Powerex STD10B4 Series 10 HP Duplex Oil-Less Scroll Air Compressor
The Powerex STD10B4 Series 10 HP Duplex Oil-Less Scroll Air Compressor is engineered for applications that require continuous, redundant, oil-free compressed air with quiet operation and long-term reliability. Featuring two independent oil-less scroll compressor pumps, the STD10B4 delivers automatic load sharing and uninterrupted air supply for critical clean-air environments where downtime is not acceptable.
The duplex configuration allows each scroll compressor to operate independently in a lead/lag sequence, extending component life while ensuring built-in redundancy. When air demand increases, both compressors operate together to maintain stable system pressure under standard operating conditions.
This system is ideally suited for medical, laboratory, pharmaceutical, food processing, and clean manufacturing environments where air purity and uptime are essential.
Clean, Quiet, Oil-Free Duplex Performance
The dual 10 HP oil-less scroll compressors operate with extremely low vibration and sound levels, making the STD10B4 suitable for installation in occupied or noise-sensitive environments.
The system comes standard with electronic condensate drains, automatically removing moisture from the air receiver and protecting downstream equipment without manual intervention.
Because the compressor system is completely oil-free, users benefit from:
-
No oil changes
-
No oil carryover
-
No oil-water separators required
-
Reduced downstream filtration requirements
Pressure Configuration
-
Standard pressure configuration only
(The STD10B4 is not offered in a 145 PSI high-pressure configuration.)
