Description

Intrinsically safe

For work in many ignitable or explosive atmospheres

The intrinsically safe Sundström SR500ex powered air purifying respirator designed and approved for use in explosive or ignitable atmospheres. It is an alternative to negative-pressure filter respirators in situations where these are recommended. The fan-assisted air flow may be of benefit during extended periods of work in warm conditions. The fan can be used with most Sundström hoods, face shields or full face masks. It is important to understand that the entire SR500ex system and its individual parts have been certified as intrinsically safe.

 New Lithium-ion Battery and charger now available.

Features

  • Intrinsically safe
  • Single-button operation
  • Visible and audible alarms in case of interrupted air delivery
  • NiMh battery: Up to 6.5 hours’ operation, Approximately 2 hours’ recharge time
  • Lithium-Ion battery: Up to 12 hours’ operation, Approximately 2 hours’ recharge time to 80%
  • Supplied with 2 filters/cartridges/combinations
  • Can be used with hoods SR520, SR530, SR561, SR562, SR601, SR602, Face Shield SR540 EX (discontinued) SR570, Helmet with Visor SR575, SR580 and full-face mask SR200

  • Description: Intrinsically safe (i.e. for use in explosive or ignitable atmospheres) battery-powered, fan-assisted air-purifying respirator that can be used as an alternative to negative-pressure filter respirators where these are recommended. This applies particularly to extended periods of hard work in warm conditions. The fan can be used with certain Sundström hoods, face shields or full face masks. The fan unit is fitted with a suitable filter, and the filtered air is fed through a hose to the facepiece.
