BLASTING EQUIPMENT & SUPPLIES
Sandblast Booths (Blast Booths or Abrasive Blast Rooms) provide the ideal confined environment for an abrasive blasting operation of relatively large pieces or for high-productivity sandblasting. They are designed to optimize the sandblaster’s productivity while reducing downtimes as well as the cost of operation and maintenance of sandblasting-related equipment.

Blast Booths consist of a few key components and layout options which will be discussed below.
The ISTblast standard blast booth enclosure consists of modular 10- or 14-gauge galvanized steel panels. They can be easily assembled with supplied nuts and bolts. The walls and roof are supported by structural beams tailored to the room size and the required bearing capacity.
Different industrial-grade steel gauges are available upon request for larger rooms. Steel panels are available in natural galvanized steel or powder coated finish.
Rubber lining protection is available for interior walls and doors for long-lasting life. Without lining protection, blast streams could rip off the functional coating from panels and cause premature wear and corrosion on the surface. ISTblast’s exclusive rubber lining design makes it easy to install and replace the rubber sheet as the room ages.
The sandblast room is supplied with at least one standard access door.
Optional bifold or trifold access doors are available when floor space is a constraint. Drive-thru sandblast rooms are available with an additional door at the opposite end of the room when required by production layout.
Optional heavy-duty rubber roll-up door system is also available for limited space installations or to speed up the opening/closing door procedures.
Personnel doors and observation windows come in standard 36″ x 84″ to facilitate access to the sandblast room. They also increase the blasters’ safety in case of emergency. Depending on the size of the sandblasting room, additional personnel man doors may be required.
|Outside the room||Inside the room|
The abrasive blast room is lighted with a high-efficiency Hi Bay 18,000 lumens LED lighting system. ISTblast’s unique light design allows for one-man installation, cleanup, and replacement of the light from inside the room. No need to climb up on the roof nor allocate two resources for servicing or cleaning the light.
The operation of critical components is fully automated by a Programmable Logic Controller (PLC) and interfaced with an intuitive Human Machine Interface (HMI) touch panel.
A maintenance program integrated into the system will prompt message reminders when it is time to perform a check or maintenance routine on components such as the dust collector, abrasive recovery system, etc.
The abrasive media recovery system efficiently reclaims and recycles used blast media after blasting process. First, it collects residual abrasive media remaining on the floor after blasting operations. Then, it moves it to a media reclaim system where dust and foreign particle matters are filtered out and diverted away to the dust collector. Then, only media in good working condition is returned to the pressure blast pot.
The key advantage of the media reclaim system is achieving substantial savings and protecting our planet by considerably reducing our abrasive media consumption. According to the application and the type of media used, recycling rates of over 95% can be achieved.
Here is what you need to know about choosing the right media recovery system for your application.
After blasting operations, used abrasive media must be swept or shoveled into recovery hoppers. Hoppers may be excavated into the floor or installed over the floor in surface installation.
Above-floor installations do not require any excavation, but they require much more effort from the operator who must shovel the blast media into the pit rather than simply pushing it into the excavated hoppers located below floor level.
|Excavated Floor Installation||Surface Installation|
Dimensions of recovery hoppers can vary from 10 feet in length for compact installations to over 200 feet for high throughput industrial blasting facilities.
Floor hoppers are protected by removable steel grating rated to 1,000 lbs. per square foot. Other capacities are available to allow lift trucks and other material handling equipment to circulate over them.
Underneath the steel grating, a mesh screen allows for the collection of large debris before the enter the recovery system.
Complete in-floor hoppers (excavation required) are more expensive, but they provide an automatic and continuous recycling of the blast media without the need to load the collection hoppers manually.
On the other hand, partial floor hoppers and corners require the operator to sweep or shovel the abrasive media into the hopper.
Depending on your application, abrasive media, available production space, and budget constraints, there are various types of blast room recovery systems and floor layouts available.
In brief, here are the pros and cons of common layout options.
|TYPES OF INSTALLATION||PROS||CONS|

|HOPPERS ABOVE GROUND|
Once the blast media is collected, it is then moved to a media reclaiming system where dust, shattered media pieces, and other contaminants are removed, leaving only media in optimal working conditions.
Depending on the application and the abrasive used, approximately 95% of the dirty abrasive media mix will be recovered and returned to the pressure blast pot for further use. The other 5% is simply exhausted to the dust collector and collected in a dust barrel.
