The Sealtech 430-AL – How It Works

The SEALTECH 43O-AL series 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 suspicious areas of the outer skin results in a very visible bubble exactly over each fault.

Each RV design has different characteristics so 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, SEALTECH’s 43O-AL series 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. Every Sealtech unit comes with a full one year parts and labor warranty.
