The materials used in the new Canless Air System O2 Hurricane ESD-safe units have been tested and proven to measure in the static dissipative range, around 10 E+9 ohms, and are acceptable for use around ESD sensitive hardware. The new units have the same power as the Canless Air Industrial unit and are rechargeable up to 500 times. This means that not only are they ESD-safe, but they produce no hazardous waste. This product fills a crucial need, as one of the dangers of using a conventional duster in a clean room is that the static it produces can cause damage to solid state electronic components and integrated circuits. Our new ESD-safe units eliminate that costly and dangerous variable. This product is equal to over 1000 cans of canned air, computer duster, air duster, gas duster, compressed air or whatever other names companies put on their chemical filled electronic cleaners. It is also perfect for people who use air compressors but don"t want to be tethered with a cord. We offer a 30 day risk-free return policy, we even pay the return shipping if you don"t love it, so try it now!
