Never Freezes - Never “Dries” Out!

The Air-Trap™ allows liquid condensate to drain from HVAC equipment and simultaneously prevents air from entering or escaping.

Patented US10775073B2

Des Champs Technologies, LLC has recently introduced the versatile RLC-HF Series HVAC Air-Trap. The HVAC Air-Trap uses the air pressure generated by the fan, or gravity, to prevent air leakage from or to the air handler. The RLC-HF Series can accommodate PVC drain pipe sizes from 1 ¼ to 2" and up to 40 tons of refrigeration.

When oriented in the horizontal position, it can accommodate any HVAC unit's negative plenum pressure and requires less than half the installation height of a standard P-trap. The lower height allows ease of installation and, in many cases, reduces curb height requirements or, in some cases, eliminates the need for a curb. In addition, the RLC-HF Series eliminates the following issues associated with the P-trap:

• Never requires priming or filling with water.

• Since it operates dry when there is no condensate being produced, the trap and the drain line leading to the trap will not freeze

• There will be no geyser effect within the HVAC unit at the beginning of the cooling season, as is common with a dry P-trap

• Because the trap operates dry when no condensate is flowing, there will be no sludge accumulation.

• The HVAC Air-Trap is predesigned, so errors caused by field-designed P-traps are eliminated.

Note: The attached drawings represent traps that operate under negative pressure. Never connect the condensate drain directly to a sanitary drain line.

The flammability rating is UL94 V-0.
