The PARKER-FINITE QU280-51 replacement filter element is a high-performance compressed air filtration solution engineered to meet demanding industrial standards. Designed as a direct alternative to the original QU280 series, this element delivers reliable particle and oil aerosol removal while maintaining exceptionally low pressure loss. Manufactured in Wuxi, Jiangsu, China, it combines precision engineering, stable materials, and strict quality control to ensure long service life and consistent filtration efficiency across diverse operating conditions.

As a professional replacement filter element manufacturer, WUXI Yuanmei focuses on compatibility, durability, and operational efficiency, offering users a dependable solution for compressed air systems where air purity and energy savings are critical.

Key Advantages

One of the most significant advantages of the QU280-51 replacement element lies in its optimized airflow design. With a pressure loss of ≤0.011 bar, the element minimizes energy consumption during operation, contributing to measurable system efficiency improvements of approximately 5–7%. This low resistance performance helps reduce compressor load and operational costs over time.

Another key advantage is its extended service life of up to 8,000 hours under standard working conditions. This longevity reduces replacement frequency, lowers maintenance costs, and minimizes downtime in continuous production environments.

Fast availability is also a practical benefit. Main models are stocked and can be shipped within 24 hours, making it suitable for urgent maintenance or unexpected system shutdowns. Combined with flexible MOQ requirements starting from just one piece, the product is accessible to both large-scale industrial users and smaller facilities.

Core Features

The QU280-51 replacement filter element is built with micro fiberglass filtration media, ensuring high particle capture efficiency while maintaining stable airflow. With a filtration precision of 0.01 μm and a residual oil content as low as 0.01 ppm, it meets strict compressed air quality requirements for sensitive industrial processes.

The element operates reliably within a working pressure range of 0.1 to 2.0 MPa and a temperature range from 1.5°C to 80°C, making it suitable for varied industrial environments. Engineering plastic end caps provide structural strength and corrosion resistance, while the Buna-N seal ensures secure sealing and prevents air bypass during operation.

Each unit is produced with manufacturing precision that ensures dimensional accuracy (78 ±1 mm diameter and 715 ±2 mm height), allowing seamless installation without modification. This precise fit guarantees compatibility with original PARKER-FINITE housings and stable long-term performance.

In addition, WUXI Yuanmei offers OEM drawing service, enabling customized specifications to match unique system requirements, private labeling, or special performance demands.

Diverse Applications

The QU280-51 replacement filter element is widely used in industries where clean, dry, and oil-free compressed air is essential. In laser cutting operations, it protects optical components and pneumatic controls from contamination, ensuring cutting accuracy and equipment longevity.

In the electronics industry, where even microscopic particles can affect product quality, the filter supports stable air purity for assembly lines, testing equipment, and cleanroom-related processes. Its low oil carryover performance is especially valuable in environments sensitive to hydrocarbon contamination.

Sandblasting and surface treatment applications also benefit from this filter element. By removing moisture, oil, and fine particulates, it helps maintain consistent blasting pressure, improves surface finish quality, and reduces nozzle wear.

Beyond these core uses, the element is suitable for general manufacturing, automation systems, and compressed air networks requiring ISO-level air cleanliness.

User Value & Benefits

From a user perspective, the QU280-51 replacement filter element delivers long-term operational value rather than short-term cost savings alone. Its low pressure loss directly translates into reduced energy consumption, which can significantly lower electricity expenses in compressed air systems operating continuously.

The extended service interval reduces maintenance workload and spare parts inventory requirements, allowing maintenance teams to focus on higher-value tasks. Stable filtration performance also minimizes the risk of downstream equipment damage, protecting investments in tools, actuators, and precision machinery.

Compliance with ISO8573-1, CE, and RoHS certification marks provides users with confidence in product safety, environmental compliance, and international applicability. These certifications make the filter suitable for export-oriented manufacturers and globally standardized production lines.

With flexible packaging options, including plastic bag, box, cartons, pallets, or custom solutions, logistics efficiency is further enhanced. Reliable supply capacity of over 1,000 pieces ensures continuity for long-term projects and repeat orders.

Overall, the PARKER-FINITE QU280-51 replacement filter element represents a balanced combination of performance stability, energy efficiency, and manufacturing reliability—making it a practical choice for users seeking a trustworthy alternative from an experienced replacement filter element manufacturer.
