A simple and powerful foam generator from a fire extinguisher

Homemade foam generator for car washing

Cheap home mini car washes have an insufficiently effective foam nozzle. As a result, even good non-contact foam copes poorly with dirt. You can improve the quality of cleaning your car by using a homemade foam generator. It copes with stubborn dirt, which can later be easily washed off with a mini-wash.

Materials:


  • body from an old powder fire extinguisher with neck and lid;
  • 1/2 inch steel tube;
  • a piece of rubber from the chamber for the seal;
  • garden hose;
  • garden hose nozzle;
  • ball valve 1/2 inch;
  • quick-release adapter fitting to compressor M1/2 inches;
  • fumlenta.

The foam generator is made using a meringue powder fire extinguisher or an old hand-held steel spray gun. You can use another metal container of 8-10 liters. It must be equipped with a neck with a threaded cap and a rubber seal.

A hole is made at the top end of the container for a 15 mm tube. It will be used to release foam. A short piece of pipe 7-10 cm is welded into it. A thread is cut on it to secure the adapter to the garden hose.

A hole for the tube is drilled on the side of the bottom of the cylinder. It will be used to supply air. A plugged pipe with side holes is inserted into it.

10 holes drilled in a row with a 2 mm drill are enough. The tube is welded so that they look up. Next, a thread is cut on it to secure the ball valve. The compressor hose fitting is screwed onto it. All threads are pre-sealed with fumlente or another method.

How to use


Fill the foam generator about halfway with water. Car shampoo is added to it for contactless washing. The tank is closed with a lid. A compressor is connected to the lower adapter.

After turning on the compressor and opening the ball valve, the supplied air mixes the water, creating foam.

It rises to the top of the tank and, after it is filled, moves along the garden hose, splashing out onto the car.

A foam generator of this design works much better than many standard attachments for a mini-wash. It makes a thick foam, which, when using normal shampoo, allows you to wash even a very dirty car with minimal time and effort.

At the end, we wash everything off with water from a high-pressure washer or from a garden hose under normal pressure.

    Simple, but not simple. Where can I get a compressor? And so very good. good idea, I’ll buy a compressor and make one for myself.

    If you insert a mesh or any other filler into the air supply tube to cut the air flow, you will get thicker foam at the output and, accordingly, lower consumption.

    Why such a bother, buy a foam concentrate for Karcher

      Did you end up with a foam generator or just a so-so idea?

    good idea! What pressure is set on the compressor?
