as long as the extracta can suck more volume of air away than the gun in cabinet can produce and u can exhaust clear to outside building theres no problems i use a woodchip extracta on mine. it can clear 28cfm of air at 90psi no problem without any presure in cabinet just make sure cabinet isnt leaking dust when in useI know i can use it but with it being silica, i am using a hoover a collector and my cabinet is a oil drum, are there any precautions to be using kiln dried sand????
