Aro-Flo Series Air Line Filter/Regulator/Lubricator Combination Unit, 1/4 NPT Ports, 61 SCFM Flow Rating, Manual Drain

Description & Features

The Aro-Flo Series Air Line Filter/Regulator/Lubricator Combination Unit 1/4 NPT Ports 61 SCFM Flow Rating Manual Drain offers a robust solution for maintaining pneumatic systems in industrial settings.

This versatile unit includes a modular design with a T-bracket wall mount ensuring easy installation and maintenance. The manual drain feature allows for straightforward expulsion of contaminants contributing to system reliability.

The 1500 Series provides effective filtering of airborne solid and liquid contaminants and includes a coalescing filter option for removing oil aerosols and particles down to 0.3 micron. Standard 5-micron and optional 40-micron elements ensure flexible filtration.

Regulators maintain consistent air pressure designed for a standard adjustment range of 0-140 psig. ARO-Flo mist-type lubricators guarantee proper oil distribution prolonging equipment lifespan and reducing wear.

Filter-regulator units or piggybacks combine both filtering and regulating functions in a compact design ideal for constrained spaces. Installation procedures dictate the sequence should follow filter regulator and lubricator order to ensure optimal performance.

Engineered with polycarbonate components and a bowl guard this unit guarantees durability and strength in demanding work environments. The flow rating of 61 SCFM provides ample capacity for various applications.

Question by: Larry P on Jan 12, 2026, 12:51 PM

got a compressor feeding a few air tools in the shop and lookin at this unit, does it handle the filtering, pressure control, and oiling all in one shot or do I need to buy extra pieces?

Answer by: Customer Support on Jan 13, 2026, 4:18 PM

All three functions come built into this one assembly. The filter stage pulls out solid particles and liquid contaminants from your compressed air line, the regulator holds your pressure steady anywhere in the 0 to 140 psig range, and the mist-type lubricator keeps a consistent oil supply moving to your downstream tools. The three components in this combination are the F35221-400 filter, R37221-600 regulator, and L36221-100 lubricator, and they ship together as a ready-to-install unit. One thing worth knowing is that they need to be installed in that specific order, filter first, then regulator, then lubricator, going downstream. That sequence matters for the system to work right.
