Description
Product Description
The Atlas Copco ZT18-37 Old Unloader Valve Service Kit (PN: 2901141200) is a factory-certified maintenance solution developed to sustain the high-precision air regulation required by oil-free compressed air infrastructures. On legacy oil-free models—including the ZT18, ZT22, ZT30, and ZT37 series—the unloader valve assembly undergoes continuous cycling stress.
Utilizing this dedicated service kit replaces critical high-wear parts, effectively eliminating internal bypass leaks, stabilizing downstream air delivery, and preventing unexpected, costly industrial production downtime.
Key Features & Advantages:
Targeted Legacy ZT Series Fitment: Precision-matched to seamlessly integrate with the inlet/unloader valve assemblies of early-generation Atlas Copco ZT 18 / ZT 22 / ZT 30 / ZT 37 oil-free compressors.
Premium Fluorocarbon Elastomers: Outfitted with top-tier O-rings and piston seals configured to reliably withstand fluctuating high-temperature industrial air flows without hardening or cracking.
Restores Loading Efficiency: Counteracts lagging response thresholds during load-to-unload cycles, stabilizing system airflow and reducing unnecessary motor strains.
Comprehensive Consumable Bundle: Houses all critical sealing rings and wear elements under a single part number, streamlining your procurement cycle and speeding up routine maintenance intervals.
