RRR AC Machine Buss R407C, With Flush, Black Cover

The Nunchi Climate BUSS R407C is a professional air-conditioning service station specifically designed for the larger refrigerant capacities and demanding service requirements found in buses, coaches and other heavy-duty vehicles using R407C.

The machine combines the essential A/C service functions with advanced service capabilities, including system flushing without removing a single A/C component and compressor oil draining.

Advanced Flushing – Without Component Removal

One of the key features of the BUSS R407C is its ability to perform an advanced flushing procedure through the vehicle's A/C system.

The system is designed to allow technicians to flush the A/C system without removing individual components, helping simplify workshop procedures and significantly reduce service time.

This can be particularly valuable on buses and coaches, where A/C systems are large, pipework is extensive, and components can be difficult and time-consuming to access.

The flushing process can help:

• Remove contaminated or excessive oil
• Remove residues and contaminants from the A/C circuit
• Prepare the system following compressor failure or contamination
• Support refrigerant or oil-related service procedures
• Reduce the need to dismantle A/C components
• Reduce workshop labor time
• Improve the quality and efficiency of the service procedure

Compressor Oil Draining

The BUSS R407C also provides the capability to drain and recover oil from the A/C system.

Removing old or excessive oil is particularly important when servicing large-capacity systems. Incorrect oil quantity can negatively affect system performance and may contribute to poor heat transfer or compressor-related problems.

The oil-draining capability allows the technician to better control the amount of oil remaining in the system before the correct quantity and specification are introduced.

Main Functions

• Refrigerant recovery
• Refrigerant recycling
• Vacuum
• Vacuum leak testing
• Refrigerant charging
• Oil management
• Compressor oil draining
• A/C system flushing without removing a single component
• Automatic service procedures

Designed for Large A/C Systems

Bus and coach A/C systems can contain significantly more refrigerant and oil than conventional passenger-car systems. The BUSS R407C is designed specifically with these larger systems and professional heavy-duty workshops in mind.

It provides workshops with a practical solution for conventional A/C service as well as more advanced procedures involving oil management, contamination removal and system flushing.
