Foam Blaster is a compression sprayer designed to enhance foams. It holds 8Ltrs of liquid. When full it's enough to pre-wash/foam 3 cars. Because the Foam Blaster applies a more concentrated foam the cleaning power is better than traditional foam lance systems. This is because traditional foam systems apply the foam at a final dilution of up to 1:300 our Foam blaster applies foam at a dilution of 1:15 up to 1:25 which you have full control over when filling your pump up. There is an environmental benefit that you use less water which is good news if you're on a water meter. In addition you will use the same or less concentrate, so its the same cost per car clean too. These are high quality fully repairable compression sprayers that we are very proud of.
