There are a number of factors to consider when adding a blast room or abrasive blasting system to your powder coating or painting operation. No matter what type of dry blasting system you might be considering, this guide is designed to help answer your questions and plan in your success.

Note: Though uncommon, wet blasting systems, additionally known as slurry blasting systems, are typically used. This article focuses on dry blasting systems, significantly those designed for guide blasting by one or more operators inside a walk-in dimension steel enclosure.

Half 1: The Blasting Enclosure
Before deciding on a blast room, it’s greatest to familiarize yourself with among the features widespread across most manufacturers. Virtually all blast rooms characteristic a sq. roof design instead of hip-style roofs. The sq. roof building permits 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 – may not provide the durability and usability you are looking for.

Wall and roof panels are often 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. Everybody desires a heavy duty blast room, however heavier building usually presents no real benefit because high-wear areas are typically covered by rubberized shielding.

Blast rooms are commonly equipped with a moderate number of multi-tube fluorescent light fixtures and feature safety glass with the intention to meet code.

Upgrades To The Blasting Enclosure
While there isn’t a lot to upgrade when it comes to the cabin of standard blast rooms, the door design is one space of the cabin’s construction where upgrades are typically worth the cost. The most importantity of professional-grade blast rooms include typical swinging doors with louvered openings. Premium models could characteristic perforated doors with adjustable splash shields to keep spent media inside the blast room while permitting recent air to be drawn into the enclosure. Ruggedized fabric or rubber roll up doors will be requested at an additional cost. They assist reduce the quantity of shop space required.

A typical blast room ships with one full-width, full-height door set, and will have one or more separate personnel doors. Some manufacturers provide a curtain wall or curtain door option to reduce price, however these configurations will not be in style with most shop owners because they don’t provide as a lot containment as other designs.

Get The Proper Size
Make certain the blast room is the suitable size. Many of the considerations we outlined in our powder coating oven measurement guide might be applicable right here, but make positive you give your elements and your operator plenty of room. For example, if the components you must blast are very tall, consider adding some additional height to the cabin so you won’t continuously be blasting into your light fixtures or the unprotected ceiling surface. Also, if the half you want to blast takes up the majority of the cabin, give your operator further width and size to safely work around the half 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 same 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. As soon as sealed, the media is pressurized using compressed air. A valve on the finish of the hose is controlled by the operator. When the valve is opened, compressed air forces the media to travel down the hose and spray out the nozzle.
