Product overview
Power: 55 kW · AOF55 / AOFM55 examples · Flow: Delivery at agreed pressure / reference basis
AE's dry oil-free screw page separates AOF standard, AOFM and low-pressure AOFML families. It describes stainless-steel rotors, a labyrinth/dust-seal arrangement and PLC monitoring/protection. The original AOF-branded enclosure image identifies the range; it does not define the model or certificate scope of an order.
At 55 kW, AOF55A/W lists 1,750 kg for A and 1,950 kg for W. AOFM55A/W separately lists 1,650 kg and 1,850 kg. Both give 2,650 × 1,550 × 2,000 mm for A and 2,500 × 1,550 × 1,850 mm for W, with DN65. Confirm the selected variant's cooling/utility requirements, current approved drawing and maintenance space.
The current pressure-table heading and numerical units need confirmation on a signed model datasheet. Agree delivery and package input at explicit pressure/reference conditions. Do not substitute AOFML low-pressure figures or another variant's duty. Set oil, particle and moisture limits at the users and obtain applicable model-specific air-quality and test documents.
Drying, filtration, receiver, drainage and distribution remain part of the system design. Specify the equipment list, manuals and consumables, commissioning and destination service. A general manufacturer Class 0 statement must not be represented as a current certificate covering every model.

Specifying a Oil-free duty
| Duty | Write on the RFQ |
|---|---|
| Oil-free screw compressor manufacturers in China | Oil-free screw is a different factory from oil-injected screw. Dry airends and water-lubricated airends are also different quotes. Name the architecture. |
| Compressor for a food factory | Food air is a validation file. Class, test point and treatment matter as much as kW. A general 8 bar screw without papers is not a food quote. |
| Compressor for a pharmaceutical plant | Pharma procurement is a document pack: IQ/OQ support, material certs, residual oil. The machine is the easy part if the RFQ lists the papers. |
