Patented US11231203B1 A new concept in condensate trap design permits condensate removal from AC or other condensing equipment while blocking airflow all year and requires only 2 7/8" height for positive 0-40" WC pressure (PLP-084) and 2" for the smaller 0 to 6” WC pressure (PLP-051). They will never “dry out” or freeze because they do not  depend on water to seal, only fan pressure. For a hundred years the P-Trap, a carryover from use on toilets and sinks, has been used on AC equipment to prevent air loss. Unlike the P-Trap, the PLP was designed specifically for HVAC equipment and does not require standing water to prevent air leakage. AC equipment produces condensate mostly during summer. During the remainder of the year, little or no condensate is produced, and the P-traps dry most of the time. When they do have water, the bottom of the trap is prone to dev
