Activated Carbon Air Filter

This is a carbon filter designed to filter the air in enclosed spaces where a resin printer is operating. It is designed for an 80mm computer fan, The internal carbon capacity holds exactly 600gm of activated carbon, the fan sucks the air from the outside, through a filter paper and the carbon, and is expelled upwards through the fan. The outer filter surface is a porous florist paper, which can be remove for cleaning, or can be cleaned in place with a vacuum, the filter paper is held in place with 2 compression rings with tension provided by rubber bands. The lid is held in place on the body with a small lip on the edge of the body. This design maximises the air volume and carbon density Specification of the fan that I usedBrand: NIDECAppearance size: 80 x 80 x 38mmRated voltage: DC12VVoltage range: DC7.0V-13.6VInput power: 0.9A (nominal current)Rated speed: r.p.m 1800-5600Temperature range: -10.. 70 degrees CLife expectancy: 25 L10 C is expected to be 50000 hoursBearing structure: ma
