Original FIAC spa spare part - Pump Unit AB998. Part number: 1123020166

Genuine FIAC spa Air Compressor Pump Unit - Model AB998 (Part No. 1123020166)

Product Description:
The genuine FIAC spa pump unit, part number 1123020166, is a heavy-duty, high-performance industrial block engineered for professional belt-driven air compressors. The AB998 model features a twin-cylinder, oil-lubricated setup with an advanced two-stage compression design (two cylinders of differing diameters compressing air in consecutive phases). This configuration allows the unit to deliver higher working pressures with superior volumetric efficiency while significantly minimizing thermal buildup.

Crafted entirely from heavy-duty cast iron for unparalleled wear resistance, the AB998 comes equipped with a large, precision-balanced multi-blade flywheel designed to force a massive cooling airflow directly over the cylinders and interstage coolers. This OEM replacement pump block is the definitive solution to overhaul industrial belt-driven compressors, completely restoring factory-spec air displacement (CFM / L/min) and maximum pressure ratings.

Key Features:

•     High-Efficiency Two-Stage Technology: Two-phase compression reduces mechanical stress, lowers internal running temperatures, and optimizes energy consumption compared to single-stage alternatives.
•     Solid Cast-Iron Cylinders: Exceptional durability, rigid structural engineering, and stable piston-to-cylinder tolerances even under continuous, heavy-duty operational loads.
•     Superior Thermal Management: Aerodynamically finned flywheel combined with large intercooler manifolds ensures rapid heat dissipation, preventing overheating during long duty cycles.
•     Genuine FIAC Reliability: 100% authentic OEM factory spare, guaranteeing flawless mechanical fitment, certified safety standards, and preserving the lifetime value of your machinery.
