Portablast Enclosure

Enclosed work area

The Porta-Blast system is supplied with a purpose made 610gsm PVC material cover that encloses the blasting and painting work area.

The cover material is fire resistant and will not aid in the spread of fire, should one occur.

The cover is also translucent white to allow as much natural light as possible come into the blasting and painting area. The reason for this is two fold.

Firstly it means artificial lighting is not required, unless you are blasting and painting at night time. During daylight hours, sufficient light will flood the work area so as to not require additional electrical lighting. If lighting is required for night work we have a range of explosion proof LED lights available.

Secondly, natural light is a much better light under which to inspect surface finishes and paint colours. What you see is reality, and not distorted by artificial lighting. Strangely, the same paint viewed under artificial light and in daylight can look a very different colour.

Large access door

The standard rear wall of the enclosure is supplied blank. If required, a man or workpiece access door can be fitted here. The front wall is the workpiece entry and exit point and is fitted with a manual lift up access door. This door will provide adequate access to the work area. The manual lift up door is very light and simple to operate. Sealing tightly at the sides prevents any dust escaping.

Enclosure life

You maybe thinking that having a blastroom built from PVC material is going to wear out very easily. Well in a way you are correct. Eventually it will wear out. This structure is not a permanent blastroom build from 6mm steel plate with a 6mm rubber lining, that is going to last a lifetime.

But it will not wear out as quick as you would expect, for the following reasons.

Firstly the enclosure is loosely tensioned. This means when it is impacted with abrasive particles it absorbs the energy of the impact. Secondly, most of the abrasive that hits the enclosure material is abrasive that is rebounding from the work piece and has therefore lost most of its kinetic energy. By the time the abrasive gets to hit the walls or ceiling all its speed has already been lost so it will do little damage.

Cheap to replace

But it is inevitable there will eventually be damage to the canopy material. When this occurs the cheapest and quickest solution is to patch up any holes. If you are practically inclined enough to be involved in blasting and painting, you are certainly handy enough to patch a few holes in a canvas. If the canopy has been damaged beyond repair, it is actually surprisingly cheap to replace the whole thing. The complete replacement canopy material for the 2020 model costs from USD1060 only. And this will be a drop in the ocean compared to how much grit and disposal costs will have been saved.
