Foam sprayer with adapter and multiple pressure modes

A spray system including:

• a first fluid source configured to provide a first fluid at a first pressure;
• a second fluid source configured to provide a second fluid at a second pressure, wherein the second pressure is at least five times greater than the first pressure;
• and
• a foam sprayer including:
• a body defining a channel;
• a nozzle attached to the body and configured to emit foam;
• a connector attached to the body, the connector configured to releasably connect to the second fluid source to allow the second fluid from the second fluid source to flow into the channel of the body;
• and
• an adapter configured to releasably attach to the connector when the connector is not attached to the second fluid source, the adapter configured to releasably attach to the first fluid source and direct the first fluid from the first fluid source through the connector and into the channel of the body,
• wherein the foam sprayer is configured to operate in a low-pressure mode to generate foam from the first fluid, and operate in a high-pressure mode to generate foam from the second fluid.

A method of emitting foam from a sprayer, the method comprising:

• attaching a first fluid source or a second fluid source to the sprayer, the sprayer including:
• a body defining a channel;
• a nozzle configured to emit foam;
• a connector attached to the body;
• and
• an adapter configured to releasably attach to the connector and to the first fluid source to allow a first fluid at a first pressure from the first fluid source to flow into the channel of the body, the connector configured to releasably connect the body to the second fluid source when the adapter is not connected to the connector, wherein the second fluid source provides a second fluid at a second pressure that is greater than the first pressure;
• selecting a low-pressure mode or a high-pressure mode of the sprayer using a mode selection device;
• and
• emitting foam from the sprayer, wherein the sprayer is configured to emit foam from the first fluid when the foam sprayer is in the low-pressure mode, and wherein the foam sprayer is configured to emit foam from the second fluid when the foam sprayer is in the high-pressure mode.
