Injector Kits & Foaming Tools

Injector kits are fantastic tools that allow you to introduce chemicals, detergents, or soaps into your pressure washer's water stream. It's a simple but brilliant system! Typically, a chemical injector works on the venturi principle. As high-pressure water flows through the injector body, it creates a vacuum that siphons the chemical from a container through a small hose and into the water flow. This mix is then delivered through your hose and out of the spray nozzle.

These kits are incredibly versatile and are commonly used for applying cleaning solutions for tasks like washing vehicles, cleaning building exteriors, or sanitising agricultural sheds. They are essential for any job that requires a chemical application alongside high-pressure water. For efficient and controlled application, pairing your injector with the right foaming tools is key. You can explore a wide range of compatible accessories, including lances and nozzles, in our Nozzles & Accessories collection to get the perfect setup for your cleaning needs.

Using dedicated foaming tools is a game-changer for any serious cleaning job! The biggest benefit is extended contact time. When you apply a chemical as a thick, rich foam, it clings to surfaces - especially vertical ones - far longer than a liquid spray. This gives the cleaning agent more time to break down dirt, grease, and grime, which means less scrubbing for you and a much deeper clean. It’s all about working smarter, not harder!

Foam also provides excellent visual confirmation of where you've applied the product, ensuring complete coverage and preventing wasteful overuse. This controlled application is not only more efficient but also safer, as it minimises aerosolisation and chemical drift. Whether you're in automotive detailing, food processing sanitation, or heavy equipment wash-downs, a quality foam cannon or foamer attachment will give you a superior, professional-grade result.

Choosing the right injector kits is super important for getting the best performance from your pressure washer! It all comes down to matching the kit to your machine's specs. The two key things you need to know are your pressure washer's flow rate (litres per minute or LPM) and pressure rating (PSI). Injector kits are rated for specific flow and pressure ranges, and using an incorrect one can lead to poor chemical draw or damage to your equipment.

Think about the job too. For heavy-duty degreasing on industrial equipment, you might need a high-draw injector. For more delicate jobs like vehicle washing, a standard chemical injector will do the trick perfectly. Always check the product description to ensure compatibility with your pressure washer’s specifications. Making the right choice ensures your chemical dosing is accurate and your cleaning is as efficient as possible.

After every single use of your injector kits and foaming tools, the most important step is to flush the system thoroughly with clean water. This is a non-negotiable! Run fresh water through the chemical siphon hose and the foamer for a couple of minutes. This simple action prevents chemical residue from drying inside, which can cause blockages, corrosion, or damage to delicate internal components like o-rings and seals.

Periodically, you should inspect the filter on your chemical suction tube for any blockages and give it a good clean. For foaming tools, especially foam cannons, it's a great idea to occasionally disassemble the nozzle and soak the internal mesh screen in a descaling solution or vinegar to dissolve any hard water or soap scum build-up. A well-maintained kit means reliable performance and consistent foaming action every time you fire up your machine
