Abstract
A self-contained respiratory protection system is disclosed. The system includes a center module attachable to one or more cylinders of air, gas or oxygen. A plurality of filters is mountable on the center module. A blower motor also may be mounted on the center module. A hose attaches to a cylinder to provide air to an operator or draws filtered air via the filters on the center module. A first stage regulator converts the air in the cylinder to breathable air for the operator. A second stage regulator transitions between filter mode and supplied air. The system may fit within a backpack.
Claims22
A breathing apparatus comprising:
- one or more contained air cylinders connected to a supply manifold;
- a contained air supply hose connected to the supply manifold;
- one or more air filters connected to a filtered air manifold;
- a blower motor connected to the filtered air manifold;
- a filtered air supply hose connected to the filtered air manifold;
- and
- an air supply assembly connected to both the contained air supply hose and the filtered air supply hose for delivery of pressurized contained air, filtered air, or powered filtered air.
A modular breathing apparatus comprising:
- a self-contained air module comprising one or more pressurized cylinders, a pressurized air supply hose, and a manifold connected to the one or more cylinders and the pressurized air supply hose;
- a filtered air module comprising one or more air filtration cartridges, a filtered air supply hose and a filtered air manifold connected to the one or more filtration cartridges and the filtered air supply hose;
- a powered air module comprising a blower motor connected to the filtered air manifold;
- and
- an air supply assembly for delivery of pressurized air and filtered air to a user comprising a regulator connected to the pressurized air supply hose and a filtered air supply connection.
A modular breathing apparatus comprising:
- a manifold having one or more cylinder connections, a manifold discharge, and one or more manifold ports;
- a first pressurized air delivery system comprising;
- a high pressure regulator in fluid communication with the manifold discharge;
- a low pressure supply hose in fluid communication with the high pressure regulator,
- a second stage regulator in fluid communication with the low pressure supply hose;
- a second pressurized air delivery system in fluid communication with the manifold discharge and the high pressure regulator of the first pressurized air delivery system, the second pressurized air delivery system comprising a pressure hose and one or more quick connection fitting at the terminal end of the pressure hose.
A method for providing air supply comprising:
- providing self-contained air through a pressurized air manifold and pressurized air supply hose;
- providing filtered air through a filtered air manifold and filtered air supply hose;
- providing powered filtered air through a blower motor connected to the filtered air supply manifold;
- and
- and switching between pressurized air and filtered air or powered filtered air wherein the switching is on demand by activation of a regulator upon reduced filtered air or powered filtered air supply.
A method of providing a modular breathing apparatus, comprising:
- providing a pressurized air manifold with one or more sealable supply connections and one or more pressurized cylinders connected to the sealable connections, wherein the connection is sealed with a cap when a cylinder is not connected thereto;
- providing a filtered air manifold with one or more sealable filter connections and one or more air filtration cartridge connected to the sealable filter connections, wherein the connection is sealed with a cap when a filtration cartridge is not connected thereto;
- providing a blower motor connected to the air manifold at one of the sealable filter connections;
- connecting a sealable mask to the pressurized air manifold wherein the connection includes one or more regulators;
- connecting the sealable mask to the filtered air manifold;
- and
- automatically switching between pressurized air supplied from the pressurized air manifold and the filtered air supplied from the filtered air manifold.
