SURGEx S20-A is a size A, pre-charged, surge pressure absorber (also called Water Hammer Arrester (WHA) or surge arrester. SURGEx-S series is fabricated from stainless steel grade 304 as standard and is fitted internally with stainless steel bellows. The end connection of SURGEx-S20-A is male threaded size ¾” according to NPT. SURGEx-S series can withstand pressures up to 400 PSIG (27.6 BAR) and temperature range from -100°F to 300°F (-73°C to 149°C).

OPERATION
SURGEx-S series water hammer arresters use stainless-steel bellows as the main component to absorb the shock waves caused by water hammer. When a water hammer occurs, the bellows compresses as water rushes into the arrester, creating a cushioning effect that absorbs the pressure surge. As the water flow slows down and pressure stabilizes, the bellows returns to its original position, ready to absorb the next water hammer.

      Weird smell and reduction in air flow
      The filter has a strange smell to it which I am not sure if mentioned in the description. It also seemed to reduce air flow due to the addition of the carbon pellets. Had to run the fan on full to get same amount of air flow usually occurring on 3.

      Weird Smell
      Good for but the carbon has a weird smell. I have a sensitive nose and I'm not a fan. Going to replace with a regular filter without the activated carbon.
