NB Series – Vacuum Boosters

Wide Capacity Range

The NB series Roots-type vacuum booster is available with optional features, such as single-point mechanical seals, oil slinger ring seals, five-point mechanical seals, and labyrinth seals to reduce contamination and oil consumption. The booster comes with internal coating protection for corrosion resistance, making this apparatus particularly suitable for harsh process gasses such as those in the petrochemical and pharmaceutical industries. From 100-60,000CFM and 3-150HP, the NB Series is comparable with the entire span of MD Kinney vacuum booster models. This line of robust vacuum boosters is suitable for working conditions of high temperature, high differential pressure, and high vacuum level.
