For more than 30 years, Purafil & Tri-Dim
have provided clean air solutions to commercial buildings,
hotels and casinos
worldwide. Purafil specializes in the manufacture of
air purification systems that remove gaseous/odors and Tri-Dim for
removing particles to ensure a comfortable environment for
patrons and staff.
Sources of airborne pollution are everywhere — from
automobile emissions, people to environmental tobacco smoke. Common
filters trap dust, pollen, and other particles, but only Purafil
gas-phase air filtration systems eliminate gaseous pollutants, the true
sources of poor indoor air quality and odor complaints. For particles
Tri-Dim innovations in air filtration products has lead the way for
higher efficiency & dust load capacities for air filtration
Identifying the Problem:
Airborne Pollution Controlling airborne pollutants is essential to
maintaining a comfortable indoor environment. Pollutants can come from
outside and inside the building.
- Outside sources of particles &
the incinerators, loading docks and waste disposal units, are usually
located at the rear of the building within a few feet of primary HVAC
air intakes. Emissions from nearby industrial facilities or residential
furnaces can also result in complaints from guests and staff.
sources of pollution can include tobacco smoke, restaurants, cleaning
aerosols and bioeffluents from guests. Office furnishings, carpet,
ceiling tile and printers
can worsen indoor air quality.
For clean indoor air, Air Filtration Systems offers an extensive
from all MERV filtration products or pleated chemical filters to
modular front and side access units.
Our air filtration systems are designed for easy maintenance and are
your makeup, supply, or return airstreams.

Hotels & Casinos
Las Vegas attracts people who want to have a great vacation & not
to smell odors or suffer from allergies. There are numerous locations
in hotels and casinos where particle & gas-phase air
filtration systems can be applied so your guest will feel welcome to
come back to your building. To accomplish this we offer a wide range of
adsorbents called media, which are engineered to mitigate objectionable
sulfide, aldehydes, mercaptans, VOCs
aromatic hydrocarbons (PAHs), carbon monoxide, nitrogen oxide,
alcohols, ketones, aldehydes, hydrogen sulfide
Which Air Filtration System Is
Depending on how your building HVAC system is setup will determine what
particle or gas-phase filters you can use. In addition since each
building is as different as the next as to use & construction each
application should be reviewed. Below is a general idea on what
you can accomplish using Air Filtration Systems basic design concept
for an average commercial building.
- Outside Tri-Dim Air Filters
- Return Tri-Dim Air Filters
- Final Tri-Dim Air Filters
- HEPA Tri-Dim Air Filters
- Purafil Media
- MediaPAK™ disposable
Tri-Dim's air filters are standard or can be custom so there is no
limit to what we can accomplish for retrofit of an old building or
meeting the standard current designs. If your building uses outside air
filters for example, then review our suggestion to see if it can help
you, and so forth for the other standard particle filtration sections.
Nevada is known for two things, one of the hottest vacation spots, Las
Vegas. The other lots of desert sand that gets into everything. If
you want to keep from replacing your return-air filters then consider
our Tri-Dek 4-Ply on your outside air instead of using metal filters
supplied by the HVAC manufacture.
Why Tri-Dek 4-Ply
- All Tri-Dek
panels and links are self-sealing, yes filters are suppose to seal!
- Tri-Dek 4-Ply
holds up to 355 grams of dust while a 2" pleat can only get up to 200
grams. (see our Tri-Dek page
for other cost savings Tri-Dek can offer)
- Tri-Dek will
not fall apart due to rain and is Dacron media is very durable.
- OutSide Air
filters are typically easier to replace
- Return Air
Filters will last 2 to 3 times longer.
Bags: Tri-Dek 4-ply has been independent tested in the field to archive
a MERV-10 value. The cool thing about this is achieving everything that
you wish a pleated filter could do, but can't (See Tri-Dek). Here in
Las Vegas we have jobs that have extended the filter service life they
use to get with pleats of 2 to 3 times longer and improved the air
quality in the building. We went from several complaints per month
using our competitor's pleats to no complaints using Tri-Dek for whole
year. Another job our customer went from replacing filters every 3
months to doing them only once a year. The Tri-Dek were tested and
shown that the HVAC units were receiving enough clean air due to the
design of the Tri-Dek.
