The Anti-Static Spot Blaster is a self contained, air powered, blasting device used in the aviation maintenance industry for corrosion removal. It will also remove welding blue, paint and etch composite materials. Ferrous debris is removed by a magnet in the unit's cyclonic separator to prevent media ( and hence surface) contamination. Static charges are conducted to earth by use of a special anti-static media hose and with bonding leads. The pistol head is sealed to the blasting surface by use of one of the eight flexible rubber nozzles. Used media and contaminate is drawn back by the air mover preventing leakage. The media is recycled and dirt is taken out to a paper filter (replaceable) contained in a fabric bag.

If air supplies are insufficient to run the unit correctly (27cfm @ 80psi) the air extractor can be isolated and the dust extraction effect provided by a separate, electric dust extractor.
Initial experience gained in rust control in the automotive field with a spot blaster system has led to Redashe’s development of this specially-adapted Anti-Static Spot Blaster to cope with aircraft corrosion. The equipment – an air-powered closed system device – is the result of close co-operation with the RAF.

This high-tech equipment offers several outstanding design features:

1. Light weight, compact and highly portable.
2. Positive seal on most surfaces; no leakage.
3. Media recycling system with ferrous separator.
4. Robust and simple to use.
5. Highly cost effective.

It can be used almost anywhere on an aircraft – even in the most inaccessible areas, such as inside wings. Precise blasting pressure control ensures that no panel damage occurs. Every trace of corrosion is removed safely and cleanly by the Spot Blaster. It can also be employed for small area paint stripping and to etch bonding surfaces on composite materials.

Unlike conventional methods, spot blasting exposes weaknesses in metal surfaces where corrosion may have penetrated deeply into the metal. The Redashe Anti-Static Spot Blaster uses a mixture of compressed air (from the standard workshop air supply) and blasting media, which is shot out of a long lasting tungsten carbide blasting nozzle onto the corroded part of the aircraft. A range of flexible rubber nozzles matches the surface contours to prevent dust leakage. An inbuilt air mover pulls back the used media, recycles it and any waste is taken out to a dust bag.

Its anti-static design features earths potentially-dangerous static through special hoses and bonding leads. This obviates the risk of explosion where inflammable solvents and fuel are present. All blasting media is recycled and cleaned within the unit. Ferrous particles are removed with a magnetic separator. Fine glass beads are employed for light surface corrosion and general polishing, aluminium oxide is used for heavier intergranular corrosion on aluminium or corrosion on ferrous fasteners. MoD and Nato approved, the Redashe Anti-Static Spot Blaster is already in airline service with such operators as Qantas, Air New Zealand and the RAAF locally and British Airways (including maintenance of the Concorde fleet) and British Midland. Units are also used in extensive aircraft and helicopter maintenance by the RAF and RNAS. Elsewhere, the Spot Blaster is employed by several leading vintage aircraft restoration companies, the Marine Builders Training Trust, and Formula One racing teams.

Applications for this specialist equipment also extend to offshore oil rigs for cleaning stainless steel welds.

The Redashe Anti-Static Spot Blast represents a highly cost-effective investment in defeating the curse of corrosion – and doing this essential task both simply and cost effectively.
