DuroPure captures 99%+ of airborne particulates (including hexavalent chromium and heavy metals) and VOCs before recirculating clean air back into the workspace.

The UV light in the DuroPure system acts like sunlight in the natural world, breaking down VOC molecules and rendering them harmless. This is called photocatalytic oxidation. Photocatalysts based on TiO2 (titanium dioxide) promote and accelerate the degradation/breaking apart of organic molecules – including aldehydes, nicotine, methanol, and nitrogen oxides, and contribute to improving air quality. This means the VOC gas molecule breaks apart when it passes by the UV light with TiO2 and becomes carbon dioxide and water. There is not enough water to worry about any accumulation in the equipment, it evaporates.

Absorption: Assimilation of particles through the bulk of a solid or liquid

Example: Liquid soaking into a paper towel

Adsorption: Accumulation of the molecular species at the surface

Example: Water adsorbing onto silica gel, contaminants adsorbing onto activated carbon

• UL/ULC Listed Control Panel
• 1’’ Air Solenoid Interlocked with Fan
• Breathing Ports Provided
• Equipped with VOC monitor to monitor air levels when leaving the exhaust and interlocked with spray air. If VOCs go over the Time Weighted Average Exposure limit (50ppm), the air to the spray gun will shut off but the fans will continue to run with the filters cleaning the air.
• Fused Control Panel (electrician will only need to drop power to the panel)
• System is sized to maintain over the minimum 100 linear feet per minute at the intake filters, therefore keeping the conditions well below the 25% LEL.

No, you don’t need it to run the system. You will still need the compressed air for your spray gun.

The spray gun is interlocked to the VOC monitor. If the VOCs leaving the exhaust are over the Time Weighted Average Exposure limit (50ppm), the air to the spray gun will shut off. Fans will continue to run and the air will be filtered. Please note: The VOC monitor measures air leaving the system so people outside the paint booth and their air is protected. It does not measure VOCs inside the enclosure.

When the VOC levels drop, the air solenoid will reopen and air goes back into the paint gun automatically.

400-500 FPM at exhaust face

100-150 FPM at the interior of the intake filters

In 2013 Duroair had an Industrial Hygiene Assessment During Operation of a Spray Booth Completed by Ontario Enviromental and Safety Network. The study aimed to evaluate the safety and environmental performance of the DuroRoom spray booth equipped with a 13,500 CFM DuroPure filtration system. Multiple air quality and exposure tests were carried out, including sampling for isocyanates, VOCs, carbon monoxide and dioxide, particulates, temperature, humidity, and noise levels. Samples were collected in various areas inside and around the spray booth, and tested by an accredited lab at McMaster University.

One of the key tests focused on Hexamethylene Diisocyanate (HDI), a common compound in spray coatings. Air samples were gathered at three booth locations during active spraying. While HDI oligomers were detected in some aerosol samples, only one sample contained detectable isocyanates—still well below North American occupational exposure limits. VOC testing showed increased concentrations during spraying, though all measurements remained safely within regulatory thresholds. Importantly, the booth was operating under a heavy spraying workload to simulate worst-case conditions.

For indoor air quality, parameters such as carbon monoxide, temperature, humidity, and particulates were measured outside the booth before, during, and after operations. Results confirmed that spray activity did not significantly impact air quality in the surrounding area. Though a sensor error prevented complete CO₂ data capture, levels before the failure remained below exposure limits. Noise testing also showed that sound levels stayed mostly under 60 dBA, with brief spikes likely due to nearby conversation.

In a follow-up test in 2019, Duroair requested sampling to assess for Chromium (CrIII and CrVI) during use of a primer containing strontium and barium chromate. While these substances were present inside the booth during application (as expected), no detectable levels were found outside the booth or on the exhaust discharge side. This confirmed the DuroPure system’s filtration capability was effective at containing hazardous material.

DuroCap™ is a vented air filtration system that’s easily customizable for extracting dusts, fumes, and gasses.

Painting, coating, surface prep, fume extraction

The standard filter package for the DuroCap includes two particulate filters. The stage one filter is a 3 ply panel filter and the second filter is a 3 ply cube filter.

The extra surface area allows for 4 times the particulate capture rate.

Yes, the filters can be customized. The most common customization for the DuroCap is adding a 3^rd stage filter to meet NESHAP 319 requirements.

The exhaust fan pulls contaminated air to the exterior of the building through customer supplied ducting.

400-500 FPM at exhaust face

100-150 FPM at the interior of the intake filters

Compressed air isn’t required to run the DuroCap system but is required to use your spray gun.

Yes, ducting and makeup air is required for the DuroCap and is not provided through Duroair.

The air leaving the building must be replaced. Make up air is what the replaced air is called. If you don’t replace the air leaving the building, the building would then become a negative pressure space. An example of negative pressure is a deflating ballon.

No

In most situations you will need 80-100% of the exhausted air.

Only the control panel is UL/ULC listed.

Only captures particulate. Gases and odors are vented to the exterior of the building.

Duroair can provide clean room solutions up to ISO 6.

The DuroClean can be used for mechanical assembly, 3-D printing, electrical winding, aerospace assembly, and any area requiring a sterile environment.

Can be a positive or negative pressure design.

Negative Pressure: Protects the external environment from processes taking place in the enclosure.

Positive Pressure: Protects your processes from external contaminants. Clean rooms are typically held in positive pressure unless you’re dealing with hazardous products.

Clean rooms are designed to maintain extremely low levels of particulates, such as dust, airborne organisms, or vaporized particles. Clean rooms typically have a cleanliness level quantified by the number of particles per cubic meter at a predetermined particle size.

ISO stands for International Standards Organization. They created the ISO 4644-1 Cleanroom Standards that describe the allowed number of particles, the allowed size of particles and high efficiency particulate absorbing filter (HEPA) filtered air flow changes per hour to meet various ISO levels 1-9. It relies on measurements per cubic meter.

Aside from various filter choices, UV and carbon filters can be added to address VOC and odor concerns.

HEPA stands for high efficiency particulate air filter. It is a pleated mechanical filter that can remove 99.7% of particulate to the size of 0.3 microns.

Duroair has a system to do this. Please reach out for more information.

Yes. If this is integrated into a soft wall retracting enclosure, it will be placed on the back wall. On a fixed or hardwall solution, Duroair engineers will determine the best suitable placement.

This will vary based on the provided solution. Three phase power will need to be brought to the DuroClean by the customer’s licensed electrician. If fire suppression is required, it will need a dedicated 120 V line. Custom ducting may be required for some applications.
