Frequently Asked Questions
How does DustGuard™ work?
DustGuard™ uses laser-based sensing technology to analyze engine induction air for the presence of abrasive particles between .5 and 10 micrometers in diameter. If dangerous levels of particles are detected, DustGuard™ alerts local operators and remote supervisors using audible / visual alarms, platform telematics or third-party data systems.
How does DustGuard™ reduce maintenance costs?
DustGuard™ works in conjunction with preventative maintenance procedures and provides a ‘bridge’ between lube oil analyses when induction system leaks are typically detected. DustGuard™ reduces maintenance costs by alerting operators to harmful induction system leaks as soon as they occur thus preventing premature engine wear, damage or catastrophic failure.
Isn’t oil analysis adequate for detecting induction system leaks?
Engine oil analysis reliably detects the presence of silicon dioxide (SiO2) as an indicator of dust ingress and induction system failure; however, the inherent time lag between dust ingress and detection via oil analysis may allow for many hours of operation before corrective action is taken. Typical preventative maintenance cycles can result in hundreds of hours of operation between lube oil analyses exposing the engine to extensive and irreparable harm from induction system failures.
How do particles cause engine damage?
Airborne dust can contain high concentrations of silica particles that can become lodged in the oil film between engine cylinder liners and piston rings. Once lodged within the oil film, the hardness characteristics of the silica particles cause rapid deterioration of the metal surfaces and can rapidly lead to severe wear and engine failure.
Does DustGuard™ require modification of my engines?
No. DustGuard™ is a retrofit technology that has been designed to seamlessly integrate with engine air induction systems using existing ports on both the pressure and suction side of the air intake system.
Does DustGuard™ introduce any additional risk to my fleet?
No. DustGuard™ has been carefully designed as a passive monitoring system that does not introduce any significant operating risks to engines and the machinery they power.
What are the electrical power requirements for DustGuard™?
DustGuard™ is compatible with 12 and 24 volt DC electrical systems and draws a maximum of ~5 amps of current.
How often does DustGuard™ require routine service?
Depending on application, the DustGuard™ system will operate for approximately 12 – 18 months before service is required. The DustGuard™ service kit includes replacement components for internal valves and sensor assemblies and can be completed in approximately two hours.
How does DustGuard™ communicate data and alerts?
DustGuard™ includes a proprietary telematics platform that can communicate via cellular, SWARM satellite, or available radio mesh networks. In addition, DustGuard™ is compatible with third-party data systems using CAN bus J1939 and Modbus communication protocols.
