Sundström’s SR700 lightweight Particle Powered Air-Purifying Particle Respirator (PAPR) is suitable for dusty demolition work.
The powerful fan delivers an airflow of 175 or 240 L/min. The fan unit sits securely on a waist belt, and a breathing hose connects it to a hood, shield, tight-fitting mask or other head-top.
The respirator is fitted with twin Sundström high-efficiency particle filters, capable of stopping 99.997% of particles such as dust, smoke, spray, fibres (including asbestos), bacteria, viruses and mould.
In addition, the filters are suitable for both dry and wet environments, and are not impaired by humidity, oil mist or similar. This makes the respirator particularly suitable for demolition work and asbestos removal, where the building is often hosed down and sprayed with water to minimise airborne dust. The unit is Ingress-Protection rated at IP67.
The SR700 is operated by a single button and features a clear visual display and audible alerts. The lithium-ion battery lasts up to eight hours and recharges in less than two.
