Anest Iwata OFB-5 Oil-Free Reciprocating Compressor

The Anest Iwata OFB-5 is part of Anest Iwata’s OF (Oil-Free) reciprocating range. PTFE piston rings and a dry crankcase guarantee zero oil carryover into the compressed-air stream while maintaining the high peak-pressure capability characteristic of piston compressors.

Anest Iwata has been manufacturing oil-free compressed air solutions in Japan since 1926. Their scroll and reciprocating ranges are the standard in industries where air purity is mission-critical — medical, dental, pharmaceutical, semiconductor, food and beverage, laboratory, and precision spray finishing. Every Anest Iwata oil-less compressor delivers Class 0 air (ISO 8573-1) at the compression element, eliminating the cost and risk of downstream oil contamination.

Why Oil-Free Reciprocating?

• Class 0 oil-free air at the source — PTFE-faced piston rings and dry-sump crankcase eliminate any path for oil to reach the compressed-air stream.
• Higher peak pressure capability than scroll — ideal for PET bottle blowing, laser cutting assist gas, and dental/medical where ~145 PSI minimum is required.
• Heavy-duty cast cylinder construction with thermo-stable valve plates for long service intervals.
• Fully serviceable — piston ring kits are field-replaceable; no special tools required.
