HydroFoamer 481

HydroFoamer Sprayers & HydroFoamer Parts - HydroFoamer 481 


HydroFoamer 481 hose end proportioners combine automatic dilution with convenient control of where and how solution is applied.  The HydroFoamer 481 provides a thick, rich foam for more "cling" time on the surface being cleaned. The HydroFoamer 481 provides an excellent way to apply cleaners/sanitizers/disinfectants at metered dilutions.  On and off functions are controlled using a trigger on the spray gun. To rinse, the concentrate container is disconnected via a quick coupler.

Ease of use enhances product performance

HydroFoamers eliminate the time and hassle of manually mixing concentrates, which not only increases labor productivity, but also increases concentrate performance because the solutions are consistently mixed as directed by the manufacturer. Since concentrates are mixed only as they're applied, they are fresh and will perform at peak power, and waste is minimized.

Features & Benefits

  • Proven, reliable components
  • Non-electric
  • No installation required
  • Compact, easy to store
  • Enhanced safety
  • Maximum cleaning product performance

HydroFoamer and HydroSprayer offer easy automatic dilution with

convenient control of where and how solution is applied. On and off

functions are finger-tip, trigger controlled on the spray nozzle. To rinse,

the concentrate container is disconnected using an easy-to-operate

quick coupler, designed to allow either a full width spray or powerful jet

stream while rinsing. This range of control helps personnel apply the

solution where it’s wanted. Handles on larger containers increase the

operator’s control over application.

Operation Instructions

1. Unscrew foamer lid assembly from container.

2. Select a metering tip using the chart below as a guideline and press the tip firmly into the hose barb on the bottom of the lid assembly. Install the suction tube on the hose barb.

3. Fill the container with concentrate. Screw foamer lid assembly securely onto container. CAUTION: Foamer lid assembly must be securely fastened to container to prevent accidental spilling of concentrate during use of foamer.

4. Insert foamer lid assembly into female quick connect on spray nozzle.

5. Connect a garden hose with 3/4" male garden hose thread to the base of the spray nozzle handle. Turn on the water supply to the hose. (Minimum 25 PSI water pressure is required to operate the foamer.)

6. Grasp the spray nozzle handle in one hand and the foamer container in the other. Squeeze the spray nozzle handle to begin foaming. Continuous operation can be achieved by using the handle lock provided on the spray nozzle. Rinse by disconnecting the spray nozzle from the foaming lid assembly. To remove the foamer from the spray nozzle, simply grasp the quick connect on the spray nozzle in one hand and the foamer assembly in the other. Pull in opposite directions. (The outside collar around the quick connect will slide toward the spray nozzle, disengaging the foamer barrel.)

Cause: a. Clogged suction tube

Remedy: a. Clean or replace concentrate strainer


Cause: b. Metering tip orifice obstructed

Remedy: b. Rinse tip or replace: Do not attempt to clean - may alter size of orifice


Cause: c. Water pressure too low

Remedy: c. Minimum 25 PSI required


Cause: d. Mineral deposits in

Remedy: d. Back flush unit. Remove container, suction in barrel of foamer tube and metering tip. Put finger over barrel opening. Apply minimal water pressure through garden hose at nozzle of barrel to be flushed.

Cause: e. Clogged water inlet strainer (low water flow)

Remedy: e. Clean or replace strainer.


Problem 2. Weak foaming action


Cause: a. Clogged water inlet

Remedy: a. Clean or replace strainer


Cause: b. Water pressure too low

Remedy: b. Minimum 25 PSI required


Cause: c. Water temperature too

Remedy: c. Use lower temp water source. (Concentrate high flow decreases above 140º F water)


If above steps fail to produce good concentrate draw and/or foaming action, replace lid assembly.
