Sandblasting Booth

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.

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.

Floor Recovery Hoppers Installation

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.

Excavated or Above-Ground 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.

Dimensions of Recovery Hoppers

Dimensions of recovery hoppers can vary from 10 feet in length for compact installations to over 200 feet for high throughput industrial blasting facilities.

Steel Grating Protection

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.

Steel Grating Protection for Excavated Floor Hoppers

Floor Coverage of Recovery Hoppers

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.

What is the Ideal Floor Recovery Hoppers Layout for my Application?

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.

  • No excavation required
  • Hopper must be loaded mechanically with a loader
  • Loader is required

Media Recycling System

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.

Pneumatic or Mechanical Abrasive Recovery System?

There are several factors to take into account when choosing the right abrasive media recovery system for your application:

  • Your budget and expected return on investment: Mechanical Systems are more expensive to implement, but they become cheaper on the long term when considering overall process costs of operation and maintenance;
  • The objective of your sandblasting process: Surface preparation prior to coating versus blast cleaning for removing paint, rust, scale, etc. the process by-products and contaminants produced are a significant factor when debating between a mechanical or a pneumatic recovery system;
  • The blast media required for your application: Heavy blast media such as steel grit and steel shot cannot be conveyed in a pneumatic abrasive recovery system;
  • The production space available in the shop: Pneumatic systems require lower ceiling height and smaller footprint compared to mechanical systems;
  • Whether or not you are allowed to excavate in your building: Excavated mechanical system requires at least a 5 feet excavation for in-ground installation;
  • And many other factors – such as the expected recovery rate, the frequency at which you plan on cleaning the floor between jobs, whether or not your application is producing combustible dust that must be exhausted outside the building, etc.

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.

Abrasive Media
  • Light-to-medium abrasive media only (not suitable for heavy media such as Steel Grit)
  • Can handle all types of abrasive media

All our blast booths are delivered with a high-performance DCM2000-50000 Series cartridge type dust collector.

Standard Filtration Capacity

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.

Advantage of the Vertical Design Cartridge System

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.

Automatic Reverse Pulse Cleaning System

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.

Easy Maintenance

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.

Airflow Inside the Sandblast Room

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.

Sandblast Booth Air Inlet PlenumsAir Inlet PlenumsSandblast Booth Air Outlet PlenumAir 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.

Pressure Sandblasters for Sandblast Booth

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.

Pressure Hold or Pressure Release System for Pressure Blast Pots?

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.

  • Offers the advantages of both systems without the compromises

Remote Depressurization Switch

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.

Remote Depressurization Switch for Sandblast Booth

Remote Blast On / Air Only Switch

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.

The main benefits of blasting in a sandblast booth are:

  • Increased Productivity: Allowing you to blast indoors 24/7, regardless of outdoor weather conditions, in a very controlled environment. Also, providing a better process integration with pre-and post-processes such as the application of coating and painting without exposing your parts to harsh conditions that may deteriorate their
  • Enhanced Process Quality: No cross contamination due to humidity, rain, or other foreign particles. Also, the blasting equipment, including the nozzle, remains in optimal working condition.
  • Economical Process: Most popular abrasives – such as glass beads, aluminum oxide, steel shot, and steel grit – can be collected from the floor, restored, and recycled for further blasting operations. Some blast media can be reused hundreds of times before it breaks down into dust, allowing for significant savings.
  • Operator Comfort and Safety: The blaster can be fitted with the most advanced respirators and air filtration systems that filter and monitor airborne contaminants, supplying the operator with pure, Grade-D breathing air. Air supplied to the respirator can even be heated or cooled for optimal comfort during long blasting operations.
  • IST Care Preventative Maintenance Program (PMP) – The IST PMP program provides four certified IST Technician visits to keep your system in top running condition and avoid unplanned maintenance downtimes for two years following the installation. The purchase of a PMP program also extends the standard 1-Year warranty to an extended 2-Year warranty in order to guarantee the smooth running of your systems and avoid unplanned expenditures.
