Abstract
A coupling for use with a blower unit for detecting leaks in a structure, wherein the coupling is constructed and arranged to attach to a surface of the structure defining an opening and to the blower unit, and to allow air flow through the coupling when the blower unit is attached to the coupling and to prevent air flow through the coupling when the blower unit is not attached to the coupling, and wherein the coupling further includes a pressure port defined within a surface of the coupling constructed and arranged to accommodate at least one of a differential pressure gauge fitting or a tube.
Claims36
A product comprising:
- a coupling constructed and arranged for attachment to a blower unit for detecting leaks in a structure and for attachment to a surface of the structure defining an opening, and to allow air flow through the coupling when the blower unit is attached to the coupling and to prevent air flow through the coupling when the blower unit is not attached to the coupling, and wherein the coupling further includes a pressure port defined within a surface of the coupling constructed and arranged to accommodate at least one of a differential pressure gauge fitting or tube.
A product comprising:
- a blower unit constructed and arranged to attach to an exterior surface of a structure to pressurize an interior of the structure for leak testing of the structure, wherein the blower unit comprises an impeller unit and a conduit attached to the impeller unit, wherein the blower unit is constructed and arranged to direct an air flow from outside of the structure through the conduit and into the interior of the structure to pressurize the interior of the structure, the blower unit comprising a housing and a differential pressure gauge attached to the housing.
A method comprising:
- providing an opening defined within a structure;
- operatively attaching a coupling to an exterior surface of the structure defining the opening so that the coupling is in fluid communication with the opening, wherein the coupling is constructed and arranged to be in a closed position to prevent air flow through the opening or an open position to allow air flow through the opening;
- attaching a blower unit to the coupling when the coupling is in an open position, the blower unit comprising a housing and a differential pressure gauge attached to the housing;
- flowing air into an interior of the structure to pressurize the interior of the structure using the blower unit;
- spraying a solution having a surface tension to produce bubbles when air is blown onto it;
- and
- determining a location of a leak where bubbles are present.
