Filters General Overview Three main types of filters exist: The general purpose filter for water and particles, the coalescing oil removal filter for oil aerosols and the activated carbon filter for the removal of oil vapors. The general purpose filter is used for most filter applications and is available from 1/8" to 2" pipe sizes. Uses are main headers, branch lines, tools, cylinders, valves and valve circuits, air agitators etc. Oil removal filters are used where very clean, oil-free air is required, such as for the supply to instrumentation, air gauging equipment and air bearings....

Filter Information Simple Filter Troubleshooting Malfunction Possible Cause Remedy Excessive pressure drop Micron rating of element too small Use larger micron element size for application. Filter element blocked 1.Clean element (not coalescing element). 2.Replace with new element. Flow requirement greater than filter capacity. Drain water Maintain flow within capacity of filter or change to filter capable of handling desired flows. Bowl has been cleaned with incompatible fluid Replace bowl (Clean only with clean warm water and soap.) Replace bowl Eliminate source of problem or convert from...

Regulators General Overview Regulators ideally provide a constant outlet pressure independent of variations in inlet pressure or flow. Regulators are typically used to: a) reduce pressure to the level required for downstream equipment b) limit the force of cylinders c) minimize pressure variation at the point of use The range of different regulators and options within each type are wide and varied, but each can broadly be put into one of 3 categories. • general purpose regulators • pilot operated regulators • application specific regulators General Purpose Regulator Knob Adjusting screw...

Regulator Information Simple Regulator Troubleshooting Problem Problem cause Remedy Regulator creep (increase in secondary pressure due to leak from primary) Dirty or cut valve elastomers. Nick in valve seat. Replace or clean valve. If body or valve seat is damaged it can be replaced on some models. On others replacement of complete regulator is required. Won’t relieve secondary pressure Non-relieving diaphragm assembly. If this feature is required, replace with relieving type diaphragm assembly. Won’t reach desired pressure Regulating spring with low spring rate. Use regulating spring with...

Filter/Regulator General Overview Filter/regulators combine the features of a filter and regulator with a single compact body. Air passes through the filter section first removing water and particle contaminants, and is then regulated by the top regulator section. See individual filter and regulator sections for details. General Purpose Filter/Regulator Knob Adjusting screw Adjusting nut Control spring Spring rest Relief seat Diaphragm Valve pin Valve Valve spring Center post Bowl Performance characteristics: The regulator section of the filter/regulator determines the flow and regulation...

Information Lubricator General Overview Dixon offers two main types of lubricators: Micro-Fog and Oil-Fog. These units are mounted directly into the pipe and add small amounts of oil to the air flowing through them. Micro-Fog Lubricator Sight dome Micro-Fog Lubricators: The oil droplets seen in the sight dome are atomized and collected in the area above the oil in the bowl. The smaller lighter particles are drawn into the air flow and pass downstream. As a result typically only 10% of the oil seen as drops in the sight dome is passed downstream. The remainder falls back into the oil...

What Are The Differences Between Micro-Fog and Oil-Fog? Micro-Fog: • Small oil particles; less than 2 micron • Only 10% of ‘drip rate’ is delivered downstream as active lubricant (remainder is returned to main oil reservoir) • High drip rates make drip setting easier in low flow applications • Can be mounted above or below the point of application • Cannot be filled without shutting off upstream air (unless a quick fill cap or remote fill device is used) • For use with lengthy air lines, multiple valve and cylinder circuits • Has a flow sensor to provide an almost constant oil output...

Lubricator Information Filling Methods Micro-Fog: The standard micro-fog unit can only be filled without isolating the upstream pressure if a remote fill or quick fill nipple accessory is fitted. To remove the fill plug of a micro-fog lubricator while under pressure can be dangerous. If in doubt shut off the upstream air! Oil-Fog: The standard oil-fog lubricators can be filled under pressure, for example without switching off the upstream air. When a fill plug is removed a check valve in the lubricator body isolates the inlet pressure from the bowl and the reservoir will depressurize. The...
