Complete assemblies include one lens cartridge consisting of four 0.06-inch untempered glass cover lenses, flow-control device, Snap-Tite aluminum quick-disconnect fitting, adjustable valve-connector body or pressure-demand regulator (with socket assembly), facepiece (medium) with dual-exhalation valves and lens housing, breathing tube, web-belt and air-hose connector.

Combination Pressure-Demand Breathing Apparatus

Features and Benefits

Carbon fiber escape cylinders for light weight and low profile
Traditional easy-to-use belt mounted regulator
Regulator conserves air for applications with limited air source

Principles of Operation

Operation of the Combination Pressure-Demand Breathing Apparatus is manual. It is an approved, rated five-minute escape device. The pressure demand air-line respirator phase is connected by an approved air-supply hose to a primary respirable air source; the worker breathes from this source with the valve of the egress (exit) cylinder of the device turned off until the user is ready to leave the working area. The user can leave, connected to the primary air source, or can open the egress cylinder valve and have approximately five minutes'; respiratory protection. When breathing from the air cylinder, the user can remain connected to the primary air supply and exit, or can disconnect from the air source for easier escape. If the primary air supply source should fail for any reason, the worker can switch to the egress cylinder by turning a valve and escape to a safe atmosphere.

Approvals and Standards

The Combination Pressure-Demand Breathing Apparatus is approved by the National Institute for Occupational Safety and Health (NIOSH) Approval TC-13F-143-when the device is supplied with respirable air from either the small escape cylinder or from a primary compressed-air source; the approval requires that when connected to a primary air source, an air inlet pressure between 65 and 85 psig must be maintained through an approved hose length of between 8 and 300 feet. The approval requires that the compressed-air cylinder be fully charged with air conforming to at least Grade D of Compressed Gas Association Commodity Specification for Air, G-7-1; use limited to temperatures above -25 degrees F.

Features and Benefits

Features air-purifying twin cartridges for use when airline is not available
Air-purifying mode can be used for entry or egress
Available in constant flow or pressure demand style

Principles of Operation

Inhaled air is drawn through either the air-line (when connected and air is flowing) or through the respirator cartridge (when air is not flowing). The air is then drawn into the facepiece (where it passes over the facepiece lens to minimize fogging) before it is taken into the lungs. Exhaled air then leaves the facepiece through an exhalation valve.

Approvals and Standards

MSA Constant Flow Duo-Twin Respirators are approved by the National Institute for Occupational Safety and Health (NIOSH) and the Mine Safety and Health Administration (MSHA) for use in atmospheres not immediately dangerous to life and health.* These respirators are approved with an inlet pressure range of 35 to 40 psig and with 8-300 ft. of MSA Air-Supply Hose.

Product Information

Provides respiratory protection for personnel who must work in atmospheres that are immediately dangerous to life and health (IDLH), such as in oil drilling and the manufacturing and handling of certain chemicals. Serves as both a long-duration work device and an escape device. Approved for respiratory protection for entry into, for extended periods of work in and for escape from IDLH atmospheres. If used for entry into IDLH atmospheres, the air-line must be connected before entry. The self-contained air supply is approved for escape only. Designed for good weight balance, the cylinder valve and pressure reducer are on the right side and the belt-mounted pressure demand regulator is positioned on the left side. The cylinder is connected to the regulator by a small length of neoprene air-supply hose, which rests on the wearers lower back, completely out of the way. One end of the hose attaches to the pressure regulator coming off the cylinder and the other to the top of a two-inlet manifold which leads directly to the regulator. The bottom inlet is equipped with a quick-disconnect device to attach the air-line to the unit, available with Snap-Tite, Foster, Hansen or Duff-Norton quick-disconnect. The cylinder valve is positioned on the front side of the cylinder so the wearer can simply tilt the cylinder and easily read the gauge. Also available is a Dual-Supply Hip-Air breathing apparatus. Dual-Supply increases mobility because workers do not need to remain tethered to a single air-supply hose throughout the work period. With dual-supply capability, users can connect from one pressurized continuous air source to another without losing continuity of airflow. When the first length of air-supply hose has reached its limit, the wearer simply plugs into a second approved air source and disconnects from the first. This technique is known as “leap-frogging” because it gives workers the ability to move from station to station without disrupting the supply of air.

