34288NI RRR Machine A/C, 29 In L

The Robinair 34288NI is a professional-grade recovery, recycling, and recharging machine for use with R-134a vehicle air conditioning systems. This RRR machine features a single-pass system that meets industrial standards for recycled refrigerant by filtering it through a specialized filter once before storage.

Core Functionality:

• Automatic Recovery and Oil Drain: The machine initiates a self-clearing cycle to remove internal refrigerant and performs a timed vacuum, deep recovery process. It then automatically drains system oil and prompts the user to measure the amount removed for replacement.
• Vacuum Performance: Equipped with a 1.5 CFM vacuum pump, the unit removes air and moisture from the A/C system. A 10-minute default evacuation time is provided, though it is user-programmable up to 99 minutes.
• Precision Recharging: The unit provides a manual charge mode with a high-side default path. It allows users to toggle between high-side, low-side, or both-side charge paths as required.
• Integrated Automatic Function: A dedicated "AUTOMATIC" icon allows users to perform a full recovery, vacuum, and charge sequence in one operation. Hardware and Design:
  • Internal Storage Vessel (ISV): Features a refillable internal tank with a 10 kg (22 lb) capacity.
  • Control Interface: Utilizes a 4.3-inch graphical color LCD and a multi-tap numeric keypad for navigation and data entry.
  • Manifold Gauges: Includes high-side (red) and low-side (blue) Ø 80 mm manometers for real-time system monitoring.
  • Service Hoses: Arrives with 9-foot (2.75 m) service hoses that meet SAE J2196 standards.
  • Filter System: Uses a spin-on filter (Robinair No. 34724) with a total life capacity of 68 kg (150 lb).
