HEPA filters shall be zoned so that shut downs can be coordinated. Positive-pressure respirators do the work of pushing air to the respirator headtop or facepiece; they can either be powered-air, using a battery-powered blower to pull air through a filter, or supplied-air, bringing clean air through a hose from a source outside of the contaminated work area (refer Appendix A, AS/NZS 1715, requirements for air quality for supplied air respirators). It introduces a great innovation for fine filters (F7, F8 and F9), which must comply with a new parameter: minimum efficiency (ME). Although a Weibull distribution was created for each classification, filter function is identical for each application. Pre-filter : Pre-filter are made from non-woven synthetic with HDPE mesh; conforms to EU 6 grade, with an efficiency rating better than 95% down to 5µ. The limit for respirable dusts that settle on the alveoli determines which filter performance is required. cartridge/particulate filters have approval labels indicating the particulate filter classification TC-84A because the particulate filter is the least protective component of this combination respirator. 97 percent of particles that are 0.
