TYPICAL APPLICATION The air valves break the vacuum formation and enhance the efficiency of water draining of the filtration system.
FEATURE & ADVANTAGE
• Big size air inlet allowing large flow;
• PP material with corrosion, acid, alkliane resistant features to be long lasting;
• Compact structure & simple design & durability;
HOW IT WORKS Filtration system under pressure condition: When the filtration system works under pressure, air will gather at the bottom of chamber, then the float will move up to seal the inlet.
Filtration system in empty status：When the system or pipe is drained empty, negative pressure forms in the air valve. Meanwhile the float move down to take in air against vacuum formation.
