The compression chambers run completely free of oil, and the package carries the ISO 8573-1 CLASS 0 (2010) certification verified by T\u00dcV.<\/p>\n<p>Three pressure versions at 50 Hz and three at 60 Hz cover free air delivery from 123.1 to 160.2 l\/s, and the Full Feature build integrates the IMD adsorption dryer inside the same package. The water-cooled design turns the compression heat into a resource instead of a loss.<\/p>\n<h2>Where the ZR 55 Sits in the Oil-Free Range<\/h2>\n<p>The ZR\/ZT 55-90 family serves the plants whose oil-free demand fits a compact package instead of the larger ZR\/ZT 110-275 class, and the ZR 55 carries 55 kW of installed motor power at the entry of the range. The letter Z marks the oil-free architecture: the precision-cut rotors never touch, so the compression chamber needs no lubrication and no oil can reach the air stream. Where the demand profile swings, the ZR 55 VSD of the same rating adjusts its speed continuously instead of loading and unloading.<\/p>\n<p>Atlas Copco pioneered oil-free air technology over sixty years and became the first manufacturer awarded CLASS 0 certification. The ZR 55 brings that standard into the water-cooled 55 kW class, and the package arrives as a complete all-in-one installation: place it on a flat floor, connect the power line, the cooling water circuit and the air outlet, and push the start button.<\/p>\n<h3>\u0641\u0631\u0639\u0627\u0646\u060c \u0645\u0646\u0635\u0629 \u0648\u0627\u062d\u062f\u0629<\/h3>\n<p>Two names describe the branches of the ZR 55, and each adds one fact:<\/p>\n<ul>\n<li>\u0627\u0644\u0645\u0639\u064a\u0627\u0631 \u2014 \u062a\u0648\u0641\u0631 \u0648\u062d\u062f\u0629 \u0627\u0644\u0636\u0627\u063a\u0637 \u0647\u0648\u0627\u0621\u064b \u062e\u0627\u0644\u064a\u0627\u064b \u0645\u0646 \u0627\u0644\u0632\u064a\u062a \u0644\u0644\u0634\u0628\u0643\u0627\u062a \u0627\u0644\u0645\u0632\u0648\u062f\u0629 \u0628\u0646\u0638\u0627\u0645 \u0645\u0639\u0627\u0644\u062c\u0629 \u0647\u0648\u0627\u0621 \u062e\u0627\u0631\u062c\u064a \u0641\u064a \u0627\u0644\u0645\u0631\u062d\u0644\u0629 \u0627\u0644\u062a\u0627\u0644\u064a\u0629\u060c \u062d\u064a\u062b \u064a\u0639\u0645\u0644 \u0627\u0644\u062a\u0635\u0645\u064a\u0645 \u0627\u0644\u0645\u0628\u0631\u062f \u0628\u0627\u0644\u0645\u0627\u0621 \u0639\u0644\u0649 \u0637\u0631\u062f \u062d\u0631\u0627\u0631\u0629 \u0627\u0644\u0636\u063a\u0637 \u0625\u0644\u0649 \u062f\u0627\u0626\u0631\u0629 \u0645\u064a\u0627\u0647 \u0627\u0644\u062a\u0628\u0631\u064a\u062f.<\/li>\n<li>FF \u2014 \u0627\u0644\u0645\u064a\u0632\u0629 \u0627\u0644\u0643\u0627\u0645\u0644\u0629: \u062a\u062a\u0636\u0645\u0646 \u0627\u0644\u062d\u0632\u0645\u0629 \u0645\u062c\u0641\u0641 \u0627\u0644\u0627\u0645\u062a\u0635\u0627\u0635 IMD\u060c \u0648\u0628\u0627\u0644\u062a\u0627\u0644\u064a \u064a\u062e\u0631\u062c \u0627\u0644\u0647\u0648\u0627\u0621 \u0627\u0644\u062c\u0627\u0641 \u0645\u0646 \u0627\u0644\u062c\u0647\u0627\u0632 \u0645\u0628\u0627\u0634\u0631\u0629\u064b \u062f\u0648\u0646 \u0627\u0644\u062d\u0627\u062c\u0629 \u0625\u0644\u0649 \u0627\u0633\u062a\u0647\u0644\u0627\u0643 \u0637\u0627\u0642\u0629 \u062e\u0627\u0631\u062c\u064a\u0629 \u0644\u0639\u0645\u0644\u064a\u0629 \u0627\u0644\u062a\u062c\u062f\u064a\u062f.<\/li>\n<\/ul>\n<p>Every version combines with both branches, and both branches share the same 2,180 mm footprint.

