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.
Negative Pressure Orientation
Positive Pressure Orientation
Features
• Condensate flow up to 0.8 GPM at 2" negative pressure
• Schedule 40 PVC with easy maintenance, side clips to open the Air-Trap for cleaning
• Retains no water after condensing has ceased
• 3/4" internal slip or fitting (can connect to 1/2" via reducer coupling)
• Perfect for ductless mini-splits
• Meets general building codes. For use on HVAC equipment only. Not for use as a sanitary trap.
• Meets code IMC Section M307.2.4.1 for Ductless Mini-splits

FCN-Series Operation
When condensate IS NOT present, the ball sets tightly against the seat.
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
•Perfect for Ductless Mini-splits

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.
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.
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
Works good
Excellent it solved my problem with the splits
