GLOSSARY OF TERMS:

Coupler (Socket) - The female end of the coupling.  This part contains the sleeve by which the connect and disconnect action is controlled.

Plug - The male end of the coupling.  Often referred to as the nipple or male end.

Automatic Coupler - To connect the plug to the coupler, you merely push the plug into the coupler.

Semi-Automatic Coupler - Often referred to as a manual coupler.  The sleeve must be manually retracted in order to connect the plug.

Single Shut-off - When the disconnect is made, the air will be trapped on the coupler side only.  Any air contained by the plug end will escape to the atmosphere.

A short length whip hose is recommended on impact tools connected with these couplers
to prevent premature wear caused by excessive vibration.
 
"AIR CHIEF" SEMI-AUTOMATIC COUPLERS

How They Work :
Quick-connect couplers are generally accepted as the fastest, easiest and most reliable means of joining low pressure pneumatic lines.
Despite differences in outward appearance, nearly all quick-connect couplers work on the same principles:  Hardened balls or pins engage a groove in the coupler plug to hold it securely against a soft positive seal gasket.  This also permits the assembly to swivel, which helps to prevent kinking or twisting of the hose.  A sliding sleeve releases the locking balls when retracted, permitting the plug to be inserted or removed.  The sleeve automatically returns to the locked position when released.  An automatic shut-off valve in the coupler seals when being uncoupled, eliminating the need for a separate shut-off.



"AIR CHIEF" AUTOMATIC COUPLERS
Easy, one-hand operation:
These automatic, push-to-connect couplers mate with standard Industrial plugs.  Disconnecting can be accomplished with one hand, by pushing the sleeve forward toward the plug.  Available with corrosion resistant brass sockets.

Air King Hose End

          "Air King" Fittings

SERVICE - Dixon "Air King" couplings are recommended for use on air lines for virtually any type of pneumatic equipment.  The maximum recommended working pressure for Dixon "Air King" universal couplings is 110 PSI or less.  "AIR KING" FITTINGS ARE FOR AIR SERVICE ONLY!

FEATURES - Dixon "Air King" fittings have a universal head which is identical for all parts (hose ends, male NPT and female NPT) within the 1/4" to 1" range.  This enables any two fittings (1/4" to 1") to be directly connected regardless of hose shank or threaded size.

CONNECTION - Connections are made by pushing two heads together and turning one quarter turn in a clockwise direction.  When this is done and the heads have seated properly, the small holes through the flange on the side of each coupling head will line up.  An "Air King" Safety Clip should be inserted at this point to assure the "Air King" couplings will not become accidentally disconnected.  If a Safety Clip is not available, insert a cotter pin or wire type retainer through the holes.  The fitting is now ready to be put into service.

DISCONNECTION - Remove the safety clip, cotter pin or wire.  Press the heads firmly together and turn them counterclockwise.  The heads will then separate.  NEVER attempt to disconnect any hose while pressure is in the line.

INTERCHANGE - Although "Air King" couplings may interchange with other manufacturers' fittings, we do not recommend their use with other products.  Not all locking heads are made to the same standards as Dixon "Air King".  Use with other brands of fittings may create an unsafe condition, due to poor design or worn equipment.
 



Air King with Ferrule

          "Air King" With Ferrule

SERVICE - "AIR KING" FITTINGS ARE FOR AIR SERVICE ONLY!

Along with the service, features and ease of connection of the Dixon "Air King" fittings listed above, "Air King" couplings with interlocking carbon steel ferrule also have the standard "Air King" universal head. This enables any of the "Air King" with ferrule couplings to connect directly to any other "Air King" coupling within the 1/4" - 1" range.
The ferrule comes attached to the fitting for easy installation. The ferrules can be swaged or crimped depending on your coupling installation equipment. Swaging and crimping dimensions are available.

FRL Combo Units

          Filters, Regulators and Lubricators (FRL's)
                            (FRL Combination Units)

HOW FRL's WORK:

FILTERS

Filter Dia
Contaminants from the atmosphere (dust, moisture, pollutants) are drawn into the air system at the compressor intake. Sludge, oil and foreign matter may be added to the air system by the compressor itself. Such contaminant air can interfere with the operation of the air driven device, and, in time, damage it. Compressed air filters, installed upstream of the air driven device, remove these contaminants as well as most water condensate from the flowing compressed air.

Some applications require extremely clean air virtually free of oil aerosols. Oil removal (coalescing) and oil vapor removal filters are used in these applications.

General Purpose/Operation

Removes bulk liquids and solid particles down to 5 microns (depending on micron rating of element selected).
Used for most industrial applications (factory compressed air lines and machinery) and as a prefilter for the Oil Removal (Coalescing) Filter.

REGULATORS

Regulator Dia
Air driven devices are designed to work at a certain pressure. Most devices will operate at pressures in excess of that recommended. However, operating at higher pressures can cause excess torque, force and wear and can waste compressed air. The best operation and life of the device can be obtained by using the proper pressure level. A regulator is used to reduce and maintain the pressure at a level suitable for the device.

General Purpose/Operation

Outlet pressure is controlled by the adjusting knob. Clockwise rotation increases and counterclockwise rotation decreases the outlet pressure setting. When the knob is rotated fully counterclockwise, no force is applied to the regulating spring, and the valve is held closed by the valve spring. Clockwise rotation of the knob compresses the regulating spring, which applies a downward force on the top of the flexible diaphragm. The diaphragm and valve pin move downward forcing the valve off its seat, which allows air to flow past the valve to the downstream system.

