Abstract
The invention relates to an air supply system for two operators equipped with respiratory masks, with continuous monitoring of the minimum flow rate and the quality of CO and CO 2. An alert procedure is provided when limit values are exceeded.
Description
Description
OBJECT AND SUMMARY OF THE INVENTION The invention relates to an air supply system for a respiratory protection mask.
TECHNICAL FIELD [0002] The technical fields for which this technology is applicable are:
All situations or air quality are likely to endanger the health of the operator and / or the air quality values do not comply with the applicable standards (VME). Must use a supply of breathable external air.
DESCRIPTION OF THE INVENTION The proposed system consists of a housing which feeds two operators with breathing air by means of small diameter flexible hoses connected to the CUBAIR by quick couplings. Two independent turbines generate an adjustable air flow to the operators sufficient to guarantee all the safety required during works.
[0004] The system is powered by 230V / 8A.
The air is filtered through a pre-filter and then passes into a chamber where it is controlled by means of CO and CO 2 sensors calibrated in the limit values set by the relevant ordinances.
If the CO and C02 values are exceeded with a safety margin, an alarm and operator safety procedure by an alarm and a cut-off of the air supply is activated, the system leaves the operators The ability to breathe, but given that the air supply is no longer under assistance, the air intake is more difficult, and therefore they will leave the area safely.
[0007] The adjustable air flow rate of each turbine is independent.
A safety system relating to the minimum flow rate is activated to inform by indicator light and to busy due to lack of air or the flow rate too low.
[0009] A minimum flow rate of 240 rpm is guaranteed for each operator and for a distance of between 10 and 50 meters between the CUBAIR and the operators.
[0010] The system is managed by a programmable controller which allows parameterization of the data, according to the adaptation to the needs.
Technical Problems The problems encountered with systems currently on the market are energy-intensive appliances over 380V / 34A against 230V / 8A for the same use.
A weight and a larger size 300 kg for about 1 m3 against 25 kg for a square of 35 cm of side (0.042 m3) A continuous air quality control is integrated into the proposed system Which is not the case in systems found on the market.
Solution The CUBAIR solution has been evaluated by an independent laboratory to determine the characteristics on site and to determine the minimum and ideal values to guarantee the safety of the operators.
[0015] Several measurements have been carried out and have validated the starting hypotheses.
Advantages The main advantages are: weight 25 kg against about 300 kg square dimensions of 35 cm of side ie 0.042 m3 against more than 1 m3
- The required electrical power 230V / 6A against 380V / 34A - Continuous air quality control not available on market systems - Easier and quicker implementation

Claims (4)
1. The CUBAIR is a compact air supply system with flow control for two operators independent of each other and a control of the main air quality values with safety in case of problems Linked to exceedances in the CO and CO2 values outside the limit.
2. The CUBAIR is powered by 230V under 8 AMP for a weight of 25 kg which confers to it a great ease of implementation.
3. The high throughput guaranteed by the CUBAIR makes it possible to put operators in safety even in the difficult situations that the operators can have depending on the work.
4. The CUBAIR is adaptable to all protective masks with 40 mm round threads of EN 148-1.
