Description
AC Infinity CLOUDLINE PRO S6 – 6" to 4" Adapter & Accessories
This is a simple 6-inch to 4-inch adapter designed specifically for the AC Infinity CLOUDLINE PRO S6 fan.
Both the inlet and outlet are reduced from 6 inches down to 4 inches, making it easy to integrate the S6 into smaller ducting systems. The 6-inch side features an internal taper, allowing the adapter to tighten as it’s pushed on for a snug, leak-free fit without additional clamps.
This adapter is fully compatible with my:
- 90° elbow
- Magnetic quick-connect fittings
Links to those matching components are provided below. Just be sure to install these parts on the 6" to 4" adapter before placing it on the fan
Additional Print Profile Options
Included in the print profiles are several optional accessories:
- Fan Mount Hole Reducers
Reducers for the oversized mounting holes on the fan, allowing the use of standard #6 drywall screws for mounting if desired. - Fan Controller / Remote Mount
A dedicated mount for the fan adjustment controller. I didn’t have a magnetic surface available and wasn’t a fan of the keyed screw slot on the back, so this mount was designed as a cleaner alternative.
Simply apply 3M double-sided tape to the back of the mount and attach it where convenient.
This allows the controller to be easily removed and repositioned closer to you during laser engraving, making on-the-fly fan speed adjustments quick and convenient. Additional mounts can be printed if you’d like controller access in multiple locations.
