ABAC B60 and B70 Slow-Speed Compressors: Quiet, Powerful, and Extremely Durable
If you are looking for a compressor for a large workshop environment where continuous operation is required, but you also need to keep noise and wear in check, the low-speed series ABAC B60, B70, and B79 are the right choice.
These two-stage machines, driven by V-belts, operate at extremely low speeds (900–1100 min⁻¹). This design detail significantly reduces mechanical friction, machine noise, and the output air temperature, which directly leads to the delivery of higher quality (cooler) compressed air and extends the unit's lifespan.
- ✅ Cast iron cylinders: Robust blocks with massive ribbing for maximum heat dissipation.
- ✅ Stable pressure 11 bar: Ensures a large accumulated reserve in tanks (270 or 500 l).
- ✅ Full control: Two pressure gauges, an oil level indicator, and two outputs via quick couplings.
- ✅ Safety: Protective plastic pulley guard and motor with thermal protection.
