The design and construction of the filter self-rescuer up to the
present day is the fruit of the extensive experience gained through
MSA’s long-standing association with mine rescue worldwide.
Design & Functionality
The CO-filter is an oxidation catalyst which
converts the carbon monoxide to carbon
dioxide. The catalytic reaction is exothermic –
an integral heat exchanger reduces the
inhalation air temperature to a tolerable
level. The expired air is passed back through
the heat exchanger and a spring-loaded
exhalation valve into the ambient air.
Filter Self-Rescuer W65-2/W65 - Standard version
The W 65-2/W 65 is a standard Filter Self-Rescuer, available in
shoulder carrying mode (W 65-2) or with integral belt loop (W65/W
65-2 BL). The CO-filter uses the catalyst Hopcalite and a drying agent
to retain inhalation air moisture.
Filter Self-Rescuer W95 - Version for extended escape routes
The W95 is a Filter Self-Rescuer designed for extended escape routes,
available in shoulder carrying mode (W95) or with integral belt loop
(W 95 BL). The CO-filter uses a noble metal catalyst and a Hopcalite
pre-filter. This unique combination provides high breathing comfort
together with reduced inhalation resistance and temperature. It has
a service life of more than 4 hours.
Training devices - Simple & economical training
Filter Self-Rescuer trainer versions provide simple and economical user
training in a non-contaminated atmosphere. After use, they can easily be
cleaned, assembled, and used again. For clear identification they are stored
in blue containers.
The standard model W65-TR simulates size, weight, donning procedure and
The new training device W 95-TR in addition provides inhalation air at temperatures
of up to 55 °C for approx. 15 minutes. This permits the trainees to
familiarize themselves with the hot dry air typical under emergency conditions.
The W95-Trainer is delivered as a “cold air” trainer with an air restrictor
to simulate breathing resistance and weight. For “hot air” training the restrictor
is simply replaced by the single-use hot air cartridge.
