Ambient Air Cleaners

Ambient Air Cleaners are an economical way to improve the overall air quality in your facility. By continuously filtering ambient air, these air cleaners can reduce the amount of airborne particulate by 80-85% when installed and operated properly.

In addition to improved air quality, filtering tempered air can save thousands of dollars each year on heating and cooling costs when compared to other exhausting methods.

Carbon Filters - Effective Odor Removal

Advanced Filtration for VOCs and Chemical Applications

Carbon filters use activated carbon media to adsorb volatile organic compounds (VOCs), odors, and gaseous contaminants. Ideal for environments dealing with chemical fumes, smoke, and industrial odors, these filters provide enhanced air purification by trapping airborne pollutants at a molecular level.

Pleated Filters – High-Efficiency Particulate Filtration

Reliable Filtration with Maximized Surface Area

Pleated filters offer a larger surface area compared to standard flat filters, allowing for increased dust and particulate retention. Available in various MERV ratings, they efficiently capture airborne contaminants such as dust and fine particulates while maintaining optimal airflow in industrial environments.

Bag Filters – High-Capacity Dust Collection

Deep-Pocket Design for Superior Particle Retention

Designed for high-volume dust collection, bag filters provide extended filter life and high-capacity particulate filtration while maintaining airflow. Their multi-pocket construction allows for deep dust loading, making them an excellent choice for applications with high particulate concentrations, such as manufacturing, woodworking, and welding facilities.

HEPA filters for medical-grade clean air.

HEPA Filters – Maximum Efficiency for Medical Grade Clean Air

Industry-Leading Filtration for Fine Particulate

HEPA (High-Efficiency Particulate Air) filters capture 99.97% of airborne particles at to 0.3 microns, making them the gold standard for air purification. Used in environments requiring the highest level of air cleanliness, such as medical facilities, clean rooms, and industrial settings with fine particulate contaminants.

How Ambient Air Cleaners Work

Ambient air cleaners draw contaminated room air in from both sides of the unit, pass it through a multi-stage filter combination, and exhaust clean air back into the facility — without venting it outdoors. Because tempered air stays inside, you avoid the heating and cooling losses associated with exhaust-based systems.

When units are properly sized for 8–10 air changes per hour, airborne particulate levels drop continuously throughout the shift. Each pass through the filter stack reduces contaminant concentration further, compounding the clean-air effect over time.

Units hung in opposing corners of the facility create a circular airflow pattern — similar to how supply and return vents work in an HVAC system — ensuring even coverage across the entire floor. Ceiling height, room volume, contaminant type, and occupancy all factor into the right configuration for your space.

The 3-Stage Filtration Process

Pre-Filter Stage

A MERV 8 pleated fiber pre-filter captures large particles — metal dust, wood chips, and coarse debris — before they reach the main filter. Protecting downstream media extends overall filter life and lowers total maintenance cost.

Primary Filter Stage

Depending on your model, a high-capacity bag filter (65–95% efficiency), a true HEPA filter (99.97% @ 0.3 microns), or a carbon/charcoal module handles the bulk of particulate or odor removal. Bag filters use a deep-pocket design that allows heavy dust loading without sacrificing airflow.

Return to Room

Filtered air is exhausted back into the facility — not outside — so your heated or cooled air stays in the building. This cycle repeats 8–10 times per hour, delivering a measurable, continuous reduction in airborne welding fume, smoke, and dust throughout every shift.

Installation & Maintenance

Simple & Easy Installation

FumeXtractors industrial air cleaner hung from ceiling brackets in an industrial facility.

No ductwork. No dedicated electrical circuit (single-phase units). Three steps and the unit is running — making ambient air cleaners one of the fastest air quality improvements you can make to an existing facility.

Hang It Up

Three mounting options suit any ceiling type: L-brackets, eye bolt with chain, or strut with chain. Position units in opposing corners to maximize circular airflow coverage throughout the room.

Plug It In

Single-phase OX3000 units ship with a standard 10-ft. power cord — truly plug-and-play. Three-phase variants (OX3500C, OX4000, OX4500, OX7000) require hardwiring by a qualified electrician.

Turn It On

A two-speed toggle switch (Lo / High / Off) on the unit controls fan speed. The switch can be removed and remotely relocated by anyone with appropriate electrical experience.

Affordable & Easy Maintenance

Like any filtration system, filters will accumulate particulate over time and need periodic replacement. The good news: our units use common, standard-sized filters available in case quantities at competitive prices — no proprietary cartridges, no service contracts required.

Typical replacement intervals in a welding or manufacturing environment:

Filter Type	Typical Interval	Notes
Pleated Pre-Filter	1–3 months	Replace more often in heavy-particulate environments
Bag Filter (8 or 12 pocket)	4–6 months	Pre-filter condition directly impacts bag filter life
Carbon / Charcoal Module	6–12 months	Varies with odor load and contaminant concentration
HEPA After-Filter	12+ months	Longest life when upstream filters are maintained

FAQs

Ambient air cleaners work as a secondary system to extract what isn't removed by the primary collection solution to remove welding fumes, particles, and other contaminants from the air in welding environments.

These systems typically draw in contaminated air, pass it through a series of filters, and then recirculate clean air back into the workspace.

Our units typically include a pleated pre-filter, a main filter (which could be a MERV-15 bag filter, HEPA filter, or carbon canisters depending on the model), and an after-filter. Specific filter configurations vary by model.

Filter replacement frequency depends on usage, type of welding, and environmental conditions. Always replace the filters as needed. Typically, on average:
Prefilter: 2-3 months
Bag filters: 4-6 months
Post filters (Hepa filters Carbon filter): 6-12 months

The size depends on the volume of your workspace, type of welding, and frequency of welding. Contact our specialists for a recommendation based on the specific needs of your facility.

Yes, our units are designed to be energy-efficient. By filtering and recirculating tempered air, they can help save on heating and cooling costs compared to exhausting methods.

Noise levels vary by model but are generally designed to be quiet. For example, some of our 1100 CFM models operate at just 50 dBA at 5 feet.

Most of our units operate on standard 115V/1PH/60Hz power, with amp draws ranging from about 4.5A to 9.5A depending on the model.

We provide a 2-year warranty on parts (excluding filters) for our ambient air cleaners.
