3.1 Choose your Headtop
Choose among a wide selection of headtops to meet the
requirements of your workplace, from lightweight hoods to
industrial helmets, that provide not only respiratory protection,
but also eye and face protection, head protection, and optionally,
hearing protection.
3.2 Choose your Air Delivery Unit
To handle the contaminant situation at your particular
workplace, you have the choice between two filtering powered
air systems and three supplied air regulators. You also need to
choose the right filters for the contaminant situation when using
powered air systems.
3.3 Choose your Breathing Tube
The breathing tube reliably connects the headtop to the air
delivery unit, ensuring an unrestricted flow of breathing air.
To meet the high respiratory performance requirements,
the S-Series headtops connect to all air delivery units via the
new BT-Series breathing tubes. Additional breathing tubes are
available that are compatible with the 3M™ HT-100, HT-400,
HT-600, HT-700 and HT-800 Series modular headtops.
