HOW OFTEN DO I HAVE TO CHANGE MY FILTERS?

HOW OFTEN DO I HAVE TO CHANGE MY FILTERS?

For filter life each application is completely different.It depends on the materials you are working with, and how often you are creating particulate.  For instance in Laser applications the depth you are cutting / engraving, the laser wattage, the type of material you are working with are all factors. Typical applications have the pre-filter being changed approximately every 1-3 months, HEPA filter 6-12 months, chemical filter 6-12 months.  This is just a guide as some end users last much longer and some also consume the filters much quicker.

WHAT IS A HEPA FILTER?

HEPA filters, by definition, remove at least 99.97% of airborne particles 0.3 micrometers (µm) in diameter. Some manufacturers use HEPA material in their filters and claim that these are HEPA filters. Quatro Air certifies our filters as HEPA which means that they go through a vigorous testing procedure and meet medical standards for filtration.

HEPA filters are composed of a mat of randomly arranged fibres. The fibres are typically composed of fiberglass and possess diameters between 0.5 and 2.0 micron. Key factors affecting function are fibre diameter, filter thickness, and face velocity. The air space between HEPA filter fibres is much greater than 0.3 μm. The common assumption that a HEPA filter acts like a sieve where particles smaller than the largest opening can pass through is incorrect. Unlike membrane filters, where particles as wide as the largest opening or distance between fibres cannot pass in between them at all, HEPA filters are designed to target much smaller pollutants and particles. These particles are trapped (they stick to a fibre) through a combination of the following three mechanisms:

  1. Interception, where particles following a line of flow in the air stream come within one radius of a fibre and adhere to it.
  2. Impaction, where larger particles are unable to avoid fibres by following the curving contours of the air stream and are forced to embed in one of them directly; this effect increases with diminishing fibre separation and higher air flow velocity.
  3. Diffusion, an enhancing mechanism is a result of the collision with gas molecules by the smallest particles, especially those below 0.1 µm in diameter, which are thereby impeded and delayed in their path through the filter; this behaviour is similar to Brownian motion and raises the probability that a particle will be stopped by either of the two mechanisms above; it becomes dominant at lower air flow velocities

Diffusion predominates below the 0.1 μm diameter particle size. Impaction and interception predominate above 0.4 μm. In between, near the 0.3 μm MPPS, diffusion and interception predominate.

The filter resistance to flow is known as its pressure drop

WHAT IS THE LASER BLUE GEL?

We are proud to introduce our new breakethrough technology. We call it the LASER BLUE GEL. This sleek blue design is nothing like the regular gasket you may find in other filtration units on the market. Due to it’s elasticity, it allows zero bypass to any fumes, odors and VOCs. It’s NON toxic and NON porous as well

WHAT ARE VOCs?

Volatile organic compounds (VOCs) are organic chemical compounds that have high enough vapor pressures under normal conditions to significantly vaporize and enter the atmosphere.Volatile organic compounds are numerous and varied. Although ubiquitous in nature and modern industrial society, they may also be harmful or toxic. VOCs, or subsets of the VOCs, are often regulated.

VOCs may be natural or synthetic. Like organic chemicals in general, there are millions of different compounds which may be classified as VOCs. The compounds the nose detects as smells are generally VOCs. Modern industrial chemicals such as fuels, solvents, coatings, feedstocks, and refrigerants are usually VOCs.

As organic chemicals, VOCs may have health consequences, but this is depending on the specific chemicals that are part of the umbrella definition “VOC”. For indoor air purposes, there are long lists of limit values[1] published by German AgBB, French AFSSET, and California EPA (“CREL”). Because they tend toward the gaseous state, management of toxic VOCs is more difficult than with non-volatile compounds. Human exposure to VOCs can be through contact with the solid, liquid, or gaseous forms, inhalation of the gaseous form, or ingestion of the liquid form or solutions containing the VOC.

Because of their health effects, VOCs are regulated in some places. The large number of VOCs combined with their numerous exposure pathways make comprehensive management, discussion or regulation of volatile organic compounds impractical. Instead, subsets of VOCs are regulated by a wide variety of governmental agencies.
