Foam Lance Venturi Pro
Venturi Pro is the new Foam Lance from Alchimy 7. Still available with 2 tanks for use with a pre-wash product and a finishing wax.
from €100 of purchase.
The Foam Lance Venturi Pro is a foam cannon compatible with pressure washers, manufactured by the French brand Alchimy 7, and ideal for the pre-wash stage. Using this Foam Lance Venturi Pro with the appropriate products (foaming agent & shampoo or 2-in-1) produces an intense, thick foam that removes the heaviest dirt from your paintwork.
The pre-wash stage is ideal for minimizing the risk of micro-scratches. Indeed, removing the heaviest dirt before a traditional two-bucket wash reduces the risk of defects caused by your wash mitt or sponge coming into contact with the paintwork.
The Venturi Pro, Alchimy 7 is equipped with:
- 1 connector of your choice for a pressure washer (to be selected from the drop-down menu)
- 2 reinforced 1000ml tanks with double graduation (markings every 50ml)
- 2 tank caps
- 1 AISI 316 L stainless steel connector tube
- 1 suction filter
- 1 information & user guide
- 1 additional 1.40mm nozzle
MAKE SURE TO SELECT THE CORRECT ADAPTER FOR YOUR PRESSURE WASHER (See product sheet "adapters").
What is the additional 1.40mm nozzle for?
The 1.40mm nozzle allows the Venturi Pro A7 to be used with pressure washers with very high flow rates and very high pressure. If the pressure washer does not run continuously (a "pumping" phenomenon = the pressure washer runs for 2 seconds then cuts off and restarts 2 seconds later, etc.), this means the pressure washer is going into safety mode and the original nozzle is too small. In this case, simply replace the original nozzle (1.25mm) with the 1.40mm nozzle. A simple flat-head screwdriver is sufficient to replace the nozzle.

** Alchimy7 - Official Brilliance Supplier - The French Excellence of Detailing **
Founded by Arnaud Prayer, Alchimy7 is a pioneering French brand in the field of automotive detailing. Created in 2009, Alchimy7 was born from one man's passion for car care and his relentless pursuit of perfection. Faced with a lack of quality products on the French market, he decided to develop his own range based on extremely rigorous specifications. Today, Alchimy7 offers a wide range of products, from cleaners to high-quality microfibers, as well as surface protections, to meet the needs of both demanding enthusiasts and professionals. Every product is developed, tested and manufactured in France, ensuring exceptional performance and quality.
How do you use the Alchimy7 Venturi Pro Foam Cannon?
- Foam density adjustment (Clockwise = more foam. Counterclockwise = less foam. A visual guide is engraved on the adjustment knob. This setting controls chemical suction. Higher product suction = denser foam = faster reservoir depletion.)
- 360° rotating spray pattern collar. Allows quick switching between horizontal and vertical foam fan patterns. Features 2 detents to lock in the desired orientation (Horizontal or Vertical).
- Spray width adjustment collar. Operates with a 1/4 turn to adjust the blade gap, allowing fast and easy adjustment of the foam fan width.
