste disposal pipelines
- Road scarification
- Railway trackside maintenance and repair
- When using ground displacement rockets
- Clearing away environmental damage
- Replacing contaminated soil around the roots of trees
- Renovation and demolition work
- Removing gravel from flat roofs
- Cleaning blocked street gutters and gullies
- Use in connection with horizontal boring units
- Vacuuming up foliage
- Underground construction work
- Replacement of contaminated soil 
Q: Which are the advantages in the use of the Suction Excavator? 

A: The Suction Excavator is faster and more efficient in excavation compared to traditional open cut methods, it increases the operational safety and reduces the excavation size and subsequent costs. The vacuum technology is approved in  contaminated ground and in the presence of existing infrastructure.
