• The Nitrogen Sludge Sucker and Blaster Maintenance Kit was specifically designed for multiple uses in the HVAC/R and Maintenance Industry.
• Nitrogen Regulator with protective rubber gauge boots - Maximum Delivery Pressure up to 400 PSI.
• Purging copper lines with low pressure nitrogen displaces the oxygen, preventing oxidation and the resulting scale.
• Pressure testing a system for leaks prior to evacuating and charging will save time and money.
• Cleaning a condensate drain line is easy with a Sludge Sucker or Sludge Blaster.

Product Description ------------------- Uniweld 40055 Nitrogen Sludge Sucker Maintenance Kit (Maximum Delivery Pressure 400 PSI). Nitrogen is a dry inert with multiple uses in the HVAC/R and Maintenance Industry. The Nitrogen Sludge Sucker Maintenance Kit was specifically designed for the following applications: Purging copper lines with low pressure nitrogen displaces the oxygen, preventing oxidation and the resulting scale. Scale left inside the tubing can cause blockage within the TXV Valve and other A/C system components. Pressure testing a system for leaks prior to pulling a vacuum and charging the system with refrigerant will save time and money. Cleaning a condensate drain line is easy with the use of a Sludge Sucker or Sludge Blaster The Sludge Sucker is a tool that was developed to clean out a condensate drain line without having to access the drain pan located in the A/C System's Air Handler. The Sludge Sucker's clear vinyl hose is attached to the 3/4 Inch PVC condensate drain line on the outside of the building. With the use of Nitrogen, CO2 or water suction is created that pulls all the sludge and algae from the drain pan and drain line.
