Description
Possible Match: Automatic Drip‑Leg (Condensate) Drain
These aren’t medical device drains—rather, they’re self‑draining fittings installed at low points (drip legs) in pneumatic/air‑line systems to automatically expel condensate.
Key Product Example: Shako AD940 Series
-
Port Sizes Available: ½”, ¾”, or 1″ (model AD940‑04 is ½”
-
Operation: Fully automatic—no manual draining needed. Without system pressure, the drain stays open, letting all condensate out. When pressure is applied and condensate is present, it automatically opens to drain
-
Pressure Range: 0.5 to 10 bar (tested up to 12 bar)
-
Materials & Build: Body made of aluminum; bowl options include polycarbonate (standard) or optional aluminum; seals are NBR (nitrile rubber)
-
Temperature Range: –10 °C to +60 °C
-
Design Features: Anti‑vacuum design prevents vacuum formation in the pipeline
-
Dimensions (for ½” model): ~69.5 mm wide × 231 mm tall × 77.5 mm deep; weight ~0.5 kg
Another Option: Norgren Drip‑Leg Drain (Part No. AIR000015)
-
Fluid Type: Compressed air
-
Port Size: ½” PTF (pipe thread female) with an automatic drain connection of 1/8″ NPTF female
-
Operation: Automatic. It’s open when unpressurized and closes once bowl pressure reaches ~5 psig (~0.34 bar); reopens automatically to drain when pressure drops below that threshold
-
Pressure & Temperature Ratings:
-
Transparent bowl: up to 150 psig (10.3 bar), temperature up to 125 °F (52 °C)
-
Metal bowl: up to 250 psig (17.2 bar), temperature up to 175 °F (79 °C)
-
-
Materials: Zinc body; bowls (transparent or metal) made of polycarbonate or metal; includes sight glass; internal parts include Acetal, Polyester, Stainless Steel, Neoprene, and Nitrile
