Filters, regulators, and lubricators Ingersoll Rand Industrial Technologies

2 For more than 100 years, Ingersoll Rand ARO has been an industry leader in the design and manufacture of compressors, pneumatic tools, and air preparation equipment. Clean air is a key ingredient that enables effective and efficient operation of tools, equipment, and machinery in almost every industry. As such, the use of air preparation devices, such as filters, regulators, and lubricators (FRLs) is an excellent means of keeping your air supply in top condition, as well as enabling your tools and equipment to operate at their peak performance. The new ARO-Flo Series FRLs continue the...

3 Best in class The following regulators were put through head-to-head tests to determine how they compare with the new ARO-Flo Series. Manufacturer Model Number Flow Rate Parker 14R118F 27 cfm Wilkerson® R08-02-F0G0 44 cfm SMC® AR20-N02E-Z 48 cfm Norgren R72G-2AK-RMG 51 cfm ARO-Flo R37121-620 59 cfm How did we do? On average, the ARO-Flo 1/4" 1000 Series regulator flowed 38 percent better than the competition. All regulators were tested under the same conditions, and all units were new — right out of the box. R37121-620 1/4" Regulator — Flow Test 60 50 38% better than the competition CFM...

4 Features and benefits By utilizing a modular lockout valve the user can close off the downstream air supply for maintenance and pressure isolation. Units are threaded for direct plumbing or can be installed in the modular arrangement. Use of modular threaded pipe adapters allow for ease of service by allowing a unit to be quickly removed from the air line. Adapters can be used to pipe different thread sizes in the plumbing setup. Optional filter life indicator works off of pressure differential to show a visible alert when the filter needs replacement. A T-bracket wall mount is standard...

5 1000 Series 1000 Series The oil drip rate is controlled by adjusting the sight dome adjustment screw in a clockwise or counterclockwise direction. The auto-fill option is standard on all ARO-Flo lubricators. Lubricating oil can be added while lubricators are under pressure. Max flow: 59 scfm Series size: Miniature Page: 8 1500 Series 1500 Series The pressure switch is typically threaded into a manifold port block, and allows the sensing of high or low pressure thresholds set by the user. 1/8" and 1/4" Ports 1/4" and 3/8" Ports Max flow: 113 scfm Series size: Compact Page: 18 2000 Series...

6 Overview Filters Regulators ARO-Flo compressed air filters are designed to remove airborne solid and liquid contaminants. Filters can be ordered with different elements, including coalescing models which are capable of removing oil aerosols and particles down to 0.3 micron. Standard filters are sold with 5-micron elements; 40-micron elements can be purchased and installed separately. Air line regulators provide controlled, consistent air pressure as required for specific pneumatic equipment connected to the air system. All ARO-Flo regulators are offered with a standard adjustment range of...

7 Selection When selecting an FRL or individual filter, regulator and lubricator units, the air consumption of the tools or equipment to be serviced should be correlated with the flow capacity of the FRL. ARO Filters, Regulators and Lubricators are designed to flow in excess of that indicated in the maximum recommended flow table shown below. This table gives recommended flows for pipe sizes at listed pressures and should be used as a guide in sizing piping and equipment for compressed air systems. Maximum recommended air flow (scfm) thru ANSI standard weight Schedule 40 pipe Applied...
