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.

      Excellent quality
      Size: Large, Color: Purple
      Perfect tuxedo to use for many functions. Got it about 2 years ago and have used it probably twice for galas as well as awards programs. Fits to size and didn’t break the bank. Texture is good and it is easy to pair with anything as well as is reusable.
