AZtech T-3500 Ambient & Industrial Air Cleaners

AZTech T-3000

Our ambient air flow experts designed the Aztech T-Series Industrial Air Cleaners for fume extraction, welding smoke collection, industrial dust extraction, oil mist filtration and the capture of most airborne nuisance dusts, mist and vapors. These simple, yet effective, industrial air cleaners have a two stage air filtering system; Merv 7 pre-filters and Merv 15 multi-pocket main bag filters. Additional industrial air purifier pre-filter options include filter saver pads, spark baffles and a variety of other filter media designed to match the size of dust particles or help better control wet oily smoke and oil mist. Industrial Maid designed the T Series in a modular configuration, allowing for air purifier units to be built in a number of vertical, horizontal or even quad configurations. This is the industrial ventilation system designed to fit your specific application and budget.

Our ambient air flow experts made the interior frame of this ambient room air cleaner out of a rugged powder coated steel. The ambient air filtration system's cabinet shell can be a powder coated steel or an environmentally friendly 3/16” black matte recycled polyethylene plastic.

Proper air to cloth ratios and careful calculation of airflow patterns and rates will help protect your workers, protect your assets, save energy dollars and keep your shop clean, safe and running efficiently. Contact us for more information about our industrial air purifiers.

Featuring Both Commercial Air Purifiers and Industrial Air Cleaners

Short Description

Featuring light weight environmentally friendly polyethylene cabinet panels, with a rugged 16 gauge steel frame, the AZTech T-Series ambient air cleaners are lower in cost, non-corrosive, run quieter and resist dents and scratches. No ducting is required in most applications, so no mechanical contractor is required. Easy to order, easy to service disposable filters provide for simple low-cost maintenance. Four inch Merv 7 pleated industrial pre-filters catch the larger particles, which extends the 2nd stage Merv 15 multi-pocket bag filter's life. These ambient air filtration systems can be easily relocated to accommodate growth or space redesign and are perfect for setting up the popular push-pull industrial air filtration system design.

Saves you $$$

With the AZTech T-Series ambient air filtration systems, you never have to pay to heat or air-condition air, only to exhaust it to the outside in an attempt to provide clean air for your workers. With AZTech industrial air cleaners, a blower pulls contaminated air from the work area through a set of highly efficient air filters that separate out harmful particles. The filtered air is then re-circulated back into the room. Standard size filters and lower horsepower ratings are additional money saving features.

Multiple Options for Installation – Multiple Duties

T-Series ambient air filtration systems are designed to accommodate a variety of installation methods making them the easiest industrial air purifier to fit to your specific application. They can be hung with chains, mounted with all-thread rods, or installed using optional wall brackets. Some of the most popular applications for the self-contained AZTech units are welding fume ventilation, grinding dust, diesel smoke, oil mist, granite dust and composite dust. Optional HEPA and charcoal filters are available for more demanding industrial ventilation system applications.

At Industrial Maid we are very proud of our "workhorse" the T-Series. The use of a T-style industrial air cleaner configuration offers key advantages for "free hanging" air cleaning sytems.

Available Configurations for T-Series

Dual Intake - Twice the normal intake area of a straight-through industrial air purifier (more intake helps create a better airflow pattern)

Dual Filters - Nearly twice the filter media of straight-through fume collector (longer filter life and filter service intervals)

Air Angles - Clean air throw is 90° from the intakes allowing for better air patterns (factory wall can be used as a barrier to channel air filtration dust into the intakes)

At Industrial Maid we use the newest technology to design and manufacture industrial air filtration equipment to improve the air quality in commercial and industrial facilities. Rated from 1,000 to 8,000 CFM, our ambient air cleaners offer a modular design that can be configured to collect welding smoke and fumes, grinding dust, oil mist, vapors and other nuisance dusts to fit your specific needs.

With a Merv 15 (95% @ .5 micron) main bag filter or an optional HEPA final filter, welding fume, diesel smoke, even the heaviest oil mist is no match for our two and three stage packaged industrial ventilation systems. And thanks to their modular design our industrial air filters can be stacked in a number of vertical, horizontal or quad configurations.

Step 1
Determine the AER – Air Exchange Rate from Table 1 that best fits your application needs.

Step 2
Determine the total cubic feet of your plant work area
Total cubic feet = L x W x H (maximum height 20’)

L = length of your workspace (feet)
W = width of your workspace (feet)
H = height of your ceiling in the workspace (feet)

Note - we use dimensions only to 20 feet as smoke, dust and fumes will stratify well below this height. Example: 24 ft ceiling height—20 ft.

Step 3
Divide the total cubic feet by the AER determined in Step 1.

Step 4
Divide this total by the CFM of the unit you prefer to use.
T-3000 is 3000 CFM
T-3500 is 3500 CFM
T-4500 is 4500 CFM
T-6000 is 6000 CFM
T-7500 is 7500 CFM

Workspace is 100’ long X 60’ wide X 18’ tall
Total cubic feet is: 100 X 60 X 18 = 108,000 cubic feet

Welding application
Medium use 5 as the AER (air exchange rate)
(from Table 1) 108,000/ 5 = 21,600

Assume using a T-3500 (3500 CFM unit)
21,600/3500 = 6.17 or 6 units to handle the application.

Step 5
Determine best location or placement for units.

Our qualified staff is always available to help you determine CFM requirement, placement and then final selection of the units that will provide you the best "cost of ownership" in regards to electrical consumption and filter service costs. Contact Sales @ (877) 624-3247

*Source capture may be required to meet OSHA, PEL or TWA requirements. General guidelines only, consult factory for specific details.

T-7500x2 7500 CFM Ea.

Mining Equipment Manufacturer
T-7500x6 7500 CFM ea.

A large mining equipment manufacturer placed 28 - T 7500 X 6 units in their main bay welding areas. The units are controlled by a variable speed package and set up on a six month service cycle. This application has saved energy, helped control the smoke and fumes from heavy welding and provided a solution that is much less expensive than a central dust collection system – both in initial purchase price and the cost of day-to-day operation. No compressed air is required and maintenance is a breeze. With no dust dump trays or barrels to fuss with and a low energy consumption rate, Industrial Maid is proud to add another customer to our list of clients who are pleased with their product choice.

Precise Fabrication
T-4500x2 4500 CFM ea.

A metal fabricator with a new 41,000 sq foot, air-conditioned building needed to extract welding smoke and fumes from several welding stations. The 130’ X 40’ area was enclosed with steel panels and safety curtains. Four of our T-4500 X 2 units were installed, offering a combined 18,000 CFM of cleaning capacity. Clean air is exhausted outside the welding stations while fresh air is pulled in below the curtain area. A dual laser-cutting station in the same facility is equipped with T-3000 units to also protect workers in that area.

A satisfied customer knows that the HVAC system is not being exposed to any extra dust or smoke particulate, the plant remains clean, and most importantly the production staff is protected.
