ROTHENBERGER ROMAX 4000 Basic Set Cordless Press Machine with AMPShare 18V 4.0Ah & 2.0Ah Batteries and Charger

The ROMAX 4000 stands apart from conventional press tools by combining 32 kN of pressing force with the flexibility of the AMPShare battery platform. This Basic Set includes two batteries (4.0 Ah and 2.0 Ah) and a charger, so you can start pressing immediately. The brushless motor and Constant Force Technology deliver consistent, reliable joints across a wide range of metal and plastic fittings.

Highlights

• 32 kN pressing force for secure connections up to Ø 108 mm (metal) and Ø 110 mm (plastic)
• AMPShare 18V battery system – compatible with Bosch Professional 18V tools
• Includes 4.0 Ah and 2.0 Ah Li-Ion batteries plus charger for extended runtime
• Brushless motor for longer service life and higher efficiency
• 350° rotating head for easy access in tight spaces
• LED display shows battery status, press cycles, and service interval
• CFT (Constant Force Technology) ensures complete, repeatable presses
• Automatic return after each press cycle for faster operation

In daily use

On site, the ROMAX 4000 proves its worth with a press cycle of just 5–6 seconds. The 4.0 Ah battery delivers up to 160 presses on Ø 28 mm stainless steel, while the lighter 2.0 Ah battery reduces fatigue during overhead work. The tool operates reliably in temperatures from -10°C to +60°C, making it suitable for both indoor and outdoor installations. The service interval of 40,000 cycles or 2 years minimizes downtime, and the LED display keeps you informed of maintenance needs.
