  • More details

The Portable A-25 Uni-Body Airless Foamer is a medium volume foam applicator featuring an all stainless steel cart assembly.

 It will project foaming chemicals on to any surface up close or at distances up to 6 feet without compressed air. This venturi injection system uses standard city water pressure (35 -125 PSI) to draw and blend chemical concentrate into the water stream to create an accurately diluted 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.

Lafferty Airless Foamers do not require compressed air, eliminating cost and equipment adjustment issues. Foam is created instantly by the venturi airless foam wand.

Choice of two flow rates provides for quick area coverage for small or large applications. Foam throws distance of up to 8 ft. for A-25 models and up to 10 ft. for A-50 models —
Increased water pressure will increase foam throw.

Attachments: discharge Hose 19mm x 7.5m + complete Foaming Gun & color-coded metering tips for up to 21 dilution ratios.

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.

1. Place a container of chemical concentrate in the jug rack(s).
2. Connect water supply. To prevent blocking the small water jets in the injector body flush any new plumbing of
debris before connecting.
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
Push the chemical tube over the check valve barb and place the strainer in the chemical concentrate.

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 ball valve then open the discharge ball valve to begin application.
2. Make final metering tip adjustments based on application results.
3. When application is completed, close the discharge ball valve, return to the unit and close the inlet ball valve. Re-
open the discharge ball valve to relieve pressure in hose then close the discharge ball valve. If applicable rinse the
work surface before solution dries.
