Overview
The Portable Uni-Body DEMO Foamer is a combination foam / spray applicator for demonstrating foaming or non-foaming chemicals being applied to any surface. Featuring an all stainless steel cart assembly, 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. Use the foam wand and nozzle for rich, clinging foam created by injecting compressed air into the solution to greatly increase volume and coverage ability. The foam is then projected through the discharge hose and fan nozzle at distances up to 12 feet. Use the airless foam wand to demonstrate wet, clinging foam without compressed air or use the spray nozzle to apply chemicals as a fan pattern spray.
Safety & Operational Precautions
To Install (refer to diagram on next page)
Set the chemical dilution ratio by threading one of the color coded metering tips into each chemical check valve. See chemical labels for dilution ratio recommendation or consult your chemical supplier.

Problem | Possible Cause / Solution | |
---|---|---|
Startup | Maintenance | |
A) Foam surges and/or hose "bucks". B) Foamer will not draw chemical. C) Foam too wet. D) Foam does not clean properly (too dry). E) Using too much chemical. F) Water/chemical backing up into air line. G) Water backing up into chemical container. H) Air/chemical solution backing up into water line. | 1, 2, 3, 4, 6, 7, 8, 9, 10 1, 3, 4, 7, 8, 9 2, 3, 4, 6, 7, 8, 9, 10 1, 4, 6, 11 5 |

PREVENTIVE MAINTENANCE: When the unit will be out of service for extended periods, place chemical tube(s) in water and flush the chemical out of the unit to help prevent chemical from drying out and causing build-up. Periodically check and clean chemical strainer and replace if missing. |
