DaTo ACMAS301 A/C Service Station for Automatic Refrigerant Recovery and Recharge
A fully automatic A/C service station that runs 8 functions on one hook-up: recover, recycle, vacuum, weighed recharge, oil injection, circuit flush and UV dye leak test. Recovery rate 99% with a 12 L refrigerant tank — the higher tier in this family.

Engineering basis
What makes the difference in daily use
Recovery: 99% of the gas returns to the tank, not the atmosphere
Recovered refrigerant passes the dry filter before it returns to the tank, so it is reused instead of buying a fresh cylinder per vehicle. The gap between 99% and 97% never shows on a single car — it shows cumulatively across a fleet that enters the bay every day, and it is also what separates an environmentally compliant workshop from one that vents.
Automation: eight functions on a single hook-up
The technician connects the two hoses once and the whole cycle runs. That is what makes this the model for a bay servicing several vehicles a day: connect-and-disconnect time happens once rather than six times, and the human error of running the steps out of order disappears.
Measurement: the scale is what separates a correct charge from a guess
Overcharging raises circuit pressure and strains the compressor; undercharging weakens cooling and brings the car back. The weight on the display is what lets the technician charge to the manufacturer’s figure rather than by feel.

How it differs
How the ACMAS301 differs from the ACMAS302 in the same family
Functions: 8 here, including circuit flush and UV dye leak testing. The ACMAS302 covers recovery, vacuum, oil injection and charge.
Recovery and capacity: 99% with a 12 L refrigerant tank here, against 97% and a 10 kg gas cylinder on the ACMAS302.
Evacuation: a 120 L/min pump as standard here, where the ACMAS302 starts at 60 L/min with 120 L/min as an option.

FAQ
Frequent questions about the DaTo ACMAS301
How many functions does the ACMAS301 perform?
Eight: refrigerant recovery, recycling, circuit evacuation, weighed recharge, oil injection, circuit flush, UV dye leak testing, and readout on the display.
What is the refrigerant recovery rate?
99%. Recovered gas passes a 0.122 L dry filter before returning to the 12 L tank.
How long does an A/C circuit flush take?
Between 20 and 60 minutes, depending on the state of the circuit and how much oil and debris it holds.
What electrical supply does it need?
220 V or 110 V AC at 50/60 Hz — it runs on ordinary workshop supply with no dedicated line.
Is the ACMAS301 suited to a bay servicing several vehicles a day?
Yes, and it is the model aimed at that within this family: a 120 L/min vacuum pump and 2 kg/min recharge shorten the cycle, and full automation means one hook-up per vehicle. Put your daily vehicle count in the quotation form and the recommendation is built on it.
