Features
120 L/min Dual-Stage Vacuum Pump Performance
The AC2100 1234yf machine's 3.6 CFM dual-stage vacuum pump pulls down to 1 mBar resolution, significantly faster than single-stage competitors.
Precision Load Cell Weighing System
Both gas and oil load cells measure to 0.04 oz accuracy across their 66 lb (30 kg) range.
Integrated Filtration and Drying System
This 1234yf machine's spin-on filter-dryer handles 175 lbs (80 kg) of refrigerant before replacement, about 3-4 times longer than standard 50 lb filters.
7-Inch Touchscreen with Vehicle Database
The high-resolution touchscreen guides technicians through each service step with clear prompts and real-time gauges.
SAE J2788 Compliant Service Hoses
The 9.8-foot (3-meter) hoses meet SAE J2788 standards for R-1234YF service, with low permeation barriers that prevent refrigerant loss.

Call (855) 498-2147Frequently Asked Questions
What size electrical circuit does the Katool AC2100 need for operation?
The AC2100 requires a dedicated 110V AC, 60Hz outlet with a 20-amp circuit breaker. The unit draws 12-15 amps during compressor startup and runs continuously at 8-10 amps during normal recovery operations.
How often should I replace the filter-dryer on the AC2100?
The 175 lb (80 kg) capacity filter-dryer typically lasts 200-300 vehicle services or 6-8 months in average shop use. The touchscreen displays a counter showing refrigerant processed, and you'll notice longer recovery times when the filter approaches capacity.
Can the AC2100 be used as a freon recovery machine for older cars?
Yes. While optimized for R-1234yf, the AC2100 functions as a fully capable freon recovery machine for R-134a vehicles (commonly referred to as Freon) when equipped with the optional hose kit. You must thoroughly flush the system between refrigerant types following the manual's cross-contamination prevention procedure.
What maintenance does the dual-stage vacuum pump require?
Check vacuum pump oil level weekly through the sight glass and change it every 60 hours of operation or when it appears cloudy. The pump uses standard vacuum pump oil (ISO 100 viscosity), and a full oil change requires 500 mL.
How accurate is the refrigerant charging on the AC2100?
The load cells maintain 0.5 oz (15 g) accuracy throughout the 41-122F operating range. The system automatically compensates for temperature variations and hose weight, achieving the SAE J2788 standard requirement of 0.5 oz precision.
What vehicles are included in the SD card database?
The database covers domestic and import vehicles from 2011 forward that use R-1234YF, including hybrids and EVs. Updates are available quarterly from Katool's website, and you can manually enter specifications for vehicles not listed.
How long does a complete recovery and recharge cycle take?
A typical passenger vehicle with 1.5 lbs of refrigerant takes 35-45 minutes total: 10 minutes for recovery, 8-10 minutes for vacuum, 5 minutes for leak test, and 3-5 minutes for recharge. Larger systems or those requiring deep vacuum may take 50-60 minutes.
Will the AC2100 work in a cold shop during winter?
The machine operates down to 41F (5C), but recovery efficiency drops below 60F. The optional heating belt maintains optimal tank temperature in cold conditions, ensuring the 95% recovery rate even at minimum operating temperature.
