Philips Respironics EverFlo Oxygen Concentrator Analysis Report

Device Identification

The device in the examined images is a stationary oxygen concentrator used for medical purposes. The product is a medical device that takes in room air, separates it, and provides concentrated oxygen to the patient. Its body structure is vertically positioned, with a compact design featuring wheels at the bottom for easy portability and a handle at the top.

Brand and Model

Upon examining the logo print on the front face of the device and the detailed product label on its back panel, its brand has been clearly identified as Philips Respironics. The model information is stated on the back label in white text on a black background as EverFlo | OPI. Additionally, the inscription “EverFlo” can be read, albeit faintly, on the lower part of the front face. The product is a 5-liter capacity oxygen device known for its reliability in medical literature.

Originality

The quality of craftsmanship in the product’s plastic casing, the smoothness of mold marks, the correct font and placement of the Philips Respironics logo, and the compliance of the back panel label with industrial standards (barcode, CE mark, clarity of symbols) indicate that the device is 100% original. Furthermore, the Velcro details on the humidifier bottle holder strap and the design of the flowmeter carry the characteristic features of the brand.

Areas of Use

This device is designed for patients suffering from respiratory failure, such as COPD (Chronic Obstructive Pulmonary Disease) and pulmonary fibrosis, who require long-term oxygen therapy at home. It separates oxygen from ambient air and delivers it to the patient via a nasal cannula or mask. It is a stationary device and operates on electricity; therefore, it is suitable for use at the patient’s bedside or within a room.

Quantity Information

The images show 1 Philips Respironics EverFlo main unit, 1 humidifier water bottle and its hose attached to the device, 1 power cable integrated into the device, and 1 air inlet filter cover/sponge shown detached. No other external accessories are visible.

General Condition

The external cosmetic condition of the device generally appears clean and well-maintained. Although it is a second-hand (used) product, there is no significant fading in the blue plastic body color. The device maintains its integrity, and there are no signs of misuse.

Physical Deformation

A detailed examination of the product’s outer casing revealed no breaks, cracks, dents, or deep scratches. The front panel, side covers, and rear grille sections appear solid. No impact-related compressions are visible at the corners.

Mechanical Components

The 4 swivel wheels that enable the device’s movement are intact and in place. The flowmeter (debimetre) knob, which adjusts the flow, appears solid in the image and shows no signs of mechanical damage. The tabs of the filter compartment cover on the back panel are intact; one of the images shows the cover being held by hand and easily removable. The rear strap (Velcro) holding the humidifier bottle is present.

Electronic Components

Electronic circuits (internal motherboard, etc.) of the device are not visible in the visual inspection. However, the black “On/Off” power switch on the front panel is physically in place. The power cable emerges from the lower rear part of the device, and no visible crimping, breakage, or fraying has been detected in the cable in the image.

Accessories

One humidifier bottle is attached to the device. This bottle ensures that oxygen is humidified before being delivered to the patient, preventing dryness. Additionally, the 4th image shows the device’s rear air inlet filter (sponge type). The filter cover and sponge are present. A cannula (hose going to the patient) is not present in the images; only the bottle and its connecting hose are visible.

Label Information

The information on the technical label on the back of the device is as follows:

• Reference Number (REF): 1020006
• Serial Number (SN): 2234877
• Input Power: 230V ~ 50 Hz, 1.5 Amperes (Compatible with Turkish and European grid standards)
• Oxygen Output Purity: Max O2: 96%
• Weight: 14-15 kg
• Protection Class: IP21 (Protected against vertically falling water drops)
• Origin: Made in Mexico (Mexican production)
• Manufacturer Address: Respironics Inc. Murrysville, PA, USA
• Barcode (GTIN/UDI equivalent): (01)00606959032552

Display Analysis and Controls

This model does not feature a digital display. An analog “Flowmeter” is present, indicating the oxygen level. The black ball inside the flow tube moves up and down when the adjustment knob is turned. The scale ranges from 0 to 5 LPM (Liters/Minute). In the setting shown in the image, the black ball is at the very bottom (at the 0 mark), meaning the device is not dispensing gas while operating or is in the off position.

Size and Compatibility

The device is of standard size for home use. The label indicates its weight as 14-15 kg. Due to its 5 Liters/Minute capacity, it is generally used for adult patients, but with appropriate flow settings, it can also be considered for pediatric use under medical supervision.

Year of Manufacture

There is no clear “Date of Manufacture” directly on the label. It may typically be encoded within the serial number, but a definitive year cannot be determined from the images.

Documents

No paper or documents related to an invoice, warranty certificate, or user manual are present in the images.

Current Fault

Since no “broken parts,” “burn marks,” or physical damage are visible in the images, there is no detectable, permanent fault. The flowmeter tube is intact.

Potential Fault Risk

The device’s air inlet filter (gray sponge) is being held by hand. The color of this sponge appears dark gray, which may indicate dust accumulation due to use. Failure to clean this filter could lead to the device overheating or operating loudly. Since the device’s power cable is gathered at the bottom, there is a risk of it getting caught under the wheels and being crushed, but in the current image, the cable is intact.
