Part 1: The Blasting Enclosure

Before deciding on a blast room, it’s best to familiarize yourself with among the features frequent across most manufacturers. Nearly all blast rooms characteristic a sq. roof design instead of hip-type roofs. The square roof construction allows for more operator movement, easier load-in and load-out, and has better lighting. Light gauge hip roof models – which are sometimes the cheapest on the market – might not provide the durability and usability you are looking for.

Wall and roof panels are usually available in thicknesses that range from 18 to 10 gauge or thicker. As a general rule, the heavier the wall thickness, the higher the cost.

Get The Proper Dimension

Make positive the blast room is the best size. Many of the considerations we outlined in our powder coating oven size guide will probably be applicable here, however make certain you give your components and your operator loads of room. For instance, if the elements you want to blast are very tall, consider adding some additional height to the cabin so you won’t continually be blasting into your light fixtures or the unprotected ceiling surface. Also, if the part you want to blast takes up the keyity of the cabin, give your operator extra width and size to safely work across the part without standing in a stream of blasting media bouncing back towards him.

Part 2: Blast Pot

The blast pot (also referred to as a blasting pot, pressure pot, pressure vessel, media blaster or portable blaster) is the appliance that does the actual blasting. There are a number of blast pots on the market, however all of them work essentially the identical way. A blast pot is a pressurized container with a hose and spray nozzle attached. Abrasive media is loaded into the blast pot and sealed air-tight. Once sealed, the media is pressurized utilizing compressed air. A valve on the end of the hose is controlled by the operator. When the valve is opened, compressed air forces the media to journey down the hose and spray out the nozzle.
