Thông tin chi tiết

The Atlas Copco 1616740990 is the OIS M-08 SERVICE oil-injected rotary screw air end — the service-stage rotor-and-bearing assembly that replaces the original production unit on OIS M-08 compressor packages. Atlas Copco also lists the same air end under the production number 1616740980; both numbers order the identical component, so buyers can use whichever their parts system carries.

This air end suits Atlas Copco rotary screw compressor packages built on the OIS M-08 oil-injected screw module. Typical applications include general manufacturing compressed air, pneumatic tool and automation supply, packaging line air, and process air for medium-duty production environments. Atlas Copco determines exact compatibility by compressor serial number, so confirm the fitment through an authorized parts channel before ordering.

The 1616740990 is built as a continuous-duty module. The housing casting carries the mounting pads for direct installation onto the compressor frame, and the rotor set uses an asymmetric profile matched to this frame size and to the design pressure range of the OIS M-08 module. A surface treatment on the rotor profiles and the housing bore protects the running clearances through the air end s design life.

How the 1616740990 Air End Works

Oil-Injected Compression Cycle

The compression cycle inside the 1616740990 air end follows the positive-displacement rotary screw principle. Atmospheric air enters the compression chamber through the inlet port. As the male rotor turns, the lobe traps a fixed volume of air between the rotor groove and the housing bore. The trapped volume travels axially along the rotor profile. Simultaneously, the meshing action of the male and female rotors reduces this volume. The compression ratio develops continuously along the rotor length. At the discharge end, the compressed air exits through the outlet port at the design working pressure.

Oil injection occurs directly into the compression chamber. An oil gallery inside the housing delivers lubricant to the rotor mesh zone near the inlet side. Atomized oil disperses throughout the trapped air volume. The oil seals the running clearance between the rotor lobes. Clearance sealing prevents blowback of high-pressure air to the inlet side of the rotors. Without this oil seal, internal leakage would reduce the volumetric efficiency of the compression cycle.

Oil also absorbs compression heat. The temperature of the compressed air-oil mixture at the discharge port stays below the thermal limit of the rotor coating and bearing materials. Downstream oil separation removes the oil from the compressed air stream. The separated oil returns to the compressor s oil cooler and injection circuit. This closed-loop oil system operates continuously during loaded running conditions.

Rotor Timing and Bearing Arrangement

The male and female rotors inside the 1616740990 do not make direct contact. Timing gears mounted on the rotor shafts maintain the prec
