A1586 Main Filter

The pleated and activated carbon filter, captures 98% of particles 0.3µm in size.

Pre-Filter
The pre-filter acts as the initial screening device for Hakko fume extractors. Relatively large particles are removed from the air stream by a polyester filter, similar to those used in home air conditioners. Hakko filters have an arsenate (the capability to collect particles from the air) of 83%. Proper use and maintenance of the pre-filter can extend the service life of the main filter, so it is very important that they be checked at least once a week to see if they need replacement.

Main Filter
The main filter removes contaminants as small as 0.01 micron. This makes it ideal for removing irritating particles that contribute to allergies and asthma. The Hakko filter is made of a closely pleated sheets of waterproof, all-glass paper with aluminum "safe edge" separators. The filter is housed in an aluminum case. Frame joints, separators and the filter itself are sealed to the sides of the case with urethane for a completely leak-tight fit. The filter assembly is stable at temperatures up to 200°F.

Activated Carbon Filter
An activated carbon filter complements the main filter. Activated carbon absorbs nearly all organic and inorganic vapors passing through the filter. Its capacity to remove vapors varies with the concentration of gas in the air, humidity, temperature, and the velocity of the gas passing through the carbon. Efficiency remains constant until the filter is depleted, meaning it has absorbed all the pollutants it can hold.
