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: US10775073B2 

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.

FCN-Series Operation

HVAC Air-Trap FCN-Series Negative Pressure Waterless HVAC Condensate Trap - Perfect for Ductless Mini-splits

When condensate IS NOT present, the ball sets tightly against the seat.

HVAC Air-Trap FCN-Series Negative Pressure Waterless HVAC Condensate Trap - Perfect for Ductless Mini-splits

When condensate IS present, water pressure moves the ball away from the seat.

Worked perfectly!

My old p-trap broke and it took me a while to dig it out of the ground. I didn't want to buy the parts to replace it, so I searched for a better solution. I found the waterless trap. It arrived quickly, and it fit perfectly on the original pipe, which was great. I turned on the A/C and gave it a try. The little red ball stopped air from entering my system, and when the unit shut off, the little red ball released and the condensation water started running out the end of the valve just like it was supposed to do. I was thrilled! If your old p-trap is broken, this is your perfect replacement. No more burying pipes in the ground, and it really does work perfectly.

Simple and brilliant

This concept is new to me, but makes sense on all levels. I plan on using these for installations and service calls.
