A little science popularization about car beauty care – have you heard of a foam sprayer?
PA pot is the abbreviation of high pressure foam spray pot in the field of automobile beauty, which is mainly used for pre-washing vehicles with high pressure washing machines, and through the principle of physical foaming to produce dense foam to soften dirt.
Core definitions and how they work
PA pot full name is Pressure-Activated Foam Applicator (Pressure Activated Foam Applicator), is a professional car wash tool that does not rely on electricity, only driven by water.
How it works: Using the negative pressure generated when high-pressure water flows through the internal Venturi tube, the car wash liquid is automatically inhaled and mixed with the air.
Bubble effect: The mixed liquid is filtered by a foam net, which ejects a fine, snowy foam like cream, which can hang on the paint surface for a long time.
Core role: "pre-wash" before formal polishing allows the dirt to loose and be carried away with the foam flow, greatly reducing the sun-line damage caused by direct polishing on the paint surface.
The difference between pa pot and ordinary foam pot
There are significant differences between the PA pot and the common hand pressure or air pump foam pot in the driving mode and effect, and the user can choose according to the needs.
How it is driven:
PA pot: must be connected to the high-pressure car washing machine, relying on water pressure drive, water pressure has certain requirements (usually recommended above 100bar household machine).
Regular foam pot: generates air pressure by a manual blowing or electric pump and is used independently without the need for a high pressure water source.
Bubble quality:
PA pot: thick foam, covering a comprehensive, suitable for deep cleaning of the whole car, but the consumption of car wash liquid is relatively large.
Ordinary foam pot: The foam is relatively thin, has low water content and dries quickly, is suitable for local cleaning or small vehicles, and the concentration of car wash liquid can be controlled and saved.
Applicable scenarios:
PA pot: suitable for the pursuit of efficient, comprehensive car washing and high-pressure cleaning equipment users.
Regular foam pot: suitable for users who do not have high pressure equipment, value for money or who need simple cleaning.
Use and maintenance and purchasing references
The correct use and maintenance can extend the life of the PA pot and ensure the foaming effect, and pay attention to the compatibility maintenance points when purchasing:
Cleaning residue: After use, remove the kettle body and spray water to flush the residual foam in the foam cavity to prevent the filter being blocked.
Storage Note: drain the liquid inside the empty kettle when storage, to avoid corrosion of the sealing ring by the car wash liquid, and the spray cores and foam nets need to be properly handled.
Structural adjustment: The top knob can adjust the fan size, some of the vessels have a liquid absorption adjustment function, and screwing the end clockwise usually results in the largest bubble effect.
Selection Recommendation: Choose copper nozzle construction as a priority for corrosion resistance, and verify that the core specifications are suitable for existing car washers (e.g. 1.0mm or 1.25mm aperture).
