Filter Monitors

We have come up with a simplified approach to making filter gauges.  This would be for all Wynn single stage collector filters, as well as homemade plenum boxes.

Needed:

(1) Non threaded, 1-1/4″ PVC pipe cap
(1) 10-24 x 2-1/2″ pan head bolt, with a lock washer and two nuts
(1) nylon hose barb, 3/8″ OD, 1/4″ mip (10 mm x 8 mm)
Silicone, or other sealant
(2) or (3) cotton balls, fiberglass insulation, etc…
(10) or (20) feet of clear vinyl tubing – 1/2″ OD (15 mm) 3/8″ ID (10 mm)

Procedure:

-With a 1/2″ forstner bit, drill one hole in the side of the pipe cap.
-With a 3/16″ drill bit, drill one hole in the top of the pipe cap.  It should be centered.
-With a 3/16″ drill bit, drill (2) holes in the metal filter end-cap (one centered, and the other right next to it).  Holes must not be touching.  See photo.
-Using a dab of silicone sealant, screw the hose barb into the side hole of the pipe cap.
-Using a dab of silicone sealant, insert the bolt through the top hole of the pipe cap.
-Pack the pipe cap with cotton
-Run a bead of silicone around the lip of the pipe cap and insert the bolt into the center hole of the filter end-cap.
-Secure the assembly using the lock washer and two nuts.

That completes the hose attachment point at the filter.  To complete the manometer, see the DIY Tyler video here:
