Mechanic Falls, Maine — The new AEGIS SGR Conductive MicroFiber Shaft Grounding Brush from Electro Static Technology improves the reliability of HVAC/R systems by dramatically extending motor life, the company reports. By protecting bearings from electrical damage for the life of the motor, the AEGIS SGR prevents bearing noise and costly motor repairs and downtime. It is ideal for OEM motor and fan manufacturers, repair shops, HVAC service contractors, and in-house maintenance departments and can be easily installed as part of a preventive maintenance program. The AEGIS SGR is easily installed by sliding the brush over either end of the motor shaft and locking it in place with simple screw-on mounting brackets.  Because no machining is required, the SGR can be installed in minutes — even in the field. Unlike conventional shaft grounding brushes, the AEGIS SGR’s conductive microfibers work with virtually no friction or wear and last for the life of the motor, with no RPM limitations. www.est-aegis.com.
