Sundström SR700 powered air-purifying respirator

A slimmed-down version of Sundström’s powered air-purifying respirator (PAPR) is now available. The SR700 model has the same air delivery capabilities as its bigger counterpart, the SR500, but is designed for protection against particles only. It is suitable for any situation where filter protection against hazardous particles or nuisance dust is required or recommended.

The lightweight fan unit gives a choice of airflow of 175 or 225 L/min and can be connected to all Sundström supplied-air headpieces, such as full-face mask, soft hoods, rigid face shields and the SR580 helmet with visor. The unit uses two high-efficiency particle filters, with a separation capacity of more than 99.997%.

The product is designed for optimum mobility, weighing 1.1 kg including battery and filters. The detachable lithium-ion battery provides up to 8 h of operation and can be recharged in 2 h.

Operation is simple, with a single control for start, stop and selection of fan speed. The clear display shows the operating status of the respirator, and audible and visible alarms warn of any obstruction to the airflow.
