ZW400A-90/2-HB006 Model Oil-Free Compressor Motor Analysis Report

Device Identification and Areas of Use

The product examined in the visuals is a dual-head, piston-mechanism, oil-free type air compressor or vacuum pump motor block. The product is a single piece and is in the form of a “bare motor/pump” unit, not mounted in any casing. It is generally used as a spare part or main component in the following areas:

• In dental units (as a dental compressor motor).
• In oxygen concentrators.
• In ozone generators or similar medical/industrial air systems.
• In automation systems requiring a silent air source.

Brand and Model Information

The product body and its labels have been examined in detail, and the identifying data are as follows:

• Brand: There is no prominent brand name written as text on the product. A spiral-shaped logo embossment is present on the cylinder heads, but this logo does not directly represent a brand name as text. Therefore, the brand has been evaluated as “Unspecified OEM Production”.
• Model: The code ZW400A-90/2-HB006 is clearly readable opposite the “MODEL” inscription on the label.

Technical Specifications and Label Data

The technical specifications on the black label on the main body of the product are as follows:

• Voltage and Frequency: 220V AC, 50Hz
• Capacitor Value: 10µF (The capacitor value required for the motor to operate is specified)
• Power Consumption: 480W
• Current: 2.2A
• Protection Class: Thermally Protected Class B (Thermally protected)
• Warnings: “DO NOT LUBRICATE” (Confirms oil-free operation), “WARNING: HOT SURFACE”
• Certifications: CE Mark, ISO 9001-2008 quality standard, LVD 10-4100
• Cable Color Codes: Schematically represented as BLUE, BROWN, BLACK.

Physical Condition and Cosmetic Examination

The cosmetic condition and material structure of the device have been analyzed based on the visuals as follows:

• Body Material: Cylinder heads and cooling blocks are made of cast aluminum. The middle body of the motor is a black metal structure.
• Overall Cosmetic Condition: The product generally appears clean. No rust, serious corrosion, or dents that would hinder usage have been detected on the body.
• Deformation: There are no noticeable deep scratches or impact marks on the metal parts. The cast aluminum parts are in solid form.
• Dust and Dirt: There is some light dust on the device, possibly due to shelf/storage, but no heavy oil or dirt accumulation is visible.

Mechanical and Electronic Component Analysis

Based on the data obtained from the visuals, the condition of the mechanical and electronic parts is:

• Cooling System: A cooling fan is visible at the back of the device (visual 2). No broken or missing fan blades have been observed. The heat-dissipating metal fins on the cylinder are intact.
• Connection Elements: An ‘L’-shaped (elbow) air outlet fitting made of yellow brass material is attached to the right cylinder head. A black plug/plastic piece is visible at the left cylinder outlet.
• Mounting Feet: The 4 mounting holes (feet) on the base of the device, where vibration isolators are to be fitted, are intact; there are no breaks.
• Cabling: The motor’s electrical connection cable is white, enclosed in a braided sleeve (glass fiber sleeving) presumed to be heat-resistant. The cable exit point from the motor body is secured with yellow tape. There is no plug, socket, or terminal at the cable end; the cables are bare-ended, ready for installation.

Other Label and Tracking Information

In addition to the main label, the following identifying codes have been detected on the product:

• Top Barcode Label: A white barcode label containing the number 160419D664 is located on the top part of the motor block. This number could be a production series or lot number.
• Main Label Barcode: A long barcode is located directly below the model information.

Missing Parts and Accessories

Although the product appears to be complete, the following parts required for a full system setup were found to be missing from the visuals:

• Muffler/Filter: Air filters/mufflers, which should be attached to the air intake ports, are not visible in the visuals.
• Capacitor: A 10µF capacitor value is specified on the label. An external capacitor (run or box type) is not visible in the visuals. Whether it is internal under the motor cover cannot be confirmed from the visuals, but in motors of this type, it is usually connected externally.
• Vibration Isolators: The mounting feet are empty; rubber anti-vibration isolators are not visible in the visuals.

Potential Failure Risk and General Assessment

Overall Condition: Visually, the device is in high condition and gives the impression of being “New” or “Very Lightly Used”. The shininess of the screws and the cleanliness of the motor windings (copper parts visible through the cooling fins) indicate that the device has not been operated under harsh conditions for an extended period.

Risks: No mechanical or electrical failures (burn marks, cracked casing, broken cable roots, etc.) have been detected in the visual analysis. There is only a slight opening/fraying on the outer sheath of the cable end (at the cable tip), which is an insignificant detail as a connection will be made.
