The WAALPC A/B Series represents a comprehensive family of air source treatment components designed for industrial pneumatic systems. This modular product line includes individual components — pressure regulators, filters, filter-regulators, and lubricators — as well as pre-assembled F.R.L Two Units and F.R.L Three Units. Each product is engineered to deliver reliable performance, precise control, and long service life in demanding manufacturing environments.
This guide provides a complete technical overview of the A/B Series, covering each product category with detailed specifications, working principles, key features, and application scenarios.
In pneumatic systems, maintaining a stable and precise air pressure is crucial for the consistent performance and longevity of downstream components such as cylinders, valves, and actuators. Fluctuations in the supply pressure can lead to inconsistent operation, reduced efficiency, and even equipment damage. The WAALPC AR Series pressure regulators are designed to address this challenge, providing reliable and precise pressure control for a wide range of industrial applications.
The AR Series, including models AR1500 and AR2000, is part of WAALPC‘s A/B Series of air source treatment components. These regulators are engineered to deliver stable output pressure regardless of variations in the inlet pressure, ensuring your pneumatic system operates at peak performance. Each regulator is equipped with a pressure gauge port for easy monitoring of output pressure.
The AR Series regulators operate on the diaphragm force-balance principle — a tried-and-tested mechanism used in countless pneumatic systems for its reliability and accuracy.
Pressure Setting: Turning the adjustment knob compresses a set spring, which applies a downward force on a diaphragm.
Valve Operation: This force pushes a valve stem, opening the valve port and allowing compressed air to flow from the inlet to the outlet.
Pressure Feedback: The outlet pressure is channeled back to the underside of the diaphragm, creating an upward force that opposes the spring force.
Dynamic Balance: The valve automatically adjusts its opening to maintain a balance between the spring force and the outlet pressure. If the outlet pressure drops, the valve opens wider; if it rises, the valve closes slightly, ensuring a constant output pressure.
Light and Compact Structure: The AR Series features a lightweight, die-cast aluminum housing that simplifies installation and saves valuable space in your equipment.
Press-in Self-locking Mechanism: Prevents the set pressure from being accidentally altered due to external interference or vibration, ensuring consistent system operation.
Low Pressure Loss: The internal design minimizes pressure drop, ensuring efficient use of your compressed air supply.
High Efficiency Water Separation: The integrated water separator effectively removes condensate from the air stream, protecting downstream components from moisture damage.
Pressure Gauge Port: Each regulator is equipped with a pressure gauge port for convenient monitoring of output pressure.
Versatile Configurations: In addition to the standard type (0.05–0.85 MPa), a low-pressure type with a maximum regulating pressure of 0.02–0.83 MPa is also available for applications requiring finer control at lower pressures.

Clean, dry air is the lifeblood of any pneumatic system. Moisture, dust, and oil aerosols are the primary culprits behind premature wear, corrosion, and malfunction of valves, cylinders, and other components. The WAALPC AF Series filters are the first line of defense, designed to remove these harmful contaminants from your compressed air supply.
The AF1500 and AF2000 filters provide a highly effective solution for ensuring air quality, thereby extending the service life and reliability of your entire pneumatic system.
The AF Series filters use a combination of mechanical separation and filtration to purify compressed air:
Centrifugal Separation: Incoming air is directed into the filter bowl tangentially, creating a high-speed spinning motion. This centrifugal force throws heavier water droplets and larger solid particles against the bowl‘s inner wall, where they collect at the bottom.
Filtration: After the initial separation, the air passes through a filter element. This element traps finer particles, including dust, rust, and oil aerosols. WAALPC offers filter elements in 5μm, 25μm, and 40μm grades to meet varying levels of required air purity.
Condensate Drainage: The collected water and contaminants are removed from the system via a drain valve. The bowl is transparent, allowing for easy visual inspection of the condensate level.
Efficient Contaminant Removal: Effectively removes moisture, oil, and solid particles, safeguarding your equipment.
Multiple Filtration Grades: Choose from 5μm, 25μm, or 40μm elements to match your application‘s cleanliness requirements.
Transparent Bowl: The clear bowl design allows for easy, at-a-glance monitoring of the filter element’s condition and the level of collected condensate.
Compact and Lightweight: The die-cast aluminum housing ensures a robust yet compact design, making it easy to install in tight spaces.
Reliable Performance: Designed for continuous operation, the AF Series provides consistent air quality to protect your downstream equipment.

While filtration and regulation ensure clean, stable air, many pneumatic components require lubrication to minimize friction, reduce wear, and ensure smooth operation. The WAALPC AL Series oil mist lubricators provide this essential function by introducing a controlled amount of atomized oil into the compressed air stream.
The AL1500 and AL2000 lubricators are designed to deliver a precise oil mist to downstream tools, cylinders, and valves, significantly extending their operational life.
The AL Series operates on the Venturi (aspiration) principle — a simple yet highly effective method for oil atomization:
Pressure Drop: Compressed air passes through a nozzle in the lubricator, creating a high-velocity air stream and a localized pressure drop.
Oil Lift: This pressure drop creates a suction effect that draws oil from the reservoir through a pickup tube.
Oil Atomization: The oil is then metered by an adjustable needle valve and introduced into the high-velocity air stream, where it is sheared into a fine mist.
Delivery: The resulting oil mist is carried by the compressed air downstream, where it lubricates moving parts.
Effective Lubrication: Provides a consistent oil mist, reducing friction and wear on downstream pneumatic components.
Adjustable Oil Feed: A needle valve allows you to precisely control the oil droplet rate, ensuring the right amount of lubrication for your specific application.
Transparent Bowl: The clear oil reservoir allows for easy monitoring of the oil level, preventing dry operation.
Recommended Oil: For optimal performance and longevity, WAALPC recommends using ISO VG32 or equivalent oil.
