Airtec Products Corp., now offers EZ Trap^® UltraSwitch Model EZT-356, the HVAC/R industry’s only self-evacuating overflow cut-off switch with an integral mini pump to help prevent property damage from condensate drain pan overflows on residential and commercial air conditioners.

When connected to an air conditioner’s overflow outlet with a connecting one-inch-diameter PVC fitting, the EZT-356 senses a rise in potential property-damaging condensate levels caused by a blocked outlet. Blocked drain pans are evacuated at a rate of two gallons/30-seconds by the heavy-duty 24-v integral Aspen pump, which was designed exclusively for the patented EZT-356.

Most mechanical overflow switches use a float switch mechanism and only momentarily deactivate the air conditioner in situations of partially blocked drains. Conversely, the EZT-356 uses stainless steel electronic probes to sense rising condensate levels. The EZT-356 deactivates the air conditioner while the integral mini pump evacuates the excess condensate into its own 3/16-inch vinyl tubing drain line. The pump remains live as a second line of defense for instances such as a deactivated air conditioner’s iced coil, which can potentially thaw and overflow a blocked drain pan.
