AP OMEGA BREATHING APPARATUS
AP OMEGA is an open circuit, self-contained compressed air-breathing apparatus. The apparatus is designed for professional fire-fighters, factory personnel and emergency response teams at enterprises with hazardous production facilities.
The apparatus enables safe and comfortable operation in smoke-filled and gas-polluted environment when it is impossible to use filtering gas masks. It can also be used when there is a threat of emissions of unpredictable concentration chemistry that can be dangerous for a man for breathing and visual organs.
Backplate
The light-weight backplate is made of composite materials and intended for arranging pneumatics and hoses.
Harness
The harness is available with flame-retardant padded straps as a standard version.
Optionally, for better wearer’s comfort, AP OMEGA can be equipped with lumber pad. AP OMEGA can be configured for use with one cylinder or twin cylinders. Single cylinder apparatus can be easily altered by a wearer (no tools required) to twin cylinder apparatus. A kit is available for converting single cylinder apparatus to twin cylinders apparatus.
Reducer
The reducer is a simple, self-regulating, spring-and-piston device that requires no adjustment. It has a pressure relief valve that protects the medium pressure system from overpressure.
Gauge and whistle
A high-pressure hose from the reducer inlet connects air at the cylinder pressure to a warning whistle and pressure gauge mounted on the OMEGA shoulder strap. The warning whistle sounds when pressure in the cylinder falls to 55 5 bar. In case of need wearer can easily adjust whistle actuating pressure.
Demand valves
The demand valve operates in conjunction with the facemask’s spring loaded exhale valve to maintain a positive pressure within the facemask.
OMEGA breathing apparatus has two different types of the demand valves:
- Demand valve AP-2000 (middle size) screwed into the facemask. It has a lever-diaphragm mechanism, which responds to pressure changes in the facemask to regulate the flow of air to the mask thus ensuring that pressure in the mask remains safely above the ambient pressure.
- Demand valve Delta (small size) screwed or plugged into facemask. It has a servo-assisted tilting diaphragm mechanism, which responds to pressure changes in the facemask to regulate the flow of air to the mask thus ensuring that pressure in the mask remains safely above the ambient pressure.
The demand valves are activated when wearer takes the first breath.
Facemask
OMEGA is used with:
- Neoprene Delta full facemask with the rubber head harness
- Neoprene PM-2000 full facemask with rubber head harness
Attachments
The following options are available:
- Hose attachment with male and female connectors joins pneumatic system of the breathing apparatus with a gas-tight chemical suit.
- Rescue mask attachment permits the wearer to supply a rescue mask from own air cylinder.
- Airline attachment permits AP OMEGA to be used with an airline. The cylinder provides emergency backup.
- Quick fill device permits to fill the cylinder(s) with compressed air from transporting cylinders.
- Atmospheric valve permits the wearer to breathe with ambient air while keeping the facemask on.
