2 ESAB AIR PRSL PARTICLE FILTER
2.1 Application
The PRSL particle filter protects against the majority of particles: hard particles,
fluid-aerosols, bacteria, viruses and enzymes. When used to filter radioactive dust,
microorganisms and enzymes, the PRSL particle filter should be disposed of after use.
2.2 Storage
Store the PRSL particle filters in a dry, clean area, between 0°C and +40°C (32–104°F)
with relative humidity less than 75%RH.
Protect the particle filter from dust, particles and other contamination when stored.
2.3 Product life
The lifecycle of the PRSL particle filter depends on the conditions of the work area and the
concentrations of particles in the air, as well as the length of operating time.
NOTE!
Never use second-hand particle filters. Never attempt to clean a particle filter.
2.4 Usage
Do not use the ESAB PAPR System with PRSL particle filter in confined spaces lacking
ventilation.
Do not use the ESAB Air respiratory system in areas were explosions might occur.
The oxygen level in the working area must be a minimum of 19.5% and the temperature
must be between 0–40°C (32–104°F).
The composition of the fumes generated during the welding process must be known.
Before usage it should be ascertained whether the ESAB particle filter offers suitable
protection from the hazard.
Particle filters cannot be used to filter organic fumes and vapors. For such purpose, a
combination filter must be used.
The PRSL particle filter must be used with an ESAB Air blower unit. Use only original,
sealed particle filters produced by Universal PPE and Welding Accessories Limited. Do not
use PRSL particle filters with damaged sealing gasket or any visible damage to the casing.
The ESAB Air blower unit sounds the alarm for 4 seconds after power-on. If the alarm
sounds during operation, leave the working area immediately and get into a
non-contaminated environment.
Warranty replacement claims will be approved only if the unit has been regularly cleaned,
inspected and the PRSL particle filter replaced at least every 2 weeks.
2.5 Remove and replace the particle filter
To remove the particle filter, unclip the particle filter cover and pull off the particle filter with a
slight twisting action.
To replace the particle filter, check it for any damage, place the particle filter over the air inlet
cover and push the particle filter onto the seal of the blower unit. Close the particle filter
cover.
