Frequently Asked Questions (FAQs):

Q1: When should I use a 1/2" FRL unit instead of a 1/4" unit?A: You should use a 1/2" unit when your pneumatic tools or machinery require a high volume of air (high CFM). Using a 1/4" unit on a high-demand system will cause a pressure drop and starve the tools of air.

Q2: How do I adjust the oil drip rate on the lubricator?A: There is an adjustment dome or screw on top of the lubricator. Turning it adjusts the drip rate, which you can usually observe through the clear sight dome.

Q3: Can I separate the filter, regulator, and lubricator?A: Yes, this is a modular unit. The components are connected by brackets and spacers, allowing you to disassemble them or add other modules if needed.

Q4: What is the bowl capacity of the AC4000 series?A: The AC4000 series features larger bowls for less frequent maintenance. The filter bowl holds 60 CC, and the lubricator bowl holds 90 CC.

Q5: Does this unit come with mounting hardware?A: Yes, it includes the necessary mounting brackets to secure the heavy unit to a wall or machine frame.