FILTER / REGULATORS

Filter / Regulator Dia
A filter/regulator combines the functions of a filter and a regulator into one compact, space-saving unit.

General Purpose/Operation

Air entering the filter/regulator is guided into a swirling pattern by the louvres. Coarse solid particles and liquids are forced to the bowl wall by centrifugal force and drop to the bottom. The filter element removes most solid particles. A baffle creates a quiet zone at the bottom of the bowl and prevents air turbulence from picking up liquids and returning them to the air stream. An automatic drain dumps accumulated liquids.

An adjusting knob controls the outlet pressure setting; clockwise rotation increases and counterclockwise rotation decreases the outlet pressure setting. The regulating spring is compressed when the adjusting knob is rotated clockwise, which applies a downward force on top of the flexible diaphragm. The flexible diaphragm and valve pin move downward, forcing the valve off it's seat. Air flows past the valve to the downstream system. Pressure increases in the downstream system and in the sensing chamber and applies an increasing upward force on the bottom of the diaphragm.

The diaphragm, valve pin and valve move upward, compressing the regulating spring. Upward movement stops when the forces below the diaphragm balance the forces above the diaphragm. When there is no downstream flow demand, the balance of forces occurs with the valve closed. When there is downstream flow demand, the balance of forces occurs when the valve opens sufficiently to compensate for demand, thus maintaining the desired outlet pressure.

LUBRICATORS

Lubricator Dia
Most moving parts require some type of lubrication. The efficiency of cylinders, valves, and air motors can be greatly improved if they are supplied with adequate lubrication.
Air driven devices can be lubricated using an air line lubricator, a device for adding lubricating oil in aerosol form into the compressed air line. The air passing through the lubricator transports the lubricant to air tools, cylinders or other air driven devices where the lubricant is deposited on moving and sliding surfaces to reduce friction and wear.
Most lubricators have a proportional oil delivery feature which automatically provides a nearly constant oil-to-air ratio over a wide range of air flows.

General Purpose/Operation - Micro-Fog Lubricators

Micro-Fog Lubricators inject a finely divided "fog" of oil into a flowing stream of compressed air to automatically provide the proper internal lubrication for air operated tools and other devices. Oil is injected only when there is a flow of air through the lubricator. Micro-Fog density is controlled by the drip rate adjusting knob. Counterclockwise rotation of the knob increases and clockwise rotation decreases Micro-Fog density.

The lubricator utilizes a flexible flow sensor to control the flow of a small amount of inlet air into the reservoir through the fog generator in proportion to the air flow past the sensor. The high velocity air flowing through the generator aspirates oil up the siphon tube into the sight-feed dome, where it drips downward through a needle valve onto the generator. The oil drops are then atomized and mixed with air flowing through the generator into the reservoir. Most of the larger oil particles return to the reservoir. The finer particles (Micro-Fog) remain airborne and are carried through the passage into the downstream system. Only a small portion of the drops visible in the sight-feed dome are delivered downstream to the device being lubricated. The proportionate control afforded by the flow sensor provides a nearly constant oil-to air density ratio over a wide range of air flows. The check ball keeps the siphon tube full during periods of no flow.

Micro-Fog lubricators cannot be filled under pressure unless equipped with an optional "quick-fill" cap or with a remote fill device.

General Purpose/Operation - Oil-Fog Lubricators

Oil-Fog Lubricators inject a "fog" of oil into a flowing stream of compressed air to automatically provide the proper internal lubrication for one air operated tool or other device. Oil is injected only when there is a flow of air through the lubricator.

The lubricator reservoir is pressurized through the charge valve. Whenever there is a flow of air through the lubricator, the flexible flow sensor in the lubricator throat creates a small pressure drop that is proportional to the rate of air flow. The drop in pressure is sensed in the sight-feed dome through the nozzle passage. This establishes a pressure drop across the needle valve which pushes oil upward through the siphon tube into the sight-feed dome where it drips into the nozzle passage and then into the lubricator throat. The adjusting knob controls the oil drip rate. The oil drops are atomized by the air flowing through the lubricator throat and are carried downstream as "oil-fog". All of the drops visible in the sight-feed dome are delivered downstream to the device being lubricated. The proportionate control afforded by the flow sensor provides a nearly constant oil-to-air density ratio over a wide range of air flows. The check ball keeps the siphon tube full of oil during periods of no air flow.

SAFETY
     Dixon's couplings and retention devices are designed to work safely for their intended use.  The selection of the proper hose, coupling, and retention devices; and the proper application of the coupling to the hose are of utmost importance.  Users must consider the size, temperature, application, media, pressure, and hose and coupling manufacturer's recommendations when selecting the proper hose assembly components.  Dixon recommends that all hose assemblies be tested in accordance with the Rubber Manufacturers Association's recommendations and be inspected regularly (before each use), to ensure that they are not damaged or have become loose.
     Safety devices are integral to the coupling and must be working and utilized.  The use of supplementary safety clips and Whipchek Safety Cables are recommended.  If any problem is detected, couplings must be removed from service immediately.
