Product Questions & Answers (3)

Question by: Dale R on Dec 4, 2025, 12:25 PM

how do you go about putting this thing together, is it already assembled or do you have to build it up yourself?

Answer by: Customer Support on Dec 5, 2025, 4:13 PM

It comes as a combination unit with the filter, regulator, and lubricator as modular components. Assembly uses a spacer kit system, so the pieces connect together without much hassle. Standard arrangement runs filter first, then regulator, then lubricator in that order downstream. The T-bracket handles wall mounting once everything is strung together.

got a small 1/4 npt air line, will this frl combo bolt right in and can i hang it on the wall?

Answer by: Customer Support on Apr 11, 2025, 11:44 AM

It uses 1/4 NPT ports and the pieces are modular, so it’s meant to be assembled as a filter, then regulator, then lubricator. Wall mounting is supported with the T-bracket setup mentioned for this unit.
