No, since the MMA and the BPO on separate hoppers no cleaning requires, just clean the end of the gun cap and spray nozzle with acetone.
Most suppliers do not have the Aggregate pre-mixed with the MMA.
We recommend Corundum, Aluminium Peroxide, and Sand. The size of the aggregate can be up to 2mm.
The lifetime of the pump is depending on the turning speed and kind of aggreged used.
Normally the aggregate will not separate while you are using the machine. It will only separate and sink to the bottom if material is left in the hopper for several days.
Yes, you can. However, be sure not to go all the way to the bottom since there is the connecting shaft turning the pump.
You clean only with acetone.
You clean with mineral spirit that the VOC is more then 600 (never with acetone will damage the pump) or high-pressure water.
As you will only use 2oz of BPO per gallon of MMA while operating the machine, it is not required to fill the entire 10 gallons with PBO.
Yes, normally when the weather is cold ratio can be change by inserting smaller sprocket on the BPO pump.
The BPO flows on a separate ¼” line all the way to the gun head prior to mixing with the air and flowing though the spray nozzle to mix with the MMA. Since the air pressure for the BPO is much higher than the MMA pressure you should never have back flow of BPO to MMA.
Standard sprayer does not include but can be added for additional fee.
The machine is set up to spray one gallon per minute with a thickness of 60 mill (1.5mm), which should return you about 45 square feet (4.2 square meters) per minute. It is possible to have a higher GPM, but an additional external compressor is needed. The unit is set up that the CFM and the GPM will give a perfect anti-skid finish; any more material flow results in splatter coat finish.
The hopper cannot be removed as it connects directly to all the mechanicals component to turn the pump in the front of the machine.
Machine warrantee is 2 years excluding normal worn-out parts during use.
