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 column within the negative pressure plenum for which the AHU drain is connected.

N Series Negative Pressure Waterless Trap by Des Champs Technologies

Figure 1 shows that for a “P” Trap the vertical distance required between center lines of unit connection and the center line of the bottom of the trap is 4 inches when there is a 2-inch negative plenum pressure. Not for the N-Series, it is only 2 inches, not the 4 inches required with the standard “P” trap.

When there is no water to remove the negative pressure within the plenum draws the internal mechanism against the valve seat and essentially no air enters the AHU through the drainpipe.

When condensate forms then water builds up in the vertical pipe. When the water level equals the negative air pressure, in inches of water column, the force of the water head becomes equal or greater than the negative pressure, the internal mechanism moves to the right and rests against the stainless steel through pin and water flows.

N-Series HVAC Air-Trap™ - Negative Pressure Waterless Trap allows liquid condensate to drain from the HVAC equipment and simultaneously prevents air from entering or escaping from the equipment.

When there is no longer a requirement to remove water then the negative pressure returns the ball to the valve seat and prevents airflow to the unit plenum. The internal rails aid in returning the ball to the seat in case the variable speed fan is operating at a low flow and low negative pressure.

Flammability rating is UL94 V-0
