The BT100 OFAC 3-Block represents the heavy-duty tier of silent, oil-free technology. By utilizing a triple-pump (3-block) configuration, this unit distributes its 3hp power across six total cylinders. This design provides professional-grade air displacement while maintaining the signature low-noise profile of the OFAC range.Key SpecificationsCapacity: Large 100-liter tank for extended run times and high air reserves.Power: 3hp (2.2kW) total output, typically managed by a staggered start-up to prevent power surges.Triple Block Design: Three independent motor/pump units working in tandem for rapid $CFM$ (Cubic Feet per Minute) delivery.Silent Operation: Despite its size, the multi-cylinder layout allows the motors to run at lower RPMs, significantly reducing acoustic output.
