Powerful, compact and portable, the Quatro Air Purifier series provides optimal containment of dust, odors, and airborne particles left after polishing operations and various bench work. Many competitive dust collectors pick up much of the dust at the source, but polishing operations also allow a substantial amount of dust to become airborne and settle around the shop thus why Quatro Air Purifiers are needed to sweep the air and contain.

Fresh-Air Series Air Purifiers capture airborne dust and other contaminants in an advanced three-stage filtration system (see breakdown below), then recirculate clean air back into the room. The most important stage of this filtration system is the medical grade certified HEPA filter, rated at 99.97% at 0.3 microns. The brushless motor is designed for long continuous use and provides quiet operation. All provide complete room air exchange approximately 15 times per hour (depending on the room size). While these air purifiers purge the air and provide a clean environment, they will also help reduce heating and air-conditioning energy/maintenance costs as well as reduce general cleaning costs. Each includes smooth casters for easy relocation from room to room as well as (3) spare dust filters. Replacement Filters for all models are available, see related products below. Available in 3 sizes based on the size of your room. See "Specifications" for details on individual models. Made in Canada.

All units feature a 3-stage filtration system:

  • Stage-1 Prefilter — Captures the biggest particles, prolonging the life of subsequent filters. Inexpensive and easy to change.
  • Stage-2 Hi-Cap Filter — Provides high-capacity particle retention.
  • Stage-3 HEPA Filter — Picks up 99.97% of 0.3 micron particulate, including soot and pollen. Recirculates clean air back into the room to help minimize heating and AC costs. Replace every 3 to 5 years depending on use.

HEPA (High-Efficiency Particulate Air) filters are designed to capture the submicron particles that tend to pass straight through traditional Ashrae-rated filters. These particles—which can come in the form of powders, aerosols, fumes, smoke, molds, spores, bacteria and more—bypass the human respiratory system’s natural defenses, penetrating deep into the lungs where they cannot be expelled and raising long-term health concerns. For this reason, HEPA filters are critical to ensuring safety in environments where small particulate is generated. It is no coincidence that allergists, asthma specialists and air filtration specialists alike recommend HEPA filtration.

Note: When working with materials that contain silica, such as investment or tripoli, it is wise to wear a properly-rated respirator if exposure levels are high. Airborne respirable silica can be captured with a vacuum or air purifier containing a HEPA filter.
