TECHCONNET BlowOff - Air-Blast Systems

Automatic cleaning of ASD pipe-systems

Industry, trade and craft often place high demands on the early fire detection. Especially with suspended solids and dust polluted areas require a high reliability. With TECHCONNET BlowOff Air Blast Systems the fail-safe operation of modern Smoke Aspiration Detectors is optimized.

TECHCONNET BlowOff - Air-Blast Systems


Smoke aspiration detectors - fire safety provided by TECHCONNET BlowOff

The TECHCONNET BlowOff Air-Blast Systems were successfully tested in accordance with EN 54-20 in the test laboratory of VdS with smoke aspiration systems of Honeywell (Xtralis / Vesda) and Wagner. Further tests are running (Bosch and system sensor). The VdS examination created the basis to offer the TECHCONNET BlowOff systems as standard equipment on the world market.

TECHCONNET BlowOff - Air-Blast Systems

Product designs: BO 2.1 HD – BO 2.4 HD / BO 3.1 HD - BO 3.4 HD in 230V AC / 24V DC Versions

The TECHCONNET BlowOff Air-Blast Systems remove suspended solids and dust from the openings of the ASD sensor tube system automatically, several times a day. The TECHCONNET BlowOff maintenance units increase the operational safety of ASD equipment and reduce their operating costs minimizing maintenance work and false alarm costs.

Thanks to the modular design of TECHCONNET BlowOff Air-Blast Units, all conceivable configurations of ASD systems can be operated. Two different enclosure protection classes, as well as the power supplies with 230V AC or 24V DC leave nothing to be desired in the optimal adaptation to the environment. The TECHCONNET BlowOff Air-Blast Systems support heterogeneous ASD environments. Thus, Aspiration Smoke Detectors from different manufacturers with different designs can be combined with the TECHCONNET BlowOff Air-Blast Systems. Of course, even existing systems can easily be retrofitted with the TECHCONNET BlowOff Air-Blast systems.
