1. APPLICATION
1.1 Description
Negative pressure full face mask with normalized threaded connection in
accordance with UNI EN 148-1: 2018, two inhalation valves of the internal mask
and an exhalation valve. Harness with five tie rods fixed on the perimeter edge of
the visual screen. The materials of which it is composed allow its use in
atmospheres considered at risk of explosion. To provide respiratory protection, the
mask must be combined with a filter manufactured by Kasco.
It is possible to use the mask as a component of an electric respirator. (See
respiratory composition and related instructions for use in this regard).
1.1.1 Venus1
The sealing body is designed to conform all face shapes in one size. Upon request,
a protective film can be applied to the polycarbonate visor.
1.1.2 Zenith1
Full face mask with black silicone body and panoramic polycarbonate visor.
The device is available in three sizes:
- Size S (small), described above
- Size M (medium), with five tie rods harness fixed on special wings obtained from
the sealing edge
- Size L (large), with harness like size M
The 1005009 ZENITH1 model can be supplied in the following variants:
1005009‐X
From the combination of the variants, 3 codes are obtained:
1005009-S;
1005009-M;
1005009

1.2 Function
Breathable, filtered, air passes through the inhalation valves to the inside of the
visor.
The filtered air flows over the visor minimising visor misting then passes through
check valves to the inner mask.
Exhaled air is expelled through the exhalation valve.
1.3 Reference standards
The full face mask is designed to and complies with the requirements of the
technical standard EN136:1998 and meets the performance requirements laid
down therein.
1.4 Use
The full face mask, with the limitations specified at clause 1.6, may be used
exclusively for respiratory protection against gases and/or liquid and solid aerosols.
See filter/cartridge instructions for permissible concentrations.
1.5 Protection factor
The full face mask protection factor is determined by; the face mask seal, the filter
protection class, the state of conservation and maintenance of the face mask.
1.6 Use Limitations
Do not use the face mask if:
the nature and concentration of the contaminant present in the atmosphere is
not known.
the concentration of the contaminant in the atmosphere exceeds the filter
protection class limits (See filter use instructions).
the type of contaminant is not provided for by the type of filter.
the oxygen concentration in the atmosphere is lower than 17% in volume.
in closed work locations (ex. tanks, duct, silos underground locations) and
fresh air delivery systems are not available.
Use
limitations for PAPR’s may be found in relative Use Instructions
.
1.7 Cautions
The full face mask is to be used only by workers:
who have been trained on the use of respiratory protective devices.
who do not have respiratory problems or an impaired sense of smell.
who do not have sideburns, a beard and/or a moustache as these will hinder a
good face mask seal.
Who do not use eyewear.
Do not use the face mask:
if it has not been thoroughly cleaned and disinfected.
if it has failed the face seal tightness test.
if there is a doubt that parts are missing and/or one or more parts look
defective.
if there is no evidence of period maintenance.
with oxygen cylinders or in oxygen enriched atmospheres.
Return to fresh, clean air immediately and remove face mask in the case:
of uncommon smell or taste.
of unjustified or sudden irritation of the nose or throat .
of inhaled air becoming extremely hot.
dizziness, nausea or headaches occur.
2. CLASSIFICATION
Full face mask for special uses : CLASS 3
3. INSPECTION
Before using the face mask make sure that:
it is clean and disinfected and does not present evident defects.
there are no parts missing.
the inhalation and exhalation valves have been properly inserted.
the filter sealing gasket is properly housed.
4. DONNING AND FITTING
4.1 Donning
Don the face mask before entering the contaminated area.
Release the strap buckles and pull the straps through as far as they will go.
Spread out the two lateral straps.
Slip carrying strap around neck and position chin in the chin support.
Position face mask against the face, pass the harness over the head and pull
straps back in the following sequence: cheek straps, temple straps, forehead
strap.
The ideal position of the mask against the face is obtained when, without excessive
pulling, the mask fits snugly and the seal provides an even pressure distribution
over the entire area in contact with the face.
4.2 Seal Tightness test
After having donned the mask and obtained a good fit press the palm of your hand
over the threaded connector and inhale slightly in order to generate negative
pressure. Hold your breath for a second and if no air leaks are detected a good fit
has been obtained. If air leaks are detected pull straps tighter and repeat test. If
leakage persists reposition the face mask as described at point 4.1 and 4.2 and
repeat seal tightness test.
4.3 Exhalation valve test
Cover the threaded connector with the palm of your hand and exhale. Exhaled air
should flow out of the mask without appreciable resistance.
5 USE
5.1 Aplication:
Some of the uses for which the protective device, equipped with proper filter, has
been designed:
• agriculture: cleaning of stables, sheepfolds and chicken coops. Grain handling

or dry sandblasting.
5.2 Instructions:
Screw on proper filters only after the mask has been tested and has passed the
seal tightness test.
The use of the mask is determined by the type and model of filter used. Follow the
filter Use Instructions packed with filters and, in any case, leave the area
immediately if smell or taste of the contaminant is detected or if breathing becomes
more difficult.
For use in extreme conditions adhere to the following cautions:
In the case of extremely low temperatures treat visor with an anti-misting liquid
(compatible with the eyes and skin and which will not damage rubber and
plastic) and regularly check the exhalation valve diaphragm as it could harden
resulting in possible leakage.
In the case of extremely high temperatures leave the area immediately should
vision become obscured.
