Product Questions & Answers (2)

Question by: Kurt P on Mar 11, 2026, 8:01 PM
got limited space on my air line setup and been looking at piggybacks, how small is this thing exactly?
Answer by: Customer Support on Mar 13, 2026, 8:25 AM
Pretty compact unit. Dimensions come in at 2.21 inches wide and 8.15 inches tall, so it won't eat up much real estate on your line. That's kind of the whole point of a piggyback style, rolling filtration and regulation into one housing instead of mounting two separate units. If you're tight on space, this one fits the bill.
Question by: Shawn R on Jul 2, 2025, 11:02 AM
Reckon this'll hook right up to my current setup? Got a 1/4 NPT already plumbed in.
Answer by: Customer Support on Jul 3, 2025, 4:20 PM
This unit does indeed use 1/4 NPT ports, so it should integrate easily into your existing setup.
