The Nilfisk foam gun is a high quality foam sprayer. The foam gun contains a foam cup of 1L, to which you can easily add one of our cleaning agents. It creates a thick stable foam during washing. We recommend setting the water temperature on your high-pressure cleaner to a maximum of 60 degrees during use. The foam gun contains an adjustment knob that regulates the consumption of the added detergent. In addition, the spray distance is adjustable from 1m (wide jet) to 10m (narrow jet).
