AEG 140CFA04000
Product Name: Hermetic Reciprocating Compressor
Model Series: 140CFA Series — Refrigeration Compressor
Applicable Products: AEG Refrigerators, Freezers, Wine Coolers, Built-in Cooling Appliances
Product Description:
The AEG 140CFA04000 is a hermetic reciprocating compressor used in AEG and Electrolux household refrigeration appliances. It is a R600a (isobutane) eco-friendly refrigerant compressor designed for high energy efficiency (A++/A+++ rated appliances). It provides the mechanical compression cycle that drives the vapor-compression refrigeration system.
Detailed content
Technical Specifications:
- Part Number: 140CFA04000
- Compressor Type: Hermetic reciprocating, single cylinder
- Refrigerant: R600a (Isobutane) — 40g – 60g charge

- Weight: 8.5 – 11.0 kg
- Insulation Class: Class F (155°C)
Materials:
- Shell: Welded steel (DC04 cold-rolled steel)
- Cylinder: Cast iron or aluminum alloy
- Valves: Spring steel (SUS302) with PEEK reed valve plates
- Crankshaft/Connecting Rod: Carbon steel, nitrided surface
- Motor Windings: Copper, Class F enamel insulation
Working Principle:
The compressor operates on the vapor-compression cycle: low-pressure refrigerant gas enters the suction port → piston compresses the gas → high-pressure gas exits through the discharge valve → gas flows to the condenser → after heat rejection, liquid refrigerant passes through the expansion valve → evaporator absorbs heat from the cabinet → low-pressure gas returns to compressor suction.
Advantages:
- Ultra-low noise — optimized crankshaft balance and rubber mounting
- R600a refrigerant — zero ODP, GWP = 3 (environmentally superior to R134a)
- High COP (Coefficient of Performance) — contributes to A+++ energy rating
- Long service life — hermetic seal prevents refrigerant leakage
Installation Requirements:
- Must be installed in a well-ventilated compartment (minimum 10L air space around compressor)
- Vibration isolators mandatory — use original rubber mounts
- Electrical connection via PTC starter + thermal overload protector
- Refrigerant circuit must be evacuated and charged by certified technician
