  • More details

The Drum Mount HV Foamer is a high volume foam applicator that straps directly to a drum or tote of chemical concentrate.

This venturi injection system uses standard city water pressure (35 - 125 PSI) to draw and blend chemical concentrate directly from the drum into the water stream to create an accurately diluted solution. A high volume of rich, clinging foam is 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 on to any surface at distances up to 15 feet (25 feet with optional zero degree nozzle).

It requires 4-16 CFM compressed air @113-453psi pressure, 15 litres p/m @ 40 psi water pressure.

It includes 25.5 x 15m discharge hose, S. Steel mounting bracket, complete foaming gun & 21 colour coded metering tips. High Volume Output, Covers up to 45m2 in one minute  15 feet / 4.5m usable Foamer Throw.

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 ON THE SLIDESHOW)

If you are connecting to a potable water supply follow all local codes for backflow prevention.
1. Mount the foamer to the drum.
2. Once metering tip is installed attach the pick-up tube and feed it through the bung hole.
3. Connect the discharge hose.
4. Connect water supply, to prevent blocking the small water jets in the foamer body flush any new plumbing of debris
before connecting. If water piping is older and has known contaminants install a filter.
5. Connect air supply, if air line is older and has known contaminants install a filter.

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.

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 FOAM
1. Make final metering tip adjustments based on application results.
2. With wand in hand open the water ball valve, and the air ball valve.
3. Open the discharge ball valve.
Wait a few seconds and observe foam consistency.
Use the least amount of air needed to achieve good foam quality to prevent water pressure fluctuations
from affecting performance. Air pressure must be kept lower than water pressure.
To adjust the foam consistency pull out on the air regulator knob, turn slightly clockwise for dryer foam and
counterclockwise for wetter foam. Wait a few seconds to see each adjustment.
Medium wet foam will give the best cleaning results! Dry foam will NOT clean as well!
You may also have to try different sized metering tips and air settings until foam consistency and cleaning
results are acceptable. Once this is set and desired foam consistency is achieved push lock the knob on
the air regulator. You are ready to start application.
4. When foaming is completed, close the discharge ball valve, return to the unit and close the water and air ball
valves. Briefly re-open the discharge ball valve to relieve pressure in the hose.
5. Rinse before the foam dries.