Bags: If you are pre-filtering your bags and need extra service life to
extend the cost of labor or filter replacement Tri-Dek 4-Ply is a very
good option. Example: we had a local casino that was replacing MERV-13
bags every 3 to 4 months. After installing Tri-Dek 4-Ply we were only
replacing the Tri-Dek 4-Ply 3 to 4 times per year and MERV-15 bags only
once a year.
Bags (Syn-Pac XLII
) is the
final bag filter when it comes to air
quality for commercial buildings. Hybrid resolves many issue synthetic
& fiberglass bags have since they rely on pure mechanical
filtration and not static or by simply design. Also don't be
afraid to adventure into the high MERV Values of 15 or 16 since by
weight the particles the Syn-Pac XLII will stop is nothing in
comparison to the larger particles (see Weight vs Count). In
addition always gasket your bags to seal them from any submicron dust
bypass. Gaskets can be purchased when you order filters or installed on
the frames before you install the bag filters.
customers have asked me to price up an installation of HEPA's to help
control allergies in the office. Odds are HEPA's are an over-kill to
accomplish proper filtration to control allergies. Example – In
most health care facilities the goal is one micron because 99% of all
known bacteria are one micron and larger. If your air filters are truly
sealed the efficiency of the sub micron's will be good enough to
control your indoor air for allergies.
If you have a person that for health reasons requires that extra help
that a HEPA can offer we do have above ceiling units that can clean the
air near the area they work to provide the extra clean environment they
When it comes to gas-phase filtration it really comes down to how much
VOC or gases/odors you can hold or oxidize in your media. Using carbon
alone to control odors just does not do the job required since it just
adsorbs the odors. It takes a Chemi reaction in order to accomplish the
job of removing odors out of the airstream that is being returned back
into the breathable air space in the building. Purafil’s
systems are built-to-order to meet the needs of your budget, space, and
air handling system. We offer solutions for retrofit applications and
offers a broad selection of dry-chemical adsorbents called media, which
are the core of our built-to-order air purification systems. Purafil
manufactures a wide variety of media to remove specific pollutants from
specific sources. Purafil media are packaged in disposable plastic
modules, which are incorporated into front or side access systems.
Purafil media are safe to handle and non-flammable.
cases, we recommend Purafil® SP Blend media because it removes
widest variety of odors and gases. SP Blend is a combination of
Purakol® media, a premium grade activated carbon, and
media, an activated alumina substrate impregnated with the active
ingredient sodium permanganate. While Purakol (carbon) is highly
removing VOCs, it performs poorly against hydrogen sulfide, sulfur
dioxide and oxides of nitrogen. By using these media in combination,
Purafil can ensure the removal of all odors.
offers a broad selection of dry-chemical adsorbents called media that
is manufactured into pleated air filters. Using Purafilters
(MERV-6) in place of your current pleats will control light
building IAQ issues. Purafil has even won the EPA-Award in 2004 for
using Purafilters in its Enersave program that uses the ASHRAE 62.2 IAQ
Procedure for saving up to 30% in HVAC energy. For more information on Enersave click here
|| Purafil Modules
media are packaged into disposable plastic modules. The
disposable plastic module is factory filled with media and comes ready
to be installed. Each MediaPAK holds 0.5 ft3 of media and is easy to
install and replace. In addition to media modules, Purafil’s
purification system also offers a variety of filter options: a MERV 6
prefilter for removal of dust, pollen, and other particulates, as well
as a MERV 13 or MERV 14 final filter to polish air before it enters the
Side Access System
PSA is designed for both particulate and general odor control and works
in conjunction with the facility’s air handling system. The
PSA is a
built-to-order system available in more than 20 size options. A full
range of prefilter selections and particulate final filter selections
are also available.
Front Access System
FAS consists of modular frames that are individually tracked for
Purafil media modules. Frames can be stacked to any size or
configuration to meet any space requirement. The FAS is specified in
retrofit applications with high airflows or for custom air handling
units. Each frame with modules can handle airflows up to 2000 cfm
depending on the model chosen.