Electronics manufacturers use the clean, dry air for removing microscopic debris from chip and board surfaces, and petrochemical sites value the machine&#8217;s ability to run in extreme temperatures and humidity conditions around the clock.<\/p>\n<p>Pharmaceutical production completes the picture, from fermentation and tablet coating to packing and bottling, where 100 percent oil-free air protects both the process and the brand. Where the demand profile fluctuates heavily, the plant adds the ZR 55 VSD of the same rating next to this fixed-speed machine, and growing networks step up to the ZR 75 of the same platform.<\/p>\n<h2>Service and Support Around the ZR 55<\/h2>\n<p>The ZR 55 is built for long overhaul intervals, few service interventions and minimal maintenance cost, and every machine is tested before delivery to ensure it meets the specifications. A global service operation with field service engineers across 160 countries backs the installed base, and genuine Atlas Copco parts keep the package at its rated performance.<\/p>\n<p>Seadweer supplies genuine Atlas Copco spare parts and service kits for the ZR 55 and its Full Feature branch, and the parts coverage follows the same platform index as the ZR 55 VSD and <a href=\"https:\/\/www.compressorpartsmall.com\/ar\/product\/%d8%a3%d8%b7%d9%84%d8%b3-%d9%83%d9%88%d8%a8%d9%83%d9%88-zr-90-vsd-%d8%a7%d9%84%d8%ae%d8%a7%d9%84%d9%8a-%d9%85%d9%86-%d8%a7%d9%84%d8%b2%d9%8a%d8%aa\/\">the larger ZR 90<\/a>. \u0623\u0631\u0633\u0644 \u0625\u0644\u064a\u0646\u0627 \u0637\u0631\u0627\u0632 \u0627\u0644\u0636\u0627\u063a\u0637 \u0645\u0639 \u0642\u0637\u0639 \u0627\u0644\u063a\u064a\u0627\u0631 \u0627\u0644\u062a\u064a \u062a\u062d\u062a\u0627\u062c\u0647\u0627\u060c \u0648\u0633\u0646\u0642\u0648\u0645 \u0628\u062a\u0623\u0643\u064a\u062f \u0627\u0644\u0642\u0637\u0639 \u0627\u0644\u0635\u062d\u064a\u062d\u0629 \u0645\u0639 \u0639\u0631\u0636 \u0627\u0644\u0623\u0633\u0639\u0627\u0631 \u0641\u064a \u062e\u0637\u0648\u0629 \u0648\u0627\u062d\u062f\u0629.<\/p>\n<figure id=\"attachment_8561\" class=\"wp-caption aligncenter\" style=\"width: 300px;\" aria-describedby=\"caption-attachment-8561\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-8561\" src=\"https:\/\/www.compressorpartsmall.com\/wp-content\/uploads\/2026\/10\/Atlas-Copco-ZR-55-FF-5-300x225.webp\" alt=\"Atlas Copco ZR 55 FF (5)\" width=\"300\" height=\"225\" srcset=\"https:\/\/www.compressorpartsmall.com\/wp-content\/uploads\/2026\/10\/Atlas-Copco-ZR-55-FF-5-300x225.webp 300w, https:\/\/www.compressorpartsmall.com\/wp-content\/uploads\/2026\/10\/Atlas-Copco-ZR-55-FF-5-768x576.webp 768w, https:\/\/www.compressorpartsmall.com\/wp-content\/uploads\/2026\/10\/Atlas-Copco-ZR-55-FF-5-600x450.webp 600w, https:\/\/www.compressorpartsmall.com\/wp-content\/uploads\/2026\/10\/Atlas-Copco-ZR-55-FF-5.webp 800w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><figcaption id=\"caption-attachment-8561\" class=\"wp-caption-text\">Atlas Copco ZR 55 FF (5)<\/figcaption><\/figure>\n<h2>\u0627\u0644\u0623\u0633\u0626\u0644\u0629 \u0627\u0644\u0634\u0627\u0626\u0639\u0629<\/h2>\n<h3>What does the ZR 55 deliver at 7.5 bar?<\/h3>\n<p>The 7.5 bar version delivers 148.3 l\/s at 50 Hz, which equals 8.9 m\u00b3\/min or 314 cfm, measured at 7 bar according to ISO 1217 annex C, edition 4 (2009). At 60 Hz the 7.25 bar version reads 160.2 l\/s (340 cfm).<\/p>\n<h3>Is the ZR 55 water-cooled?<\/h3>\n<p>Yes. The ZR letter marks the water-cooled branch of the ZR\/ZT family: the cooling water circuit carries the heat of compression out of the frame, which holds the sound level at 74 dB(A) and enables heat recovery. The air-cooled equivalent is the ZT 55.<\/p>\n<h3>\u0645\u0627 \u0645\u062f\u0649 \u062e\u0644\u0648 \u0627\u0644\u0647\u0648\u0627\u0621 \u0645\u0646 \u0627\u0644\u0632\u064a\u0648\u062a\u061f<\/h3>\n<p>The ZR 55 carries the ISO 8573-1 CLASS 0 (2010) certification verified by T\u00dcV, the most stringent class of the standard.
