Correct compressed air preparation is essential for optimum performance of your pneumatic ring-main and equipment. IMI Norgren are experts in the FRL arena, where our ranges have been at the forefront of industry for many years. Our product ranges, including Olympian Plus and Excelon Plus, are available from individual to combination units.
IMI Norgren box sets offer an ideal solution as they come pre-assembled with filter/regulator, lubricator, shut-off valve, pressure gauge, and mounting brackets, ensuring quick and easy installation.
The IMI Norgren filter-regulator unit is our most popular standalone compressed air preparation unit. The filter-regulator combines precise pressure adjustment with removal of large amounts of water (moisture) and solid contaminants in a single unit, with 5 or 40 micron filtration grades.
General purpose filters remove water droplets and solid contaminants with 5 or 40 micron filtration grades. Oil removal filters provide filtration of oil droplets and fine particles down to 0.01 micron.
Our range includes general purpose pressure regulators, high-flow pressure regulators, pilot-operated pressure regulators, and special-purpose pressure regulator solutions, ensuring the right choice for every industrial and automation application.
Our range includes two types of pneumatic lubricators to suit different application requirements. Standard oil-fog lubricators are designed for heavy-duty, high air consumption applications, while micro-fog lubricators are ideal for long pipelines and complex, precision pneumatic circuits.
Pressure relief valves protect compressed air systems by preventing overpressure, thereby enhancing personal safety and equipment reliability. These valves automatically release excess pressure when the operating value exceeds the set limit.
The electrically operated version, known as a dump valve, isolates the main air pressure and safely exhausts residual pressure from the system, similar to the manual version. The soft start dump valve extends this function with a controlled restart that gradually builds up pressure in the system, reducing the risk of sudden movements and machine damage. Both standard dump valves and soft start dump valves are available with pneumatic (pilot-operated) actuation, allowing flexible integration into various industrial and automation applications.
The comprehensive range of accessories, including mounting brackets and connecting clamps, allows you to select the most suitable solution for your specific application requirements.
Our repair kits contain all the necessary parts for maintenance and servicing of compressed air preparation units.
Stainless steel compressed air preparation units provide outstanding corrosion resistance for applications where environmental conditions or media composition require it. When special materials are needed, our stainless steel product range offers a reliable solution, often meeting NACE MR-0175/2002 standard requirements. These units are excellently suited for harsh industrial environments where long service life and operational reliability are paramount.
Compressed air from the compressor contains contaminants (dust, water, oil) that damage pneumatic equipment and reduce their lifespan. The air preparation unit (FRL: Filter-Regulator-Lubricator) filters contaminants and stabilizes pressure — significantly extending the lifespan of pneumatic devices.
The FRL (Filter-Regulator-Lubricator) consists of three units: the filter removes dust and water droplets, the regulator stabilises working pressure within the rated supply range, and the lubricator supplies the air with fine oil mist. Important: most modern pneumatic devices have pre-lubricated, low-friction seals — additional air-line lubrication is not always required. Always check the manufacturer's specifications before applying a lubricator — oil is explicitly to be avoided in some applications (e.g., food industry and cleanroom environments).
Replacement frequency depends on the environment and usage intensity. General guideline: replace the filter element when the differential pressure across the filter exceeds 0.2-0.3 bar — greater pressure drop results in significant energy loss. Automatic drain is recommended for condensate removal. NorTrade air preparation units include visual condition indicators to help plan maintenance.
For FAD (Free Air Delivery) planning, add up the air consumption of all simultaneously operating devices, then add a 20-30% reserve for peak demands and leakage losses. In system design, the length and diameter of the piping network also affects the required capacity. NorTrade engineers perform system design calculations for your application — request a quote.
When designing and operating pneumatic systems in the EU, the following standards apply: ISO 4414 (general pneumatic safety requirements), EN ISO 13849 (safety controls within machines), and compliance with the 2006/42/EC Machinery Directive. Key principles: the system must always be depressurized before maintenance, maximum operating pressure is determined by the weakest component, and the pressure rating of pipes/hoses must be regularly inspected.
According to the lockout/tagout (LOTO) procedure: shut off the air supply at the main valve, then release residual pressure from the system through the exhaust valve. Verify with a pressure gauge that the pressure is truly zero, and only then perform any work. Never work on a pressurized system.
