Dead band This is the area in time between pulling the trigger on the spray gun and the pump staring to pump again. Most mechanical pressure controls allow about a 300 psi drop in pressure before turning the pump on. Graco's SmartControl is an electronic pressure control that reduces this pressure drop to about 50psi. The second generation, Smart Control 2.0, reduces this even further to a near zero dead band.

The dead-band results in a fading spray fan followed by a burst to the full, set pressure. The dead-band is more noticeable when spraying thinner materials and/or at lower pressures. The EPC gives a more consistent and even fan pattern and eliminates a few moving parts which can result in less long-term maintenance costs.
