Robinair has introduced its 34988 Premium R-134a Recover, Recycle and Recharge (RRR) A/C machine. The company said the unit provides increased accuracy by giving the user the ability to inject dye; flush a vehicle’s A/C system with liquid refrigerant; save before and after service data; and several new interface options such as a larger operator display screen and database expansion slot that can supply information regarding charge capacity by vehicle model.

It can be used on heavy-duty trucks, on- and off-road trucks, agricultural and construction applications.

An automatic dye inject feature injects UV dye into a vehicle’s A/C system, eliminating the need to use a separate injector. It will also determine how much lubrication oil needs to be injected back into the system based on how much oil was removed during recovery.

The unit also provides a method of removing any liquid contaminants by forcing liquid refrigerant through an A/C system, or components of an A/C system. A special flushing adapter, which can be purchased separately, accesses the A/C system at the compressor block, and flushes a vehicle’s A/C system with refrigerant eliminating any residual oil or other liquid contaminants from the system.

The 34988 also features an indicator light and notification alarm function to notify users when service is complete, or if a problem has occurred.

The unit includes a 1.5 cfm (42 l/m) Robinair high vacuum pump for fast, thorough evacuation. Additional features and benefits include vacuum leak test, automatic air purge, automatic refrigerant refill, refrigerant charging and a refrigerant management system.
