RENOLIN AC32 and AC46 are intended primarily for the lubrication of rotary screw type compressors. Final selection should be in accordance with equipment manufacturer’s recommendation. RENOLIN AC68 and AC100 are intended primarily for the lubrication of reciprocating compressors according to manufacturer’s recommendations. Both products may be used for the drip feed lubrication of gears and drive mechanisms in certain screw compressors where oils of this viscosity are stipulated by the machine manufacturers. RENOLIN AC68 and AC100 may also be used in certain sliding vane type compressors where oils of this viscosity are recommended by the equipment makers. Provide minimum drain intervals of 2000hrs in screw and 1000hrs in vane use. RENOLIN AC150 is intended primarily for the lubrication of sliding vane type compressors and is approved by Hydrovane for use in machines of their manufacture for 500 hour drain periods. The range may be used in most vacuum pump applications where the viscosity is appropriate.
