An abrasive blasting enclosure without ventilation quickly becomes a dusty, hazardous haze, hindering productivity and safety.
Working in confined environments such as tanks calls for good ventilation. In some instances the coating that is being removed will contain hazardous substances (in the majority of cases this will be lead-based pigments). As these substances are considered toxic, specialised systems will be required. It is essential for the safety and productivity of the team of workers involved to maintain good conditions during the blasting process that allow them to keep blasting and complete the job faster.
There are certainly a lot of good reasons to keep the air moving through the tank.
By having good ventilation for your tank site you will:
All this means that you finish blasting sooner, you don’t contaminate the new surface, you send your workers in to clean up sooner, and consequently you can paint sooner. Time is money.
Sometimes it is very difficult to actually ventilate and control the overall air flow inside the tank effectively. Choosing the correct ventilation system is quite a consideration and must involve the type of waste contained in the dust and the requirements of the EPA, the local council and the customer.
There are a number of ventilation options readily available. Let’s start with the simplest one.
The Blast-One portable Blue Wizard Fans have the capability to blow clean air into a work space or extract dusty air from it with relative ease. Three high performance models are available from Blast-One and these fans have been specifically designed for this industry and can ventilate up to 10,000 cfm (283 cubic metres per min) - now that’s power! Easy and quick fan set-up using a 500mm (20”) flexible duct that connects directly to the fan from the contaminated area, the ease of operation is soon realised. Inflatable dust socks can be attached to the Blue Wizard Fan to collect visible dust particles (not suitable for hazardous dusts such as lead). The use of a dust sock is ideal for temporary containments and blast sheds. How do you want your fan powered? Blue Wizard Dust Extraction Fans can be compressed air powered, 3 phase electric (415V) or single phase electric (240V). Special electric units are available for use in hazardous areas containing combustible dust or flammable fumes.

Blast-One Mobile Dust Collectors are available from 6000 cfm to 60,000 cfm. They have been designed to be easily transported, easy to use and require very little maintenance. Units are powered by diesel engines or optional electric motor.
Dust laden air travels down the ductwork and enters into the dirty-air inlet plenum at the rear of the Dust Collector. Here the heavier particles drop out of the air stream. The air is then drawn through a large bank of specialised filter cartridges and dust is deposited on the outside of the filter cartridge. Filtered air passes through to the clean air plenum and is exhausted through the fan blower to atmosphere.
The cake of dust on the cartridges is dislodged continuously by a automatic reverse pulse jet. Dust drops into the hopper of the collector and is transferred by a screw conveyor to a conveniently located dust outlet for easy transfer to receptacle for disposal.
Do you have a tank or containment 100 metres away that you need to ventilate? No problem with a Blast-One Mobile Dust Collector, which incorporates a special high pressure fan that is designed to suck air along long lengths of ducting without significantly reducing air volume.
