PRODUCT OVERVIEW
Foam proportioning.
Part of your system.
The variable inline inductor provides selector-controlled foam-concentrate induction. Its technical specification lists 0%, 1%, 3% and 6% settings, allowing the proportion to be matched to the selected concentrate and application.
Water passing through the Venturi throat creates the pressure differential that draws concentrate from an external container. The selector regulates concentrate induction while the connected branch pipe, monitor or generator receives the mixed foam solution.
The aluminium alloy assembly is compact and portable, with quick coupling connections. Select the model’s rated water flow independently of its foam proportion setting; the selector controls concentrate proportion.
Aluminium construction
The catalogue specifies an aluminium alloy body with powder-coated or natural anodized finish options.
Deployment flexibility
Venturi operation requires no external power and supports compatible mobile or fixed foam-system arrangements.

WORKING PRINCIPLE
From flowing water
to proportioned solution.
Venturi induction uses the water supply to draw concentrate into the flowing stream.
Water enters the Venturi
Pressurised water passes through a narrowed throat. Its velocity increases and the pressure decreases.
Concentrate is drawn in
The pressure differential draws foam concentrate from the external container through the pickup hose at the selected proportion.
Foam solution is delivered
Water and concentrate mix inside the inductor. The solution passes to a compatible foam branch pipe, monitor or generator for discharge.
OPERATION
Connect. Check.
Flush after use.
Product catalogue guidance to use with the selected equipment and the facility’s operating procedure.
- 01
Connect the equipment
Connect the inlet to the water supply and the outlet to the selected foam branch pipe, monitor or generator. Secure the pickup hose to the concentrate supply.
- 02
Establish the water supply
Open the supply gradually to achieve the required operating pressure for the selected model.
- 03
Check concentrate induction
Keep the pickup inlet immersed in the concentrate and verify that concentrate is being drawn into the water stream.
- 04
Flush after operation
Flush the inductor and pickup hose thoroughly with clean water to remove residual foam concentrate.

INSPECTION & MAINTENANCE
Keep the passage clear.
Check the proportion.
After-use care, monthly inspection and annual maintenance from the product catalogue. Include these in the equipment’s maintenance programme.
01After every use
- Flush the inductor and pickup hose with clean water and remove foam concentrate residue.
- Dry the equipment before storage.
- Inspect the couplings, seals and pickup hose.
02Monthly inspection
- Check for corrosion and physical damage.
- Keep the Venturi passage clean and unobstructed.
- Inspect the pickup hose, strainer and connections.
- Check water flow and concentrate induction performance.
03Annual maintenance
- Carry out a complete operational performance test.
- Replace worn seals and gaskets where required.
- Inspect internal passages for scale and blockage.
- Verify proportioning accuracy against the selected model’s manufacturer specifications.
