Comfo® Twin-Cartridge Respirators
Protection against a variety of respiratory hazards
Because every life has a purpose...
MSA Comfo Twin-Cartridge Respirators provide protection against
a variety of respiratory hazards. The respirators use chemical
cartridges, aerosol lters, or a combination of the two, to remove
specic contaminants from the inhaled air. The cartridges are
interchangeable among all MSA Comfo Twin-Cartridge Respirators
and are constructed of high-strength metal.
The respirators are available in a half-mask facepiece version
(Comfo Classic®) and two full-facepiece styles (Ultra-Twin® and
Ultra Elite®). In addition, with the Twin-Cartridge Adapter, the
user can convert any demand-style Ultravue® or Ultra Elite
Full-Facepiece into a twin-cartridge respirator.
All MSA Comfo Twin-Cartridge Facepieces are available in hycar
rubber or silicone, which has a unique sealing surface designed
to reduce facepiece slippage. All are formulated to maximize
comfort and minimize the possibility of skin irritation, yet are
resistant to chemicals and facial oils. They all come in small,
medium and large sizes.
Parts can be quickly connected and
disassembled for ease of maintenance.
Applications
Applications for MSA Comfo Twin-Cartridge Respirators include
welding, smelting, construction and hazardous waste remediation,
as well as others in the chemical, oil and gas, marine, and pulp and
paper industries. These comfortable respirators are ideal for both
intermittent and extended exposure situations.
Limitations
As an air-purifying device, all MSA twin-cartridge respirators must
not be used in atmospheres containing less than 19.5 percent
oxygen, or in atmospheres immediately dangerous to life and
health (IDLH).
Twin-cartridge respirators must not be worn for protection against
gases or vapors with poor warning properties.
Twin-cartridge respirators must not be used in atmospheres
containing more than 100 times the exposure limit for the
contaminant present.