Typically, ISTblast offers three standard Abrasive Media Recovery Systems.
|Types of Abrasive Recovery System||Means to collect used abrasive media from the floor||Mechanical Separation of Media and Dust|
|Pneumatic||Urethane Suction Pipe||Cyclonic Separator|
|Mechanical||Screw Conveyor & Bucket Elevator||Air Wash Separator|
|Hybrid||Screw Conveyor & Urethane Suction Pipe||Air Wash Separator|
There are several factors to take into account when choosing the right abrasive media recovery system for your application:
Here is a comparison chart of the main factors to be taken into account for making the right decision between a pneumatic, mechanical, or hybrid blast room recovery system.
|Media Recycling Rate|
All our blast booths are delivered with a high-performance DCM2000-50000 Series cartridge type dust collector.
Standard ISTblast cartridge media is able to capture 99.9% of particles down to 1 µm. Optional cartridge media with higher filtration capacity are available upon request.
The vertical design of our dust collectors provides more efficient pulsing of dust, eliminating uneven dust loading associated with horizontally mounted cartridges. Also, they require less attention and care since the vertical cartridges do not require rotation to ensure uniform wear on the entire surface.
This DCM Series dust collector features an automatic, programmable reverse pulse cleaning system for cartridges. The cleaning process is monitored and triggered by means of a digital pressure differential indicator that oversees the deterioration of the cartridge filtering efficiency.
The cartridge replacement process is effortless and accessible by the front door. The operation and the cleaning process of the dust collector are fully automated and controlled by the sandblast booth PLC.
The main access door is usually fitted with two air inlet plenums, and the opposite wall has an outlet plenum to allow even air circulation from one end of the abrasive blast room to the other.
|Air Inlet Plenums||Air Outlet Plenum|
Air inlet and outlet plenums are equipped with adjustable deflectors to maintain a well-balanced airflow inside the sandblasting booth. Airborne contaminants travel through a ductwork linking the outlet plenums to the dust collector, where it can be collected into a dust barrel.
An even airflow provides great visibility to the blaster by drafting away the dust cloud generated from the impact of the blast media onto the workpieces. It also helps reducing premature wear on mechanical components.
ISTblast offers a wide range of Pressure Blast Pots for new and existing blast booth installations. Available with tank capacities ranging from 3.5 cu. ft. to 10 cu. ft., they can accommodate one or two operators at the same time.
In most installations, we are able to fit a storage hopper between the media separator and the blast pot to provide long hours of blasting autonomy. Blasting facilities can be designed to allow up to four operators to blast at a time.
In the field, most pressure blasters are Pressure Hold Systems meant to increase the blaster’s productivity by maintaining the pressure inside the blast pot when the Deadman control is released. Otherwise, each time the remote control is released and re-engaged, the system would take 10-15 seconds to build back the pressure needed to produce an effective blast media stream. This results in downtimes, loss of productivity, and inefficient consumption of compressed air.
On the other hand, the blast pot has a certain blasting autonomy. Once it runs out of media, it must release its pressure in order to allow the plunger fall down and refill the tank with abrasive media. In the Pressure Release System, this occurs every time the Deadman control handle is released. But really, how frequently do you need to refill the pot during a job?
So, which system is better for a sandblast room? The answer is BOTH!
The Double Control System has all the advantages of both systems. It maintains the pressure when the Deadman control is released to facilitate frequent start/stop operations. It also allows the operator to release the pressure and refill the pot from a switch located inside the sandblasting booth, without the need to remove safety equipment and reach for the depressurization valve manually on the blasting machine located outside of the blast booth.
|RC-176 Pressure Release System||RC-186 Pressure Hold System|
|RC-176/186 Double Control System|
The depressurization switch located inside the abrasive blast booth allows the operator to release the pressure inside the blast pot and fill it up with abrasive media contained in the storage hopper.
This operation can be accomplished without the hassle of leaving the sandblast room and taking off the safety equipment, resulting in increased productivity and reduced downtimes.
This option is available exclusively with Double Control System configuration for Pressure Blast Pots equipped with a media storage hopper.
The Blast On / Air Only Switch allows the operator to cut off the abrasive metering valve and leave on the air valve from inside the sandblast room.
This feature enables the operator to use the blast hose as a powerful air blower producing high-velocity compressed air to blow dust off the workpiece, as well as clean the floor by blowing abrasive media remains towards the floor hoppers.
This option is available at a low cost and results in exceptional productivity gains, along with reducing physical efforts from the operator.
