Rothenberger - ROAIRVAC R32 3.0 Two Stage Vacuum Pump, 230V - 1000002713

ROAIRVAC R32 3.0 Two-Stage Vacuum Pump

The ROAIRVAC R32 3.0 vacuum pump by Rothenberger is a professional tool designed specifically for applications with R32, R1234yf, and other A2L refrigerants. With a flow rate of 3.0 CFM (85 l/min), this two-stage pump ensures high and reliable performance for professionals in the refrigeration and air conditioning sector.

Main Technical Characteristics

The ROAIRVAC R32 3.0 operates on 230V power and offers a final vacuum of 0.02 mbar (2 Pa), ensuring an optimal vacuum level for system maintenance operations. The 1/2 HP motor guarantees sufficient power to handle even the most demanding applications, while the 350 ml oil capacity allows for prolonged work sessions before needing refills.

Safety and Compliance

This pump has been specifically designed to operate safely with flammable A2L refrigerants such as R32 and R1234yf. All electrical components are hermetically sealed to prevent any risk during operations with these gases. The pump complies with the latest European safety regulations for equipment intended for handling low-flammability refrigerants.

Functional and Practical Design

The die-cast aluminum body ensures robustness and lightness, with an overall weight of only 9.8 kg, facilitating transport in the field. The integrated ergonomic handle allows for easy movement, while the rubber feet ensure stability during operation and reduce vibrations. The compact design with dimensions of 340 x 140 x 260 mm allows the pump to be easily stored even in limited spaces.

Advanced Features

The ROAIRVAC R32 3.0 is equipped with a gas ballast valve that allows for the expulsion of water vapor and non-condensable gases, improving the efficiency of the evacuation process. The oil level sight glass allows for immediate checking of lubricant conditions, while the integrated non-return valve prevents oil backflow into the system in case of power interruption.

Main Applications

• Installation and maintenance of domestic and commercial air conditioning systems
• Service on industrial refrigeration systems
• Evacuation of systems with traditional and new generation refrigerants (R32, R1234yf)
• Retrofit operations of existing systems with new refrigerants
• Preventive maintenance of HVAC systems

Operational Advantages

The two-stage technology ensures a deeper vacuum and reduced evacuation times compared to single-stage pumps. The forced lubrication system ensures a long life for internal components, while the integrated thermal protection prevents motor damage in case of overheating. The pump is also equipped with standard 1/4, 3/8, and 1/2 inch fittings, ensuring compatibility with most refrigeration equipment.

Simplified Maintenance

The easily accessible drain plug allows for quick and clean oil changes, while the removable suction filter can be easily cleaned or replaced. Rothenberger recommends using its specific vacuum pump oil, which ensures optimal performance even at low temperatures and a longer pump life.
