The dust collection system is all home made including the automated Rube Goldberg blast gates. These are powered by 25lbs of compressed air and are actuated by a two way solenoid refrigeration valve. The actuator is a 3/4" air piston. The blast gate itself is a 4" from the Penn State tool catalog. The springs were from a flea market. The valves and pistons were from Mendelsons Surplus. I installed a relay in each stationary tool so when powered up, it closes the circuit and opens the refrigeration valve which allows air to pull open the blast gate. After the gate is fully opened, a small micro switch closes a circuit that energizes a relay that sends power to the dust collection motor. As the gate is de-energized the residual air is passed back into the other side of the piston keeping dust from getting into the piston. I found that if it weren't for the automated blast gates, the dust collection system would never get used. This is a fun woodshop. The real ordeal happens in the finishing room. This is also where the real miracles occur.