PremAire® Cadet Supplied-Air Respirator

Features and Benefits

Simple design less cylinder for lightest weight and lowest cost
Firehawk MMR for ease of use and ergonomics
Shares common Ultra Elite facepiece with AirHawk SCBA
Available in standard nylon and nomex (high heat) versions

Principles of Operation

The PremAire Cadet Respirator is a pressure-demand device, meaning it delivers respirable air to the user "on demand." As such, it maintains a slight positive pressure of air inside the facepiece -- whether the wearer is inhaling or exhaling -- to prevent contaminants from entering the facepiece, should any slight face-to-facepiece seal leakage occur.
Because the unit is a pressure-demand device, it can be used with a large, compressed air cylinder or a bank of cylinders set up in cascade fashion. For longer-duration air supplies, the respirator also can be used with a compressor that delivers respirable air to the user within the NIOSH-approved pressure range.

Approvals and Standards

PremAire Cadet Respirators have received National Institute for Occupational Safety and Health (NIOSH) certification for use in atmospheres not immediately dangerous to life or health (Non-IDLH).*
Units are approved for use with an operating inlet pressure of 60-100 psig, and only when used with MSA Air-Supply Hose. PremAire Cadet Respirators require a source of compressed air conforming to at least Grade D Compressed Gas Association, Inc., Commodity Specification for Air, G-7.1.

*Not immediately dangerous to life or health is defined in 42 CFR Part 84 as any hazardous atmosphere which may produce physical discomfort immediately, chronic poisoning after repeated exposure, or acute adverse physiological symptoms after prolonged exposure.

Synergy® Bubble Hood Respirator

Features and Benefits

Lightweight with large PVC lens area
Double-bib design allows air to cool body garments
Large bib for extended protection
Communications port for integrating radio headsets

Principles of Operation

A constant-flow device, the Synergy Bubble Hood Respirator delivers a continuous flow of air into the hood from an external air source. Engineered for ease of use, the respirator has a quick-disconnect socket that directly connects the device to an air-supply hose and corresponding air source. This design eliminates the need for a control valve, which is typically used on other constant-flow respirators to control breathing air inlet pressure. With the Synergy Hood, inlet pressure is regulated at the air source.

To ensure a high level of protection, the respirator is designed to maintain a slight, positive pressure of air inside the hood, whether the user is inhaling or exhaling. This helps prevent contaminants from seeping into the hood assembly, while providing a cooling effect on the wearer's face.

The Synergy Bubble Hood also incorporates a unique "double-bib" design that helps to distribute air inside protective clothing for increased wearer comfort. An inner bib slips easily inside the protective garment while the second bib (worn outside the garment) is held secure with a one-inch nylon belt.

Approvals and Standards

The Synergy Bubble Hood Respirator has received National Institute for Occupational Safety and Health (NIOSH) certification for use in atmospheres not immediately dangerous to life or health (Non-IDLH).*

Units are approved for use with an operating inlet pressure of 12-49 psig, depending upon the length of air-supply hose used. And MSA Air-Supply Hose must be used with the Synergy Bubble Hood to maintain NIOSH approvals.

Synergy Bubble Hoods require a source of compressed air conforming to at least Grade D Compressed Gas Association, Inc., Commodity Specification for Air, G-7.

*NOTE: Not immediately dangerous to life or health is defined in 42 CFR Part 84 as any hazardous atmosphere which may produce physical discomfort immediately, chronic poisoning after repeated exposure, or acute adverse physiological symptoms after prolonged exposure.
