The SEALTECH 43O-AL makes ingenious use of a very simple.

Fact: air flowing through an opening covered with a soapy water (“surfactant”) solution produces a bubble precisely at the opening. The system draws outside air into the RV via the roof vent, where it is dispersed, creating a positive interior pressure. This pressure difference causes air to flow outward through any outer skin faults. The application of a soapy water solution to selected areas of the outer skin results in a very visible bubble exactly over each leak.

As each RV design has different characteristics, we have incorporated an impeller RPM controller to permit control of airflow and pressure. An accurate, easily read differential pressure gauge is also included. Power draw is 4.9 amps.

This system is extremely simple to use. Owners have been able to assign leak diagnosis and recording to inexpensive junior staff, freeing up more experienced technicians for leak repair and other tasks requiring greater expertise.

Because of the large surface areas involved, and the numerous routes for air to escape a typical RV, the SEALTECH 43O-AL is engineered and built to produce high air flow, but only to safe nominal pressures. All components are of premium quality, to provide many years of safe, trouble free operation. The product carries a two-year full parts and labor warranty.
