Systems of ventilation and healthiness of confined spaces for the remediation of asbestos
Maintaining a healthy work environment is the prerogative of any company.
This is all the more true for companies that deal with asbestos remediation. The standard prescribes the obligation to create
an effective isolation of the intervention area equipped for "static confinement". Furthermore, it is mandatory to have aeration and
ventilation systems that depress the reclamation site from the outside (dynamic confinement).
The system must guarantee an air replacement volume equal to at least four changes per hour.
The extraction of air and the safety of spaces
The air extractors must be installed on the opposite side of the site entrances. The correct position allows
to produce a constant flow of air from the outside to the inside in order to avoid any loss of fibers.
Secondly, the ventilation devices renew the healthiness of the space and reduce the concentration of airborne asbestos fibers
inside the work area. Thanks to the HEPA filters (high efficiency: 99.97 DOP), the polluted air is effectively filtered before
being expelled outside the construction site.
The technologies of the air extraction system
Below, the characteristics of the range of A.R.T. S.r.l ..
-Variable flow rates from 200 to 50,000 m³ / h
-Trolley structure to facilitate transport
-Backward blade fans that ensure a more linear clogging efficiency curve and make better use of absolute filters
-Inverter for adjusting the fan speed that exploit the motor torque for better performance
-Manometers for checking the clogging status of the filter pack
-Signaling devices with alarm and automatic stop in case of broken filter and clogged filter
-Interface socket managed by an external digital pressure switch for automatic speed adjustment or for the automatic start of any reserve extractors
-HEPA filters (high efficiency: 99.97 DOP)
A.R.T. Srl has also introduced a new series of extractors called "AS" which meets our quality standards,
but much lighter and less expensive. Write via the contact form for a quote on air extractors
