Air Preparation, Filtration and Pressure Regulation for Pneumatic Systems
Bellofram Precision Controls offers a versatile range of filters, regulators, and lubricators (FRLs) designed to prepare compressed air, control downstream pressure, and support reliable operation of pneumatic equipment. Available products include modular FRL assemblies, standalone air regulators, filter-regulators, stainless steel particulate filters, high-pressure air filters, and inline filtration solutions.
Bellofram modular FRL systems combine filtration, pressure regulation, and lubrication in compact air-preparation assemblies. Their modular design helps reduce the number of fittings required between components while allowing individual functions to be selected to match the needs of the pneumatic system. Multiple port sizes, pressure ranges, flow capacities, and filtration levels are available for applications ranging from compact machinery to higher-flow industrial equipment.
For applications requiring specialized filtration or materials, Bellofram also offers stainless steel filters and filter-regulators, high-pressure filtration, and inline filter assemblies. This range gives engineers options for protecting pneumatic instruments, actuators, valves, tools, machinery, and other downstream equipment from contamination and improper air pressure.
Why Choose Bellofram Filters, Regulators and Lubricators?
Compressed Air Filtration: Bellofram filtration options help remove particulate contamination from compressed air before it reaches downstream pneumatic components. Selected FRL configurations are available with multiple filtration grades to accommodate different air-quality requirements.
Stable Pressure Regulation: Bellofram air regulators are designed to reduce incoming pressure and maintain controlled downstream pressure as pneumatic system conditions change. Available configurations cover a range of pressure and flow requirements.
Controlled Lubrication: Lubricator configurations introduce a controlled amount of lubricant into the compressed-air stream for pneumatic equipment that requires downstream lubrication. Adjustable drip rates allow lubrication to be matched to the application.
Modular Air Preparation: Bellofram FRL components are designed for modular installation, helping reduce connection requirements and simplify the configuration of filtration, regulation, and lubrication functions.
Wide Range of Sizes and Flow Capacities: FRL and regulator configurations are available in multiple NPT port sizes and flow ranges, allowing air-preparation equipment to be matched to compact pneumatic systems as well as larger industrial applications.
Specialized Filtration Options: The Bellofram air-preparation range includes standard FRL filtration as well as stainless steel particulate filters, stainless steel filter-regulators, high-pressure filters, and inline filter assemblies for specialized system requirements.
Compressed Air Preparation for Industrial Applications
Proper compressed-air preparation can help protect pneumatic components from contamination, maintain the required operating pressure, and provide lubrication where the downstream equipment requires it. Bellofram filters, regulators, lubricators, and combination FRL units are suited for applications including pneumatic systems, industrial tooling, automation equipment, machinery, instrumentation, actuators, and process-control equipment.
Specialized stainless steel filtration and regulation options are also available for applications where corrosion resistance, clean gas handling, or specific material requirements are important.
Find the Right Filter, Regulator or Lubricator
Selecting the right compressed air filter, pressure regulator, lubricator, or FRL assembly depends on the requirements of the complete pneumatic system. Important considerations include inlet pressure, required outlet pressure, flow demand, port size, filtration level, drain requirements, lubrication requirements, operating temperature, media, and materials of construction.

Filters, Regulators and Lubricators FAQs
What does FRL stand for in a pneumatic system?
FRL stands for Filter, Regulator, and Lubricator. A filter removes contaminants from the compressed-air supply, a regulator controls downstream air pressure, and a lubricator introduces a controlled amount of lubricant for pneumatic equipment that requires it.
What does an FRL unit do?
An FRL unit prepares compressed air before it reaches downstream pneumatic equipment. Depending on the configuration, it can filter contaminants, reduce and control air pressure, and provide lubrication for components that require lubricated compressed air.
Does every pneumatic system need a filter, regulator, and lubricator?
Not necessarily. The required air-preparation components depend on the equipment and application. Most systems benefit from appropriate filtration and pressure regulation, while lubrication should only be added when the downstream pneumatic components are designed to operate with lubricated air.
What is the difference between a filter-regulator and an FRL?
A filter-regulator combines compressed-air filtration and pressure regulation in one assembly. An FRL adds a lubricator to the air-preparation system when downstream pneumatic equipment requires controlled lubrication. Bellofram offers both combination systems and individual air-preparation components.
How do I choose the correct pneumatic filter micron rating?
The appropriate filtration level depends on the air-quality requirements of the downstream equipment. Finer filtration can capture smaller contaminants, but filter selection should also account for required flow capacity, allowable pressure drop, system pressure, and the recommendations of the equipment manufacturer.
Can Bellofram FRL components be used in high-flow pneumatic systems?
Bellofram FRL systems are available in multiple port sizes and flow capacities for a range of pneumatic applications. The appropriate size should be selected according to required airflow, inlet and outlet pressure, port size, and the pressure-drop requirements of the system.
Does Bellofram offer stainless steel filters and filter-regulators?
Yes. Bellofram offers stainless steel filtration products including the Type 64SS particulate filter and Type 66SS filter-regulator. These products provide options for applications requiring corrosion-resistant materials or specialized air and gas filtration.
What is a high-pressure air filter?
A high-pressure air filter is designed to remove contaminants from compressed-air or gas systems operating at pressures beyond those typically handled by general-purpose FRL equipment. Filter pressure rating, element size, materials, port size, and media compatibility should all be considered when selecting a high-pressure filter.
How do I select the right FRL system?
FRL selection should consider inlet pressure, required outlet pressure, airflow, port size, filtration level, drain type, lubrication requirements, operating temperature, media, available installation space, and the requirements of the downstream pneumatic equipment.
