HONG KONG – June 17, 2026 – Oxygen Express, a premier flagship retailer and trusted distributor of high-quality respiratory and sleep therapy equipment in Hong Kong, is proud to announce the availability of the highly anticipated DEVILBISS 525KS 5L Oxygen Concentrator. Manufactured in the United States by Drive DeVilbiss Healthcare, this state-of-the-art stationary oxygen concentrator is meticulously engineered to deliver continuous, reliable, and medical-grade oxygen therapy for home users. Recognizing the growing demand for effective home-based management of chronic conditions, Oxygen Express is highlighting this unit’s exceptional capabilities in providing clinical-grade respiratory support, ensuring that patients can maintain their independence, safety, and comfort within their own homes.
The Gold Standard in Home Respiratory Care
For individuals managing chronic respiratory conditions such as Chronic Obstructive Pulmonary Disease (COPD), pulmonary fibrosis, occupational lung diseases, or severe chronic asthma, having a dependable source of supplemental oxygen at home is not just a daily convenience—it is a critical, life-sustaining requirement. The DEVILBISS 525KS 5L Oxygen Concentrator represents the gold standard in stationary oxygen therapy. Delivering a continuous flow ranging from 0.5 to 5 liters per minute (Lpm), the device consistently provides an impressive high-purity oxygen concentration of 93% (+/- 3%) even at its maximum flow capacity. This unwavering performance ensures that patients receive the precise prescribed amount of oxygen required to maintain healthy blood oxygen saturation levels, thereby significantly improving their overall quality of life, cognitive function, energy levels, and daily mobility. Manufactured in the USA, the device carries a rich legacy of robust construction, rigorous quality control, and unparalleled durability that patients and healthcare providers worldwide have trusted for decades.
Whisper-Quiet Operation for Enhanced Quality of Life
One of the most common complaints among home oxygen users is the disruptive mechanical noise generated by traditional concentrators, which can heavily interfere with sleep, conversation, and daily relaxation. Addressing this critical pain point directly, the DEVILBISS 525KS 5L Oxygen Concentrator features an advanced, acoustically engineered design that dramatically reduces operational noise. Emitting a mere 40 decibels (dBA)—comparable to the hushed ambient sounds of a quiet library—the device operates unobtrusively in the background. This whisper-quiet performance ensures that users and their families can sleep peacefully through the night without being disturbed by loud humming or vibrations. Good quality sleep is essential for the recovery and immune function of respiratory patients, making the acoustic profile of this machine a vital component of its therapeutic value.
Energy Efficiency and Sustainable Long-Term Use
In addition to its low noise levels, the unit is highly energy-efficient, consuming approximately 290 watts at a flow rate of 2 liters per minute and approximately 312 watts at its maximum output of 5 liters per minute. This optimized power consumption helps households manage their electricity bills effectively, even when the concentrator is required to run continuously around the clock. By minimizing energy wastage, Drive DeVilbiss has created a machine that supports long-term adherence to prescribed oxygen therapy regimens without placing an undue financial burden on families. This economic viability makes it an ideal choice for patients who depend on long-term oxygen therapy (LTOT) to manage their daily health.
Advanced Safety Features with Oxygen Purity Indicator (OPI)
Patient safety remains the paramount concern in any medical device, and this model excels in this area with its integrated Oxygen Purity Indicator (OPI). The OPI is an intelligent, built-in monitoring system that continuously evaluates the oxygen output concentration using ultrasonic technology. If the oxygen levels ever drop below clinically acceptable therapeutic parameters, the OPI system immediately triggers distinct visual and audible alarms to alert the user or caregiver. This proactive safety feature provides unparalleled peace of mind, assuring users that they are always receiving the exact therapeutic levels of oxygen they require without second-guessing the machine’s performance. It eliminates the anxiety associated with potential mechanical degradation, providing a fail-safe environment for home care.
Ergonomic Design and Seamless Mobility Within the Home
Despite its robust clinical performance, the DEVILBISS 525KS 5L Oxygen Concentrator is designed thoughtfully with the user’s home environment in mind. The unit features a sleek, compact footprint, measuring 62.2 cm in height, 34.2 cm in width, and 30.4 cm in depth. Weighing 16.3 kilograms, the system is housed in a highly durable, flame-retardant cabinet for maximum protection. To facilitate effortless movement between rooms—whether transitioning from the bedroom for sleep to the living room for daytime activities—the device is equipped with smooth-gliding caster wheels and a sturdy, ergonomic top handle, eliminating the need for heavy lifting and ensuring that patients can move their oxygen supply with minimal physical exertion.
Empowering Post-Discharge Recovery and Elderly Care
The transition from hospital to home can be challenging for patients recovering from acute respiratory illnesses or major surgeries. The availability of a premium concentrator like the DeVilbiss 525KS facilitates a smoother transition, reducing the risk of re-hospitalization by providing a stable and clinical-grade recovery environment at home. Furthermore, for the elderly population experiencing age-related pulmonary decline, this device offers a reliable framework for daily therapy. By ensuring consistent oxygenation, it reduces the strain on the cardiovascular system and alleviates symptoms of chronic fatigue, thereby fostering a more active and fulfilling lifestyle for seniors.
Comprehensive Package and Exclusive Promotional Pricing
To make premium respiratory care more accessible to the local community, Oxygen Express is currently offering the DEVILBISS 525KS 5L Oxygen Concentrator at an exclusive promotional price of HK$9,500, significantly discounted from its standard retail price of HK$12,500.
