Honeywell North CF4000 Series Front Mount CF-SAR

The Honeywell North CF4000 Series is a front mount Continuous Flow Supplied Air Respirator (CF-SAR).  The CF4000 Series assembly connects to the center port of the Honeywell North RU6500 full facepiece to create a respirator that offers the flexibility of two options:  CF-SAR only or CF-SAR with Air Purifying Respirator (APR) backup.  It particularly benefits users who require respiratory protection across different respirator types.  Together with Honeywell North airline hoses and quick connecting couplers, the CF4000 Series offers a reliable and economic system that provides respiratory protection against most gases, vapors and particulates for extended periods of time.
