I reasoned that draining the tank would be all I needed. I was wrong. I soon grew frustrated with moisture coming out of my blow gun, putting moisture in my car tires (which causes damage to your wheels), and seeing moisture coming out of my pneumatic tools. So I purchased this all in one unit. It seemed a bit small when it arrived but it has proven to be a fantastic multipurpose device. It removes the water and any rust, dust, and other trash particles from the getting into the air hose. You simply push up on the valve on the bottom of the bowl to empty. I keep a bucket under the bowl valve to catch to water. The regulator on top is easy to set the desired hose pressure and to change it as needed and locks in place so you don't change it accidently. It is also easy to separate the lubricator from the water filter - which I did. Not all of my air needs needed tool oil in them. I installed a "T" fitting between them that allows me to install a hose fitting for filtered air without passing through the lubricator and then another hose fitting coming out of the lubricator for all my air tools. Adding a couple of shut off valves and simple release valves make it easier to refill the lubricator with oil without having to discharge the entire air system. I installed a second unit just like this one on my pneumatic lift and the lift works better than ever. If you use an air compressor at home or work I recommend you install this unit on it. You won't be disappointed, you'll enjoy your compressor more, and it will be a life saver for your air tools (they require dry, lubricated air). Review: Quality regulator/filter/lubricator combo - Great quality combo Regulator, filter and lubricator. The connection between the two units is solid and they are reversible if your line goes from right to left instead of the "as shipped" left to right. It took me about 10 minutes to make the changes since I needed one of each. Currently have 2 in use with a rapidair system in my garage in conjunction w/ a Husky 60 gal. from Home Depot. As setup: compressor -> 3 ft. 1/2 goodyear whip -> shutoff valve -> to harbor freight regulator/filter combo. - > rapidair manifold. -> to two lines. -> each is split to the IR reg/filter/lube combo and then attached to the rapidair outlet. I'm also running a downtube at each branch for water management. combo appears to work well. I'm running about 115 psi at the tank regulator, and each IR reg combo runs about 90 psi, when active I get about a 5-10psi drop when running depending on the tool. the IR reg/filter/lube combo unit is the best i've seen on the market for the money. It feels solid and well made in stark contrast to the Harbor freight pile that's earlier in the system. Better than the harbor freight pile, cheaper than the Campbell Hausfeld from HD and appears to be higher quality. I'd recommend this unit over any of the other units. It costs more than some and less than others but it's the nicest out there. ## Features - 1/4-Inch NPT - P39124-600 Piggyback Filter/Regulator and L36121-100 Lubricator - Manual drain and polycarbonate bows - Relieving with gauge - 44 CFM ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0057D8LX8 | | Automotive Fit Type | Universal Fit | | Best Sellers Rank | #278,074 in Tools & Home Improvement ( See Top 100 in Tools & Home Improvement ) #18 in Compressed Air Combination Filter Regulator Lubricators #2,598 in Air Tool Parts & Accessories | | Brand | Ingersoll Rand – ARO | | Brand Name | Ingersoll Rand – ARO | | Customer Reviews | 4.4 out of 5 stars 224 Reviews | | Fit Type | Universal Fit | | Global Trade Identification Number | 00663023080925 | | Included Components | Filter-Regulator, Lubricator | | Item Type Name | FRL, Filter Regulator Lubricator Combination | | Item Weight | 1.15 Pounds | | Manufacturer | Ingersoll Rand- ARO | | Manufacturer Part Number | C38121-600-VS | | Manufacturer Warranty Description | 2 Year Limited Warranty | | Model Number | C38121-600-VS | | Number of Items | 1 | | OEM Equivalent Part Number | C38121-600-VS | | OEM Part Number | C38121-600-VS | | UPC | 663023080925 | | Unit Count | 1.0 Count | ## Product Details - **Brand:** Ingersoll Rand – ARO - **Fit Type:** Universal Fit - **OEM Part Number:** C38121-600-VS - **Global Trade Identification Number:** 00663023080925 - **Manufacturer:** Ingersoll Rand- ARO ## Images ![ARO C38121-600-VS Air Filter-Regulator-Lubricator Combination, 1/4" NPT - Image 1](https://m.media-amazon.com/images/I/81THRvm29UL.jpg) ## Available Options This product comes in different **Size** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ A must have for air compressors *by S***N on January 27, 2017* I have used my compressor for sometime without a water separator.

To start out I used regulators from RapidAir. I had three of them and all leaked around the plastic top and eventually around the water bowl. I run a 3/4 regulator at the compressor so the supply is 120psi regulated down to 100 at the machines. That shouldn't be high enough to cause the plastic tops to deform and leak but they did. I made an aluminum brace to better hold the plastic tops straight and that fixed the top leak. I never could get the bowl to stop leaking. New o-ring, good cleaning etc.. still leaked. I picked up two of these and So far they have been doing great. No leaks, the gauge seems accurate and the regulation is spot on. The added bonus of the air injector is great. My mill needed the extra lubrication as the tool changer gets cranky if I don't inject a little oil every once in a while. This saves me from having to bleed the air, disconnect the line and add the oil manually. Happy so far. ## Frequently Bought Together - ARO C38121-600-VS Air Filter-Regulator-Lubricator Combination, 1/4" NPT - Ingersoll Rand 10P Edge Series Premium Grade Air Tool Oil, 0.5 Litre --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/6553301-aro-c38121-600-vs-air-filter-regulator-lubricator-combination-1](https://www.desertcart.co.uk/products/6553301-aro-c38121-600-vs-air-filter-regulator-lubricator-combination-1) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-30*
