Nitrogen accumulators are used inline with the pressure pump to absorb pulsation that develops in the pump head, ensuring a smooth even pressure at the tool. Angled adapter is included for installation.
Pulsation at the solution hose or tool is usually a good sign that the accumulator should be replaced. Manufacturers recommend replacement should take place every 1,000 hours of operation or every year, which ever comes first. Recharging is not an option on this particular unit.
