Hi, I’m Paul. I’m the technical project manager here at BlastOne, and today we’re going to be going over the blast recovery system 3.5.
Let’s get it.
This is the blast side of our blast recovery system. You’ll notice an inlet to isolate or bypass the regulator, allowing you to control your blast air system using this or the regulator. Here we have a ComboValve, a major component that keeps our air compressed and abrasive flowing.
Common field issues include worn-out hoses or ComboValve seals, causing significant blow-by through the hose and preventing the piston from pressing far enough, resulting in air trickling out. This creates negative differential pressure, hindering abrasive flow and leaving you with just air at the nozzle, making the system counterproductive.
This is a 3.5 setup. Here, abrasive drops through and filters out big debris with a grate or screen, preventing them from entering the blast port. Below the blast port, we have the TeraValve metering valve where you can connect your hose.
One key component is the inductor with a venturi nozzle inside. Inlet air creates a vacuum through the venturi nozzle, drawing vacuum from here and exhausting it through here.
This is the vacuum side of our blast recovery system with a five-micron filter preventing hazardous dust from entering the atmosphere. The dirty side of the vacuum collects dust and debris in the cam lock, which you can clean out by removing the cap. The clean side of the vacuum must remain free of debris and hazardous waste to prevent atmospheric contamination.
Typical field issues include ComboValve or blowdown hose wear, preventing proper abrasive flow due to improperly pinched hoses and incomplete seals. This results in small leaks at the top of the abrasive vessel, reducing pressure and abrasive flow into the metering valve.
We have a control valve with air in and air out. Debris can sometimes cause the plunger to stick open, keeping the auto air valve and TeraValve open. This can lead to issues like runaway pots, where the pot doesn’t shut off. The quick field fix is to remove the cap, clean the debris, apply chapstick, and resume work.
