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.

Clips must be installed correctly for trap to function properly

No More Troublesome "P" Traps
• The Air-Trap will never freeze and break
• No more issues caused by traps drying out
• Air-Trap is predesigned to prevent field errors
• Air-Trap reduces trap height by up to 60%
• Eliminates sludge build-up at bottom of “U” tube
• No more geysers when there is negative pressure
• Easy maintenance – use the side clips to open the Air-Trap for cleaning

The Air-Trap™ concept has been incorporated into IAPMO IGC 196-2018 Standard for Condensate Traps and Overflow Switches for Air-Conditioning Systems.

Seems to be a good replacement for a standard trap

I ordered a FCN-series trap for my main AC drain line to replace a standard trap that had burst over the winter (AC is in the attic). I have not noticed any issues, trap filled with water, seems to drain as it should, and there has been no backup or strange occurrences. I only hope that come winter it drains enough water from the line that it will not burst like a standard trap (currently it sits water filled which makes sense since it's on the negative pressure side). I purchased the FCN series at the suggestion of the company, it seems to be overkill based on fluid flow but it seems more robust than the RLC series. I bought a RLC as well as a trap for my overflow/emergency drain side of the AC since I wouldn't expect it to be draining much or at all except in an upset situation.

Good - could be better

Appears to be a good solution. Could be better by: 1. replace center clips with a screw-on connection like a pvc union. would reduce/eliminate possibility of clips being pulled apart as mentioned in the installation instructions and 2. provide a way to clean on the upstream side of the 3/8" hole as debris could get struck there.

money saver

just paid 423$ hvac call for stopped up water trap on unit .
thought having paid for preventive maintence with hiller hvac that original p water trap would would not dry and clog during summer usage.. costly education
