In addition to regulating the pressure of the gas, gas PRSs also play a role in filtering and conditioning the gas. Filters are used to remove impurities, such as dirt, moisture, and debris, from the gas before it is distributed. This helps to prevent damage to pipelines and equipment, as well as ensure the quality of the gas being delivered. Conditioning equipment, such as heaters and coolers, may also be used to adjust the temperature of the gas to meet specific requirements.
