## Description

Product Description Uniweld 40040 Nitrogen Sludge Sucker & Blaster Kit (Max. Delivery Pressure 400 PSI) with Metal Carrying Stand for 40 Cubic Feet Nitrogen Tank Nitrogen is a dry inert gas with multiple uses in the HVAC/R industry. The Nitrogen Sludge Sucker & Blaster 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; then blows it onto the ground outside. The Sludge Blaster is inserted into the drain line (Pipe Capacity: 3/4-Inch to 1-Inch) and expands inside the pipe with the use of nitrogen pressure blasts the sludge and algae free. Capabilities can be expanded with rubber plug adaptors, needle tip, air chuck and accessories purchased separately. Kit Includes: Part No. RHP400 Nitrogen Regulator - Maximum Delivery Pressure up to 400 PSI, 1/4-Inch Male Flare Outlet Connection, CGA580 Inlet Tank Connection and protective rubber gauge boots, Part No. 40000 Sludge Sucker, Part No. 40061 Sludge Blaster, Part No. H5SMY 5-Feet Service Hose, Part No. H2SSM 2-Feet Service Hose, Part No. BG1 Blowgun, Part No. 516 Metal Carrying Stand for 40 Cubic Feet Nitrogen Tank (Tank Not Included - Sold Separately).

## Questions & Answers

**Q: can i fill my king shocks with this tank?**
A: this item does not included the tank.

**Q: It this the nitrogen used to pressure test for leaks of hvac units ?**
A: Yes, works well. But if you want to use it to braze you need to purchase the purge valve separately

**Q: whats included in this sale?**
A: This kit comes with the gauge set and various hoses and adapters and a carrier for the bottle.

**Q: Is this tank DOT aproved to be refiled at a local gas supply.**
A: It does not come with the tank. But it is made for the standard 40cu DOT tank. You can get one at your local welding/hvac supplier. These places usually don't refill your tank for you, they just swap it for a full one, and fill up the empties later...
