Menu Copyright © 2005 by The SEA Group FILTERS 1: Particle Filters Skip to Half Masks

Menu Copyright © 2005 by The SEA Group Two main types Mechanical impact (such as Sundström) A fine mesh barrier that lets air through but not particles Electrostatic Electric charged filter material acts like a “glue”, making particles stick to filter surface

Menu Copyright © 2005 by The SEA Group The 1 st problem with ELECTROSTATIC: It’s like throwing tacks at a magnet: Throw them SLOWLY, and the magnet catches them all

Menu Copyright © 2005 by The SEA Group …but throw them QUICKLY, and some will get through The 1 st problem with ELECTROSTATIC:

Menu Copyright © 2005 by The SEA Group The 1 st problem with ELECTROSTATIC: REDUCTION in some filters up to

Menu Copyright © 2005 by The SEA Group So how can electrostatic filters pass standards tests?

Menu Copyright © 2005 by The SEA Group So how can electrostatic filters pass standards tests? Because standards tests are done at 95 litres/minute… …while people often breathe at litres/minute!

Menu Copyright © 2005 by The SEA Group The 2 nd problem with ELECTROSTATIC: Moisture | Humidity | Oil mist

Menu Copyright © 2005 by The SEA Group The 2 nd problem with ELECTROSTATIC: Oil mist is EVERYWHERE!

Menu Copyright © 2005 by The SEA Group Mechanical Impact Not affected by air speed Not significantly affected by humidity or oil mist Only keeps on collecting particles Gets “better” the more particles are caught Replace when hard to breathe through

Menu Copyright © 2005 by The SEA Group Sundström particle filter P100 Dry particles (dust) Wet particles (aerosols, sprays) Smoke and fumes Fibres Mould Bacteria and viruses

Menu Copyright © 2005 by The SEA Group When to replace If there is any damage to the filter or When the filter feels hard to breathe through or After 4-6 weeks’ use

Menu Copyright © 2005 by The SEA Group Comparison Other brands: Every week* Sundström: Every 4-6 weeks Particle filter replacement *) Average filter life 40 hours, as stated by manufacturer

Menu Copyright © 2005 by The SEA Group FILTERS 2: Gas Filters

Menu Copyright © 2005 by The SEA Group Adsorption efficiency of gas filtres NOT affected by air flow rate

Menu Copyright © 2005 by The SEA Group Pulsating air flow MAY affect life span (still 100% adsorption, but time before breakthrough may be shortened)

Menu Copyright © 2005 by The SEA Group Colour coding Organic vapour AmmoniaAcid gas - Inorganic Gas Particles

Menu Copyright © 2005 by The SEA Group Combination filters If you need protection against BOTH particles and gas: A: Use a special combination filter B: Make a combination filter by pressing a particle filter onto the front of a gas filter

Menu Copyright © 2005 by The SEA Group To separate a combination filter Insert a coin or similar between the rim of the particle filter and the lug on the side of the gas filter Twist apart

Menu Copyright © 2005 by The SEA Group When to replace According to a replacement schedule Replacement of gas filters depends on: Type of contaminant Concentration of contaminant Temperature and Humidity Workload

Menu Copyright © 2005 by The SEA Group FILTERS: 3: Pre-filters

Menu Copyright © 2005 by The SEA Group Pre-filters… Should ALWAYS be used Protect the main filter Are low cost items Should be replaced AT LEAST once a day

Menu Copyright © 2005 by The SEA Group Sundström half mask SR100 Skip to Fitting

Menu Copyright © 2005 by The SEA Group Features Mask body and filter holder are made of a SINGLE PIECE of silicone material

Menu Copyright © 2005 by The SEA Group Features Large surface area of the filter holder means a lighter filter and lower breathing resistance

Menu Copyright © 2005 by The SEA Group Features Filter holder situated very low on the mask. This means much better weight balance on the face

Menu Copyright © 2005 by The SEA Group Features Continuous one-piece head harness works like shock absorbers on a car: weight and tension are evenly distributed

Menu Copyright © 2005 by The SEA Group Features Head harness is easily removed for cleaning or replacement

Menu Copyright © 2005 by The SEA Group Features Specially designed valve cups with internal deflectors to eliminate clogging of the valve by spray or aerosols

Menu Copyright © 2005 by The SEA Group Features Exhalation valves have a 90 degree flange to stabilize movement and ensure rapid return to closed position

Menu Copyright © 2005 by The SEA Group Features Sealing surfaces (rims) are sandblasted (matted) for slip-free seal. A deep chin cup ensures secure fit and good balance

Menu Copyright © 2005 by The SEA Group Features The mask if fitted with a water-proof bar-coded name tag for easy identification and tracking

Menu Copyright © 2005 by The SEA Group Features The special test adapter can be used on the wearer’s own mask without leaving any marks

Menu Copyright © 2005 by The SEA Group How to fit Adjust the tension by using the buckle, if needed 4

Menu Copyright © 2005 by The SEA Group How to fit Pull a few times on the BOTTOM strap. This will create more tension in the upper strap, resulting in greater lift and optimum balance 5

Menu Copyright © 2005 by The SEA Group Leakage test Perform a leakage test every time you will use the mask Place the leakage test disk instead of a pre-filter in the pre-filter holder Breathe in and hold your breath The mask collapses against your face. It should stay collapsed until you release your breath. If it returns quickly to normal shape, you have a leakage problem

Menu Copyright © 2005 by The SEA Group Annual fit test Individual fit testing using PortaCount or similar equipment should be performed at least once a year This will ensure that people whose facial features have changed (due to dentures, lost teeth, severe acne, facial scarring etc) are still receiving the protection they need
