Des Champs HVAC Air-Trap™ waterless trap allows liquid condensate to drain from the HVAC equipment and simultaneously prevents air from entering or escaping from the equipment.
P-Series
Why a Waterless Trap?
Typically, HVAC equipment is fitted with “P” traps that require water, or another liquid, within a standpipe to prevent gas from entering or leaving the unit. As a result, the “P” traps are susceptible to freezing - expansion - bursting. At other times, the traps dry out allowing gas to escape or enter the HVAC equipment. The Air-Trap™ never requires addition of water to prevent unwanted air leakage.
• The Air-Trap allows water to drain from the HVAC equipment.
• Prevents air from entering or escaping from the equipment.
• The Air-Trap operates dry when no water removal is required and wet when it is required.
• P-Series Air-Trap requires no water head to cause the trap to operate. Simply come out of the plenum condensate line and go down into the P-Series Air-Trap. Come out of the trap and go horizontally with your drain line. The height requirement then becomes the height of the trap plus two elbows.
• When removing water, the water exits the unit but no air escapes the unit.
• Reduces sludge buildup that normally accumulates in standard “P” traps.
• Prevents problem with standard “P” trap never filling with water when condensate begins to form at the beginning of the cooling season.
• Prevents freezing of trap during cold periods since there is no water in the trap.
Note: The attached drawings represent traps that operate under positive pressure. Never connect condensate drain directly to a sanitary drain line.
