Summit Industrial Products



Summit AU-46 is a silicone-based synthetic compressor oil designed for use in rotary screw compressors. AU-46 does not breakdown under normal operating temperatures and pressures thereby eliminating carbon deposits, sludge and varnish formations.  The system stays clean of lubricant by-products resulting in lower maintenance costs.  The high viscosity index insures a minimum change in viscosity over the compressor's temperature range.  AU-46 has excellent water separation, corrosion protection and lubricity characteristics.

Recommended uses

Recommended Uses: Summit AU-46 is designed specifically for use in rotary screw compressors. It can handle a wide range of operating temperatures.
