The Robinair AC1234-4SL fixes that problem at the source. This mobile ac recovery machine has an integrated mechanical scale lock that secures the internal cylinder to the weighing platform during transport. Lock it before you drive. Unlock it when you arrive. Your calibration stays accurate all day, every stop, no second-guessing.\u003c\/p\u003e\n\u003cp\u003eBeyond the scale lock, this is a fully automatic r1234yf recovery machine that handles recover, recycle, and recharge in one hands-off cycle. The integrated refrigerant identifier (SAE J2927) samples what's in the vehicle before recovery starts, so you're never contaminating your tank with the wrong refrigerant. Recovery efficiency hits 98.5%, charge accuracy stays within +\/- 0.5 oz, and the 12-foot extra-long hoses reach vehicle ports right from your service van without unloading the unit. Standard and high-voltage A\/C systems are both covered.\u003c\/p\u003e\n\u003cp\u003eSafety features are built around how you actually use this thing on the road. A safe startup prevents the machine from powering on while the scale lock is engaged. An indicator light reminds you to lock it down before you drive off. Tie-down points keep the unit stable in transit. This isn't a shop machine with a cart bolted on. It's purpose-built for mobile service from the ground up.\u003c\/p\u003e\n\u003cp\u003eWe carry Robinair replacement filters, pump oil, and maintenance kits so you're not scrambling for consumables between service calls.
