Key Features
Intelligent Variable-Speed Control
Advanced VFD technology continuously modulates compressor speed from 40% to 100% capacity, matching motor output to actual air consumption in real time. This dynamic adjustment eliminates wasteful idling and reduces energy costs by up to 35% compared to fixed-speed units, while maintaining stable system pressure.
CLRS7-11D Precision Airend
Engineered with a 76mm male rotor diameter and optimized for pressures from 85 to 190 PSIG, the CLRS7-11D airend delivers consistent, efficient compression across the full operating range. V-belt drive coupling ensures smooth power transmission and simplified maintenance access.
ISO 1217 Certified Performance
All FAD (Free Air Delivery) ratings are independently tested and verified per ISO 1217 Annex C & E standards, guaranteeing accurate, real-world airflow data. Delivers 62.1 ACFM at 110 PSIG, 56.9 ACFM at 130 PSIG, and 43.5 ACFM at 190 PSIG at 60 Hz operation.
Ultra-Quiet Enclosed Design
Operates at just 64 dB(A) at 70% load and 71 dB(A) at full load (per ISO 2151), making it one of the quietest compressors in its class. The fully enclosed cabinet allows near-point-of-use installation without disrupting work environments or requiring separate compressor rooms.
Premium-Efficiency TEAO Motor
Features a 15 HP totally enclosed air-over (TEAO) motor with Class F insulation, 91% minimum nameplate efficiency, and a 1.2 service factor. This robust motor design ensures continuous-duty reliability, thermal protection, and extended service life in demanding industrial applications.
Multi-Voltage Flexibility
Available in 208, 230, 380, 400, 460, and 575-volt configurations to match virtually any facility electrical system. Full load currents range from 46.0A at 230V to 18.4A at 575V, with clearly documented electrical requirements for straightforward installation planning.
