Smith Equipment (www.smithequipment.com) says its new gas manifold and automatic changeover regulator system provides accurate, uninterrupted gas flow. The nickel-plated system is equipped with 2.5-in. chrome-plated gauges that allow operators to check cylinder bank and outlet pressures visually; and an optional audio and visual alarm that alerts operators when a gas cylinder bank is nearing empty. Regulator models are designed for 15 psi, 40 psi, or 125 psi outlet pressures.
