N-Series HVAC Air-Trap™: Negative Pressure Waterless HVAC Condensate Trap

Volume Pricing is Available - Please email info@waterless-trap.com for a discount code. Never Freezes - Never “Dries” Out! The Air-Trap™ allows liquid condensate to drain from the HVAC equipment and simultaneously prevents air from entering or escaping from the equipment. Patented US9777957B1 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.One of the advantages of the Air-Trap “N-Series” waterless trap is that it operates in a horizontal position. Horizontal operation allows the center line distance between the unit drain connection and the trap to be the same or greater distance in inches as the negative pressure in inches of water colum
