Airwasher

7inch x 12.5inch x 12inch high – 175 x 320mm x 300mm high T6c-Airwasher

The project of the last 2 years  is completed and several of these miniature industrial Airwashers are now being used by friends and my family members. They are testing it’s operation under real conditions of cleaning the air in their homes and to offer their critique on it.

The funnel to the left of the scrubber power  head is for an upended 2 liter soda pop bottle to supply additional makeup water as it evaporates and to maintain the proper operating water level within the machine. see below.

T6c Airwasher

With the supply bottle in operation the machine draws 58 watts of power as it cleans about 60 cubic feet of air a minute, while trapping the pollutants in the 4 liters of water in the clear acrylic plastic tank  bellow it.

With the exception of the water tank and the 2 Liter “pop” bottle, all of the plastic parts were created out of about 1 kilogram,  2+ pounds,  of ABS plastic on a small Desktop 3D Printer from files created with a desktop computer. Truly a manufacturing empire on my kitchen table! …pg

up date: 4 August,  refinements to the scrubbing rotor have reduced the power consumption from 58-60 watts to  48-50 watts, increased the air flow, and reduced the sound levels it produces. I am now re-manufacturing the motors to improve their ability to support the rotors weight as it is many times heaver then the pump impeller that the motor was designed for.  …pg
