A natural gas booster is used to boost the pressure of natural gas above what is provided by the service line. Natural gas boosters can provide high-pressure gas up to a maximum of 36,000psi.
There are two main types of natural gas boosters: shaft sealed and hermetically sealed. Shaft sealed gas boosters require a shaft seal which must be maintained regularly to prevent leakage.
Hermetically sealed gas boosters don’t require any seals and are completely air-tight by design. For these reasons, hermetically sealed boosters are more efficient and reliable.
A hermetically sealed gas booster also cuts costs in the long run because there is very little maintenance required. When maintenance is required, it’s easy to do because the motor and rotor can be removed without disturbing any piping.
