Thông tin chi tiết

The Atlas Copco 2906048400 is a genuine LP element exchange kit built for the ZR450-750 family of oil-free rotary screw compressors . Atlas Copco lists the part as ZR450-750 LP ELMT EXCH KIT . The kit serves the low-pressure (LP) stage of these two-stage machines. When the LP screw element is exchanged, this kit supplies the sealing components required to reinstall and reseal the stage.

This kit is not the screw element itself. The element is the large rotor pair inside the LP stage. The 2906048400 kit is the consumable sealing package that goes with an element exchange. It holds O-rings, gaskets, and seal washers for the LP stage joints. At 455 g and 110 × 110 × 160 mm, the kit is a light, compact service item. It is made in Belgium and carries tariff code 73182200.

Why the kit matters: ZR oil-free compressors deliver ISO 8573-1 Class 0 air. A breach in the LP stage seals can raise interstage leakage and disturb the oil-free barrier. Using the correct genuine kit protects air purity and stage performance on a 450-750 kW machine.

What the Kit Contains

The kit groups the sealing components needed for an LP element exchange. These include O-rings, flat gaskets, and seal washers that close the joints around the LP element and its housing. Each seal type has a clear job. O-rings seal the round grooves between the element and the casing. Flat gaskets close the larger flanges that join the stage to the intercooler. Seal washers keep bolted joints from weeping under vibration. Exact quantities follow the machine s parts book for the relevant model and build. The package ships as one kit so the technician has the correct seals on hand.

Working Principle

The Two-Stage Oil-Free Layout

ZR450-750 compressors compress air in two stages. The LP element draws in ambient air and raises it to an intermediate pressure. The HP element then compresses that air to the final discharge pressure. A water-cooled intercooler sits between the stages. This split reduces per-stage temperature and load, raising efficiency.

The LP Element and Its Seals

The LP element is a precision screw rotor pair running inside a cooled housing. The Z seal design keeps the compression chamber oil-free. Around the element sit O-rings and gaskets that seal the stage to the gear casing and intercooler. Heat and pressure cycles age these seals over time. The 2906048400 kit renews them during an element exchange.

Why a Dedicated LP Kit

The LP and HP stages use different element sizes and seal layouts. Atlas Copco therefore issues a separate kit for each stage. The LP kit (2906048400) fits the low-pressure stage only. The HP stage uses its own kit, 2906048500. Ordering the correct stage kit prevents a mismatc
