This dust collector and machinery interlock is ideal for shops where machines are used intermittently. It automatically starts when any machine is switched on, eliminating the need for running control wires to every machine in the shop. The "Dust Switch" makes sure the dust and chips are filtered away from equipment and the work area, reducing the risk of fire or explosions. The unit works with 120/230/460 V single or three phase power and insides a standard board with inputs for up to five sensors.
