Vacuum blasters offer mess-free surface preparation

Nederman has launched its new 418A/460A and 418E/460E vacuum blasters. These air-powered, mobile, dustless abrasive-blasting systems are said to offer high suction power and separation efficiency.

Central to the design of the new Nederman dust-free blasting units is their mobility. Mounted on a steel frame with wheels, the 418/460 series can be manoeuvred anywhere around the workshop or factory. In contrast, the Preston-based company says that competitor models are often cumbersome, fixed floor-mounted systems.
The unit’s grit separator features a silo with an internal sieve, filling valve and vacuum producer. A pneumatic valve in the bottom of the silo empties the dust into a plastic bag. The efficiency of the system is highlighted by its ability to recirculate the shot media through the blasting and suction head (supplied as standard) more than three times. This reduces the cost of shot-blasting media, as well as downtime caused by time-consuming filling and cleaning operations.
Vacuum unit capacity is determined by the maximum blast pressure and the type of abrasive used. The sieve ensures that larger extracted particles cannot enter the blast vessel, while a compression pressure gauge informs the user of any change in operational pressure.
Nederman’s 193 kg 418 series offers 18-litre tank capacity. However, end users looking for more sustained blasting operations can consider the 460 series with its 60-litre capacity tank and 242 kg weight. The vacuum blasters can be supplied with a variety of hose lengths, nozzles and filters.
