CB40 series
Applications
The CB40 series respirators meet international
standard requirements in a wide range of commercial, industrial,
security and agricultural activities where inhalation of asbestos,
dusts, fumes, sprays and gases must be avoided by operatives.
Features
Visor –
The polycarbonate visor provides a panoramic, distortion free, wide
field of view.
Face Seal –
The inner mask’s unique reflex edge face seal adapts to the
wearers face contours to provide a good seal under all conditions.
A deep chin cup aids location, provides stability, and enhances
comfort. The combined design of two sizes of the inner mask and
outer mask- fits almost all of wearers internationally.
Exhalation Valve –
The exhalation valve is securely attached to the front fitting with
a push fit to aid maintenance.
Head Harness – A
five-point adjustable head harness provides maximum security. Anti-rotational
studs on the buckles prevent the straps from twisting when not in
use. It is compatible with different helmets.
Neck strap –
A strap is provided to allow the mask to be hung around the neck
prior to use. It can be detached easily if not required.
Connections –
The glass filled nylon front fitting assembly is held on the mask
by 4 screws and a novel clamp providing a reliable seal. The standard
fitting is 40 mm to EN 148/1.
Airflow Management –
Incoming dry air is directed over the visor internal surface to
prevent misting. It then enters the breathing zone within the inner
mask via two non-return inhalation valves. Exhaled air is vented
directly outside through the exhale valve. This valve is at the
lowest point to allow condensed moisture to escape from the mask.
Communication – A
factory fitted 44 mm speech diaphragm provides excellent transmission
of audible frequencies. It is maintenance free. An optional microphone
can be fitted if required.
Visor Clamps –
The glass fitted nylon clamps carry a unique labeling feature for
customized information. The clamps are easily removed for maintenance.
Helmet Capability – CB40
can be worn with a range of protective helmets including fire fighting
and riot control.
