Description
Overview
One frame, one rectangular foam pad, both intake fans. Our single-fan filter rings are 132–143.8 mm across and physically cannot sit side by side at the 120.0 mm fan pitch of an S19 or standard S21 — two 127.8 mm circular rims would overlap by 7.8 mm. This frame closes that gap with a single stadium-shaped rim, 240.8 × 127.8 mm, spanning both fans and holding one rectangular pad of filter foam over the pair.
Two honest numbers up front: the foam is not supplied — you cut your own pad — and the grille geometry blocks 18.6% of the opening before any media is fitted. We state that because it is real; no measured airflow figures exist for any part in this line.
What it fits
- Antminer S19 series dual 120 mm intake fan panels.
- Antminer S21 standard (dual 120 mm).
- Any dual 120 mm fan face at 120.0 mm fan pitch with the 105 mm screw pattern.
- It shares its bolt pattern with the dual-120 shroud family — measured to within 0.017 mm.
Measure before you order. Fit dimensions in this line are derived from published fan and chassis geometry and are not yet validated against measured production hardware. Check your flange size and clearances against the footprint below. If something does not fit, tell us — that is how the next revision gets better.
How it is used
Cut a rectangular pad of filter foam (your choice of media — not supplied) to the stadium rim, seat it in the frame, and mount the frame over both intake fans using the eight screw holes. The holes carry a 0.7 mm X-slot that hedges the small published-versus-gasket dispute in the screw pattern (105.0/120.0 vs 105.4/121.0 mm), and a 9 mm access hole sits above each screw so a driver reaches all eight through the frame. Pull the pad out to wash or replace it; the frame stays mounted.
Why it helps
- One part covers both intake fans — the geometry that two single-fan rings cannot achieve at 120.0 mm pitch.
- One rectangular pad to cut and service instead of two discs.
- Driver-access holes over all eight screws — mounting it does not mean losing access to the fan screws.
- Bolt pattern matches the dual-120 shroud family to within 0.017 mm, so it lives on the same machines the shrouds do.
- Honest numbers: the grille blocks 18.6% of the opening before media, and foam is not included.

Frequently asked questions
Is filter foam included?
No — the frame holds the media, you supply it. Cut one rectangular pad to the stadium rim (240.8 × 127.8 mm) from whatever filter foam you prefer.
Does the frame itself restrict the fans?
The grille geometry blocks 18.6% of the opening before any media is fitted — we state that because it is real. What that means for airflow in your setup has not been measured; no flow bench has been run on any part in this line.
Which machines does it fit?
Dual 120 mm intake faces at 120.0 mm fan pitch and the 105 mm screw pattern — the S19 series and the standard S21. Machines with 140 mm fans need the 140 mm single-fan ring instead. Measure your fan panel before you order.
