34988 Ahead of the Game . . .
Fully compliant with SAE J2788 standards!

Fully automatic function lets you recover, vacuum, leak test, charge, and then walk away.

Combines simple operation with superior accuracy. The 34988 recovers, recycles, evacuates,
leak tests, and recharges R-134a quickly and accurately. Automatic operation means less
attention is needed!

Features:

• Fully-Automatic Function: Program to recover, vacuum, leak test, and charge without operating panel valves.
• Automatic Dye Inject: Gives the user the ability to use the machine to inject UV dye into a vehicle's A/C system.
• Automatic Oil Measure & Inject: The machine will automatically determine how much lubrication oil needs to be injected back into the A/C system based on how much oil was taken out during recovery.
• A/C System Flush: Flushes a vehicle's A/C system with refrigerant, eliminating a residual oil or other liquid. (Flushing adapters sold seperately)
• Save & Print before and after service data: Allows the user to store before and after service information by vehicle, and print this information to provide to a customer.
• Indicator light and notification alarm: Notifies the user when service is complete, or if a problem has occurred.
• Oil Inject: Less than 1% cross-contamination.
• Refrigerant & Oil Database: For North American market vehicles 1994 - 2008. (Optional)
• Vacuum Leak Test: Monitors level after evacuation; informs of possible leak.
• Automatic Air Purge: Eliminates damaging air without monitoring gauges or opening valves.
• Automatic Refrigerant Refill: Maintains a user-selectable amount of refrigerant in an internal vessel and signals when it's time to change supply tank; no monitoring required.
• Vacuum Feature: Defaults to 15 minutes, programmable up to 99 minutes. "Remaining time" is displayed.
• Display: Multilingual
• Refrigerant Charging: Select a charge mode from high-side, low-side, or both.
• Refrigerant Management System: Displays refrigerant use and monitors remaining filter life. Prompts appear when 1/3 of filter life remains.

 

Setting The Course For Change

In June 2005, the Society of Automotive Engineers (SAE) started a research program to reduce the emissions of R-134a. The program, called I-MAC (Improved Mobile Air Conditioning), was tasked with cost effectively improving R-134a systems while reducing refrigerant emissions. The I-MAC members have pledged to design smaller systems with fewer leak points and improve service equipment. As a result of this program, the SAE recently approved tighter standards for automotive A/C recovery, recycle and recharge equipment. The new standard, SAE J-2788, requires that all service equipment manufactured after December 31, 2007, must recover 95% of the refrigerant and recharge to within 1/2 ounce.

How will this affect ME?

For years, R-134a was cheap and plentiful. Today it’s a different story – refrigerant is much more expensive and not always available. The Robinair 34988, 34788 & 34288 recover up to 20% more refrigerant, which means it will cost less to recharge the system. The best charge accuracy that could be claimed by older generation service machines was +/- 1 ounce, a 3% error on a two-pound system. That same charge accuracy on a 14-ounce system is over twice the error (7%). Early R-134a systems could still provide some cabin cooling when they were 4-6 ounces (12-18%) low on refrigerant. However, new designs are so efficient, they do not have reserve refrigerant, and charge accuracy is critical. The 34988, 34788 & 34288 will recharge the vehicle to within 1/2 ounce of the charge capacity, and you will avoid the dreaded “come back”. As the shop owner, you will realize more profits per service by recovering more refrigerant and charging less. Refer to the ROI worksheet on the back of this brochure to determine your actual cost savings. The savings will be obvious.
