The 1625 laser requires airflow to protect the output window. An internal pump and
filters provide the correct flow and pressure. The air filters are designed to remove dust,
neutralize acids in the air, remove hydrocarbon compounds that could cause thermal
lensing of the beam and dry the air. The main filters are at the pump input. There is a
final filter inside the laser that is designed to last the life of the laser assuming that the
pump filters are maintained.
The main filters are repurposed vacuum cleaner filters made by Arm & Hammer. These
outer fi
lters are made to fit “Bissell” number 10 and 16 vacuum cleaners. These filters
can be bought from Iradion, sourced locally at Walmart stores or ordered online. The
inner filter (see filter diagram) also serves as a sound muffler for the air pump.
Operation without this filter will result in high noise levels and may cause a fault. The
inner filter is an air dryer and can also remove oil and dust. The outer filters are
designed to remove the bulk of the dust and neutralize acids generated by laser
engraving certain organic materials like wood. The carbon in these filters absorbs
hydrocarbons gases that can cause thermal lensing of the beam.
The outer filters can be washed in water. It is recommended to wash the outermost
foam filter if it gets visibly loaded with dust. It is critical that any washed filter be
completely dried before use to avoid rapid exhaustion of the inner dryer filter that must
be replaced if the blue color fades away.
The inner dryer filter has a life of between 300 and 700 hours of pump time. The
humidity of the air determines the filter life. This filter should be checked every 300
hours of operation by removing the outer filter and checking that there is some blue
color left in the filter window.
