Product Description

Product Description

This piston compressor supplies clean, oil-free compressed air for modified atmosphere packaging systems used in fresh meat, cheese, and produce processing, where gas purity directly affects product shelf life and visual appearance. Its oil-free compression chamber with self-lubricating carbon piston rings delivers ISO 8573-1 Class 0 air, preventing hydrocarbon carryover that can alter the gas mix ratio inside the package. A precision pressure regulator maintains output within ±0.05 bar, ensuring consistent gas flow to the MAP machine's mixing manifold for accurate nitrogen, oxygen, and carbon dioxide proportions. The unit features an integrated high-efficiency coalescing filter and activated carbon adsorber that remove oil vapor, particles, and odors, delivering neutral tasting, odorless air for food contact. All gas-wetted components are constructed from FDA-compliant 316L stainless steel and anodized aluminum to prevent corrosion from cleaning agents. A compact, waterproof enclosure (IP65 rated) allows washdown cleaning in food processing facilities. The compressor includes an automatic start-stop controller with sleep mode, reducing energy consumption during packaging line changeovers. Remote monitoring via Ethernet IP provides real-time pressure, filter life, and runtime data for HACCP documentation.

Key Features & Selling Points

(1) Oil-free self-lubricating carbon piston rings deliver ISO 8573-1 Class 0 air, preventing gas composition deviation in MAP packaging.

(2) Precision pressure regulator maintains output within ±0.05 bar, ensuring consistent gas mix ratios for extended shelf life.
