Airwolf Delivers Long-Lasting Wet Vacuum Pump
Airwolf’s wet vacuum pumps use oil-mist lubrication from the engine crankcase, strong pump vanes, and computer-assisted machining and milling to ensure reliability. Airwolf Filter recently completed certification testing required by the FAA for its new 400 Series wet vacuum pump. The 400 Series is a follow-on to Airwolf’s 200 Series wet pump launched last year and is applicable for piston aircraft fitted with deicing boots. The Series 200 pumps drive the vacuum system and the Series 400s also activate the deicing boots. This new pump is currently in production with the first units ready to ship at this writing. Airwolf guarantees its wet pumps for 2,000 fight hours or 10 years. The 400 Series wet pumps replace all 400 Series dry pumps, regardless of manufacturer, with no modifications necessary for installation. Airwolf Filter, 440-632-5136, www.airwolf.com
Sontara Towels Prevent Scratching
You probably wouldn’t dream of throwing your old shirt or jeans in the shop towel pile knowing that a forgotten button or zipper could cause damage. Even dedicated shop towels often retain grease and dirt after washing. DuPont has an alternative when you need to take your cleaning to a higher level, Sontara Multipurpose Shop Towels.
Sontara fabric has short lengths of fiber that form a strong three-dimensional sheet structure. It is a nonwoven textile unlike traditional fabrics because its fibers are not spun into yarns and woven or knitted. The manufacturing process for Sontara also doesn’t use any binders, surface modifiers, or adhesives to hold the fibers together, which minimizes the possibility of product contamination.
Sontara shops towels are pure, low-linting, strong, and absorbent (or repellent depending on the type). The textured shop towel is best for picking up oil, paint, resin, and other thick or gooey liquids. The smooth shop towel is suitable for glass surfaces and works well in picking up low-viscosity fluids. Both stand up well to autoclaves, solvents, most cleaning fluids, and are very strong wet or dry. DuPont Sontara, 888-476-6827, 615-847-7656, www.sontara.com.
Sensitive Ice Probe
Operators of turbofan engines can save fuel and reduce engine damage by activating the engine anti-ice at the moment of optimum efficiency. A new ice-detecting transducer probe has been developed by New Avionics of Ft. Lauderdale, Florida to achieve just such efficiency. The probe detects ice with a sensitivity of 0.001 inch and alerts pilots to the presence of inflight icing before it becomes a hazard.
The probe contains no moving parts and is completely solid, making it able to withstand plus or minus 25 G in all six axes. It is made of 316L marine-grade stainless steel, hermetically sealed, and operates at almost any altitude. The probe has been tested and calibrated by NASA, and DVD footage is available documenting the probe’s successful operation within 10 seconds of entering icing domains aloft.
Four wires connect the transducer probe to its operating circuit, which is radio silent and uses no megahertz clock. It runs on 3.3 volts DC and consumes less than 100 milliamps. Remote sensing is accomplished by separating the tiny transducer probe from its electronic circuitry by as much as a meter. The probe weighs only one-quarter ounce. In lots of 50 units or more, units are priced at $799 each. Operating schematic, layout, and low-cost bill-of-material are all provided under license. 954-568-1991, www.newavionics.com.
