In the case of using a compressor or a compressed air network, always use a purifier filter
capable of delivering an amount of air equal to that required (calculated by the formula
described above). Concerning the characteristics of the medium pressure hose relative
to the compressed air supply, the maximus operating pressure has to be 20 bar, the burst
pressure 54 bar and the maximum length of the hose with which to connect to the sourceis
50 m, achievable with a maximum number of two pieces.
The supply tube of the device from the source of air, which guarantees optimum performance
of the device itself, is the one provided by D.P.I. s.r.l.. This hose is certified according to EN
14593-1: 2005 and fittings compatible with the device itself. The maximum size of the hose is
50m. Other configurations are also realized through extensions can be produced on request
from the D.P.I. s.r.l..
In any case, the normal operating pressure must be between 6 and 8 bar.
The breathable air is delivered by E400 AP/A self positive demand valve, assuring the
presence of a slight positive pressure inside the mask, for any breathing rate up to 300 l/m.
The DIABLO AMIANTE must be used with SFERA SP/A ASB gas masks in EPDM or silicon. The
exhaled air is expelled through the exhalation valves placed on the facepiece, which also
allow an easy drainage of any misting which may form.
On the SFERA SP/A ASB gas mask shall be mounted an ASB P3 particulate filter that is normally
plugged by its cover.
When approaching or leaving the contaminated area, the filter will be unplugged and the
quick coupling on medium pressure, disconnected but protected by its rubber plug.
For further protection, the apparatus is equipped with a medium pressure high efficiency
filter which stops any dust traces trapped while connecting and disconnetting the quick
coupling that is also equipped by one way valve.
The apparatus is also equipped with an audible warning device informing the user if the
medium pressure of the supply air drops below 4.5 bar.
Description of component
The breathing apparatus Diablo Amiante consists of the following components:
• SFERA SP/A ASB
• Particulate filter ASB P3
• Demand valve E 400 AP/A ASB
• Medium pressure filter unit
• Low pressure warning device
• Belt
• Carrying case
Mask: Sfera SP/A ASB
The SFERA SP/A ASB is a positive pressure full face mask equipped with a fully transparent
visor, allowing a virtually unlimited visual field and a quality of vision that is totally distortion
free. Sfera is also equipped with an efficient speech module, which clearly relays the wearer’s
voice over a considerable distance, a rubber half mask and a device preventing the visor from
misting. A high fluid dynamic performance exhalation valve ensures the maximum comfort
at any breathing rate. The rubber harness has adjustable straps and allows a quick donning
of the mask.
