Description
Bosch RG 4.0 is a high-pressure, oil-less refrigerant recovery unit built for licensed HVAC/R pros who need speed and reliability on A1, A2L and A3 gases. It’s compact, tough and simple to service — the kind of kit that keeps you moving between callouts, no worries.
Key Features & Trade Benefits
- A2L & A3 certified — externally certified for A1/A2L/A3; work confidently with R32, R1234yf, R290, R600a. Benefit: compliance and safety on modern low-GWP jobs.
- Oil-less single-cylinder compressor — handles liquid & vapour. Benefit: less maintenance, reliable performance.
- High push-pull rate up to 410.5 kg/hr — plus 122.1 kg/hr liquid and 10.7 kg/hr vapour. Benefit: quicker turnarounds and fewer bottlenecks.
- Low-pressure auto cut-off — smooth stops at target vacuum to reduce wear. Benefit: protects the machine and saves time.
- Robust housing with protective gauge cover — impact-resistant design for site use. Benefit: durability in utes and rooftops.
- High-flow fan, condenser-first airflow — maintains recovery rates in hot conditions. Benefit: steadier performance on 40-degree roof decks.
- Service-friendly layout — bottom-mount assembly; connections on opposite ends. Benefit: faster troubleshooting and hose management.
Why This Product Matters
Up on a tin roof in January, you want a recovery unit that won’t skip a beat. A Brisbane contractor told us the RG 4.0 kept pulling hard on R32 when a cheaper unit started thermal-limiting — this Bosch was a bloody ripper for hot-weather reclaim. That consistency means fewer delays, fewer call-backs, and happier clients.

Pro Tip
For A2L/A3 jobs, use short 1/4″ hoses with ball valves and keep your cylinder on a calibrated scale. Pull out Schrader cores when safe to reduce restriction and you’ll see the RG 4.0 hit its stride — too easy. (Always follow site SWMS and ignition-source controls.)
