B-SECURUS filter monitoring – The safety system for breathing air treatment
The B-SECURUS system monitors the saturation of the filter cartridge(s) by measuring the residual humidity of the compressed air in the molecular sieve of the P-filter system and outputs an “advance warning” on the display or compressor control indicating when the filter cartridge(s) should next be changed.
The service life of the cartridge(s) cannot be exceeded¹ because the advance warning signal draws attention to the saturation of the filter cartridge(s) in plenty of time.
Depending on the size of the compressor, the advance warning signal will be output approx. 1 to 7 hours before cartridge saturation. B-SECURUS automatically switches the compressor unit off if the cartridge is saturated and has not been changed.
Safety switch-off will also occur in the event of a cable break and if the B-SECURUS is not connected to the unit control.
If the filter cartridge(s) are missing in the P-filter system, the compressor cannot be switched on. A message appears on the display accordingly.
The B-SECURUS filter monitoring system ensures that the compressed breathing air is as clean as possible in accordance with DIN EN 12021¹ as well as maximising the service life of the BAUER filter cartridge(s) used. The cost of purchasing the B-SECURUS thus pays itself off within a short time. The B-SECURUS system does not have to be calibrated.
¹ If the units are maintained and installed correctly as described in the user manual and subject to the BAUER AERO-GUARD being used if CO2 concentration in the intake air exceeds prescribed standard values.
