Laser cutting | Sticky Smoke | Premature clogging

Sticky smoke

is what we sometimes call the by-product when cutting or engraving on resinous materials such as acrylic, wood, materials with adhesive backing, etc. They consume filters sooner rather than later 🙂

Here’s where our Pre-filter modules that can be added on our Laser Fume Extractors or ordered as a stand-alone to complement your existing laser fume extractor / air filtration system.

Designed to enhance the performance of the SPH800/SPH400 air purifiers, the PF800/PF400 passive pre-filter modules capture larger dust and particles protecting the air purifier’s HEPA and/or carbon filter.


Who needs it?

Customers that have heavy dust loadings will appreciate this pre-filter section since it will prolong the life of the primary filters inside the SPH800/SPH400 extractors, reducing the maintenance costs.

What’s inside?

The PF800/PF400 modules contain three (PF800) or two (PF400) high-capacity antimicrobial, multilayered, dust filter bags that can capture a significant amount of dust and particulate matter before it reaches the primary filters of the SPH800/SPH400 units.

How easy is it to change the filters?

Whether you have a standalone or add-on module filter bags are accessed in the same manner. Remove inlet cover, quarter turn 4 locking mechanisms and remove the section to replace bags. Designed to be clean simple and effective. Dust is contained in the bags to
minimize the mess and exposure of personnel to potentially harmful dust.

How can I use it?

The PF800/PF400 passive pre-filters can be used either as add-on modules to an SPH800/SPH400 air purifier or as standalone mobile units. The standalone modules, can be used with virtually any existing filtration system. The inlet and discharge collars can accommodate many different arrangements to suit the application. Single or dual 1”, 1.5”, 2”, 2.5”, 3” or 4” diameter collars are available as standard options. Custom diameters are
available upon request.

Dimensions: H x W x D

PF800: 30 x 16 x 25 (in) / 76 x 40 x 64 (cm)
PF400: 24 x 12 x 15 (in)  / 76 x 30 x 38 (cm)

Laser Cutting | Safety concerns when cutting MDF | Laser Fumes Smoke Extractor

Safety concerns when cutting MDF

When MDF is cut, a large quantity of dust particles are released into the air. It is important that a respirator is worn and that the material is cut in a controlled and ventilated environment. It is a good practice to seal the exposed edges to limit the emissions from the binders contained in this material.

Formaldehyde resins are commonly used to bind together the fibres in MDF, and testing has consistently revealed that MDF products emit free formaldehyde and other volatile organic compounds that pose health risks at concentrations considered unsafe, for at least several months after manufacture.[7][8][9]

[ More of the above article – ]

Be forewarned – cutting MDF and similar wood products consume particulate filters quickly

Unfortunately certain woods such as MDF (containing glues, adhesives , resin) will consume filters quickly.

If you work with these materials lots we suggest getting the PF400 – – the pre-filter bag section is incorporated into the CSA600 series.

PF400S Pre-Filter Section

  • Multiple high density layered antimicrobial filter bags x 2
  • Easy to change
  • Large holding capacity
  • Self contained pre-filter section can be combined with any existing system that requires additional particulate filtration
  • Can also snap onto existing SPH400 system

Resins in wood

The resin could be in the wood itself or if many layers are bonded together the bonding adhesives / glues could be the culprit. Essentially the laser vaporizes the adhesive or resinous material which then condenses / sticks and clogs the filters rapidly.

Sometimes it is the natural resins within a particular wood.

When this type of material is lasered the fumes can sometimes block the pores of the filters. This will not be unique to Quatro’s filters but to any unit that contains particulate / HEPA filters.

Installing a pre-filter section may prolong the life of the HEPA filters. It all depends on what type of debris is being generated in the particular application.

For those unfortunate to have an application where HEPA filters are being blinded quickly we have two items we can offer:
1) The PF400A pre-filter section $653.00
2) Part # AG189 (box of 6 HEPA’s for the price of 3) ……… $351.00 USD
