Schulz SCR 4005 Oil-Less Scroll Air Compressor (5 HP, 12.5 CFM)

The Schulz SCR 4005 is an oil-less scroll compressor delivering 12.5 CFM at 145 PSI from a 5 HP (3.7 kW) drive. ISO 8573-1 Class Zero certified — zero oil in the compressed-air stream — making it the right choice for critical-air applications: hospital, pharmaceutical, cosmetic, dental, food, beverage, semiconductor, and clean manufacturing.

Scroll Technology — Why Oil-Less Matters

• ISO 8573-1 Class Zero certified — the highest air-quality class. Oil flow, vapor, and mixture are completely absent from the air stream. Conventional coalescing filters cannot remove oil vapor — only a true oil-free compressor like the SCR series can.
• 4-stage scroll mechanism — fixed scroll + orbiting mobile scroll, no rubbing pistons, no rings, no lubricant in the compression chamber.
• Integrated dryer and tank options — Total Solution packaging gives you compressor + dryer + tank in one footprint, simplifying installation and reducing piping complexity.
• Oversized radiator for increased machine performance and consistent output across the duty cycle.
• 24V safety control with general disconnect — total panel shutdown for service safety.
• Temperature sensor protects the compressor unit from over-temperature events.
