Robinair AC1234-4SL Premier R-1234yf Recovery, Recycle & Recharge Machine

AC1234-4SL Premier R-1234yf Recovery, Recycle & Recharge Machine For Mobile Service

Mobile A/C service requires equipment that can handle transportation while maintaining accurate refrigerant measurements. The Robinair AC1234-4SL Premier R-1234yf Recovery, Recycle & Recharge Machine is designed specifically for mobile service, featuring a mechanical scale lock that helps protect the refrigerant scale during transport and reduces the need for recalibration.

Fully automatic operation handles refrigerant recovery, recycling, evacuation, leak testing, charging, oil draining, and internal tank refilling with minimal operator input. The integrated refrigerant identifier checks the refrigerant before recovery, while the 98.5% recovery efficiency and ±0.5 oz. charge accuracy provide consistent service performance for standard and high-voltage vehicle A/C systems.

Built for mobile automotive technicians, the AC1234-4SL includes extra-long 12 ft. service hoses, tie-down points, transport guidelines, and a safety startup feature that prevents operation when the scale lock is engaged. It meets SAE J2843 standards and includes a 1.5 CFM vacuum pump, 21 lb. internal refrigerant capacity, and 450 PSI maximum pressure.

Forklifts and Lift Gates

All of our Single Post, 2 Post, and 4 Post Lifts* require a forklift (or similar) to unload.  Tire Changers and Balancers and other small items allow for a lift gate service (At no additional charge) Lift gate service will lower your order to street level.  How do I know if a forklift is required? See the drop down options that show when you're attempting to place an order. 

What if I don't have a forklift at my location and my order requires it?

This is a common question and here's some alternatives:

• We can deliver to a local freight terminal near you.  Typically this is within 30-60 minutes away depending on location.  We will find a location - Contact Us
• Do you have a buddy that owns a forklift and we can ship it there?  Does your place of work have a forklift?  Select this location as the delivery address. 
• Warehouse pickup - This is always an option but depends how far you're willing to drive. 
• Rent a forklift - This is the least favorable option but may be necessary.  We always schedule the delivery so this should minimize the days required to rent.

Can I hand unload my order if I don't have a forklift? 

No, sorry, the truck drivers don't allow for this.  2 things: Liabilities and the time it takes to unload - truck drivers can't wait, even if you have an army of help. 

How do I know if my order requires a forklift or if a lift gate service is available?

Freight Terminals

If you don't have a forklift at your location, we can find you a freight terminal in your area and they will load your trailer onsite.  (Typically 30-60 minute drive away, depending on location) Special note: Some orders are so large they ship on a flatbed by themselves, in these cases a freight terminal delivery is not an option.  The product page will state whether this is the case.
