Spirax Sarco diffusers create a safer and quieter discharge to atmosphere, helping sites manage noise and high-velocity release around blowdown and drainage points. They are designed for installation on the outlet of steam traps, air vents and direct blowdown valves where uncontrolled discharge would otherwise be noisy, abrupt or erosive. By reducing sound pressure levels by up to 80% at one metre and cushioning the discharge stream, they help protect both people and outlet hardware. That makes them especially useful where condensate or steam is released to atmosphere during normal operation, testing or maintenance procedures. In practical terms, they help turn an otherwise harsh release point into a more manageable part of the wider steam system.
Diffusers are usually the final piece of a wider release arrangement. If the main upstream requirement is controlled blowdown or pressure reduction, compare blowdown valves. Where the outlet belongs to steam-trap discharge or vent hardware, continue into steam traps and air vents.
