  • More details

The 3-Way Acid Airless Foamer is a foam applicator for applying 3 highly corrosive chemicals, such as those used to remove concrete and for aluminum brightening, without compressed air.

This acid-resistant venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend a high concentration of acid into the water stream to create a strong solution. The solution then flows through the discharge hose to the "airless" foam wand which draws in atmospheric air to create and project wet, clinging foam on to any surface. Use the chemical ball valves to inject the 3 chemicals separately or simultaneously. Apply Acid based chemicals to spray & Foam it for quick coverage.

Safety & Operational Precautions

When connecting to a potable water supply follow all local codes for backflow prevention.
For proper performance do NOT modify, substitute nozzle, hose diameter or length.

Manufacturer assumes no liability for the use or misuse of this unit.
Wear protective clothing, gloves and eye wear when working with chemicals.
Always direct the discharge away from people and electrical devices.
For pressures over 100 PSI, remove the discharge valve or lower pressure.
Never leave inlet ball valves on when unit is not in use.
Follow the chemical manufacturer's safe handling instructions.
NEVER mix chemicals without first consulting chemical manufacturer.

TO INSTALL (REFER TO DIAGRAM -SEE SLIDESHOW.)
If you are connecting to a potable water supply follow all local codes for backflow prevention.
1. Mount the unit to a suitable surface above the chemical supply to prevent siphoning.
2. Connect the discharge hose(s) as shown in the diagram.
3. Flush any new plumbing of debris before connecting water.
4. Connect water supply. If water piping is older, or has known contaminants, install a water filter.
Set the chemical dilution ratio by threading one of the color coded metering tips into each chemical check valve.
For the strongest dilution ratio do NOT install a colored metering tip.
The dilution ratios in the metering tip chart are based on water thin chemicals with a viscosity of 1CPS.
Thicker chemicals will require a larger tip than the ratios shown in the chart.
Application results will ultimately determine final tip color.
Select the tip color that is closest to your desired chemical strength and thread it into the tip holder. DO NOT OVER
TIGHTEN.
Push the chemical tube over the check valve barb and place the strainer in the chemical concentrate.

TO OPERATE
Always make sure the discharge ball valve is closed or pointed in a safe direction before turning water on. Ball valve can be shut off at any time during operation but should not be left unattended for long periods of time.
1. Open the inlet and one chemical ball valve then open the discharge ball valve to begin application.
2. When application is completed, close the discharge ball valve, return to the unit and close the inlet and the
chemical ball valve.
3. If applying additional chemicals repeat step 1 & 2 for each.
4. When final application is complete close inlet ball valve, re-open then close the discharge ball valve to relieve
pressure in hose. If applicable rinse the work surface before it dries.
