Nederman introduces new vacuum blasting technology

15 February, 2017

Nederman has launched its new 418A/460A and 418E/460E vacuum blaster, an air-powered mobile dustless abrasive blasting system that is claimed to offer superior productivity, suction power and separation efficiency.

Core to the design of the Nederman dust free blasting unit is its mobility. Mounted on a sturdy steel frame with wheels, the unit can be manoeuvred anywhere around a workshop or factory. Additionally, the new development from Nederman can be supplied with a variety of hose lengths, nozzles and filters.

Nederman has developed the 418/460 Series as a complete mobile system. It is mounted on a trolley with a grit separator and it has a silo with an internal sieve, filling valve and efficient vacuum producer.

A pneumatic valve in the bottom of the silo empties the dust into a plastic bag. The efficiency of this system is highlighted in its ability to re-circulate the shot media through the blasting and suction head beyond three times. This is said to significantly reduce the cost of shot blasting media, as well as reducing downtime with time consuming filling and cleaning operations drastically reduced.

The pressure blasting system also comes with a 10m hose and a blasting and suction head as standard. The capacity of the vacuum unit is determined by the maximum blast pressure and the type of blasting abrasive used. The sieve ensures that larger extracted particles cannot enter into the blast vessel. The filling cone is pushed up by the blasting abrasive and the lid above it ensures sufficient clearance to eject the abrasive.

The robust steel constructed 418/460 Series has a blasting capacity that depends upon the chosen application. With high working pressure and maximum airflow, the 418/460 Series has a compression pressure gauge that rapidly informs the user of any change in operational pressure.

The 193kg 418 Series has an 18-litre tank capacity. However, end users looking for a larger tank capacity for more sustained blasting operations can consider the new 460 Series with its 60-litre capacity tank and 242kg weight.
